Alcemi has received planning permission to build a 2-hour 500MW (1000MWh) energy storage facility in Coalburn, Scotland.
Developed in partnership with Copenhagen Infrastructure Partners (CIP), through its Flagship Funds, the facility will store renewable energy during periods of excess generation, releasing it back into the system during periods of peak demand.
The project is expected to prevent around 1.6 million tonnes of CO2 emissions over 35 years.
Alcemi chose the project’s location to support the national transmission system by limiting the impact of network constraints, helping to reduce the overall energy costs for consumers and lowering the carbon intensity of the UK power sector.
Working in close collaboration with local authorities and stakeholders, the project has undergone extensive environmental impact assessments to ensure it meets the highest sustainability and safety standards, Alcemi said.
Specifically, biodiversity will be promoted across the site through the maintenance of peat reserves, tree and wildflower planting, and the creation of new habitats.
The site will also benefit from landscaping measures to limit the visual impact.
The final investment decision from CIP is expected later this month, with construction commencing shortly thereafter.
James Forster, chief development director of Alcemi, said: “We’re delighted Alcemi’s first project has received planning permission, it’s a fantastic result after so much hard work.
“Energy storage is vital in supporting the UK’s transition to net zero and decarbonisation, and we’re thrilled to be making such a significant contribution with one of the largest projects in Europe.”
