Published NEM analyses and dashboards
AC interconnectors carry a published operating margin of 25 to 50 MW. Regulation FCAS could shrink it without a new market
AEMO holds every interconnector below its limit by an Operating Margin: Modelling Approximation + Dispatch Error + Measurement Error. It writes the number into the constraint equation as a named…
Does P5MIN beat persistence for regulation FCAS prices?
The price of regulation FCAS changes every five minutes. AEMO publishes a forecast for it — P5MIN — but is it actually worth using, or does it perform the same as just assuming nothing changes? We…
The NEM burns twice as much raise regulation as lower — and ~100 MW of the answer is missing from the data
AEMO procures raise and lower regulation in near-identical volumes: 223.6 MW and 220.1 MW respectively, averaged across the mainland over the twelve months to June 2026. Dispatch is not symmetric.…
