1. Executive Summary

This Capability Statement presents the Oman Electricity Transmission Company’s development plans for the

400kV, 220kV and 132kV transmission systems for the years 2012 to 2016.

The Statement includes data for the generators, loads, overhead lines, cables, transformers and capacitor banks

used in the development of transmission system models for the power system studies undertaken with OETC’s

DIgSILENT power system analysis software, version 14, in preparation of this Capability Statement. The

Statement also includes the results of power system analysis of the transmission system that defines system

performance when operating under the extremes of peak and minimum demand in each of the five years. From

this analysis an assessment has been made of the opportunities for the connection of new generation and new

demand on the system.

Table 1 lists the schedule for committed and planned system development projects on the 400 kV, 220 kV and

132 kV transmission systems, although it should be noted that not all of the projects listed have full authorisation

at this time. Implementation of these system development projects will increase the number of 220/132 kV grid

stations from eight to fourteen before the summer peak of 2016, with an additional installed firm grid substation

capacity of 6,000 MVA. The number of 132/33 kV grid stations will also increase from the forty-six in service at

the beginning of 2012 to sixtey five by the summer peak of 2016. In 2010 the company has introduced direct

voltage transformation from 132 kV to 11 kV on the transmission system with respective 132/11 kV substation

for the major residential/tourism developments at Azaiba Coast (Wave Project) in Muscat area.

In addition, during 2012 the company introduced direct voltage transformation from 220kV to 33kV on the

transmission system with respective of 220/33 kV substation for the major residential/tourism developments at

Blue City in Batinah South area.

It is also one of OETC’s strategic planning concepts to complete a 220kV double circuit ring around northern

Oman. In 2010 the 220kV connection between the Sohar Interconnector Station (SIS) and Mahadah (Al-Wasit)

was completed to help in linking the main load centre in Oman (Muscat) with the UAE (Abu Dhabi Transco) and

the rest of the GCC Grid via Sohar and the rapidly developing Sohar port and industrial area. By the year 2012

the 220kV transmission systems will also be extended from Misfah in the Muscat area to Jahloot and further

eastwards to Sur. In addition, OETC plans to complete building a 220 kV line between Mahadah to Ibri before

summer 2012 to support the voltage and meet the expected load growth in the area.

Morever, OETC will introduce the first 400kV system which includes 400kVconnection between Jahloot grid

station and Sur power station, 400kV connection between Sur power station and Izki grid station and 400kV

connection between Izki grid station and Misfah grid station. Four 400/220kV grid stations will be installed at

Sur, Jahloot, Izki and Misfah areas.

In accordance with Condition 27 of OETC’s Transmission Licence, the power flow studies presented in this

Capability Statement are based on demand forecast data provided by the Oman Power and Water Procurement

Company (OPWP) as per its recent Seven-Year Statement. The forecast has been disaggregated by grid station,

according to available Distribution companies (DISCO) data, for detailed power system analysis.

To be able to perform the studies and produce the results presented in this statement, the Strategic Planning and

Studies team has set a deadline to receive data from various parties (OPWP, DISCO, OETC internal departments)

as per the Grid Code requirements. Any information received after the deadline will be included in the next Five-

Year Annul Transmission Capability Statement (2013-2017).


Page | 8

In order to model future system development as accurately as possible the distribution companies are required by

the Grid Code to provide OETC with information that identifies their load transfer plans, including the load to be

transferred, the timing and the grid stations involved, data that is also provided to OPWP for its own forecast of

generation requirements. From the individual demand forecasts of the distribution companies, OETC has

developed its own demand forecast inline with most of distribution companies provided system forecast for the

transmission system as a whole, including the load transfers between grid stations that are then incorporated into

the power system models for each year.

The forecast average annual growth in system demand of about 10.22 % over the period 2012 –2016 drives many

of the planned grid station reinforcements with a large portion of the additional demand supplied to the

distribution companies through the 132/33 kV grid stations. To meet security of supply requirements and provide

load relief to the heavier loaded grid stations it will be necessary to transfer excess load to the new or existing grid

stations. Comparison of the demand forecast with generation availability as defined in the latest OPWP Seven-

Year Statement shows sufficient availability in generation capacity after introducing the new generating capacity

from Barka Phase-3 (750MW), Sohar Phase-2 (750MW) and Sur IPP (2000MW).

As the demand grows, there is a greater need to extend the 220kV transmission systems so that bulk power is

transmitted at this voltage rather than 132kV in order to avoid overloads, improve voltages and reduce power

losses. Consequently, it is OETC’s objective to operate 220kV as the main transmission voltage and use 132kV

for sub-transmission.

From Table 1 a total of 54 transmission projects are planned over a five year period, most of projects are designed

to increase the transmission system capacity so that it can meet future growth in demand and satisfy the security

criteria. This is a major programme of capital investment in its infrastructure that will be spread across the whole

network to improve transmission system performance across northern Oman. Power system studies presented in

this Statement confirm that the planned investment in 400/220 kV, 220/132 kV and 132/33 kV grid stations and

transmission circuits will provide substantial spare capacity on the transmission systems to well beyond 2016.

The major technical issue identified in the studies was with high short-circuit fault levels on the 132 kV bus bars

at 4 grid stations in the Muscat area. The grid stations at Ghubrah, Bousher, Rusail and Madinat Sultan Qaboos

(MSQ) were all shown in earlier studies (OETC Five Year Capability Statement 2008-2012) to have high 132 kV

fault levels. Accordingly, OETC has taken appropriate remedial action to address this problem by implementing

in the short–term, measures to split the 132 kV bus bars at Rusail and Ghubrah.

In 2011, the 132 kV bus bars were split at Rusail and Ghubrah power stations to reduce the short circuit current

with zero cost. This will be continued in 2012.

In 2013 Rusail will no longer need splitting due to the network development and reconfiguration works which

will take place to facilitate the addition of new IPPs, and therefore the Rusail bus bars will be returned to normal

operation. In 2014, many generating units at Ghubrah power plant will be retired and no more splitting will be

needed.

Load flow studies have confirmed that the voltage levels across the transmission system can be maintained within

the ±10 % limits as defined in the Grid Code.

At Al Hail and at other remote locations, such as Sur at the eastern end of the transmission system, there is a

strong case for the deployment of reactive compensation as a cost effective means of improving the system

voltage. Similarly, with the demand in the Muscat area continuing to grow there are occasions when some grid

stations in the Muscat area suffer reduced voltages at times of heavy load. To overcome this problem, Muscat

Electricity Distribution Company (MEDC) has installed new capacitor banks on the 33 kV bus bars at Bousher,

MSQ, Mawalleh, Mabellah, Qurum, and Jahloot grid stations in 2010 and these capacitor banks produced a

significant improvement in the voltage profile across the Muscat area. Also, Majan and Mazoon Distribution

Companies have installed capacitor banks at some places in their network. With these capacitor banks the voltage

profile has been significantely improved.

The voltage problems experienced in the Al Dhahirah area has led OETC to review its plans for system

reinforcement to this area with the 220 kV system extended from Mahadah (Al Wasit) to Ibri, with Ibri scheduled

upgraded before the 2012 peak. When this work is completed, the transmission system in this area will be fully

compliant with the voltage requirements set by the Grid Code and the Transmission Security Standard

requirements set by Licence Condition 26.

The Statement has reviewed the opportunities for the connection of new generation and new demand and

identified those grid stations with substantial spare capacity where it should be possible to connect new demand to

the system.

Section 2 of the Statement provides an introduction to the document, identifying the main related documentation

and the key changes that have taken place on the transmission system since the previous issue of the Statement.

Section 3 identifies the technical requirements of the Grid Code and the Transmission Licence with specific

attention to system voltage, frequency and security of supply.

Section 4 describes the main engineering standards used by OETC in its planning and design of the transmission

system.

Section 5 describes the existing transmission system and summarises the planned developments in each year over

the period 2012 to 2016.

Section 6 identifies the existing and planned developments in generation and describes the interconnections both

inside Oman and internationally, i.e. PDO and the UAE (Abu Dhabi Transco) respectively.

Section 7 presents the demand forecast and compares this with the generation capacity available.

Section 8 discusses transmission system performance and presents the results of load flow and short-circuits

studies that show the performance of the transmission system at both maximum and minimum peak demand in

each year from 2012 to 2016.

Section 9 identifies the development opportunities for the connection of new demand and new generating plant to

the transmission system.

Section 10 presents the areas of the network where network components will be operating above firm capacity

during the period 2012 - 2016 and identifies the need for new or renewed derogations from application of the

Transmission Security Standard.

2. Introduction

2.1 Licence conditions, Codes and Standards

This Transmission System Five-Year Capability Statement covers the period 2012 – 2016 which has been

prepared by the Oman Electricity Transmission Company S.A.O.C. (OETC) in accordance with the

requirements set down under Licence Condition 27 of the Electricity Transmission and Dispatch Licence

granted to the Company on 1 May 2005 by the Authority of Electricity Regulation (AER). The Licence

has been granted under the powers invested in the Authority by Article (2) of the Law for the Regulation

and Privatisation of the Electricity and Related Water Sector promulgated by Royal Decree 78/2004.

The purpose of the Statement is to provide up-to-date transmission system data for potential and existing

users of the transmission system so they can identify those parts of the transmission system which offer

the opportunity for future development. The Statement is required to be updated annually so that users

and potential users of the transmission system are furnished with the latest information.

