Conrad Energy
Owns 7 batteries at 7 sites, 129 MW, which is 1.9 per cent of everything operating in Great Britain. It sells 126 MW of that itself and the rest through EDF Energy Customers Limited.
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.
| Seller | Batteries | MW | Of this fleet |
|---|---|---|---|
| Conrad Energy (Trading) Limited the owner's own company | 5 | 101 | 78% |
| Conrad Energy (Trading) Ltd the owner's own company | 1 | 25 | 20% |
| EDF Energy Customers Limited | 1 | 3 | 2% |
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.

| Response and reserve auctions | £2.9m |

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 Blackpool, Conrad (TORQUAY), Conrad (SWINDON), Conrad (MIDSOMER), Conrad (FLITWICK)
The control filing on Conrad (Blackpool) Limited runs to Conrad (Glyme) Limited and, before July 2023, Conrad Energy (Holdings) II Limited. The sibling companies share the same Abingdon registered office. Source
Confirmed Winchester (WNCHB-1)
The register names no owner. The capacity market holds a Winchester site of the same 19 MW belonging to Conrad Energy (Holdings) II Limited, 1.2 km from this unit's postcode centre, and the connection register carries Conrad (Winchester) Limited at Nursling grid supply point as built. Source
Probable Grflb-1
The register names no owner and places this unit only by postcode district. The capacity market holds a 33.8 MW Flitwick site belonging to Conrad (Glyme) Limited inside that district, the lead party is Conrad Energy (Trading) Limited, and the capacity is close. The site itself has not been confirmed. 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
