“Gate Closure” means the point in time prior to physical delivery when offers made by a generator with respect to a generating station or individual generating unit or by a supplier become final and changes to offers may no longer be accepted except in exceptional circumstances to be defined by the Commission under the Market Arrangements for Electricity Rules to be developed under Regulation 5;

“Generator” means a holder of a licence to generate electricity granted under Section 14 of the 1999 Act and the Board acting in its capacity as ESB Power Generation;

“Individual Generating Unit” means such a unit of a generating station;

“Locational Marginal Price (‘LMP’)” means the price per mega-watt hour (MWh) of electricity at a given node;

“Market Operation Date” means the date on which the new system of trading in electricity established by Regulation 3 comes into operation, which date shall be determined by the Commission following public consultation, but shall, in any event, be no later than 19 February 2006. That date shall be published by the Commission by a notice in a daily newspaper published and circulating in the State at least one month beforehand;

New System of Trading in Electricity

3.

• (2) The new system of trading in wholesale electricity will be a mandatory centralised pool (“the spot market”) requiring all electricity exported to or imported from the transmission system or distribution system to be sold to and bought from the SMO.

• (3) The spot market will apply to all generators and suppliers except with respect to those classes of generating stations or individual generating units determined by reference to installed capacity or amount of electricity exported or likely to be exported to the transmission system or distribution system, in any calendar year or the primary source of energy used for the production of electricity so exported or any combination of these as determined by the Commission from time to time as exempt in whole or in part from such application and defined under the Market Arrangements for Electricity Rules to be developed under Regulation 5.

• (4) The spot market will be an electricity only market and there will be no separate capacity payments.

• (5) Generators whose generating stations or individual generating units are not called on to generate because of constraints on the transmission and/or the distribution systems, or because their offered price is too high will not receive any payments from the spot market in accordance with the Market Arrangements for Electricity Rules to be developed under Regulation 5.

• (6) Generators, with respect to each individual generating unit unless exempted under paragraph 3 of this Regulation by the Commission, shall provide offers to the SMO for each trading period and may change these offers up to gate closure.

• (7) A supplier may elect for some or all of its demand to be certified by the SMO as dispatchable. The balance of a supplier's demand will be treated as non-dispatchable. For its dispatchable demand a supplier will provide offers for each trading period and may change these offers up to gate closure.

• (8) The SMO shall produce and make public week-ahead and day-ahead pre-dispatch runs which will indicate the projected spot market prices and generating station and individual generating unit dispatch schedules prior to actual dispatch.

• (9) The spot market shall be cleared and corresponding dispatch schedules determined simultaneously for each trading period, which trading period shall be thirty minutes or such other period of time as determined by the Commission from time to time and detailed in the Market Arrangements for Electricity Rules to be developed under Regulation 5.

• (10) The SMO shall simultaneously resolve system feasibility and market dispatch including losses, transmission constraints, reserve requirements and other relevant system security requirements when determining the dispatch schedule and when setting the LMPs in accordance with the Market Arrangements for Electricity Rules to be developed under Regulation 5.

• (11) The SMO shall procure and manage ancillary services including reserves for system support, and shall manage contingencies which may occur during a trading period in co-ordination with the electricity market in accordance with the Market Arrangements for Electricity Rules to be developed under Regulation 5.

• (12) Prices offered by generators with respect to generating stations or individual generating units and by suppliers must be no less than the negative Value of Lost Load (VoLL), and no greater than the positive Value of Lost Load (VoLL).

• (13) A generator whose offer is accepted by the SMO will be paid the locational marginal price (LMP) pertaining to the node at which it is located for actual volumes traded in the spot market subject to the rules governing same as set out in the Market Arrangements for Electricity Rules to be developed under Regulation 5.

• (14) Suppliers trading in the spot market will pay a uniform wholesale spot market price for electricity irrespective of location. Suppliers of dispatchable demand, as certified under Regulation 3(8 will pay the LMP at the node at which they are located.

• (15) The method of calculation of the uniform wholesale spot market price and of the LMPs shall be determined by the Commission and set out in the Market Arrangements for Electricity Rules to be developed under Regulation 5.

• (16) LMPs will be set by the SMO immediately prior to the beginning of each trading period.

• (17) The Commission shall reserve the right to set electricity prices in the spot market and/or to introduce price controls in exceptional circumstances, such circumstances to be defined under the Market Arrangements for Electricity Rules to be developed under Regulation 5.

New System of Trading in Electricity

4.

• (2) The Commission shall impose a suite of financial hedge contracts on or between ESB Power Generation generating stations or individual generating units, the terms and conditions, including price and duration, of such contracts to be determined by the Commission from time to time. The Commission shall determine from time to time the methodology for making these contracts available to Counterparties.

Market Arrangements for Electricity Rules.

5.

• (2) All generators, subject to Regulation 3(3), and suppliers shall comply with the MAE Rules.

• (3) The MAE Rules shall be in such form and contain such detail as the Commission shall decide.

EXPLANATORY NOTE.

(This note is not part of the Instrument and does not purport to be a legal interpretation.)

These regulations establish a new system of trading in electricity replacing the existing system of trading in electricity. The new system of trading will be a mandatory centralised pool. All generators and suppliers unless exempted will be required to buy and sell electricity through the pool. The regulations make further provision for supplemental rules to be developed by the Commission to give effect to the new system of trading in electricity.
