The battery energy storage system (BESS) near Richmond has been energised and is preparing to enter commercial operation.
Harmony Energy has announced that its Skeeby Battery Energy Storage System is now connected to the electricity network.
The company says the facility can store enough electricity to power around 120,000 homes for two hours.
The development, which uses Tesla Megapack battery technology, is designed to store electricity, including power generated by renewable sources such as wind and solar, before releasing it back to the grid when demand is higher.
Harmony Energy says battery storage facilities can help balance supply and demand and reduce the amount of renewable electricity which goes unused when generation exceeds immediate demand.
The Skeeby facility is the first Harmony Energy site to be energised since the company announced a strategic investment from Swiss energy company Alpiq.
Peter Kavanagh, chief executive of Harmony Energy, said: “Skeeby is an exciting milestone for Harmony Energy, not only because it brings another important battery storage project online, but because it is the first site to be energised since our strategic investment from Alpiq.
“That investment gives us additional backing to accelerate the delivery of projects like this across the UK and Europe, while continuing to operate with the same team, brand and development expertise that have underpinned Harmony Energy’s growth to date.”
The company says landscaping and biodiversity measures at the Skeeby site include new planting and habitat improvements.
Harmony Energy is also supporting Richmond Bike Park, a planned free-to-use bike skills facility which is expected to open later in 2026.
The Skeeby battery facility is now undergoing preparations ahead of starting commercial operations.
