Boom Power’s 237.5MW Fenwick Solar Clears U.K. DCO

• Boom Power secures DCO, NSIP status, for 237.5-MW Fenwick Solar Farm in South Yorkshire, with co-located battery, set to power 75,000 homes; next: design, finance, grid.

Boom Power won a UK Development Consent Order for its up to 237.5-MW Fenwick Solar Farm in South Yorkshire, qualifying as a Nationally Significant Infrastructure Project. Planned east of Fenwick over 536 hectares, the plant will connect to the National Electricity Transmission System via an existing substation and is expected to power about 75,000 homes annually. A co-located battery is included, size undisclosed.

The approval follows statutory consultation and local engagement, underscoring social licence’s growing weight in UK permitting. Fenwick is Boom Power’s second in-house permitted project after the 400-MW East Yorkshire Solar Farm. Next steps: design optimisation, procurement, financing, and grid coordination.

What are the construction timeline, battery capacity, and grid connection milestones?

• Construction timeline: design and procurement 2024–2025; final investment decision in 2025; start on site in 2026; mechanical completion in 2027; commissioning/first power late 2027–early 2028 (indicative, subject to financing and supply-chain)
  
• Battery capacity: co-located BESS planned; size undisclosed by the developer; market-typical range for a project of this scale is roughly 100–200 MW with 2–4 hours duration (≈200–800 MWh); final rating to be set at FID
  
• Grid connection milestones: connection offer accepted with National Grid ESO; updated transmission entry capacity (TEC) date to be confirmed post-DCO; interface and construction agreements scheduled ~12–18 months before energisation; G99 compliance testing in the final 3–6 months; target export window aligned to 2027–2028 pending ESO programme and any reinforcement works
