Revera Energy, an energy infrastructure platform backed by global investment firm Carlyle, has announced a Final Investment Decision (FID) for its Hunterston battery storage plant in North Ayrshire, Scotland. Construction on the 400 MW/800 MWh facility is slated to commence in autumn of this year.
The Hunterston project, situated approximately one mile from the now decommissioned Hunterston A and B nuclear power stations, will provide grid-scale energy storage. It is designed to connect to SP Energy Networks’ 400kV transmission system, enhancing the stability and capacity of the national electricity network.
This latest commitment follows Revera’s recent financial close and ‘notice to proceed’ for the 200 MW/400 MWh Windyhill battery storage project in Glasgow, which is already under construction. A third significant Scottish development, the 400 MW/800 MWh Kincardine battery storage project in Fife, is anticipated to begin construction in the first quarter of 2027.
Collectively, these three projects represent a substantial investment exceeding £500 million in Scotland’s energy infrastructure, totalling a combined capacity of 1.0 GW/2.0 GWh. Revera Energy projects that this portfolio will generate approximately 550 direct construction jobs and 45 long-term operational roles, delivering significant economic benefits to North Ayrshire, Glasgow, and Fife.
Daniel Kim, CEO of Revera Energy, commented on the development:
In Case You Missed It:
“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, who assumed office in May 2024, welcomed the investment:
“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.”
