Cancellation of Capacity Credits
AEMO must publish the information specified in clauses 4.20.12(a), 4.20.12(c) and 4.20.12(d) of the WEM Rules after deciding (in accordance with clause 4.20.11) to cancel the Capacity Credits assigned to a new Facility that is yet to enter service. The basis for a decision under clause 4.20.11 is that no capacity associated with the Capacity Credits assigned to the new Facility will be made available to the market for an entire Capacity Year.
AEMO cancelled the Capacity Credits for the 2022-2023 and 2023-2024 Capacity Years in accordance with clause 4.20.11 for the following Facilities:

- Once every three months from the date Capacity Credits are confirmed under MR 4.20.5A; and
- Once every month between the start of the calendar year in which the date referred to in MR 4.10.1(c)(iii)(7) falls, and the date AEMO notifies the Market Participant, under 4.13.14, that the need to maintain Reserve Capacity Security of the Facility has ceased.

Government policy on capacity credits
In 2006, the Minister for Energy issued a Ministerial Direction that limited Synergy's (then Verve Energy) generation nameplate capacity. This direction was replaced in 2016, requiring Synergy to reduce its generation capacity (excluding renewable capacity) by 1 October 2018. The latest Ministerial Direction can be found below.
