Battery energy storage developer Alcemi has been awarded planning permission for two battery energy storage system (BESS) projects totalling 1.5GW in Scotland.

The portfolio consists of the 1GW/2GWh Rawhills Energy Storage projects in Coalburn, south of Glasgow and the 500MW/1,000MWh Devilla Energy Storage project located in Fife, north of Edinburgh.

Both projects were developed in collaboration with Copenhagen Infrastructure Partners (CIP) through their Flagship Funds, which focuses on climate solution technologies such as offshore and onshore wind, solar photovoltaics (PV), and biomass.

CIP confirmed that the 500MW Devilla project was ready to commence construction in December last year.

According to CIP the final investment decision for the projects is expected later this year, with construction to commence shortly afterwards.

“This is a fantastic achievement for Alcemi and advances our mission to facilitate the UK’s transition to clean energy,” said James Forster, chief development director at Alcemi.

“These projects will provide stability to the grid, limit network constraints, and are vital to maximising our offshore wind generation. They are a key component to ensuring renewable energy is transported across the country.”

In March 2022, Alcemi and CIP also partnered for the development, construction and operation of a 4GW portfolio of UK energy storage assets.
