Edinburgh-headquartered Fidra Energy has completed the acquisition of the Enderby battery storage project in Leicestershire from Innova, the largest UK independent developer of renewable energy projects and data centers, in a deal that brings Fidra's total UK battery energy storage system pipeline to over 4GW.

Deal Details and Project Scale

The transaction, announced, was completed for an undisclosed sum. The Enderby project is an advanced-stage development expected to deliver up to 1,025MW of capacity, which would place it among the largest battery storage projects in the UK upon completion.

Innova secured planning consent for the site from Blaby District Council in May 2025, after which the project was confirmed as eligible to participate in the first long-duration energy storage cap and floor scheme application process. A regulatory decision on that application is expected during the summer of 2026. A final investment decision on the Enderby project is anticipated in 2027, with commercial operations targeted for 2029.

Strategic Significance for Fidra Energy

The acquisition marks a significant expansion of Fidra Energy's UK footprint. Backed by institutional investor EIG and the National Wealth Fund, Fidra describes itself as a European battery energy storage platform with a strategy focused on developing, building and operating large-scale storage projects across the UK and key European markets. With Enderby now in the portfolio, Fidra's total UK pipeline exceeds 4.1GW.

Morris Van Looy, Chief Growth and Strategy Officer of Fidra Energy, said the deal represents another major milestone in the expansion of the company's UK portfolio and reflects the company's ambition to deliver large-scale battery storage infrastructure at pace to support the UK Government's Clean Power 2030 Action Plan. He added that Fidra would leverage Innova's experience working with local stakeholders and communities as the project advances.

Innova's Track Record in BESS Transactions

For Innova, the Enderby sale is the third utility-scale, transmission-connected battery storage project the company has divested within the past twelve months.

Daniel Mushin, Chief Finance and Investment Officer of Innova, stated that those three projects, once built, will together amount to over 2.4GW of new capacity, representing a substantial contribution toward the UK's clean energy targets. Mushin described Fidra as an excellent counterparty and indicated that Innova expects to continue working with them going forward.

Fidra's Existing Construction and Development Activity

The Enderby acquisition builds on active development work Fidra already has underway elsewhere in England. Following a capital raise completed in 2025, construction has begun at the company's Thorpe Marsh site in Yorkshire, a project sized at 1.4GW with 3.1GWh of energy storage capacity.

A separate site at West Burton in Nottinghamshire, rated at 500MW and 1.1GWh, is due to reach a final investment decision in June 2026. Both the Thorpe Marsh and West Burton projects are expected to be fully operational by 2028.

Policy Context and Grid Need

The deal comes as the UK government's Clean Power 2030 Action Plan sets out a target for between 22GW and 27GW of short-duration battery storage to be operational by 2030.

Battery energy storage systems are considered critical infrastructure in the energy transition, enabling greater integration of renewable generation into the electricity grid, reducing curtailment of wind and solar output, and enhancing overall system flexibility and resilience.
