How revenue is counted
Energy revenue uses hourly mean prices and output, so it differs a little from settlement at 15-minute intervals. Node prices load a few days per update, newest first; days without them fall back to system lambda and are marked. Ancillary service revenue is the DAM award at the DAM clearing price (real-time AS awards under real-time co-optimization are not in the disclosures yet). Start-up costs count the hot start offer for every start; a unit off long enough for an intermediate or cold start cost more. Submitted offers are capped by ERCOT's cost verification, so the offer basis is an upper bound on what the unit said its energy was worth, not an audited cost.
