CONSTITUENCY BRIEFING · ENERGYMAP.APP

Horsham

MP: John Milne (Liberal Democrat) England Data to July 2026

Horsham has 51 MW of clean power (all solar) approved and still not built: enough to supply a year's electricity to 19,000 homes. Britain's grid bottlenecks still add to bills here: about £92 a year per household, £4.0m across the constituency's 43,452 homes. A 57 MW battery was refused planning here in 2024; while discharging it could have supplied about 200,000 homes.

Ranks 125 of 650 for clean power approved and not built.
