Devilla deal draws institutions into grid storage.

Copenhagen Infrastructure Partners sold minority stakes in the 500 MW Devilla battery storage project in Scotland on 8-9 June 2026, with Scottish National Investment Bank and Nuclear Liabilities Fund among the buyers. The transaction brings fresh capital to one of Europe's largest grid-scale storage developments now under development.

Two contracts underpin the project's commercial footing. A 10-year optimisation agreement with SSE and a 15-year capacity market deal together provide long-term revenue certainty, while supporting renewable integration across Britain's grid.

Nuclear Liabilities Fund chief executive Melissa Hope pointed to the deal's strategic fit. "NLF is pleased to partner with CIP and Scottish National Investment Bank on this battery storage project," she said, adding that the investment supports UK energy security and economic growth.

The deal reflects a broader shift among large institutions, which are treating grid-scale storage less as a niche infrastructure bet and more as a core portfolio position.

For Scotland, the implications extend beyond a single site. Devilla would bolster the country's standing as a clean energy destination at a time when grid stability pressures across the UK are growing. At this scale, battery storage can absorb surplus renewable generation and discharge it during periods of high demand, reducing volatility for consumers and network operators.

Copenhagen Infrastructure Partners has indicated it may apply similar partial-sale structures to other assets in its pipeline as appetite for contracted storage projects grows. Whether Devilla's construction schedule holds will draw close attention from the wider market, given its potential to set terms for future large-scale storage transactions across Europe.
