Innova Sells 1GW Enderby BESS to Fidra

• Innova sells its 1,025MW Enderby BESS to Fidra Energy, completing its UK exit and boosting grid flexibility. The deal underscores surging investment in long-duration storage.

Innova has sold its 1,025-MW Enderby battery energy storage system (BESS) project in central England to Fidra Energy, the firms said. The deal completes Innova’s exit from a planned project that is among the UK’s largest BESS developments, reflecting accelerating investment in grid-scale storage.

The Enderby project is expected to help balance renewable generation, enhance grid flexibility, and strengthen energy security as the UK builds a more renewable-heavy power system. Fidra Energy said it will continue expanding its utility-scale storage portfolio amid rising demand for long-duration flexibility solutions alongside growing solar and wind capacity.

What does Fidra’s acquisition of Innova’s 1,025-MW Enderby BESS signal for UK storage demand?

• Signals that utility-scale battery storage demand in the UK is shifting from early-stage development toward bankable assets with clear grid value.
  
• Highlights strong market pull for large, central-England projects capable of providing grid services such as frequency support, peak shaving and constraint management.
  
• Suggests investors expect increasing system need for dispatchable flexibility as renewable generation grows, reducing curtailment and improving integration of solar and wind.
  
• Indicates confidence in the commercial viability of long-duration and grid-scale BESS—particularly as policymakers, network operators and generators increasingly plan around flexibility resources.
  
• Reinforces that capacity additions are being prioritised not just for generation, but also for reliability and resilience, supporting energy-security objectives during tighter supply-demand conditions.
  
• Points to accelerating competition among storage developers and investors for operationally ready projects, reflecting a maturing sector and faster consolidation of promising pipelines.
  
• Implies network-driven procurement is likely to intensify, with more value placed on projects that can relieve bottlenecks and improve connections for renewable-rich regions.
  
• Supports the broader view that the UK storage market is moving toward a portfolio model—developers acquiring large projects to scale quickly rather than building everything from scratch.
