Revera Energy has announced a final investment decision (FID) for its 400MW/800MWh Hunterston battery energy storage project in North Ayrshire, Scotland.
The Carlyle-backed developer said construction is expected to begin in the third quarter of 2026, following the recent financial close and notice to proceed for its 200MW/400MWh Windyhill battery storage project in Glasgow, where construction is already under way.
The company is also progressing the 400MW/800MWh Kincardine battery storage project in Fife, with construction expected to start in the first quarter of 2027.
Together, the three projects represent a combined 1GW/2GWh of battery storage capacity and more than £500 million ($680 million) of investment, forming one of Scotland’s largest battery storage portfolios.
Revera said the developments are expected to support around 550 direct construction jobs and create 45 long-term operational roles across North Ayrshire, Glasgow and Fife.
Daniel Kim, chief executive officer of Revera Energy, said: “Hunterston’s FID represents an important milestone for Revera and reflects the progress we are making across our Scottish portfolio.
“Together, these three projects represent more than £500 million of investment in Scotland and will play an important role in strengthening the electricity network for homes and businesses across the country, while supporting jobs, economic growth and long-term infrastructure development. We are committed to working closely with local communities, stakeholders and government as we bring these projects forward, and hope to leave a lasting positive legacy in each of the areas where we operate.”
First Minister of Scotland John Swinney said: “Revera’s decision to commit to three major projects in Scotland, worth over £500 million, is a vote of confidence in this country’s skills, economic policies and energy future. This is one of the largest battery storage portfolios being built anywhere in the UK, and it demonstrates that Scotland is an internationally competitive destination for clean energy infrastructure investment.
“These projects will create jobs during construction and permanent roles for years to come, and they will help power Scottish homes and businesses with cleaner, more reliable energy.”
Richard Hoskins, managing director in Carlyle’s infrastructure group, said: “At Carlyle, we invest in infrastructure businesses and assets that are critical to a resilient and affordable electricity network.
“The scale of investment across Revera’s Scottish portfolio reflects our commitment to Scotland and the opportunities we see to support critical grid infrastructure, local economic growth and long-term value creation for communities and investors across the country.”
According to Revera, all three projects have secured positions within the UK’s Clean Power 2030 framework, underlining their role in supporting a more flexible electricity network and enabling greater use of renewable energy resources across Scotland.
Revera Energy is developing battery storage and other energy infrastructure assets in the UK and Australia.
