South West Devon

MP: Rebecca Smith (Conservative) England Data to July 2026

South West Devon has 20 MW of clean power (almost all solar) approved and still not built: enough to supply a year's electricity to 7,700 homes. Britain's grid bottlenecks still add to bills here: about £92 a year per household, £3.8m across the constituency's 41,475 homes.

Ranks 198 of 650 for clean power approved and not built.
