Doncaster (10MW)

What it is

Who owns it and who trades it

How we know. The control filing gives the company to Doncaster Power Projects Limited of Tickton Hall at three quarters or more since June 2022, with Nash Business Capital Nominees Limited holding between a quarter and a half. Forepower Limited and Catfoss Finance Limited held it before that.

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

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, estimated from metered peers

Elexon publishes no metered output for this registration, an auction unit rather than a balancing mechanism unit, so nothing can be derived for it. What can be said is what its peers did: 15 units of about 1 hour in England and Wales, metered, earned between £3.49 and £26.07 per kilowatt a year with the balancing legs and the position outside the balancing mechanism together, £5.55 at the median. Applied to this unit's 10 MW that is £56k, in a range of £35k to £261k. An estimate from other batteries, never this one's figure. Method

Where it stands

Percentiles, so 90 means better than nine in ten of the cohort named beside it, on that measure alone, over the same 364 days. Rates are pounds per kilowatt per year, annualised over the days the unit has been on the system, the same figures the performance league ranks on. A high position in the taken-in table is not a fault: a constraint asset is paid to charge, and charging is its job.

The nearest comparables

The five nearest in size in England and Wales, and this battery among them, ranked by what each was paid for every kilowatt it holds over the 364 days to the same date. They run for about the same length of time. Same market, same rules, same weather.
