Copenhagen Infrastructure Partners (CIP) has agreed to sell minority stakes in its flagship Devilla battery storage project in Kincardine to the Scottish National Investment Bank and the Nuclear Liabilities Fund, marking a significant step forward for one of Europe’s largest energy storage developments.
The 500MW lithium-ion battery energy storage system (BESS), designed with a two-hour duration, is set to play a pivotal role in strengthening grid stability and accelerating the integration of renewable energy across the UK. Once operational in 2028, Devilla is المتوقع to rank among the largest facilities of its kind in Europe.
CIP will retain a majority stake in the project and continue to lead delivery through construction. The development is underpinned by a 10-year optimisation agreement with SSE plc, alongside a 15-year capacity market agreement, providing long-term revenue visibility while retaining exposure to market upside.
Nischal Agarwal, Partner at CIP, said the partnership reflects growing momentum in the firm’s UK battery storage pipeline.
“As CIP’s development and construction portfolio of UK BESS projects continues to progress and grow, we look forward to welcoming the Scottish National Investment Bank and Nuclear Liabilities Fund as new equity partners on our Devilla site,” he said. “Once commissioned in 2028, Devilla will be one of Europe’s biggest operational BESS projects. The delivery of Devilla, alongside CIP’s Coalburn 1 and 2 projects, will improve the UK’s energy security and reduce costs for British consumers through enhanced system flexibility and access to more low-cost renewables.”
Devilla forms part of a wider portfolio of three transmission-connected BESS assets co-developed by CIP and Alcemi, all currently under construction in Scotland. Together, the projects will deliver 1.5GW of power capacity and 3GWh of storage—enough to supply more than 4.5 million households for up to two hours.
CIP is also advancing an additional 4.5GW of battery storage projects across Scotland and England, underlining the scale of its ambition in the UK energy transition.
For the Scottish National Investment Bank, the investment aligns closely with its mission to support net zero infrastructure and long-term economic resilience.
