About Devilla Battery Energy Storage System
The Devilla project is a 500MW, 2-hour duration, lithium-ion battery energy storage system (BESS) located near Kincardine, one of three battery storage projects in Scotland being co-developed by Copenhagen Infrastructure Partners (CIP) and London-based energy storage developer Alcemi. Devilla is expected to be operational in early 2028 and will be among the largest battery storage systems of its kind in Europe.
The project has a high level of contracted revenues through a 10-year optimisation agreement with SSE plc, alongside a 15-year capacity market agreement, providing visibility and a stable foundation for returns while maintaining exposure to market upside.
Why we invested
Our investment in the Devilla project aligns with our net zero mission to address the climate crisis through a fair and sustainable economy.
As Scotland continues to generate greater amounts of clean energy, the electricity grid can struggle to manage and distribute it to other parts of the UK. This can result in curtailment, where wind and solar producers need to switch off or dial back their electricity generation to avoid overloading the grid.
There are also problems with renewable energy intermittency when the wind isn’t blowing or the sun isn’t shining. Battery energy storage systems (BESS) act as buffers, storing excess energy to avoid curtailment, then releasing it later as needed.

Nischal Agarwal, Partner at CIP, said: “As CIP’s development and construction portfolio of UK BESS projects continues to progress and grow, we look forward to welcoming Scottish National Investment Bank and Nuclear Liabilities Fund as new equity partners on our Devilla site. 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.”
Melissa Hope, Chief Executive of Nuclear Liabilities Fund, added: “NLF is pleased to partner with CIP and the Bank on this battery storage project. This investment aligns with our strategic investment objectives while supporting UK energy security and economic growth.”
