The Coalburn project will comprise a 200MW battery energy storage facility with approximately 800MWh of storage capacity, making it one of the largest battery storage projects in the UK. The project sits within Scotland’s rapidly expanding battery storage sector, which is playing a critical role in enabling greater use of renewable power, improving grid flexibility and supporting the UK’s transition to a cleaner electricity system. The project is also the first four-hour duration battery storage project connected to the transmission network to reach financial close.

Dentons’ work covered project and procurement documentation for the matter, including BESS supply and long-term services arrangements, balance of plant supply and long-term services documentation, management services arrangements, transformer arrangements, grid-related documentation, legal due diligence support, BOP Supply Contract documentation, BOP LTSA, employer and contractor PCGs, and final contract and financial close workstreams.

The Dentons team was led in the UK by Gareth Tenner (lead project partner) and Mel Mahon (senior associate), with support from lawyers across Dentons’ UK energy, infrastructure and projects team.

Mr Tenner said: “Coalburn has required a highly coordinated, commercially focused legal effort across procurement, project contracts, diligence and closing workstreams. It is a major storage project in a critical market and we are delighted to have helped Zenobē reach this milestone.”

Mr Mahon added: “The project reflects the pace and complexity of the UK battery storage market. We were pleased to support Zenobē on the detailed contractual framework needed to deliver a project of this importance.”
