EDF confirms activation of the 50 MW / 50 MWh Kemsley lithium-ion system at the National Grid substation. KEMB-1 is the sole mapped battery unit; the separate Kemsley energy-from-waste plant is excluded. MW is discharge power, not stored energy; the 40.1 MW registry reference remains separate.

Operator capacity sourceWhole-site registered total: 40.1 MW, including retired units.
Registered capacity is the value retained in the committed BM-unit source snapshot. “Not retained” means the registry no longer supplied a positive figure; it does not mean the unit historically had no capacity. If a unit with a retirement event publishes a non-zero live declaration, the live declaration keeps it in the operating fleet pending review.
About this asset
Kemsley is a operating battery site in South East England. It has 1 non-retired (0 unverified) and 0 retired mapped Balancing Mechanism unit, with 50 MW on the displayed capacity basis.
The source catalogue has no site coordinate, so the explorer shows a regional position rather than an exact location.
Current output is the operator’s declared Physical Notification. Metered output is published later and is shown as the solid portion of the history chart; outage shading comes from REMIT notices.
