Summary of Certified Reserve Capacity

Summary of Certified Reserve Capacity 2025 Key Points 

• The document reports the Certified Reserve Capacity (CRC) assigned by facility for the 2027-28 capacity year (1 October 2027 to 1 October 2028).

• Two types of capacity are assigned: Peak CRC and Flexible CRC.

• Total assigned:

  • Peak CRC = 6,375.141 MW

  • Flexible CRC = 4,077.068 MW

How it works and next steps

• These assignments include only those facilities that:

  1. Completed a Bilateral Trade Declaration, and

  2. Where required, lodged their Reserve Capacity Security (RCS). 

• The assigned CRC is indicative only; the final allocation of capacity credits will depend on further steps, particularly:

  • Assessing Network Access Quantity (NAQ) for each facility (i.e. how much capacity they can actually deliver given network constraints) up to their assigned CRC.

  • Only the portion of CRC up to the NAQ becomes Peak Capacity Credits. Flexible Capacity Credits are capped by Peak Capacity Credits for each facility.

2025 Facility Examples

Here are a few sample facility assignments (Peak CRC / Flexible CRC):

• Alinta Sales, ALINTA_PNJ_U1 — ~142.447 MW / 142.447 MW

• Collie Battery, COLLIE_BESS2 — ~293.56 MW / 293.56 MW

• Synergy, COLLIE_ESR4 — 250 MW / 250 MW

• NewGen Neerabup GT1 — 330.6 MW peak / 330 MW flexible
