West Lothian

29 MW in Stirlingshire and Fife. Everything on this page is read from published data for the 364 days to 27 September 2026, or is labelled as an estimate.

This registration has been superseded. The battery here has sold as Byers Brae (EDF01N) since 21 August 2026; this code, sold by F & S Energy Ltd, has not been paid in the auction results since they begin on 31 March 2025. The page stays for the record, and the unit is no longer counted in fleet totals or ranked in the league.

How we know. The register names no owner. The capacity market holds Byers Brae Battery Storage belonging to Gresham House Energy Storage Holdings plc 880 metres away.

Market registers name the party that sells into the market, which for a battery is usually an optimiser under contract rather than the owner. Elexon's balancing mechanism unit register names the seller here and the name is checked against it on every build. How we tell them apart

Balancing mechanismnot published
Response and reserve auctions auction implied£0
Capacity marketno agreement we can attach
Three lines together£0

Balancing is offer revenue and does not net off the cost of the power. The response and reserve figure is the value implied by the published auction results, award quantity times clearing price times the length of the delivery window, and not a settled payment. Capacity market income is the cleared price raised for inflation where the auction set a base period, split by month on EMRS's weights. Method

Outside the balancing mechanism

No estimate for this registration. The battery sells under a newer code now, and anything estimated for it belongs on that page, so it is not counted twice. Method

Why every line reads zero

This registration has never appeared with an award or an acceptance in any market we read. That is the whole public record.
