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 2011 to 2015.
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 the 400 kV, 220 kV and
132 kV transmission system, 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 seven to thirteen before the summer peak of 2015, 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-two in service
at the beginning of 2011 to fifty six by the summer peak of 2015. 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 2011 the company will introduce direct voltage transformation from 220kV to 33kV on the
transmission system with respective 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 Al-Wasit in Mahadah
was completed will 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 build a 220 kV line between Mahadah to Ibri to support the voltage
and meet the expected load growth.
In addition, OETC will introduce the first 400kV connection between Jahloot grid station and Sur power station.
First, this line will be operated at 220kV in 2012 and then will be operated as 400kV when required.
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 Oman Power and Water Procurement
Company (OPWP) as per its 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). The deadline was 1st January 2011. Any information received after the 1st of January 2011, will be
included in the next Five-Year Annul Transmission Capability Statement (2012-2016).

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 9.3 % over the period 2011 –2015 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 a potential shortfall in generation capacity at system
peak in 2011. To meet the shortfall, it is assumed that power will be imported from direct customer
generation and installation of temporary diesel generation at different locations (300 MW in 2011). In
addition the new generating capacity from Barka Phase-3 (750MW), Sohar Phase-2 (750MW) and Sur
IPP (2000MW) will be required to meet future growth and avoid a further shortfall in generating capacity.
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 53 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 220 kV transmission systems to well beyond 2015.
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 2010, the 132 kV bus bars were split at Rusail, but practical difficulties at Ghubrah prevented its
implementation and the action to split the 132 kV bus bars there has been postponed to be implemented in
2011. Until then operating restrictions are being applied to avoid performing any works near switchgear
Five-Year Annual Transmission Capability Statement (2011 - 2015)
Page | 21
at Ghubrah Power Station. Given the ongoing operational difficulties associated with splitting the
Ghubrah busbar and the potential reliability issues with Ghubrah generation alternative network splitting
options are being considered to temporarily solve the short circuit problem at zero cost.
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. In the case of Al Hail, the 132/33 kV
grid station is currently supplied via a single circuit line from Dank, but by the Q3 2011 this will be
upgraded to a double circuit connection.
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.
Consequently, OETC has written to the distribution companies to request that they add more capacitor
banks at the distribution voltage level to operate within the recommended power factor as an additional
measure for improving system efficiency for the 2011 system peak.
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.

2. Introduction
2.1 Licence conditions, Codes and Standards
This Transmission System Five-Year Capability Statement covers the period 2011 – 2015 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 2010-2014 Statement

2.3 Improvements in the preparation of the Statement
Since the issue of the Transmission System Capability Statement for 2010 – 2014 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 OPWP and distribution
companies which should make for a more accurate forecast.
Five-Year Annual Transmission Capability Statement (2011 - 2015)
Page | 25
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.

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.
Five-Year Annual Transmission Capability Statement (2011 - 2015)
Page | 27
b) The voltage on the 66 kV, 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.

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%)
In determining the thermal rating of an overhead line conductor “still air” (i.e. a wind speed of 0.5km per
hour) is used as this has the least cooling effect on the conductor. 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.
4.3 Oman Electrical Standard OES 27
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.
4.4 Oman Electrical Standard OES 32
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 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 Housing, Electricity and Water
(MHEW) 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:
835 circuit-km of 220 kV overhead transmission line
2969.86 circuit-km of 132 kV overhead transmission line
12 circuit-km of 220 kV underground cable
63.798 circuit-km of 132 kV underground cable
6630 MVA of 220/132 kV transformer capacity
9239 MVA of 132/33 kV transformer capacity
150 MVA of 132/11 kV transformer capacity
Two 220 kV interconnection grid stations
Two 220/132 kV grid stations
Five 220/132/33 kV grid stations
Thirty seven 132/33 kV grid stations
One 132/11 kV grid station
The transmission system is interconnected at 220 kV from Al Wasit grid station in Mahadah 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 will be fully
energised and brought into service when the Inter-Governmental agreement is signed.
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.
Five-Year Annual Transmission Capability Statement (2011 - 2015)
Page | 30
The transmission system is supplied with electricity generated from eight gas-based power stations
located at Ghubrah, Rusail, Wadi Jizzi, Manah, Al Kamil, Barka AES & Barka SMN and Sohar. In
addition the transmission system may be supplied from direct customers, such as Sohar Aluminium 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, 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
viii. VALE
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 2014.
The New Muscat International Airport (Ministry of Transport) will be connected to
Airport Heights grid station in 2012.
Five-Year Annual Transmission Capability Statement (2011 - 2015)

