The Australian Energy Market Operator (AEMO) manages the electricity and gas systems and markets across Australia, helping to ensure Australians have access to affordable, secure and reliable energy.

Prior to joining BGER, a member of our ESG Advisory team contributed to AEMO’s Reserve Capacity mechanism for the SWIS, Certification of the Reserve Capacity and other market research analysis for gas and electricity systems.

Specifically, the contribution was made to three of AEMO’s Wholesale Electricity Market (WEM) Electricity Statement of Opportunities, including the 2022 WEM ESOO, which forecast that sufficient electricity supply will be available to meet projected demand until at least 2025 in WA’s major power system.

The WEM ESOO is an important step in the Reserve Capacity Mechanism (RCM), which ensures electricity reliability in the SWIS. The report sets the Reserve Capacity Requirement (RCR) for 2024-2025, which has been determined at 4,526 megawatts (MW).

The WEM ESOO projected annual peak demand growth of 0.9 per cent over the 10-year outlook period, due to increased energy use by industrial loads, growth in new housing connections, and the uptake of electric vehicles.
