AEMO has identified a potential requirement to secure up to 174 MW over the 1 December 2022 to 31 March 2023 period. As such, AEMO is commencing the supplementary Reserve Capacity (SRC) process for the 2022-23 Capacity Year in accordance with clause 4.24 of the WEM Rules.

The maximum contract value per hour of availability is $2,380.23 per MW for any SCC that AEMO will accept. A Maximum Availability Percentage (as defined in the WEM Procedure: Supplementary Reserve Capacity) of 7.4% applies.
