The 35 MW/70 MWh project, which uses Tesla Megapack technology, is now energised and preparing to enter commercial operation. It can store power from sources such as wind and solar and release it back to the grid when demand is high, enough to power around 120,000 homes for two hours. The site will strengthen the UK's clean energy supply and support the wider transition to a more reliable, flexible and lower-carbon electricity system.
Battery storage plays a critical role in the UK's energy system by helping to make better use of homegrown renewable power, strengthening energy security and reducing reliance on imported fossil fuels. By storing electricity when demand is low and releasing it when demand is higher, projects such as Skeeby can help reduce curtailment of clean power, support grid stability and contribute to lower costs for consumers over time.
The energisation of Skeeby also marks an important milestone for Harmony Energy following its recently announced strategic investment from Alpiq, a leading Swiss energy services provider and electricity producer. Skeeby is the first Harmony Energy site to go live since the investment was announced, demonstrating the company's continued momentum as it accelerates delivery of its battery storage pipeline across Europe.
“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” said Peter Kavanagh, CEO of Harmony Energy. “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.”
Beyond energy, Harmony Energy works to deliver projects that protect nature and bring lasting benefit to the communities that host them. At Skeeby, that includes biodiversity measures such as new planting and habitat improvements, alongside support for initiatives like Richmond Bike Park, a new free-to-access bike skills park expected to launch in late 2026.
