Check a site for a new battery

Type a postcode. The check reads what this site already holds about the grid around it: the connection points nearby, what is queued at the nearest and who holds each position, what the running batteries nearby earned last year, and the room the local network operator publishes.

How to read it

The verdict. NESO, the system operator, lets 0 MW of new batteries that need a transmission study into its next application window. For a battery of that kind the chance of a connection today is close to nil, anywhere in Great Britain. A battery small enough to skip that study goes to its local network operator, so the most room that operator publishes in the postcode’s supply point area, for exporting and importing alike, is shown beside the verdict.

The queue. One block for each project queued at the nearest transmission connection point, sized by its battery megawatts and shaded by gate. Gate 2 is the firmest place in the reformed queue. The dates of those positions say how late a newcomer would join. Every name opens the applicant in the Atlas. A battery under the size limit queues with its local network operator instead, so the batteries accepted on the local network nearby are listed too, from the six operators’ own registers, each compared with NESO’s queue.

The earnings. What each running battery within 15 km earned per kW over the last year, from the meter, the balancing mechanism and the reserve and capacity auctions. Each is set beside GRID’s published figure for the same year for a battery of its own hours, because a one hour battery and a two hour battery are different businesses. Trading and the energy used to deliver response are worked out from the meter; the rest is measured. Every name opens the battery’s own page, which lists the same lines. The zone’s transmission charge, NESO’s forecast for 2031, says whether the grid wants power there.

What it leaves out

Distances run from the centre of the postcode. 348 connection points in NESO’s registers carry no map position, so they are left out rather than guessed. Transformer ratings are not read yet. This is a first screen from public files; only a network operator’s offer is firm.