In 2010, the system gross peak demand was 3614MW which occurred at 15:00 hours on 1 June, an
increase of 1.9 % on the 2009 peak demand. This small load growth was due to unexpected change of
weather as the cyclone PHET hit Al Sharqiyah region and some rains in other parts of Oman. During
2010, the Electric Energy Delivered (EED) to the MIS system from connected generating plants was
16,855.131 GWh, whilst that exported from the MIS to the distribution companies was 16,357.501 GWh
resulting in transmission system energy losses of 497.630 GWh , which equates to a transmission system
energy loss of 2.95% in average.
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 2011 peak demand
A geo-schematic diagram of the existing transmission system in 2011 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 2010– 2014
Capability Statement was published and that the new works were being energised so that they were
available to meet the peak demand in summer 2011. 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 2011 system demand include a new grid station at Wadi Sa’a, Al Misfah,
Nakhal, Yitti, Qurum and Muttrah. Also, construction of 220 kV double circuits between SIS (Seh Al
Makarim) and Mahadah (Al Wasit) grid stations and 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 was completed. A number of grid stations cannot maintain the Transmission
Security Standard requirement and additional 125 MVA third transformer capacity is being provided to
meet the 2011 summer peak at MSQ, Mawalleh and Wadi Kabir grid stations.
5.2.2 Projects expected to be completed to meet the 2012 peak demand
Figure 2 shows in geo-schematic form the system development plan to meet the 2012 peak demand. The
new projects scheduled for completion in time to meet the summer peak demand in 2012 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 2012 system demand include a new grid station at Blue City, a new grid
station at Quriyat, third 125 MVA transformer at 132/33 kV Barka Main grid station, upgrading Seeb
Main 132/33 kV grid station to 125 MVA transformers, fourth 125 MVA transformer at the 132/33 kV
Bousher grid station and replacement of the 132 kV wooden pole O/H lines with steel tower between
Dank and Al Hail grid stations. 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 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
Five-Year Annual Transmission Capability Statement (2011 - 2015)
Page | 32
reducing power losses. Also, construction of new 132 kV line between Ibri and Dank and upgrading Ibri
transformers to 125 MVA and Dank transformers to 63 MVA.
The main investment to meet the 2012 peak is in the extension of the 220 kV transmission systems from
Barka IPP to Misfah grid station. The 220 kV transmission systems will be extended from Misfah to
Jahloot and on to Al Hamryah 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 2012 are the new 220/132 kV, 2 x
500 MVA grid stations to be established at Sur, Al Hamryah and Jahloot. The new IPPs at Barka and
Sohar will be connected to the 220 kV transmission system through new 220 kV GIS substations at Barka
(Barka-2) and Sohar (SPS-2). SPS-2 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 circuit. Further
upgrading projects are also required at Mudhaibi, Izki, Rustaq and Shinas grid stations.
5.2.3 Projects expected to be completed to meet the 2013 peak demand
Figure 3 shows in geo-schematic form the system development plan to meet the 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 upgrading of the transformers to 125
MVA at Sumail grid station and upgrading of 132 kV line between Wadi Adai and Wadi Kabir grid
station. Other projects that are required to meet the 2013 peak are the construction of new 132/33 kV grid
stations at Al Amerat, Ghala, Madinat Nizwa, Madinat Barka, Al-Kamil, Samad A’Shan, Ayjah and
Bureimi-B. Other projects that are required to meet the 2013 peak are the construction of new 132/33 kV
grid station at Al Ghubrah, new 132/33 kV grid station at Mabellah and replacing of Mawalleh Seeb Main
overhead line to underground cables. Also, upgrading of Al Hail transformers to 125 MVA, adding fourth
125 MVA transformer at Mawalleh grid station, adding third and fourth 125 MVA transformers at Sohar
grid station and linking Al Falaj, Muttrah and Wadi Kabir grid stations by one circuit underground cables.
5.2.4 Projects expected to be completed in time to meet the 2014 peak demand
Figure 4 shows in geo-schematic form the system development plan to meet the 2014 peak demand. One
of the major projects expected to be connected to the transmission system by summer 2014 is the
construction of new grid station at sohar special economic zone. This grid will be constructed inside Liwa
grid station and new 220/132 kV, 2 x 500 MVA transformers will be installed in the same grid to supply
the new industrial load. The other major project planned for completion before summer 2014 is the new
220/132 kV, 2 x 500 MVA grid stations to be established at Izki which will be connected to Sur grid
station. Also, 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, 4 x 500 MVA grid 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). Also, new 132/33 kV grid stations at Al Khadra will be constructed.