Potential users of the transmission system should be aware of the following main documents that

influence the planning and future development of the transmission system infrastructure:

i) The Grid Code for the Sultanate of Oman.

ii) The Electricity Transmission and Dispatch Licence granted to OETC, notably Licence

Condition 26, which defines the requirements for the Security Standards and the

maintaining of an Efficient and Economic Transmission System.

iii) The approved Transmission Security Standards prepared in accordance with Condition 26

of OETC’s Transmission and Dispatch Licence.

iv) The Statement of Charges for Connection to the OETC Electricity Transmission System.

v) The Statement of Charges for the Use of the OETC Electricity Transmission System.

2.2 System Development since the 2011-2015 Statement

Since the issue of the previous Capability Statement, covering the period 2011 – 2015, the following

projects have been or will be completed and energized in time to meet 2012 system peak demand:

1. Installation of fourth 125 MVA transformer at 132/33 kV Bousher Grid Station.

2. Construction of the 132/33kV grid station at Yitti and the associated 132 kV transmission system.

3. Construction of the 132/33kV grid station at Qurum and the associated 132 kV transmission

system.


Page | 25

4. Construction of the 132/33kV grid station at Muttrah and the associated 132 kV transmission

system.

5. Replacing of the wooden pole O/H lines with steel tower between Mahadah (Al Wasit) and

Bureimi grid stations.

6. Construction of the 220/33kV grid station at Blue City.

7. Installation of third 125 MVA transformer at 132/33 kV Barka Main Grid Station.

8. Upgrade Seeb Main 132/33kV grid station from 2 x 63 MVA to 2 x 125 MVA transformers.

9. Upgrade of Dhahirah system from 132kV to 220kV.

10. Construction of 220kV grid station at Sohar for the new Sohar-2 IPP.

11. Construction of the132/33kV grid station at Quriyat and the associated 132 kV transmission

system.

12. Reconnection of 132kV lines within Muscat Area.

13. Construction of Misfah 220kV and Barka grid stations and installation of required O/H lines.

2.3 Improvements in the preparation of the Statement

Since the issue of the Transmission System Capability Statement for 2011 – 2015 there have been a

number of improvements in the data and the power system modelling upon which the studies that are

discussed in the Statement are based. The most significant of these are:

i. The Statement presents solutions of all problems reported in the Five Year Capability

Statement (2008-2012). By the end of the period covered by the present Statement,

problems of line and transformer loadings, voltage, and fault current issues will be

completely removed.

ii. The OETC demand forecast is based on the data provided by the OPWP and distribution

companies.

iii. Updating the rating of OHL and underground cable conductors. The rating of the double

circuit 132kV OHTL with 400mm2 AAAC twin-Yew conductors according to the Oman

Electrical Standards OES-32 is 300MVA, while the value used in previous capability

statements is 261MVA and the rating of the double circuit 220kV OHTL twin-Araucaria

conductors is 673MVA, while the value used in previous capability statements is

762MVA. These changes because of the updated calculation for the overhead lines

currents taken into consideration Oman climate condition such as; Wind speed ( ), Solar

irradiance ( ), Ambient temperature ( ), Emissivity factor ( ) and Solar absorption


Page | 26

coefficient ( ). The updated values of the line rating in this statement represent the worst

weather condition with low wind speed and emissivity factor and with high solar

irradiance, ambient temperature and solar absorption coefficient. These values will be used

for the planning propose and in the real operation the weather condition is better and the

lines can take more power when the wind speed is high and ambient temperature is low

(the updated values will not have any implications on connected costumers or power

plants).

iv. Detailed representation of Sohar Aluminum power plant in the Model.

v. Updating Barka-3, Sohar-2 and Sur power plants’ data.

vi. Updating the operational limits of generating units according to the received information

from the OPWP.

The improvements in the demand forecast and the power system modelling should result in similar

improvements being achieved in the accuracy of the power system studies upon which network

development planning is based.


Page | 27

3. Technical requirements for compliance with the Grid Code and Licence

In order to comply with Condition 26 of the Electricity Transmission and Dispatch Licence the

transmission system must be planned, designed and operated to provide a secure, efficient and economic

supply of electricity that is of an acceptable quality to its users.

Whilst Condition 26 specifically sets out the Security of Supply requirements, the most important

characteristics that determine the quality of supply are frequency and voltage. The requirements for

maintaining transmission system frequency and voltage within specified operating limits are set out in the

Grid Code, and most clearly defined under conditions CC.6.1.1 and CC.6.1.2 respectively of the

Connection Conditions Code.

Other issues that relate to the planning of an economic and cost effective transmission system that

provides a voltage supply of acceptable quality, such as standardisation of equipment ratings, limitation of

system losses, and the control and limitation of disturbing factors that affect the voltage waveform are

covered by relevant Omani and/or International Standards.

3.1 System Frequency

In accordance with condition CC.6.1.1 of the Connection Conditions Code, OETC is required to maintain

System Frequency within the following limits:

a) During normal operating conditions, the nominal system frequency of the transmission

system shall be 50.00Hz and will be controlled normally between 49.95Hz and 50.05Hz.

b) During exceptional steady state conditions, frequency deviations will not exceed 49.90Hz to

50.10Hz unless disturbed circumstances prevail.

c) Under disturbed conditions, system frequency could rise transiently to 51.50 Hz or fall to

48.0 Hz, but not exceed these limits.

As CC.6.1.1 points out, the frequency of the total system is responsive to changes in the balance between

the active power demand and total available generation capacity. OETC must therefore ensure that

sufficient generation capacity and demand is available and connected to the system at all times to respond

automatically to active power imbalances and correct any frequency change.

3.2 System Voltage

In accordance with condition CC.6.1.2 of the Connection Conditions Code, OETC is required to control

system voltage within the following limits:

a) The voltage on the 220 kV and 132 kV parts of the Transmission System at each site with a

user connection will remain within the limits of ±10% of the nominal voltage level.


Page | 28

b) The voltage on the 66kV, 33 kV and 11 kV sides of transmission transformers at

Connection Sites with Users will normally remain within the limits of ±6% of the nominal

value unless abnormal conditions prevail.

During some system disturbances, such as where short circuits occur, the voltage could collapse

transiently to zero at the point of fault until the fault is cleared.

Voltage regulation requires both active and reactive power flows across the transmission system to be

carefully controlled. The physical characteristics of the plant on the transmission system also give rise to

the generation and absorption of reactive power. Reactive power flows across the transmission system

can give rise to substantial voltage differences and it is therefore necessary to maintain reactive power

balances between sources of capacity and demand on a “zone” basis.

Unlike frequency, which is consistent across an interconnected transmission system, voltages at different

points on an interconnected system are determined by the local sources of demand and capacity, by the

prevailing network configuration and by the reactive power flows across the network.

The management of voltage requires control of reactive power and centrally dispatched generators,

transformer tap-changers, can provide this by the connection of capacitor banks at 33 kV or below, or by

means of static compensation.

3.3 Security of Supply

In accordance with Condition 26 of the OETC Transmission Licence the capacity of the Transmission

System to transmit electricity shall not be reduced in the event that a single electric line, cable,

transformer, circuit breaker and/or associated plant is not in service, provided that during a period in

which such single electric line, cable, transformer, circuit breaker and/or associated plant is not in service.

The operating voltage of the Transmission System may reduce to any level specified from time to time for

such purposes in the Grid Code. In effect, the transmission system should be planned and operated to

meet the Transmission Security Standard requirements.

The Transmission System taken over by OETC in 2005 had several components that failed to meet the

Transmission Security Standard requirement, and the Licence recognised that it might take two years.

However, by system peak 2013 all grid stations and overhead lines will meet most of required standards

and criteria to bring the whole system into full compliance. To date some of these out of firm situations

have been addressed, but equally the steep growth in demand has caused further circuits / transformers to

become out of firm. Section 10 summarizes the system grid condition.


Page | 29

4. OETC System Design and Planning Standards

In addition to the technical requirements of the Transmission Licence and the Grid Code, the principal

electrical standards used by OETC in its planning and design of the 220 kV and 132 kV transmission

systems are:

4.1 Oman Electrical Standard OES 11

The standard covers the topic “General Specifications for Electrical Materials and Equipment” and

defines the worst case conditions for system design purposes by the following parameters:

a) maximum ambient temperature (50˚C)

b) maximum surface temperature for metal surfaces (80˚C)

c) altitude (between sea level and 30 metres above sea level)

d) maximum wind velocity (125km per hour)

e) average annual rainfall (100mm)

f) maximum relative humidity (100%)

The standard also defines the design parameters for the 132 kV systems in terms of highest voltage

(145 kV), design fault level (31.5 kA) and the requirement that the system be solidly earthed. Currently it

does not specify corresponding figures for the 400 kV and 220 kV systems.

4.2 Oman Electrical Standard OES 25A and 25B

These standards define the requirements for aluminium conductor steel reinforced and aluminium alloy

conductor overhead lines and aluminium alloy stranded conductor overhead lines.


Volume 1 of the standard covers the design requirements for a 132/33 kV, 2 x 125 MVA substation with

132 kV gas insulated switchgear, including the 33 kV switchgear. Volume 2 covers similar requirements

for the 132/33 kV, 2 x 63 MVA substation with 132 kV outdoor SF6 switchgear.


The standard covers the design requirements for 132 kV double circuit overhead transmission lines with

400mm2 All Aluminium Alloy Twin Conductors (AAAC) on lattice steel towers that are deployed across

much of the 132 kV transmission system.

4.5 Other Standards

In cases where an Omani Standard is not applicable it is usual OETC practice to adopt the appropriate

IEC Standard. This particularly applies to the design of the 400kV and 220 kV transmission systems.

