                                                                                                                  Part 1

Amendments to Part 1 of Electricity Industry Participation Code

 

4        Clause 1.1 amended (Interpretation)

(1)     In clause 1.1(1), insert in its appropriate alphabetical order:

at-risk generation means a generating unit or group of generating units as identified in the list of at-risk generation maintained by the system operator in accordance with clause 8.59A

 

(2)     In clause 1.1(1), replace the definition of connection asset with:

          connection asset—

(a)          for the purposes of Part 8, and subparts 2, 6 and 7 of Part 12, has the meaning set out in the transmission pricing methodology; and

(b)          for the purpose of Part 8 also means assets that are used for the sole purpose of connecting generation—

(i)        to the grid via a distribution network; or

(ii)       to a distribution network

 

Part 2

Amendments to Part 8 of Electricity Industry Participation Code

 

5        Clause 8.59 amended (Availability costs allocated to generators and HVDC owner)

          In clause 8.59, replace “generating unit” with “at-risk generation” in each place.

 

6        New clause 8.59A inserted (At-risk generation list)

          After clause 8.59, insert:

8.59A At-risk generation list

(1)     The system operator must publish and maintain a list of at-risk generation in accordance with this clause.

(2)     The list must:

(a)          list each generating unit, or group of generating units—

(i)        owned by a single generator; and

(ii)       at or behind a single point of connection to the grid in respect of which the generator is required to submit an offer; and

(iii)      whose failure, including the failure of the connection assets connecting it or them to a distribution network or the grid (including via a distribution network), would be treated as a contingent event (as defined in the policy statement) under normal conditions; and

(b)          where a generating unit or group of generating units satisfies paragraph (a) for a limited time only, specify a start and end date and time for the inclusion of that generating unit or group of generating units in the list.

(3)     Notwithstanding subclause (2):

(a)          the list must exclude any generating units or groups of generating units which comprise a subset of any other group of generating units which meets the requirements of paragraph (2)(a) (such that each generating unit is only included in one entry in the list); and

(b)          each generating unit or group of generating units comprising an entry on the list must have a total generating capacity of more than 60 MW.

(4)     The system operator must specify in the policy statement how it generates and updates the list.

(5)     The system operator may:

(a)          request from any participant responsible for at-risk generation information about the generation from a generating unit (> 60MW) or group of generating units (> 60MW); and

(b)          acting reasonably specify the time frame to provide the information, its format, and the method of delivery.

(6)     A participant must comply with a request made under subclause (5) within the timeframe specified.

(7)     Where the system operator already holds the information referred to in subclause (5) (e.g. from SCADA data), it may, by agreement with the relevant participant, use this information rather than requesting the information under subclause (5).

(8)     For the purpose of this clause, normal conditions excludes times—

(a)          when there is an outage of grid equipment; or

(b)          during the commissioning of the relevant generating unit or group of generating units.