5.2.5 Projects expected to be completed in time to meet the 2015 peak demand
Figure 5 shows in geo-schematic form the system arrangement to meet the 2015 peak demand. A project
expected to be connected to the transmission system by summer 2015 is construction of new 132/33 kV
grid station at Sumail area to supply the Sumail industrial load.
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 2011-2015 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 is currently supplied by eight gas-based power stations:
• Ghubrah and Rusail in Muscat region (Muscat Electricity Distribution Company supply area).
• Barka AES and Barka SMN in Al Batinah South region, Manah in Al Dakhilya region and Al Kamil in Al
Sharqiyah region (Mazoon Electricity Company supply area).
• Sohar I in North Al Batinah region and Wadi Jizzi in Al Bureimi region (Majan Electricity Company supply area).
The eight 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 four steam turbines of various
ratings. The net generation capacity is approximately 468.5 MW.
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 MW to 96 MW. The units
were installed progressively between 1984 and 2000. The net generation capacity of the power station is
approximately 686.9 MW.
c) Wadi Jizzi Power Station
Wadi Jizzi Power Station comprises ten Frame 6B gas turbines (with gross site ratings in the range of 27.6 -
30.2 MW) and one Frame 5P gas turbine (17.8 MW gross site rating) where are all operating in open cycle. The
units were installed progressively from 1982 and the net generation capacity is approximately 290.2 MW.
d) Manah Power Station
Manah Power Station is owned by the United Power Company and when commissioned in 1996 was the first
Independent Power Project (IPP) to be built in Oman. The station comprises three GE PG6541B gas turbines
(each site rated at 26.7 MW) and two GE PG9171E gas turbines (site ratings of 95 MW and 97 MW respectively).
The net generation capacity is approximately 279.3 MW.
e) Al Kamil Power Station
Al Kamil Power Station is another IPP and was commissioned in 2002. The station comprises three GE PG9171E
gas turbines (site rating 94 MW) operating in open cycle and the net generation capacity is approximately
296.8 MW.

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 GT1-3 (51 MW) and GT4-9 (100.5 MW). In
addition, ST4 (39.2 MW), GT10 (27.1 MW) and GT11 (26.1 MW) will be retired in 2014.
b) Wadi Jizzi Power Station
In 2012, it is planned to retire the existing units GT6-7 (31.3 MW) and GT3 (17.6 MW). In addition,
GT4 (30.8 MW), GT5 (31.3 MW) and GT8 (30.2) will be retired in 2015.
6.3 Planned future generation (2011 – 2015)
There are three main generation developments planned for the period 2011 to 2015:
a) IPP at Barka (phase 3) Power Station (750MW)
Due to the expected future shortfall in generation, OPWP has instigated planning work for a third power
plant at Barka area. This independent power plant (IPP) will be designed to have a generating capacity of
750MW (2 x 245MW GTs in 2012 and one 260MW ST in 2013).
b) IPP at Sohar (phase 2) Power Station (750MW)
OPWP has also taken action to instigate planning work for a second power plant at Sohar area where
there is already a large industrial demand and projections of future load growth show that additional
power generation is required in the area. The new IPP will be introduced in two stages, like Barka – 3.
This independent power plant (IPP) will be designed to have a generating capacity of 750MW (2 x
245MW GTs in 2012 and one 260MW ST in 2013).
c) Sur IPP (2000MW)
Due to the expected future shortfall in generation OPWP has instigated planning work for a power plant
at Sur area. This power plant (IPP) will be designed to have a generating capacity of 2000MW (500MW
in 2013 and 1500MW in 2014).
Table 3 summarises the net capacity of the additional future generating plant over the period 2011 to 2015
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 2015 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 280 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. However, the interconnection has not to date come into
service. The interconnection is via a 220 kV double circuit overhead transmission line with twin
“Araucaria” (2 x 800mm2) AAAC conductors per phase, with a conductor thermal rating of 2000 Amps
(i.e. 762 MVA per circuit).
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.
Five-Year Annual Transmission Capability Statement (2011 - 2015)
Page | 46
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
overhead line with a single “Elm” (200mm2 AAC) conductor per phase and a circuit rating of 357 Amp
(i.e. 82 MVA). 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, namely the 220 MW steam turbine generators at
Barka. This figure might be reviewed by OPWP and OETC after introducing the new IPPs at Barka,
Sohar and Sur.