5. OETC Transmission System

5.1 Existing 220/132 kV Transmission System

The Oman Electricity Transmission Company is authorized to undertake all regulated activities of

electricity transmission and dispatch in northern Oman at voltages of 132 kV and above. The existing

transmission system has two operating voltages, i.e. 220 kV and 132 kV. It extends across the whole of

northern Oman and interconnects bulk consumers and generators of electricity located in the Governorate

of Muscat and in the regions of Batinah, Dhahirah, Dakhliyah and Sharquiya.

The transmission system was first established under the Ministry of Electricity and Water (MEW) in 1983

and underwent rapid expansion during the 1990s. Consequently much of it has less than 15 year service

experience. After the electrical sector was unbundled, the OETC took over the operation of the

transmission system on 1 May 2005.

The present OETC transmission system consists of:

1344.6 circuit-km of 220 kV overhead transmission lines

3061.46 circuit-km of 132 kV overhead transmission lines

55.4 circuit-km of 220 kV underground cables

98.68 circuit-km of 132 kV underground cables

7630 MVA of 220/132 kV transformer capacity




Five 220 kV interconnection grid stations

Two 220/132 kV grid stations

One 220/33 kV grid station

Six 220/132/33 kV grid stations

Forty 132/33 kV grid stations

One 132/11 kV grid station

The transmission system is interconnected at 220 kV from Mahadah (Al Wasit) grid station with the

transmission system of UAE (Abu Dhabi Transco) and through this interconnection it will form part of

the GCC Grid that links the electricity supply systems of Kuwait, Saudi Arabia, Bahrain, Qatar, UAE and

Oman. This should provide increased security of supply and benefits to the member countries in the form

of cost savings from the sharing of reserve capacity and energy resources. The interconnector has been

energised and brought into service in Q4 2011.

The OETC transmission system is also interconnected with the Sohar Aluminum system at 220 kV via a

double circuit cable line that runs between SPS on the OETC system and Sohar Aluminum 220kV busbar.


Page | 31

Under normal conditions the power transfer across the interconnection is forecasted to be negligible, but

in the event of an emergency on either network the interconnection can facilitate a power transfer of up to

300 MW to address the shortfall.

The OETC transmission system is also interconnected with the PDO transmission network at 132 kV via

a single circuit overhead line that runs between Nizwa on the OETC system and Nahda on the PDO

system. Under normal conditions the power transfer across the interconnection is forecasted to be

negligible, but in the event of an emergency on either network the interconnection can facilitate a power

transfer of up to 60 MW to address the shortfall.

The transmission system is supplied with electricity generated from ten gas-based power stations located

at Ghubrah, Rusail, Wadi Jizzi, Manah, Al Kamil, Barka (ACWA), Barka SMN, Barka III, Sohar I and

Sohar II. In addition the transmission system may be supplied from direct customers, such as Sohar

Aluminium, PDO, Sohar Refinery, OMCO and OMIFCO.

Three Distribution Licence holders, i.e. Muscat Electricity Distribution Company (MEDC), Mazoon

Electricity Company (MZEC) and Majan Electricity Company (MJEC), take the bulk of the power

transmitted through the main grid, from the 220/132/33 kV, 220/33kV, 132/33 kV and 132/11 kV grid

stations.

In addition to the three distribution companies, ten large private customers are directly connected to the

transmission system. Six of these are connected to the transmission system in the Sohar Industrial Area.

The existing private customers are:

220 kV Connections

i. Sohar Aluminium Smelter

ii. Shadeed Steel

132 kV Connections

i. Sohar Industrial Estate

ii. Sharq Steel

iii. PDO

iv. OMCO

v. Aromatics

vi. Sohar Refinery

vii. OMIFCO

The following new customers will be directly connected during the period covered by the Statement:

Sun Matel (Zoom load) will be connected with the 220 kV Sur IPP grid station in 2015.

The New Muscat International Airport (Ministry of Transport) will be connected to

Airport Heights grid station in 2012.

Muscat Steel will be connected with 132kV Rusail grid station in 2013.

Modern Steel will be connected with 132kV Rusail grid station in 2015.

In 2011, the system gross peak demand was 4000MW which occurred at 15:00 hours on 18 June, an

increase of 10.68 % on the 2010 peak demand. During 2011, the Electric Energy Delivered (EED) to the

MIS system from connected generating plants was 18,924,219 GWh whilst that exported from the MIS to

the distribution companies was 18,507.886 GWh resulting in transmission system energy losses of

416.333 GWh, which equates to a transmission system energy loss of 2.25 %.

5.2 Future System Development Projects

The power system studies presented later in this Capability Statement and used to define the constraints

and opportunities that exist on the transmission system over the next five years have been performed on

the basis that the committed and planned development projects detailed in Appendix A and summarised

below will proceed as planned and be completed to the current schedule.

5.2.1 Projects completed to meet the 2012 peak demand

A geo-schematic diagram of the existing transmission system in 2012 is shown in Figure 1. In section 2.2

of this Statement it was noted that a number of projects had been completed since the 2011– 2015

Capability Statement was published and that the new works were being energised so that they were

available to meet the peak demand in summer 2012. These projects will provide load relief to some of the

heavily loaded grid stations and transmission circuits in addition to improving the voltage profile. The

projects designed to meet the 2012 system demand include a new 132kV grid station at Muttrah, Qurum

Yitti and Quriyat. And new 220kV grid station at Blue City, Sohar-II IPP, Misfah and Barka-III IPP. The

upgrade of the 132 kV double circuit line between Mahadah (Al Wasit) and Bureimi. Also, the

replacement of overhead lines with underground cables in Muscat area. A number of grid stations cannot

maintain the Transmission Security Standard requirement and additional 125 MVA third transformer

capacity is being provided at Barka Main, a fourth transformer of 125MVA capacity is added at Bousher,

and the upgrading of Seeb Main transformers from 2 x 63 MVA to 2 x 125MVA to meet the demand in

2012.

Other major projects scheduled for that period are the 220 kV systems which will be extended into the Al

Dhahirah area. These include construction of a new 220 kV double circuits overhead transmission line

from Mahadah (Al Wasit) to Ibri, where a new 220/132 kV, 2 x 500 MVA Ibri grid station will be


Page | 33

established. This project will help in transferring the flow of the bulk electric power to the more efficient

220 kV system, thus improving the voltage profiles in this area, and reducing power losses. Also,

construction of new 132 kV line between Ibri and Dank and upgrading Ibri transformers to 125 MVA.

The main investment to meet the 2012 peak is in the extension of the 220 kV transmission systems from

Barka-III IPP to Misfah grid station. The new IPPs at Barka and Sohar will be connected to the 220 kV

transmission system through new 220 kV GIS substations at Barka-III and Sohar-II. Sohar-II will be

connected to SIS (Sohar Interconnector Station) at 220 kV via a double circuit connection. However, part

of the route near the power station will have to be run underground because of difficulties in obtaining a

right of way for another overhead line.

5.2.2 Projects expected to be completed to meet the 2013 peak demand

Figure 2 shows in geo-schematic form the system development plan to meet the demand in 2013 peak

demand. The new projects scheduled for completion in time to meet the summer peak demand in 2013 are

at various stages of development and the major projects for which a consultant has been appointed for

construction. The projects designed to meet the 2013 system demand include a new 132/33kV grid station

at Ghubrah, Ayjah, Sur, Hamriyah (Wadi Adai-2) and upgrading of Jahloot to 220kV. The upgrade of the

132 kV double circuit line between Dank and Al Hail grid station will be completed by 2013.

Further upgrading projects are also required at Izki grid station from 2x40MVA to 2x125MVA

transformers, Mudhaibi grid station from 2x63MVA to 2x125MVA transformers, Dank grid station from

2x15MVA to 2x63MVA transformers and Rustaq grid station from 2 x 63 MVA to 3 x 125 MVA

tarnsformers. Sur power station Phase-1 220kV GIS installation is scheduled to be completed to meet the

system demand in 2013.

The main investment to meet the 2013 peak is in the extension of the 220 kV transmission systems from

Misfah to Jahloot and on to Hamriyah (Wadi Adai-2) and Sur grid stations. To cater for future growth in

demand, consideration is being given to constructing Sur-Jahloot line for operation at 400 kV, but

operating initially at 220kV. The other major projects planned for completion before summer 2013 are the

new 220/132 kV, 2 x 500 MVA grid stations to be established at Sur, Al Hamryah and Jahloot.

5.2.3 Projects expected to be completed to meet the 2014 peak demand

Figure 3 shows in geo-schematic form the system development plan to meet the 2014 system peak

demand. The new projects scheduled for completion in time to meet the summer peak demand in 2014 are

at various stages of development and the major projects for which a consultant has been appointed for

construction. The projects designed to meet the 2014 system demand include the construction of new

132/33 kV grid stations at Ghala (Madinat Al Arfan), Buremim-2, adding third and fourth transformers at

Sohar, Madinat Nizwa, Al Kamil & Al Wafi, Madinat Barka, Al Amerat, Mabellah-2 (Al Khoudh) and

Al Khadra. Other projects that are required to meet the 2014 system demand are replacement of 132kV

GIS at Rusail, replacement of 132KV AIS to GIS at Mahadh (Al Wasit), adding two 220kV GIS bays at

Mahadah (Al Wasit) grid station to connect the GCC link between Oman and UAE, linking Al Falaj,

Muttrah and Wadi Kabir grid stations by one circuit, new 400kV overhead line between Sur Power Plant


Page | 34

and Izki 400/220/132kV grid station. Further upgrading projects are also required at Sumail and Shinas

grid station from 2x63MVA to 2x125MVA transformers.

