Rhondda Cynon Taf (HAB-19)
21 MW in South Wales and Gloucester. Everything on this page is read from published data for the 364 days to 27 September 2026, or is labelled as an estimate.
What it is
| Registered power | 21 MW response and reserve auction registration |

How we know. The register names no owner for the Hirwaun units. The capacity market register holds a Pulse Clean Energy Limited site called Hirwaun 900 metres away, which is the usual gap between a postcode centre and a capacity market grid reference, and HIRWB is Hirwaun shortened.
Market registers name the party that sells into the market, which for a battery is usually an optimiser under contract rather than the owner. This unit is registered only in the response and reserve auctions, so the seller is the participant NESO's auction results name, and Elexon's register carries no entry to check it against. How we tell them apart
What it earned
| Line | 364 days to 27 September 2026 |
|---|---|
| Balancing mechanism | not published |
| Response and reserve auctions auction implied | £0 |
| Capacity market | no 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
The nearest comparables
