Quinbrook Infrastructure Partners and Energy Optimisation Solutions (EOS) will invest around £160m (€185m) to develop one of the largest battery storage systems in the UK.

Uskmouth Energy Storage, jointly owned by Quinbrook and EOS, has secured development rights for a new 239MWh/460MWh battery energy storage system on the former Uskmouth coal-fired power station site acquired from Simec Atlantis Energy

Construction is envisaged to take up to 18 months, with the project expected to become operational towards the end of 2024.

Uskmouth Energy Storage will own and operate the battery storage system in south Wales and has a 30-year contract with Simec Atlantis to supply energy to the company.

Rory Quinlan, co-founder and managing partner of Quinbrook, said: “Almost 10% of UK grid capacity is expected to be provided by battery storage by 2030, representing an estimated £20bn in new capital investment.

“Project Uskmouth is a timely example of how specialist energy infrastructure investors like Quinbrook can identify new opportunities of substantial scale and positive impact arising from the energy transition.”

Keith Gains, senior director of Quinbrook, said investments in projects such as Uskmouth, supported by industry innovators like Habitat Energy, reinforced Quinbrook’s strategic moves into the supply of critical flexible capacity, storage and grid support infrastructure.