The other major project planned for completion before summer 2014 is replacement of 132kV Seeb-

Mawalleh overhead line to underground cable and adding new 132kV GIS at Mawalleh to connect Seeb

Main and Airport Heights grid stations and adding fourth transformer of 125MVA capacity at Mawalleh

grid station. Another major project planned for operating the 220 kV line between Jahloot and Sur grid

station to 400 kV with the new 400/220 kV gird stations to be established at Jahloot and Sur. This line is

planning to operate to 400 kV to evacuate the full power from Sur power plant (2000 MW).

5.2.4 Projects expected to be completed in time to meet the 2015 peak demand

Figure 4 shows in geo-schematic form the system development plan to meet the 2015 peak demand. One

of the major projects expected to be connected to the transmission system by summer 2015 is the

construction of new 132kV grid station at Free Zone, Ibra, Hajarmat, adding third and fourth transformers

at MIS and Muladah, upgrading MSQ from 132kV to 220kV and adding fourth transformer of 125 MVA

capacity at MSQ grid station (MSQ-B), adding fourth transformer of 125MVA capacity at Wadi Kabir

grid station (Wadi Kabir-B), upgrading Liwa to 220kV and new 400kV Overhead lines between Izki and

Misfah with 400kV GIS, 400/220kV at Misfah grid station.

5.2.5 Projects expected to be completed in time to meet the 2016 peak demand

Figure 5 shows in geo-schematic form the system arrangement to meet the 2016 peak demand. A project

expected to be connected to the transmission system by summer 2016 are converting 132kV OHL Nizwa-

Ibri to 220kV in addition to 220kV Overhead line to Izki grid station and new 220kV grid station

connected to Mobailah-1 by LILO Filaj-Airport Heights OHL.

5.3 Summary

Table 1 in the Executive Summary has summarised the development plans for the OETC Transmission

System on a project by project basis at the time of this Statement. The table identifies the projects to

which OETC are already committed and those projects that are considered likely to proceed.

The power system studies presented later in this Capability Statement to show the expected performance

of the transmission system over the period 2012-2016 have been performed on the basis that the

committed and planned development projects in Table 1 and detailed in Appendix A will proceed as

planned and to be completed on schedule. The system studies are used to identify areas of the

transmission system where there are opportunities for connecting new demand and new generation and

where constraints should be applied to further development.

6. Existing and Planned Developments in Generation

6.1 Existing generation

The OETC transmission system in 2012 will be supplied by ten gas-based power stations:

Ghubrah and Rusail in Muscat region (Muscat Electricity Distribution Company supply area).

Barka (ACWA), Barka SMN and Barka III in Al Batinah South region, Manah in Al Dakhilya

region and Al Kamil in Al Sharqiyah region (Mazoon Electricity Company supply area).

Sohar I and Sohar II in North Al Batinah region and Wadi Jizzi in Al Bureimi region (Majan

Electricity Company supply area).

The ten power stations are described briefly below:

a) Ghubrah Power and Desalination Plant

The initial development of Ghubrah Power Station started in 1976 and the installation of the

power and desalination plant was accomplished in six phases, four of which included the

commissioning of new generating units. The layout of the site is complex and is a mixture of

thirteen gas turbines and three steam turbines of various ratings. The net generation capacity is

approximately 447MW.

b) Rusail Power Station

Rusail Power Station is located in the Rusail Industrial Estate. The power station has eight Frame

9E gas turbines installed and operating in open-cycle. The gross site rating of the units varies

from 81.5 MW to 95.9 MW. The units were installed progressively between 1984 and 2000. The

net generation capacity of the power station is approximately 687 MW.

c) Wadi Jizzi Power Station

recently) and was developed as an Independent Water & Power Plant (IWPP). The

power plant comprises two Ansaldo V94.2 gas turbines (manufactured under licence from

Siemens) and a steam turbine operating in combined cycle. The net generation capacity

is approximately 434MW.

2. The Barka II SMN plant is an Independent Water & Power Plant (IWPP) and was

commissioned in 2009. There are three gas turbines of 130 MW capacity each and two

steam turbines of 161 MW capacity each. The total net generation capacity is

approximately 681 MW.

3. Barka III Power Plant is an Independent Power Plant (IPP) and is commissioned in early

2012. There are two gas turbines of 247.5 MW capacity each are available in 2012 and a

steam turbine of 249.9 MW capacity which will be available in 2013. The total early

generation capacity is approximately 494.9 MW in 2012.

g) Sohar Power and Desalination Plant

1. Sohar I Power and Desalination Plant was also developed as an IWPP by the Sohar

Power Company. The plant consists of three Siemens V 94.2 gas turbines (Ansaldo

Extraction Type), a steam turbine and four desalination units. The three gas turbines

came into service during summer 2006. The net power plant capacity is 605 MW.

2. Sohar II Power Plant is an Independent Power Plant (IPP) and is commissioned in early

2012. There are two gas turbines of 247.5 MW capacity each are available in 2012 and a

steam turbine of 249.9 MW capacity which will be available in 2013. The total early

generation capacity is approximately 494.9 MW in 2012.

Table 2 lists on a yearly basis the existing and committed future generating capacity over the period 2012-

2016. The table presents the gross and net maximum capacity for each generating unit at each power

station and takes account of the desalination load where appropriate.

6.2 Planned Retirements of Existing Plant

There are a number of planned retirements of the existing units in 2012 and further retirements are

planned before 2014. The planned retirements are as follows:

a) Ghubrah Power and Desalination Plant

In 2013, it is planned to retire the existing units GT1-9 (144 MW). In addition, ST4 (37 MW),

GT10 (26.3 MW) and GT11 (26.3 MW) will be retired in 2014.

b) Wadi Jizzi Power Station

In 2015, it is planned to retire the existing units GT4 (29.8 MW), GT5 (29.8 MW) and GT8

(29.1).

6.3 Planned future generation (2012 – 2016)

There are three main generation developments planned for the period 2012 to 2016:

a) Barka III Power Station (IPP)

Barka III Independent Power Plant (IPP) has been commissioned recently. There are two gas

turbines of 247.5 MW capacity each are available in 2012 and a steam turbine of 249.9 MW

capacity which will be available in 2013. The total net generation capacity will be 744.9 MW in

2013.

b) Sohar II Power Station (IPP)

Sohar II Independent Power Plant (IPP) has been commissioned recently. There are two gas

turbines of 247.5 MW capacity each are available in 2012 and a steam turbine of 249.9 MW

capacity which will be available in 2013. The total net generation capacity will be 744.9 MW in

2013.

c) Sur Power Station (IPP)

Sur Independent Power Plant (IPP) will be commissioned in 2013 and 2014. There are five gas

turbines of 244MW capacity and only two (217MW each) will be available in 2013. In 2014 the

total capacity will reach 2000MW working in a combined cycle with two steam turbines of

311MW and one steam turbine 157MW.

Table 3 summarises the net capacity of the additional future generating plant over the period 2012 to 2016

assumed in this Capability Statement. The table shows that an additional 3500 MW of generating

capacity from these plants is planned to be in service before the 2014 peak.

6.4 Non Contracted Generating Capacity

There are a number of private industrial customers directly connected to the transmission system that

either operate or plan to operate their own on-site generation. The largest generating plant among these is

Sohar Aluminium, which may export up to 300 MW.

The interconnected system and the private customer generating plants can with the customer’s agreement

be made available to support the contracted generation under emergency conditions in order to avoid

power cuts in northern Oman because of a shortfall in the contracted generation. These generators are

termed “non-contracted” generating plants. Table 4 shows the non-contracted generating capacity

6.5 Interconnections

6.5.1 Interconnection with the UAE (ABU DHABI TRANSCO) and the rest of the GCC

Grid

The 220 kV transmission interconnection with the United Arab Emirates (Abu Dhabi Transco) was

completed in the first quarter of 2007. The interconnection connects Mahadah grid station (Al Wasit) to

Al Foah grid station in Al Ain in the UAE. The interconnection is via a 220 kV double circuit overhead

transmission line with twin Araucaria.

In the longer term the principal technical benefit to be obtained from connecting Oman to the GCC Grid

is in a reduced spinning reserve requirement, which will be shared between the members of the

GCC Grid. However, operation of the interconnection will allow Oman to import/export power from the

GCC Grid to meet any potential generation shortfall.

6.5.2 Interconnection with PDO

The OETC transmission system is interconnected with the transmission system of the Petroleum

Development Oman (PDO) which provides electricity to its sites across the central region of Oman for the

purpose of oil exploration and development. The interconnection is made at 132 kV between Nizwa grid

station on the OETC system and Nahda 132 kV substation on the PDO 132 kV network by a 67 km


Page | 47

overhead line with a single Elm. The over head line is owned by PDO. Under normal conditions the

power transfer between the two networks is allowed to float around zero MW, with power transfers

balanced out over a period. The interconnection essentially allows OETC and PDO to share spinning

reserve and supply limited power to each other in emergency conditions on either system.

6.6 Economic Dispatch

The Load Dispatch Centre of OETC dispatches generation based on its availability as stated by the

Generator on a day-ahead basis, and its price as listed by the Oman Power and Water Procurement Co.

(OPWP). Under circumstances where the system frequency is seen to stray outside the specified limits,

LDC will issue dispatch instructions to Generators based on Merit Order to rectify the situation.

