Methodology & scope

Cleared volume × clearing price × settlement-period length (clearingPrice is published as £/MW/h, not a flat per-period rate) — not volume alone. Scoped to Batteries only, same as the rest of this page — NESO's own published aggregates cover every technology, so they won't match this figure directly. An EFA block starting at 22:00 the previous day has its revenue split across both calendar days by settlement period, not attributed whole to a single day. 2 participant(s) had zero or net-negative revenue on this day (a unit can be paid a negative clearing price to provide response) — not shown as chart segments, since a donut can't represent a negative share of a whole: combined £-24,653.06.
