Copenhagen Infrastructure Partners Sells Minority Stakes In Scotland’s Devilla Battery Storage Project To New Investors

Copenhagen Infrastructure Partners (CIP), acting on behalf of its Copenhagen Infrastructure IV (CI IV) fund, has reached an agreement to sell minority stakes in the Devilla battery storage project to the Scottish National Investment Bank and the Nuclear Liabilities Fund (NLF). The transaction brings two new long-term investors into one of the UK’s most significant energy storage developments while allowing CIP to retain a majority ownership position and continue leading the project through construction.

Located in Kincardine, Scotland, the Devilla project is a 500MW lithium-ion battery energy storage system (BESS) with a storage duration of two hours. Once operational, it is expected to become one of the largest battery storage facilities in Europe, playing an important role in improving grid reliability, enhancing energy security, and supporting the integration of renewable energy into the electricity network.

The project benefits from a strong revenue framework that provides long-term stability. Devilla has secured a 10-year optimisation agreement with SSE plc, one of the leading renewable energy and flexible power generators in Great Britain and Ireland. In addition, it has a 15-year capacity market agreement, offering predictable revenue streams while still allowing investors to benefit from favorable market conditions.

Devilla forms part of a broader battery storage portfolio being developed by CIP and energy infrastructure developer Alcemi. It is one of three transmission-connected battery storage projects currently under construction in Scotland. Together, these projects will deliver a total power capacity of 1.5GW and provide 3GWh of energy storage. Once completed, the facilities will be capable of supplying enough electricity to power more than 4.5 million households for two hours.

Beyond these projects, CIP is also developing an additional 4.5GW of battery storage capacity across Scotland and England, highlighting its growing commitment to strengthening the UK’s energy infrastructure.Nischal Agarwal, Partner at CIP, said the investment reflects the continued growth and progress of the company’s UK battery storage portfolio.

He welcomed the Scottish National Investment Bank and Nuclear Liabilities Fund as new equity partners in the Devilla project and noted that, once commissioned in 2028, the facility is expected to be among the largest operational battery energy storage systems in Europe. He added that Devilla, along with CIP’s Coalburn 1 and Coalburn 2 projects, will help improve the UK’s energy security, increase system flexibility, and enable greater access to low-cost renewable energy, ultimately reducing costs for consumers.

Robin Tayal, Investment Director at the Scottish National Investment Bank, emphasized the importance of battery energy storage systems in strengthening energy security and grid stability. He noted that Devilla’s strategic location will help facilitate renewable energy integration while improving flexibility and reliability across the electricity system.

Tayal also expressed confidence in the partnership with CIP and the wider investor group to support the successful delivery of the project.Melissa Hope, Chief Executive of the Nuclear Liabilities Fund, said the investment aligns with the fund’s long-term investment strategy while also contributing to the UK’s broader energy security and economic growth objectives.

She highlighted the value of collaborating with CIP and the Scottish National Investment Bank on a project that supports the transition to a more resilient and sustainable energy system.As renewable energy generation continues to expand across the UK, large-scale battery storage projects such as Devilla are becoming increasingly important.

By storing excess renewable electricity and supplying it back to the grid when needed, these facilities help balance energy supply and demand, improve grid resilience, and support the transition toward a cleaner and more flexible energy network.