6.7 Spinning Reserve

The Load Dispatch Centre strives to maintain a spinning reserve equal to the rating of the largest

generating unit connected to the transmission system.

7. Demand Forecast and Generation Availability

7.1 System Demand

Maximum demand usually occurs on the OETC transmission on a weekday in the months of May, June or

July, during a period of particularly high temperature and humidity. The growth in air conditioning

equipment in domestic and commercial premises in Oman has ensured that peak demand usually occurs

during the afternoon. Figure 6 shows the 24-hour demand profile for the transmission system on the day

of the 2011 system peak demand (i.e. 18/06/2011). The 2011 system peak demand of 4000.3 MW was

recorded at 15:00 hours by the OETC Load Dispatch Centre. The historic growth in system peak demand

over the period (2003-2011) is shown in Table 6.

Minimum demand generally occurs on the transmission system during night-time in December/January

when electricity consumption in all major load categories is reduced. In 2011 the system minimum

demand was 909 MW and this occurred on 8 January 2011 at 04:00 AM. The 2011 system minimum

demand was 22.72 % of the 2011 system peak demand. The 24-hour profile for the day of minimum

demand is shown in Figure 7.

Figure 7: OETC System Load on 2011 Minimum Load Day (08/01/2011)

7.2 Demand Forecast

Under clause 3 of Condition 27 of the OETC Transmission and Dispatch Licence it is stated that:

“The Licensee shall, when preparing the Capability Statement …. ensure that the forecasts of electricity

flows and loading on each part of the Transmission System are consistent with the prevailing electricity

demand forecasts prepared and used by the OPWP for the purposes of the Statement of future capacity

requirements required by Condition 5 of the OPWP licence”.

The OPWP demand forecast is based on data supplied to them by the three distribution companies (i.e.

Muscat EDC, Mazoon EC and Majan EC) and includes demand forecasts for the major customers that

are, or will be, directly connected to the OETC transmission system at either 220 kV or 132 kV in their

respective supply areas. The distribution company forecasts are provided in terms of:

a) The growth in major industrial loads

b) The growth in major tourism loads

c) The annual domestic growth

d) The growth in other major loads

The forecasts supplied to OPWP relate to the totals for each distribution company and do not indicate

how this load is allocated to the individual grid supply points. The forecast data provided to OPWP does,

however, include major future connections and the cumulative increase in load over the seven-year period

covered by the OPWP Statement. OPWP has then reviewed this data and taken a view as to the

probability that the individual schemes will proceed and if so, the rate at which their load will develop.

The outcome of this review is presented as the OPWP Demand Forecast in its Seven-Year Statement.

The OPWP Demand Forecast was therefore taken as the starting point for developing the demand forecast

presented in this OETC Capability Statement. The OETC forecast, however, is required to identify the

future demand at individual grid stations at the system peak for each year over the period 2012 to 2016,

since this information is required for the power flow studies.

Analysis of the demand forecast data used by OPWP in developing its Seven-Year Statement (2012 –

2018) identified basic annual percentage rates of 12.23% for the growth in peak demand in the Mazoon

EC, Muscat EDC and Majan DC supply areas. These rates have been applied to the grid station demands

in the respective supply areas as noted by the OETC Load Dispatch Centre at the 2011 system peak (i.e.

18/06/2011, 15:00 hour). The demand associated with major industrial and tourism projects as assessed

by OPWP (with diversity taken into account) was then superimposed on to the steady growth in the basic

demand to produce a basic forecast. Section 5 identified a number of new grid supply points that are

scheduled to come into service to meet the summer peak demands from 2012 onwards. These gird

stations will provide load relief to the more heavily loaded grid stations and in some cases supply new

loads.

The distribution companies’ plans for load transfers from existing grid stations that are heavily loaded to

new grid stations are one of the most important elements of the demand forecast. Table 7 summarises the

load transfers adopted in the studies based on consideration of what is required and what OETC has

considered viable. OETC, however, acknowledges that this aspect of the forecast needs to be improved in

future and believes that it would be helpful if distribution companies were to give greater consideration to

feasible load transfers when planning their distribution networks, and to develop proposals for load

transfers in coordination with OETC. Also, the TSS requirement shall be considered at every GSP and all

new requirement shall be indicated clearly as indicated by in the Grid Code.

8. Transmission System Performance

The transmission system data used in the power system studies to determine the system performance over

the period from 2012 to 2016 is presented in Appendix B of this document.

8.1 Power Flow and Voltage Profiles

The extreme cases of maximum and minimum system demand are used to define the performance of the

OETC transmission system when it is most heavily stressed. From the studies of these extreme conditions

it is possible to identify where the system is strong and has capacity to spare and, conversely, where it is

weak and will need strengthening before new connections could be considered. The peak demand case

identifies where there is a risk of overloading, of operation above firm capacity, or of system voltages

falling below the voltage limits as defined in the Grid Code.

The system data described and presented in Appendix B has been used in a series of load flow studies to

establish the performance of the OETC transmission system at peak demand in each year from 2012 to

2016 inclusive. The studies were undertaken on the basis that all circuits and plant will be available at

system peak in each of the five years and that the system will be developed in accordance with the plans

described in Section 5 of the Statement. The studies also assume that the demand will grow in

accordance with the Demand Forecast, which is consistent with that produced by the OPWP and

distribution companies, and that sufficient generation will be available from both Contracted and Non-

Contracted Generating Plants to meet each annual system peak as indicated in the OPWP latest 7 Year

Statement.

Table 11 shows the summary of the generating plants power assumed to be in service at peak load in each

year of the study from 2012 to 2016. Under peak load conditions it is assumed that capacitive support will

be switched on, i.e. capacitor banks at 33 kV grid stations are properly adjusted to provide required

reactive power and voltage support. In the studies generator terminal voltage and generator-transformer

taps are set to control the voltage on the transmission system at the target busbar to within the allowable

limits.

A second series of load flow studies were undertaken with the transmission system supplying minimum

demand. The minimum demand case identifies where there is a risk of the busbar voltages rising above

the voltage limits defined in the Grid Code and where additional generation has to be operated to absorb

excess reactive power, since there are no reactors connected to the system. At the system minimum

demand, the generation is reduced to a level that provides the necessary margin of reserve capacity that is

consistent with the operational practices adopted by LDC to handle minimum load conditions. Table 12

shows the generating plants assumed to be in service at minimum load in each year of the study. For

2012, real data are listed in the table. These actual values have been obtained from the LDC Daily Report

of the 2012 minimum load which occurred on the 29th of January 2012 at 04:00 am. The total generation

was 1274 MW on that time, which is about 28.86% of expected maximum summer peak (4415MW).

Under minimum load conditions it is assumed that all capacitor banks are switched out and some lightly

loaded transmission lines are off to avoid overvoltage due to excessive capacitive reactive power.

The key results of the load flow and fault level studies on the OETC transmission system are presented in

detail in Appendix C for each year over the period 2012 to 2016. System diagrams are showing the results

of the peak demand. Load flows have also been produced and are available in Appendix C.

The results include the following:

Table C.1 shows the transformer percentage loading of all grid stations at system peak demand.

Table C.2 shows the available spare capacity at each grid station in relation to firm capacity at system

peak demand. It should be noted that although spare MVA capacities are available at some individual

grid stations, there is no guarantee that all can be exploited simultaneously. Lack of available

generation and/or voltage level limits may restrict simultaneous utilization of all spare MVA

capacities.

Table C.3 shows the percentage loading of each overhead line and underground cable in the

transmission system at system peak demand.

Table C.4 shows the voltage profile at each 400 kV, 220 kV, 132 kV and 33 kV bus-bar at maximum

and minimum load.

Table C.5 shows the calculated transmission losses at peak demand.

Tables C.6 and C.7 show the maximum three-phase and single-phase to earth short-circuit fault levels

respectively.

The principal findings from the power system studies are:

Grid Stations Firm Capacities

a) All 400/220 kV grid stations developed during 2014 to 2016 will have firm capacities as

indicated in table C.1. Moreover, these grid stations will have appreciable amount of spare

transformer capacities during the same period and for future needs.

b) The existing eight 220/132 kV grid stations have adequate amounts of spare capacity available

over the period from 2012 to 2016 to cope with growth in demand. The six new 220/132 kV grid

stations that will be commissioned over the period 2013 – 2016 at Jahloot, Al-Hamriyah, Sur,

Izki, Liwa and Mobalah, will substantially increase the amount of grid transformer capacity

connected to the transmission system to facilitate further development of the transmission

system. The 220/33 kV grid station at Blue City consists of two 160 MVA transformers. Azaiba

Coast (Wave Project) 132/11kV grid station will remain within its firm capacity during the

period 2012 to 2016 and beyond this period. This grid station consists of 3x50 MVA

transformers with a firm capacity of 100 MVA.

c) The 132/33 kV grid stations show some constraints in 2012 and 2013. For example, at the

summer peak in 2012, thirteen out of forty seven grid stations will operate above their firm

capacity; this represents about 28% of the total grid stations. None of them will be overloaded.

In 2013 to 2016, a number of 132/33 kV grid stations will be upgraded and new ones are


Page | 63

introduced to remove over firm conditions at some locations. In the period 2014 to 2016 all

132/33 kV grid stations will be operating within their firm capacity.

d) The number of out-of-firm grid stations during the period 2012 to 2016 are:

2012 – 13

2013 – 13

2014 – 0

2015 – 0

2016 – 0

This is shown graphically in Figure 8.

