The Australian Energy Market Commission (AEMC) has released updates to key reliability settings that apply to the national electricity market (NEM).
Under the National Electricity Rules, the NEM's market price cap (MPC) and cumulative price threshold (CPT) must be adjusted in line with the consumer price index by 28 February each year.
The MPC is the maximum price that can be reached on the spot market during any dispatch and trading interval. The CPT is the maximum price across seven days’ worth of trade.
On 7 December 2023, the Commission made a final rule to increase the base rate of the MPC and CPT, which will progressively increase from 1 July 2025 through to 1 July 2027.
The values for 2024-25, the new base values, and the CPI-adjusted amounts for 2025-26 are as follows.
From 1 July 2024 to 30 June 2025 | New Base Value (2022) | From 1 July 2025 to 30 June 2026 | |
MPC | $17,500/MWh | $18,600/MWh | $20,300/MWh |
CPT | $1,573,700/MWh | $1,674,000/MWh | $1,823,600/MWh |
The updated values and underlying calculations for 2025-26 are in a schedule of reliability settings on the AEMC website.