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 2010 system peak demand (i.e. 01/06/2010). The 2010 system peak demand of 3614 MW was
recorded at 15:00 hours by the OETC Load Dispatch Centre. The historic growth in system peak demand
over the period (2003-2010) 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 2010 the system minimum
demand was 766 MW and this occurred on 16 January 2010 at 03:00 AM. The 2010 system minimum
demand was 21.19 % of the 2010 system peak demand. The 24-hour profile for the day of minimum
demand is shown in Figure 7.

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 2011 to 2015,
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 (2010 –
2016) identified basic annual percentage rates of 7 and 8 % respectively 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 2010
system peak (i.e. 01/06/2010, 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 2011 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.

8. Transmission System Performance
The transmission system data used in the power system studies to determine the system performance over
the period from 2011 to 2015 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 2011 to
2015 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 generating plants power assumed to be in service at peak load in each year of the
study from 2011 to 2015. Under peak load conditions it is assumed that capacitive support will be fully
switched on, i.e. capacitor banks at 33 kV grid stations are raised to provide reactive power and voltage
support. In the studies the 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
2011, real data are listed in the table. These actual values have been obtained from the LDC Daily Report
of the 2011 minimum load which occurred on the 8th of January 2011 at 04:00 am. The total generation
was 909MW on that time, which is about 22.25% of expected maximum summer peak (4085MW).
Under minimum load conditions it is assumed that all capacitor banks will be switched out.

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 2011 to 2015. 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:
Out of firm conditions
a) The seven existing 220/132 kV grid stations have adequate amounts of spare capacity available
over the period from 2011 to 2015 to cope with growth in demand. The six new 220/132 kV grid
stations that will be commissioned over the period 2012 – 2014 at Al-Hamriyah, Jahloot, Ibri,
Izki, Liwa and Sur, will substantially increase the amount of grid transformer capacity connected
to the transmission system to facilitate further development of the transmission system. The new
220/33 kV grid station at Blue City will be commissioned in Q3 2011, with two 160 MVA
transformers. The additional capacity will enable load transfers between grid stations to
eliminate over-firm operation. The 400/220kV interconnection grid stations at Sur and Jahloot
will be available by 2014 system peak subject to completion of 2000 MW power plant at Sur
area.
Azaiba Coast (Wave Project) 132/11kV grid station will remain within its firm capacity during
the period 2011 to 2015 and beyond this period. This grid station consists of 3x50MVA
transformers with a firm capacity of 100MVA.
b) The 132/33 kV grid stations show some constraints in 2011 and 2012. For example, at the
summer peak in 2011, 15 out of forty two grid stations are operating above their firm capacity;
this represents 36% of the total grid stations. None of them will be overloaded. In 2012, a
number of 132/33 kV grid stations will be upgraded and new ones are introduced to remove
Five-Year Annual Transmission Capability Statement (2011 - 2015)
Page | 62
over firm conditions at some locations. The number of out of firm grid stations will reduce to
five, which is about 11% of the total 45 grid stations operating in the system in summer peak
2012. The number of out of firm grid stations will significantly decrease to 2 out of total 56 grid
stations in 2013. In 2014 and 2015 all 132/33 kV grid stations will be operating within their firm
capacity.
c) Seven temporary transformers are used in 2011 to mitigate over firm issue and provide
additional capacity at some 132/33 kV grid stations. The number of these temporary transformer
will decrease to six in 2012 and then to three in 2013, 2014 and 2015.
d) The number of out-of-firm grid stations during the period 2011 to 2015 are:
• 2011 – 15
• 2012 – 5
• 2013 – 2
• 2014 – 0
• 2015 – 0
This is shown graphically in Figure 8.