Figure 8: Number of out-of-firm grid stations during 2012-2016.

e) Seven temporary transformers are used in 2012 to mitigate over firm issues and provide

additional capacity at some 132/33 kV grid stations. The number of these temporary

transformers will decrease to five in 2013, three in 2014-2015 and then to only one in 2016.

2013 – 2

2014 – 0

2015 – 0

2016 – 0

Figure 9 shows the reduction in the number of out-of-firm transmission lines during the study

period 2012-2016. There will be no overloaded lines up to the end this period.

g) The single-circuit 132 kV overhead transmission line between Dank and Al-Hail will be

upgraded by Q3-2012 to be compliant with Transmission Security Standard requirements.

h) Implementation of the development projects described in Section 5 and the modest load transfer

programme of Table 7 will restore the full system to compliance with Transmission Security

Standard requirements.

Voltage Issues

i) The voltage at the 400 kV, 220 kV and 132 kV busbars will be maintained within the ±10 %

voltage limit at the extremes of maximum and minimum demand during years 2012-2016.

j) The 33 kV busbar voltages at all grid stations will be maintained within ±6 % of nominal

voltage during these extreme load conditions of maximum and minimum demand, i.e. all 33kV

busbars will be within the acceptable operating range specified in the Grid Code. In fact, the

voltage at all 33 kV busbars is well regulated to be within around 1.0 p.u. in all cases by

exploiting the automatic on-load tap-changer of the 132/33 kV transformers and the capacitor

banks regulators.

k) Figures 10 and 11 show samples of voltage profiles at Airport Heights and MSQ grid stations.

These grid stations have three voltage levels: 220 kV, 132 kV and 33 kV. Although the voltage

at 220 kV and 132 kV busbars can change within the allowable range (depending on the load),

the voltage at the grid supply points is well regulated at almost 33 kV level (1.0 p.u.).

Transmission Losses

l) The calculated active power loss on the transmission system at peak demand over the period

2012 to 2016 ranges between 1.96% and 1.19% of respective total generation as shown in Table

C.5 and Figure 12. The average power loss is about 1.47%, which is well within international

norms.

Figure 12: Transmission power losses at peak demand of the years 2012-2016.

Load Growth

m) The high growth rate of the existing load coupled with major new industrial developments in

Sohar and major tourism projects around the coast to the east and west of Muscat presents a

major challenge to OETC in providing the capacity needed to satisfy demand over the next five

years. Table C.5 shows that the expected peak load increases from 4332 MW in 2012 to 5889

MW in 2016; which amounts to an increase of about 36% during the study period.

Figure 13 shows the expected peak load growth from 2012 to 2016. This peak load includes grid,

industrial, auxiliary and desalination loads, but excludes transmission losses.

Figure 13: Peak load growth over the period 2012-2016.

n) The load flow studies show that the planned 400 kV, 220 kV and 132 kV transmission

developments will add substantial new capacity to the transmission system that will enable the

transmission system as a whole to cope with new demand in compliance with the Transmission

Security Standard. Consequently opportunities for the connection of new load should be

available where spare capacity exists.

8.2 Fault levels

a)- Three-Phase Short Circuit Studies

The maximum 3-Phase and Single-Phase short-circuit fault levels have been determined in accordance

with IEC 60909 and as such the calculation excludes the contribution to fault level from sources at lower

voltages, e.g. from induction motors connected at 11 kV or below. The method is valid and consistent

with that followed by other transmission companies in the absence of data from the distribution

companies for short-circuit back-feeds to the grid station 33 kV busbars. Table C.6 summarises the

results of the 3-phase fault studies over the period 2012-2016:

a) All of the 400 kV busbars have fault levels within the corresponding switchgear ratings.

b) All of the 220 kV busbars have fault levels within the corresponding switchgear ratings.

c) All the 132 kV buses have fault levels within the corresponding switchgear ratings.

d) The 3-phase short-circuit level at all 33 kV busbars does not exceed the switchgear rating.

b)- Single-Phase Short Circuit Studies

Table C.7 summarises the results of maximum single-phase short circuit studies for years 2012 to 2016.

In the years 2012 to 2016 the fault levels across the transmission system are within the corresponding

switchgear short-circuit ratings. During 2012, busbar splitting at Ghubrah in addition to Rusail will be

adopted to reduce fault level to be within existing switchgear ratings. In 2013, splitting will be

implemented at New Ghubrah grid station only. In 2014 and 2016 there will be no need to apply the

splitting technique at any busbars in the system. All busbars will be operating normally without the need

for splitting.

9. Development Opportunities

From the results of the load flow and fault level studies, and from analysis of the magnitude and location

of generation and demand on the transmission system it is possible to give some indication as to where

future generation and demand can be connected to the transmission system without causing or

exacerbating any critical technical issues.

9.1 Review of the generation versus load balance on an area basis

The performance of the transmission system is affected by the transfer of power, both real and reactive,

from one region to another. Large power transfers between regions over long distances increase the

voltage drop across the transmission system. They also increase the power losses and reduce the

efficiency of the system. Ideally if the balance between generation and demand is maintained on a

regional or area basis then power transfers over long distances can be minimised, thus leading to

improvement of the transmission system efficiency and voltage regulation.

Figure 14 shows the connectivity of the OETC transmission in 2016 as it extends over the northern

regions of Oman, a distance of around 500km from Shinas in the North West to JBB Ali in the south-east.

To assess how generation and load is distributed over the transmission system the whole supply area has

been split into seven geographic areas:

a) Muscat

b) Al Batinah South

c) Al Batinah North

d) Al Bureimi

e) Al Dhahirah

f) Al Dakhiliah

g) Al Sharqiyah

Table 13 compares the generation capacity installed in each of the seven areas with the forecast demand

at the grid station at the annual system peak over the period 2012 to 2016.

Muscat area, although geographically the smallest area, is by far the most heavily populated, with the

highest demand (1635.4MW in 2012, rising to 2188.7MW in 2016) and with limited amount of connected

generation (1134MW in 2012, falling to 902MW in 2016). This will result in power deficits of 501MW in

2012 and 1287MW in 2016. Muscat area has two power plants; Ghubrah (447MW in 2012, reducing to

215MW in 2016) and Rusail (687MW during the period 2012-2016). Much of the generation currently

operating at Ghubrah is the most inefficient in the system. The oldest and inefficient generating units at

Ghubrah will be retired in 2013 and 2014, reducing Ghubrah generation to less than 50% of its available

capacity of 2012.

Al Batinah South area covers the coastal strip between Barka on the western outskirts of the Muscat area

and Sohar. This area is likely to develop as Sohar port grows, since the main road link between Muscat

and Sohar runs through it. It also has been chosen for the Blue City Development which is a major

residential and tourist development. Currently, there are three power plants in Al Batiniah South; Barka

Phase-I (434MW), Barka Phase-II (681MW) and Barka Phase-III (495MW). As shown in table 13,the

load in this area rises from 559.6MW in 2012 to 774.2MW in 2016. The power surplus increases from

1051MW in summer peak 2012 to 1078MW in summer peak 2016.

Al Batinah North area is rapidly developing around the new port at Sohar with new industry seeking

connections to the OETC transmission system or the distribution system of the Majan Electricity

Company. Some of the larger industrial customers in the area, such as Sohar Aluminium Company and

Sohar Refinery Company operate their own generating plant and on occasions supply power to the

transmission system on a non-contracted basis. The load in Al Batinah North area significantly increases

from 829.6MW in 2012 to 997MW in 2016, as shown in table 13. Al Batinah North area has two power

plants; Sohar-I (434MW during the period 2012-2016) and Sohar-II (495MW, 745MW, 742MW,

740MW and 739MW in 2012, 2013, 2014, 2015 and 2016 respectively). This will result in power deficits

of 68MW in 2012.The generation surplus in 2013, 2014, 2015 and 2016 will be 217.2MW, 252.4MW,

200.3MW and 176MW respectively.

The transmission system in the Al Bureimi area provides the interconnection with the UAE (Abu Dhabi

Transco) and supplies a number of grid stations that feed the Majan distribution system to supply a

number of small towns and villages in this remote area. Wadi Al Jizzi power plant is the only generation

in Al Bureimi area with power capacity of 245MW in 2012, 2013 and 2014 respectively reducing to

157MW in 2015, and 2016 due to retirement of old inefficient generating units starting from 2012

through 2016. In 2012 the generation surplus is 103.4MW decreasing to 83MW, 72MW in 2013, and

2014 respectively. In 2015 and 2016 the deficiency in generation will be 25.1MW and 45.5MW

respectively.

Al Dhahirah has no local generartion while the load in this area significantly increases from 156.6MW in

2012 to 179.2MW in 2016, as shown in table 13. Power is transmitted from Wadi Al Jizzi generating

plant over about 160km to supply the grid stations at Ibri, Dank and Al Hail. However, the development

plan for the period 2012 – 2016 will see the extension of the 220kV systems from Al Wasit in Bureimi

area to Ibri and this should produce a remarkable improvement in the voltage quality.

Al Dakhiliah area with its provincial load centres is exhibiting a moderate growth and has a local

generating power plant at Manah (273MW) connected to the 132kV transmission system. A connection

between OETC and PDO is available in the area through the 132kV Nizwa-Nahada transmission line.

Power of 60MW maximum can be exchanged between OETC and PDO systems with an annual zero

balance. The deficiency in generation rises from 120.2MW in 2012 to 229.1MW in 2016.

