Who are CE Electric UK? We are an electricity distribution busines

transporting electricity from the nationaltransmission system, and local generatioto 3.8 million domestic and businesscustomers.

Our network covers an area of 25,000

square kilometres, consisting of more th31,000 substations and around 91,000 kof overhead lines and underground cable

Our role is to ensure a reliable, consisten

and safe supply of electricity. We own and rent electricity meters. Other than to meet our own needs, we d

buy or sell electricity. We operate our service territory 24/7

through five delivery zones, with teamsbased at 14 local service centres.

3/65

Our network operates from 132,000 Volts to 230 Volts - designedoriginally to transport electricity from the national grid to wherever

power is needed.

The move to locally connected generation presents new opportunitand challenges.

We operate in one of the UKs most active regions for distributed

generation enquiries and projects

The market is relatively new and developing UK government

published its microgeneration strategy last week

This included:

a government keen to encourage dialogue

between network companies and the

microgeneration industry on connection

issues

Ofgem, the industry regulator, continuing to

work with network companies to improve the

connection process

Why are we holding todays event?

In direct response to clear stakeholder interest at our Have Your Say eventsheld earlier in 2011, in Gateshead and Leeds

To help businesses and organisations understand the end-to-end process foconnecting microgeneration and, how to take advantage of feed in tariffs

To help raise awareness of what is involved which can reduce overall costs;avoid unexpected delays; and, ensure projects run smoothly

To promote the competitive market for new connections

A significant opportunity for us to learn from you, build great relationships, anuse your feedback to further improve our service

We look forward to assisting with the connection of more of your generation tour network

We see ourselves as partners with our customers and the communities we ser

What is G83 generation?

G83 is an industry standard for Small Scale Embedded Generators (SSEGs)

Energy Networks Association Engineering Recommendation G83/1-1

Recommendations for the Connection of Smallscale Embedded Generators (Up to

16A per Phase) in Parallel with Public Low-Voltage Distribution Networks

Stage 1 a single unit within a single customers installation

Stage 2 multiple units in a close geographic region, under a planned programme o

work

The stage 2 definition is being clarified in the next issue of G83

Small Scale Embedded Generator (SSEG)

A source of electrical energy and all associated interface equipment, rated up to an

including 16 A per phase, single or multi phase 230/400 V ac and designed to opera

in parallel with a public low voltage distribution Network. 16A at 230V is 3.68kW

Note that with this definition it would be the output of the system after powering the

inverter not the (slightly higher) output of the solar panels that would be relevant.


16/65

5

Why 16A per phase?

The 16A requirement is from the Electricity Safety, Quality and Continuity Regulations Regulation 22

22.(1) Without prejudice to regulation 21, no person shall install or operate a source of energwhich may be connected in parallel with a distributors network unless he

(a)has the necessary and appropriate equipment to prevent danger or interference with tha

network or with the supply to consumers so far as is reasonably practicable; (b)has the necessary and appropriate personnel and procedures to prevent danger so far areasonably practicable;

(c)where the source of energy is part of a low voltage consumers installation, complies witBritish Standard requirements; and

(d)agrees specific requirements with the distributor who owns or operates the network.

(2) Sub-paragraphs (b) and (d) of paragraph (1) shall not apply to a person who installs or operaa source of energy which may be connected in parallel with a distributors network provided thsub-paragraphs (a) and (c) of paragraph (1) are complied with; and

(a)the source of energy does not produce an electrical output exceeding 16 amperes perphase at low voltage;

(b)the source of energy is configured to disconnect itself electrically from the parallelconnection when the distributors equipment disconnects the supply of electricity to thepersons installation; and

(c)the person installing the source of energy ensures that the distributor is advised of theintention to use the source of energy in parallel with the network before, or at the time of,commissioning the source.

There are a number of basic issues associated with connecting

distributed generation to the wider electricity network

Electrical Issues Contextual IssuesVoltage

Rise & Step

Protection G83 protection is not sufficient to prevent overvoltages

it should protect the generator.

RoCoF can not always discriminate between loss of

mains and system disturbances. For safety it should be

slightly trip happy. This becomes an issue with

increasing generation penetration.

Fault level Varies by technology and location, but customer has a

high degree of control over their contribution to the

issue

Reverse power flow

Thermal ratings We are now seeing 11kV connected generation

exporting to NGET.

Clustering Where it is good to develop one renewable gene

due to resources, ease of planning etc, it is norm

good to develop others. Generator applications cluster, overloading one a

leaving others untouched and leading to comme

queuing issues.

Planning consents

Particularly for overhead lines but also for connecpoint substations

The LV system was designed for a thermal rating and voltage drop ca

by a domestic load of 2kVA ADMD (after diversity maximum demand

One house mighttake up to around18kVA; a hundredhouses would onlytake a maximum ofaround 200kVA.

Costs to customers,were traditionallyminimised bydesigning thesystem so that themaximum length of

cable and theminimum crosssection wereutilised.

To optimise this theno-load voltage

was set as high aspossible within thestatutory limits.

DNOs are involved in a wide range of projects from testing of new

product applications to design of innovative networks

Orkney registered power zone Project to create and test thelogic and control systems required for automatic management

of a constrained distribution network with large volumes of

distributed generation.

Flexnet Major project to explore the commercial, technicaland consumer issues around the development of flexiblenetworks and to develop solutions to the barriers to

implementation.

Energy innovation centre Collaborative, mentoredprogramme to bring new innovations into the distributionindustry from, primarily, SMEs.

Loss of mains A series of projects designed to mitigate anderadicate distributed generation problems such as islanding

and generation protection.

Superconducting fault limiter The development of improvednetwork equipment based on state of the art materials

technology. This will improve network resilience in conditions

caused by an increased volume of distributed generation and

avoid the need to replace assets.

Increasing breadth of sites being supported particularly in electricity

However, competition in electricity lags some way behind that of gas

Why the Discrepancy?

DNO CiC processes characterised by: Application process for point of Connection.

Lengthy and complex DNO connections process.

Protracted process on agreeing connection arrangements. Excessive requirements for land rights.

Delays and conflict in design approval.

Delays in getting DNO staff booked for work.

DNO failure to turn up when promised. DNO reasons to abort work.

Delays in inspection regimes.

Previously DNOs Have No Incentive: To develop services that improve the customer experience.

To engage with ICPs/IDNOs with a genuine view/ intent to deliversolutions
