EAC mock auction results | National Energy System Operator
Summary
NESO publishes mock auction results for its Enhanced Ancillary Services (EAC) platform, showing weekly test runs of response-reserve procurements ahead of live operations. The dataset includes buy orders, sell orders, results by unit, and summary statistics from mock auctions scheduled for late September 2023. Live EAC auctions will run daily with results published on a separate page.
Why it matters
This represents NESO testing market mechanisms for procuring response and reserve services through competitive auctions rather than bilateral contracts. As such, it signals a shift toward market-based procurement of ancillary services, though the mock results reveal little about actual pricing or participation until live operations begin.