Al Sharqiyah area has provincial load centres that are exhibiting moderate growth up to 2013. However,

a huge industrial load of 300MW is expected to be requested in 2015 by the Sun Metals Company


Page | 73

(ZOOM). With the existing power station at Al-Kamil (297MW) the power deficiency is 145MW in

2012. In the Sur area a private customer (OMIFCO) has installed generation that can provide support

when required again on a non-contracted basis. In 2013 and 2014, Al Sharqiyah area will see a major

generation development by building a power plant at Sur having an early power capacity of 433MW by

summer 2013 and a total of 2000MW by summer 2014. The power surplus in this area will be 254MW,

1788MW, and 1448MW, 1417MW in 2013, 2014, 2015, and 2016 respectively. Compared to other areas

in Oman, Al Sharqiyah area with Sur power plant of 2000MW will have the largest surplus generating

power of 1788MW, 1448MW, and 1417MW in 2014, 2015, and 2016 respectively.

Figures 15 to 21 show graphically the generation and load in each of the seven areas. The significant

differences in generation and load imbalance in areas such as Muscat, Al Batinah South, and Al Sharqiah

necessitate high development and investment in the transmission system to facilitate power transfer

among the different areas in order to supply the growing loads.

10. Derogation

The load flow studies summarised in Appendix C and discussed in Sections 8 and 9 of this Statement

indicate a number of out-of firm grid stations and circuits in the early years of the Statement. In this final

section, we review each station / circuit, which is currently failing to meet the Transmission Security

Standards; we describe the development activities that OETC is undertaking or planning to undertake to

address this non-compliance; and we indicate the expected time by which, in each instance, full

Transmission Security Standards compliance should be achieved.

It should be noted that the Transmission Security Standard on the transmission system would change in

future as demand on the system increases and as the system configuration changes. It is possible that

further non-compliances might arise in the future until the overall system becomes substantially more

robust through interconnection. OETC will keep this situation under review, and the non-compliance

status will be updated in the 2013 Capability Statement.

As indicated in sections 8, 9, and summarized in tables 15 and 16 (A &B), there are some grid stations

and overhead lines, which do not comply with the Transmission Security Standard. Therefore, it will be

necessary for a further location and duration specific derogations to be put in place by the Authority for

each of the out of firm circuits noted in table 15, and for each of the stations which do not comply with

the Transmission Security Standard at peak and maintenance time noted in table 16 (A) and 16 (B)

respectively.

The following points should be noted:

1- The loading values show in tables C1 and C3 (Appendix C), are those at the peak load conditions. The

system peak lasts only for a period of less than one hour in one day during the relevant year. (For

example, refer to Figure 6 of 2011daily load curve peak day).

2- According to the most recent OPWP data, there are two forecast cases: (i) expected case, and (ii) high

case. The difference between the high and expected case in 2012 is 147 at the peak. This difference

increases in the subsequent years and reaches 1078 MW in 2016, indicating uncertainty in the forecast

over the coming years especially with regards to new industrial loads. OETC supports OPWP’s view

that the likelihood of the high case demands being realized is heavily dependent on the rate of recovery

of the current global economic and financial conditions. OETC intends to monitor closely, in

coordination with OPWP, the situation in order to assess the probability associated with the high case

projection.

3- It is not prudent to invest in uncertain expansion. OETC will, of course, initiate new projects as new

demand becomes more certain. Therefore, in Tables 15 and 16 we concentrate on covering the

conditions at the peak in 2012.

4- The modelling reflects all load transfer schemes that have been formally accepted by the relevant

distribution company and included in their load forecasts. In addition, the modelling includes certain

load transfer schemes, which are not yet confirmed by the distribution company concerned, but which


Page | 88

in the view of OETC are technically feasible and where no technical impediment to implementation

exists.

OETC has adopted a three-fold approach to addressing these out of firm situations:

1) Reinforcement plans: strategic upgrading to add new circuits and/or to increase the capacity of

grid stations within a minimum of two to five years. This will not just solve the problem; but it

will also strengthen the transmission system for future development. This type of solution can

only be applied as a longer term solution because of the time taken to implement. Reinforcement

is the most robust long term solution for secure system development, but may not necessarily be

the least cost solution to address the immediate out of firm conditions on the network.

2) Installing third transformers at heavily loaded grid stations, such as MSQ, Mawalleh, Wadi Kabir,

Barka Main, Sumail, Ghubrah and Izki. These will provide a temporary solution to the out-of-

firm problems at the heavily loaded grid stations until a permanent solution is put in place.

3) Load Transfer: through agreement with distribution companies, load can be transferred from

heavily loaded grid stations to more lightly loaded grid stations over the next three years. This

would reduce the loading issues and balance the system during peak time. This is a mid-term

solution which could be implemented with the cooperation of distribution companies in certain

cases. Given the uncertainty of mid-term load forecasts in Oman at present, this is in some

circumstances the most appropriate and economic action to address out of firm conditions on the

network.

Tables 15 and 16 (A) indicate a number of locations on the system where, at present, the out of firm

condition of certain circuits or transformers is shown to exist. Table 16 (B) shows the grid stations which

are classified as group E (>100 MW) as per the Transmission Security Standard. Some of them will not

comply with Transmission Security Standard (Second Outage) at 2012 maintenance period.

Appendix A: Review of Future Developments

A.1 Summary of Projects to be completed between 2012-2016 Peak Demand

The OETC transmission network is undergoing widespread and rapid development due to the expansion

requirements of distribution companies, large private customers, and new generation requirements based

on the yearly demand growth and further reinforcements on the transmission network to ensure the

security, quality and reliability of the system.

An important change to the Omani electricity sector is the new interconnector between Oman and the

UAE (TRANSCO Abu Dhabi). The 220kV interconnector has been energized. A new 400 kV connection

between Oman and UAE has been proposed by TRANSCO Abu Dhabi and is currently under consultancy

stage. The line will be connected between Mahadah in Oman and Swaihan in UAE. There are a

significant number of projects required to meet the annual peak demands over the period of this Statement

(2012-2016). These projects are considered below under the following categories:

Projects of 2012 peak demand.

Projects that are at design stage.

Projects that are at the tender evaluation stage prior to appointment of the preferred

EPC Contractor.

Projects for future developments that represent the least cost options to address

problems with system growth, voltage profile, non-complince with the Transmission

Security Standard by transmission system reinforcement.

The entire programme of ongoing and future projects which are planned for implementation over the

period 2012 to 2016 are listed and described below. It should be noted that the project numbers referred

in this Appendix are identical to those in Table 1 of the Executive Summary, and it should also be noted

that not all of the projects described have full authorisation at this time and to be supported by pre

investment appraisals document to approve and to select the proper option for each project.

A.2 Projects expected to be completed to meet the 2012 peak demand

Project #1: Adding fourth transformer 125MVA at Bousher grid station

A fourth transformer was added within Bousher grid station as new group demand connected to the third

transformer as Bousher-B. It will be operated separately from the existing transformers at 33kV voltage

level by shifting part of the existing load from Bousher-A to Bousher-B. The two groups will be

connected on one bus bar at132kV voltage level. This project was energised in Q4’2011. A transfer

switch will be installed between the 33kV Bousher-A and Bousher-B busbars to facilitate compliance

with the TSSS during maintenance periode.

Project #2: 132/33 kV Grid Supply Point at Yitti

The new Yitti tourist resort in the Muscat Governorate will be supplied from a new 132/33kV, 2 x

125 MVA transformer grid station at Yitti, which in turn will be fed from a new 132 kV bus-bar

arrangement installed at Jahloot 132/33 kV grid station via a 132 kV double circuit line. The new GSP

will also supply the existing Yitti load, which is currently supplied from Jahloot at 33 kV. The overhead

line has been designed to 220kV standard, but operated at 132kV. The 220 kV design makes provision

for a possible future upgrade of the supply to 220 kV in the event that demand in the Yitti area grows to

the extent that a higher transmission voltage is required to supply the area. This project is expected to be

in service by Q2 2012.

Project #3: New 132/33 kV grid supply point at Qurum

The new 132/33 kV, 2 x 125 MVA transformer grid station is constructed to supply new developments in

Ras Al Hamra and Qurum and to receive load transfers from MSQ and Wadi Adai grid stations. This

project is expected to be in service by Q2 2012.

Project #4: New 132/33 kV grid supply point at Muttrah

A new 132/33 kV 2 x 125 MVA transformer grid station is constructed at Muttrah to take load transfers

from Wadi Kabir and Al Falaj 132/33 kV grid stations. The new grid station will be supplied directly

from Qurum 132/33 kV grid station by construction of a new 132 kV double circuit line. The Muttrah

area is currently supplied from the existing Al Falaj and Wadi Kabir grid stations, which were both

operating above firm capacity at 2011 peak load conditions. The new grid station at Muttrah is preferred

to the alternative of reinforcement of the existing Al Falaj and Wadi Kabir grid stations. This project is

expected to be in service by Q2 2012.

Project #5: Upgrade of the 132 kV double circuit lines between Al Wasit and Bureimi and Dank

Al Hail

Part-1: New 132kV double circuits line between Mahadah and Bureimi grid stations (30.73km O/H

and 5.47km 2500mm2 underground cable)

This project was previously divided into two projects Mahadah-Bureimi and Dank- Al Hail. However,

due to the urgency of the requirement of the Dank- Al Hail, it is merged in one project. The existing

132 kV, 33 km double circuit line between Mahadah (Al Wasit) and Bureimi was operating over-firm at

2011 peak load conditions. And to increase the capacity of the single ‘Elm’ conductor per phase to be

replaced with twin ‘Yew’ conductor. Approximately 5.47 km of the route will be by underground cable

(2500mm2). This project is expected to be in service by Q2 2012.

