Network solutions company Alcemi has been granted planning permission to develop “one of Europe’s largest energy storage facilities”.

The 2-hour 500MW/1,000MWh energy storage facility could begin construction in the coming months, subject to a final investment decision.

The project will be developed in partnership with renewable energy investment firm Copenhagen Infrastructure Partners (CIP) via its Flagship Funds and is planned to be situated in Coalburn, Scotland, just to the southeast of Glasgow.

Alcemi chose the project’s location to support the national transmission system by limiting the impact of network constraints. According to the group, the project has “undergone extensive environmental impact assessments to ensure it meets the highest sustainability and safety standards”. The site is also expected to benefit from landscaping measures to limit the visual impact of the project site.

Sister site Solar Power Portal previously reported that Alcemi and CIP had partnered for the development, construction and operation of a 4GW portfolio of UK energy storage assets back in March 2022. This 500MW energy storage site is the fruition of this partnership and will contribute to this growing portfolio.

This however, is not the only UK partnership CIP has sought. Earlier this year, CIP entered into a similar partnership with Amberside Energy to develop a 2GW portfolio consisting of solar and battery energy storage system (BESS) projects across the UK.
