The Coordinator of Energy (Coordinator) has conducted a review of the Benchmark Capacity Providers, which are used to determine the Peak and Flexible Benchmark Reserve Capacity Prices (BRCPs).
The Coordinator must determine the Benchmark Capacity Providers within six months of a revised Electricity Storage Resource Duration Requirement (ESRDR) being published in AEMO’s Electricity Statement of Opportunities (ESOO).
AEMO’s 2025 ESOO was published on 24 June 2025 and included an ESRDR of 6 hours, an increase from the previous ESRDR of 4 hours.
On 30 September 2025, the Coordinator published the 2025 Determination of the Benchmark Capacity Providers.
In summary, the Coordinator has determined that:
The Benchmark Peak and Flexible Capacity Providers will be lithium battery energy storage systems with:
• 200 MW injection;
• 1200 MWh energy storage;
• a 330 kV connection at a location determined by the ERA.
Benchmark Reserve Capacity Prices will be determined on a gross Cost of New Entry basis.
