Eelpower acquires Silkstead BESS from Balanced Grid Works
The Silkstead BESS is located to the south east of the Winchester substation in England and will commence construction in 2027, with commercial operations expected to start in 2028.
Eelpower Energy, a UK grid-scale battery storage platform backed by Equitix, Aware Super and the National Wealth Fund, has completed the purchase of the 50MW/200MWh Silkstead battery energy storage project near Winchester, England, from Balanced Grid Works.
The Silkstead BESS is located to the south east of the Winchester substation and will commence construction in 2027, with commercial operations expected to start in 2028, according to a press release.
This is Eelpower Energy’s fifth acquisition since its launch in September 2025.
Eelpower Energy is aiming to build, own and operate over 1GW of grid-scale battery assets in the coming years with a view to being a leading owner-operator of flexibility on the GB electricity system, the press release said.
“This acquisition demonstrates our ability to originate and execute attractive opportunities with high-quality counterparties such as Balanced Grid Works, in order to deliver on the commitment of Equitix, Aware Super and the National Wealth Fund to invest in the infrastructure needed for a cleaner, more flexible and more resilient electricity system in Great Britain,” Mark Simon, Chief Executive of Eelpower Energy, said.
“We developed an excellent working relationship with the entire Eelpower Energy team. This approach enabled us to deal with and address any issues that arose during the due diligence and sale completion process in a timely and equitable manner,” Kevin Parr, Director of Balanced Grid Works, said. “We look forward to watching Eelpower Energy move the Silkstead project to the next stage of its development.”
