About Larks Green Solar Farm
Larks Green Solar Farm is a 50 MW solar farm near Iron Acton in South Gloucestershire. It has been operational since May 2023, according to the planning database. It shares its site with a 49.5 MW battery, which the planning database lists as operational since November 2024 (Larks Green battery storage, live on its own page).
Its 50 MW of registered generating capacity is spread across one balancing mechanism unit. Every half hour each unit tells the grid how much it will generate (its physical notification): that is the live figure above, and GridMonkey records it every half hour for the chart. The live percentage uses this registered figure, not the 70 MW installed that the planning database gives.
Solar farms generate in daylight only: their output climbs from sunrise to a midday peak and falls to zero at dusk, higher on clear days and in summer. Few solar farms report their output one by one: Larks Green Solar Farm is one of only eight in Great Britain that do, while the government lists 1,386 as operating. Why so few?
