Maldon

MP: Sir John Whittingdale (Conservative) England Data to July 2026

Maldon has 139 MW of clean power (all solar) approved and still not built: enough to supply a year's electricity to 50,000 homes. When the wires are too full to carry the power, Britain pays wind farms to switch off instead. No wind farm here is paid that way — almost all of it goes to wind farms in Scotland. That cost is shared across every bill in Britain, so households here pay for it too: about £92 a year per household, £3.8m across the constituency's 41,803 homes. There is also 58 MW of wind running here on the local network. If that gets switched off, no national record shows it. A 100 MW battery was refused planning here in 2022; while discharging it could have supplied about 350,000 homes.

Ranks 38 of 650 for clean power approved and not built.