Project #6: New 220/33 kV grid supply point at Blue City

The electricity supply to the new Blue City development in the South Batinah region will be fed from a

new 220/33 kV grid supply point connected between the MIS and Filayj grid stations by routing the

220kV MIS – Filayj double circuit connection through the new grid station in a line-in-line-out (LILO)

arrangement. The diversion will require two 220 kV double circuit overhead lines over part of the route

and four 220 kV 2500mm2 cable circuits over the last 6 km of the route as it reaches the Blue City grid


Page | 94

supply point. The project will supply the Blue City project as requested by Mazoon Electricity Company

and for surrounding area. This project has been already energized.

Project #7: Adding third transformer 125MVA at Barka Main

A third 132/33 kV 125 MVA transformer will be installed at Barka Main to shift around 50MW from the

existing two transformers to relief loading on the existing transformers. This project is expected to be in

service by Q2 2012.

Project #8: Upgrade of the 132/33 kV grid station at Seeb Main

The existing grid station with an installed transformer capacity of 2 x 63 MVA was loaded above its firm

capacity during 2011 peak load conditions. The proposed scheme is to construct new 2 x 125 MVA

transformers. This project is currently under testing and commissioning stage. This project is expected to

be in service by Q2 2012.

Project #9: Upgrading of Dhahirah system from 132kV to 220kV (Part 1)

This project is designed to be as 220kV system to connect Al Dhahirah area with 220kV system by

adding 2x 500MVA transformers at Ibri grid station, 145km OHL of 220kV between Ibri - Mahadah and

50km of 132kV OHL between Dank-Ibri . This project will support the area by the reactive power to

improve the voltage. The project consists of upgrading of Ibri to 2x 125MVA as the station is currently

out of firm. This project will support the voltage in the area and it will meet the Transmission Security

Standard requirement for all 132kV lines. The existing wooden-pole lines will remain and the link

between Wadi Sa’a and Dank will be opened and used for emergency only. In addition, this project will

support the interconnection with UAE and the GCC systems. The project is expected to be in service by

Q2 2012.

Project #10: New 220kV grid station at Sohar for the new Sohar II IPP

This project will be constructed to connect the new IPP power at Sohar by construction of 220kV grid

station connected to the SIS grid station with 36.9km of 220kV over headlines and 2.6km of 2500mm2

underground cables. The 220kV GIS ia already energized.This project is expected to becompletely in

service by Q2 2012.

Project #11: New 132/33kV GSP at Quriyat area

The demand at Quriyat is currently supplied at 33 kV from Jahloot, a distance of 50km, which causes

reduced voltage during peak load conditions. The planned 132/33 kV 2 x 125 MVA transformer grid

station at Quriyat supplied from Jahloot via a 132 kV double circuit line will address the voltage problems

around Quriyat area. This project is expected to be in service by Q2 2012.

Project #12: Re-connecting of 132kV lines within Muscat area

This project is divided into two parts.

Part one:

Part one is to connect the fourth circuit of Ghubrah-MSQ to be connected to Bousher. The circuit will be

as Ghubrah- Bousher –MSQ. By doing this connection Bousher will be secured by another supply source

from MSQ. The 132kV GIS of Bousher-Rusail will be used for connecting this circuit as LILO. The


Page | 95

process of this work is included in the underground project. This part is expected to be in service by Q2

2012.

Part two:

The objective of this part is to supply Seeb Main grid station directly from Airport Heights grid station

instead of suppling it from Mawalleh grid station. This will be accomplished by constructing new

underground double circuits from Airport Heights to Mawalleh end of the OHL between Mawalleh and

Seeb Main grid stations. This will reduce loading of the currently out of firm Rusail-Mawalleh line and

make it compliance with the TSSS. Also this connection will help in using of the 220kV lines between

Filaj and Airport Heights in efficient way, considering Ghubrah will feed the total required demand to

MSQ which is the nearest grid to the load. This project will also reduce the cost of the proposed

underground cable project for Rusail- Bousher 132kV line. By doing this project the other part of the

Bousher-Rusail that is passing close to Mawalleh will be dismantled. This project is expected to be in

service by Q2 2012.

Project #13: New Misfah 220kV interconnection grid station

This project will be constructed to connect the new IPP power at Barka to Misfah. This grid will be

connected through 58.2km of 220kV overhead lines and 10.2km of 2500mm2 cables. MSQ-Airport

220kV line will be connected to Misfah grid station for flexibility and reliability of the 220kV system

between Sur and Muscat Systems. This project is expected to be in service by Q2 2012.


Project #14: Upgrade of the 132 kV double circuit line between Al Wasit and Bureimi and Dank

Al Hail

Part-2: New 132kV double circuits line between Dank and Al Hail grid stations (52.6km O/H).

This project is part of project no.5 above. This part of the project is upgrading of the Dank Al Hail 132kV

lines from wooden pole to steel tower double circuit line. The current single circuit wooden pole is not

compliant with the Transmission Security Standard requirements. Al Hail area also suffers the worst

voltage conditions on the OETC transmission system because of its remote location on the system and its

single circuit connection. Upgrading the connection to a double circuit is considered a high priority

scheme and is required at the earliest date. This project is expected to be in service by Q3 2012.

Project #15: New 220/132kV grid station at Sur

Upgrading of Sur to 220kV system by adding 2 x 500MVA transformers that will allow the flow of

power from Sur power plant to Sur area (Sur and Ayjah grid stations) and Sharqiah grid stations

(AlKamil, JBB Ali, Mudhaibi and Mudharib) from Sur power plant grid station. This project will also

support the reactive power for Sharqiah area. This project is expected to be in service by Q3 2012.


Page | 96

Project #16: Upgrading Jahloot to 220kV system

Upgrading of Jahloot to 220kV system by adding 2 x 500MVA transformers that will be connected to

Misfah 220kV grid station by using 220kV OHL (54.9km) and to Sur grid 130km (desined 400kV

operated initially at 220kV). Jahloot system will be also connected to Hamryah 220kV which will be

connected to Muscat area grid stations (Wadi Adai, Wadi Al Kabir, Muttrah, Al Falaj and Qurum)

through 132kV system network within the area. Upgrading of Jahloot grid station to 220/132 kV system

will eliminate voltage problem and strengthen the supply in Jahloot area. This project is expected to be in

service by Q4 2012.

Project #17: Upgrading Izki grid station

The objective of this project is to upgrade the transformers at Izki grid station from 2 x 40MVA to 2 x

125MVA to address both overloading and voltage issues. This project is expected to be service by Q4

2012.

Project #18: Upgrade 132/33 kV Mudhaibi grid station

The objective of this project is to upgrade the two transformers of Mudhaibi grid station from 63MVA to

125MVA. The project will have an impact on reducing the overloading on the grid station and also will

support the voltage in the area. The project is expected to be in service by Q4 2012.

Project #19: Upgrade of Rustaq grid station

The objective of this is to upgrade Rustaq grid station from 2x63MVA to 3x125MVA transformers. This

will address the current overloading and voltages problems within the area. The 63MVA transformers

will be used for upgrading Dank grid station. This project is expected to be in service by Q4 2012.

Project #20: Upgrading of Dhahirah system from 132kV to 220kV (Part 2)

The project consists of upgrading of Dank to 2x 63MVA transformers (these transformers are released

from upgrading Rustaq grid station). This station is currently out of firm. This project will support the

voltage in the area and it will meet the Transmission Security Standard requirement. The existing wooden

lines will remain and the link between Wadi Sa’a and Dank will be opened and used for emergency only.

This project would reinforce the transmission system voltage and further load demand in the area. This


Project #21: New 220kV grid station at Al Hamriyah (Wadi Adai-2) area

Appendix B: Transmission System Data

B.1 Substations Loads and Capacitor data.

The grid station real and reactive power load at system peak demand for the period 2012 to 2016 and the

respective reactive power support from capacitor banks connected at the grid station 33 kV busbars is

shown in Table B.1.1 This data was used in the power flow studies of system peak demand presented in

Section 8 of this Capability Statement.

B.2 Overhead Line Circuit Capacities and Parameters.

The continuous thermal rating of a circuit is the maximum power flow that can be carried by that circuit

on a continuous basis. The thermal rating of an overhead line is the power flow that can be carried by that

line without infringing the statutory clearances and causing a risk to public safety and to the line itself.

The thermal rating of an underground cable, however, is the maximum power flow that the cable can

carry without either causing the cable to fail or to effectively reduce its projected lifespan through a

deterioration of the cable insulation.

Although the thermal rating of an overhead line is affected by climatic conditions, for the purpose of

assessing spare capacity on the transmission system the key climatic condition that limits the circuit rating

is the summer rating when the temperature is at its highest and the solar radiation is at its peak. This also

corresponds to when the electricity demand is at or near to its peak.

The circuit data presented in Table B.2 for the first year of the Statement period (2012) comprises the

voltage, resistance, reactance, susceptance and thermal rating of the line and cable circuits. It also shows

the circuit length and the type of overhead conductor or underground cable for each circuit.

Table B.3 shows the changes to the circuit data required in each of the other four years covered by the

Statement.

B.3 Transformer data

The data used to model the grid supply point transformers in the power flow studies of the 2012 summer

peak demand condition is listed in Table B.4. The data comprises the transformer voltage ratio, the

resistance and reactance, the tap range and step size. Table B.5 lists changes to the transformer data for

the remaining four years of the Statement.

1 The 33 kV busbars at the grid supply points and the capacitors connected to them are owned and operated by the distribution companies.