e) All 220 kV transmission lines are compliant with the Transmission Security Standard.
f) The number of 132 kV double circuit lines operating above firm capacity over the period 2011-
2015 will be as follows:
• 2011 – 8
• 2012 – 2
• 2013 – 1
• 2014 – 0
• 2015 – 0
Figure 9 shows the reduction in the number of out-of-firm double circuit lines during the study
period 2011-2015. There will be no overloaded lines towards the end this period.

g) The single-circuit 132 kV overhead transmission line between Dank and Al-Hail will be
upgraded by Q3-2011 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 before the end of the Statement period.

Voltage Issues
i) The voltage at the 220 kV and 132 kV busbars will be maintained within the ±10 % voltage limit
at the extremes of maximum and minimum demand during years 2011-2015.
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: 220kV, 132kV and 33kV. Although the voltage at
220kV and 132kV busbars can change within the allowable range (depending on the load), the
voltage at the grid supply points is well regulated at almost 33kV level (1.0 p.u.).

Transmission Losses
l) The calculated active power loss on the transmission system at peak demand over the period
2011 to 2015 ranges between 1.3% and 1.5% of respective total generation as shown in Table
C.5 and Figure 10. The average power loss is about 1.398%, which is well within international
norms.
Figure 12: Transmission power losses at peak demand of the years 2011-2015.
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 4005MW in 2011 to
5651MW in 2015; which amounts to an increase of about 41.1% during the study period.
Figure 11 shows the expected peak load growth from 2011 to 2015. This peak load includes
grid, industrial, auxiliary and desalination loads, but excludes transmission losses.

Figure 13: Peak load growth over the period 2011-2015.
n) The load flow studies show that the planned 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 2011-2015:
a) All of the 220 kV busbars have fault levels within the corresponding switchgear ratings.
b) All the 132 kV buses have fault levels within the corresponding switchgear ratings.
c) 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 2011 to 2015.
In the years 2011 to 2015 the fault levels across the transmission system are within the corresponding
switchgear short-circuit ratings. During 2011-2012 busbar splitting at Ghubrah in addition to Rusail will
be adopted to reduce fault level to be within existing switchgear ratings. In 2013 splitting at Ghubrah will
also be implemented. In 2014 and 2015 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 2015 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 2011 to 2015.
Muscat area, although geographically the smallest area, is by far the most heavily populated, with the
highest demand (1610MW in 2011, rising to 2028MW in 2015) and with limited amount of connected
generation (1155MW in 2011, falling to 919MW in 2015). This will result in power deficits of 454MW in
2011 and 1109MW in 2015. Muscat area has two power plants; Ghubrah (468.5MW in 2011, reducing to
232MW in 2015) and Rusail (687MW during the period 2011-2015). Much of the generation currently
operating at Ghubrah is the most inefficient in the system. The oldest and inefficient generating units at
Five-Year Annual Transmission Capability Statement (2011 - 2015)
Page | 71
Ghubrah will be retired in 2013 and 2014, reducing Ghubrah generation to less than 50% of its available
capacity of 2011.
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 two power plants in Al Batiniah South; Barka
Phase-I (434MW) and Barka Phase-II (681MW). A new power plant, Barka Phase-III, is under
construction, giving early power of 490MW by summer 2012 and full power of 750MW by summer
2013. The load in this area rises from 508MW in 2011 to 740MW in 2015. The power surplus increases
from 608MW in summer peak 2011 to 1123MW in summer peak 2015.
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 area significantly increases from
731MW in 2011 to 1101MW in 2015. The main generation in this area is Sohar-I power plant with an
available capacity of 605MW. There is a shortage of generating capacity of -126MW in 2011 and a
generation surplus is forecast to be from 2012 to 2015 when Sohar IPP (Sohar phase 2) plant will be
commissioned with an early power of 490MW in 2012 and full power of 750MW in 2013. The generation
surplus in this area will be 272MW, 385MW, 330MW, and 254MW in 2012, 2013, 2014, and 2015
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 336MW in 2011 reducing to 164MW in 2015 due to retirement
of old inefficient generating units starting from 2012 through 2015. In 2011 the generation surplus is
210MW decreasing to 93MW in 2014. A marginal deficiency of 12 MW is expected in 2015.
Al Dakhiliah area with its provincial load centres is exhibiting a moderate growth and has a local
generating power plant at Manah (279MW) 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 44MW in 2011 to 151MW in 2015. Power is transmitted
from Wadi Al Jizzi generating plant over about 160km from to supply the grid stations at Ibri and Al Hail
where the voltage quality is currently poor. However, the development plan for the period 2011 – 2015
will see the extension of the 220kV systems from Al Wasit in Bureimi area to Ibri in Al Dakhiliah area
and this should produce a remarkable improvement in the voltage quality.
Five-Year Annual Transmission Capability Statement (2011 - 2015)
Page | 72
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 2014 by the Sun Metals Company
(ZOOM). With the existing power station at Al-Kamil (297MW) the power deficiency is 80MW in 2011
rising to 104MW 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
500MW by summer 2013 and a total of 2000MW by summer 2014. The power surplus in this area will be
347MW, 1521MW, and 1495MW in 2013, 2014, and 2015 respectively. Compared to other areas in
Oman, Al Sharqiyah area with Sur power plant of 2000MW will have the largest surplus generating
power of about 1500MW in 2014 and 2015.

