Statkraft

Owns 1 battery at 1 site, 50 MW, which is 0.7 per cent of everything operating in Great Britain. It sells that power itself: every registration names a company of its own as the seller.

Who sells its power

The balancing mechanism register names the company allowed to sell each unit's power. That company is usually an optimiser or a supplier working under contract, which is why the registers cannot answer the ownership question on their own. Where the seller is one of the owner's own companies, the row says so.

What it was paid

The three published lines, added up across the fleet for the 364 days to 6 September 2026. Wholesale trading income is invisible for every owner, not just this one, and nothing here nets the cost of charging. The rate is per kilowatt of current capacity.

How we know

Confirmed means a control filing at Companies House, or the owner's own published statement, names the company. Probable means the evidence is strong and indirect. Named means the register leaves the owner blank, the balancing code carries the owner's initials, and a sibling unit at the same site is already settled. Each chain below is printed once, with the batteries it settles.

Confirmed Neilston Battery 1
The register names no owner. Neilston Greener Grid Park is Statkraft's own 50 MW transmission connected battery, built under the second stability pathfinder, and Statkraft is also the lead party here. Source

Attribution. A battery belongs to whoever the documents name today, so a fleet that changed hands during the year credits the whole year to the current owner. Groups are joined only where a filing joins them; a company that holds through several vehicles appears once, under the name at the top of the chain. Directors and registered offices are never used as evidence on their own. Why the registers cannot answer this question