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 2012 Capability Statement.
As indicated in sections 8 and 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. It will be necessary
therefore 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 2010 daily load curve peak day).
2- According to the most recent OPWP data, there are two forecast cases: (i) base case, and (ii) high case.
The difference between the high and basic case in 2011 is 121 MW at the peak. This difference
increases in the subsequent years and reaches 1115 MW in 2015, 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 2011.
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
Five-Year Annual Transmission Capability Statement (2011 - 2015)
Page | 87
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, Bousher, Mawalleh,
Wadi Kabir, Barka Main, Seeb Main, 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 2011 maintenance period.

Appendix A: Review of Future Developments
A.1 Summary of Projects to be completed between 2011-2015 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 work on the 220kV interconnector circuits has been completed and
energized without the connection with UAE part. A new 400 kV connection between Oman and UAE has
been proposed by TRANSCO Abou Dhabi and is currently under consultancy stage. The line will be
connected between Mhadah 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 (2011-2015). These projects
are considered below under the following categories:
• Projects of 2011 system peak.
• 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 2011 to 2015 are listed and described below. It should be noted that the project numbers referred
to in the 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 2011 peak demand
Project #1: Replacing portion of existing 220kV & 132kV OHL by Underground cables
near existing & planned residential Area in Muscat
Replacement of the existing 220kV & 132kV overhead lines with underground cables near
existing and planned residential areas within the Muscat governorate is required for
Five-Year Annual Transmission Capability Statement (2011 - 2015)
Page | 92
environmental reasons. When the transmission towers were established around fifteen years ago
the Muscat area was not so heavily residential, but with urban development has come increased
health and safety considerations was given high priority. Undergrounding will also assist in
eliminating or at least reducing the voltage drop issues that occur with overhead lines. One circuit
is energized. This project was divided as phases and parts accordingly phase-1 part-1 was
completed and energized which consist of 132kV Ghubrah-Bousher and 132kV Ghubrah-MSQ
circuits and 2500mm2 cables were used to carry required capacity of each circuit. This part of the
project was energized.
Project #2: 132/33 kV Grid Supply Point at Wadi Sa’a
OETC received an application form from Majan co. to connect Al Bureimi Cement Factory (has
applied to the Majan Electricity Company for a connection) to supply a demand of 20 MW in
2009 and a further 12 MW in 2010(this project delayed due to the slow of cement factory process
of the project). To meet this requirement a new 132/33 kV, 2 x 63 MVA grid supply point has
been constructed at Wadi Sa’a, near Bureimi in the Dhahirah region. The cement factory is
located around 40 km from Mahadah (Al Wasit) grid station and so to avoid voltage drop
problems in this area the Wadi Sa’a grid station is being established with LILO arrangement and
its connected between Mahadah and Dank 132kV O/H lines 32km from Mahadah grid station.
This grid will be used for load transfer from Mahadah (Alwasit) grid station around 10MW to
release the loaded station and for cost saving in case of upgrading Mahadah 30MV transformers
as planned in the previous capability statements. The project is in commissioning stage and will
be energized soon.
Project #3: Construction of 132/33kV Grid Station & associated transmission system at
Al-Misfah area
The new 132/33 kV 2 x 125 MVA grid station at Misfah will be used to connect the new and
existing Oman Cement company load as requested by MEDC in the submitted application and
will be used for load transfers from Rusail, furthermore, to meet any future load growth and
support the system voltage within the Misfah area. The existing 132 kV Rusail – Wadi Adai
double circuit line will be looped in and out of Misfah (LILO). This project is in the
commissioning stage and will be energized soon.
Project #4: 220 kV double circuit line between SIS (Seh Al Makarim) and Al Wasit
The project of 220kV lines (66km O/H lines) between SIS and Mahadah grid stations is one of
the important projects. This project is guaranteed to release out of firm 132kV lines between
Wadi Al Jizzi and Mahadah and to ensure compliance with Transmission Security Standard. It
will also support the reactive power (Voltage) within the area. Also this connection will allow the
flow of power with the UAE (Abu Dhabi Transco) at Mahadah (Al Wasit) for the
interconnection. This will strengthen the network and improve the effectiveness of the cross-
boarder interconnector. The project is energized.
Five-Year Annual Transmission Capability Statement (2011 - 2015)
Page | 93
Project #5: Construct 132/33 kV grid station at Nakhal area with associated transmission
system
Construct 132/33kV Nakhal new grid stations (2 x 125MVA transformers with 6 no. GIS) and
connect it with Al-Falij via 132kV lines (26km). This project will assist the new load growth in
the area and also support the voltage. The load at Nakhal is now fed by two 33kV feeders from
Barka main grid station which is fully loaded. This project will release load from Barka main.
The project is energized.
Project #6: 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 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 will be designed for operation at 220kV, but energized 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. The project is expected to be completed by Q2’2011.
Project #7: Addition of third 132/33 kV 125MVA transformer at MSQ
A third 132/33 kV 125 MVA grid transformer will be installed at MSQ to shift around 70MW
from the existing two transformers in order to meet Transmission Security Standard. The project
is expected to be completed by Q2’2011.
Project #8: Addition of third 132/33 kV 125MVA transformer at Mawalleh
A third 132/33 kV 125 MVA grid transformer will be installed at Mawalleh to shift around
70MW from the existing two transformers in order to meet Transmission Security Standard. The
project is expected to be completed by Q2’2011.
Project #9: New 132/33 kV grid supply point at Qurum
The new 132/33 kV, 2 x 125 MVA grid station is required to supply new developments in Ras Al
Hamra and Qurum and to receive load transfers from MSQ and Wadi Adai grid stations. The
project is expected to be completed by Q2’2011.
Project #10: New 132/33 kV grid supply point at Muttrah
A new 132/33 kV 2 x 125 MVA grid station is planned for 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 under 2010 peak load conditions. The new grid station
Five-Year Annual Transmission Capability Statement (2011 - 2015)
Page | 94
at Muttrah is preferred to the alternative of reinforcement of the existing Al Falaj and Wadi Kabir
grid stations. The project is expected to be completed by Q2’2011.
Project #11: Adding Third transformer 125MVA at Wadi Kabir grid
A third 132/33 kV 125 MVA grid transformer will be installed at Wadi Kabir to shift around
50MW from the existing two transformers in order to meet Transmission Security Standard. The
project is expected to be completed by Q2’2011.
Project #12: Upgrade of the 132 kV double circuit line 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 previously was divided in two projects Mahadah-Bureimi and Dank- Al Hail. But
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 under 2009 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). The cable size chosen to match the capacity
of the upgraded conductor. This part of the project is expected to be in service Q2 2011.

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.12 above. This part of the project is upgrading of the Dank Al
Hail 132kV lines from wooden pole to steel tower double circuits line. The current single circuit
wooden pole is not compliant with the Transmission Security Standard requirements and
therefore in contravention of Licence Condition 26. Al Hail 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
2011.

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 2011 to 2015 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 (2011) 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 2011 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.
