No.167 of 650 · approved, not built MP: Perran Moon (Labour) England

Camborne and Redruth

Camborne and Redruth has 35 MW of clean power (all solar) approved and still not built: enough to supply a year's electricity to 13,000 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, £3.9m across the constituency's 42,696 homes.

10 MW of wind is running in this constituency, but it sits on the local network rather than the national grid — so if it is paid to switch off, no national record shows it. That is why this seat has no figure here: not because nothing happens, but because nobody publishes it. The £ figure for this seat is a floor, not a zero.

35 MW

of clean power — all solar — approved and still not built, enough to supply a year's electricity to 13,000 homes. Approved at least two years ago; waiting on the grid, not on planning. That is 0.6× the renewable capacity actually running here.

£3.9m

is what the grid gap costs this constituency's 42,696 households in a year between them — £92 each, about 51 days of one home's electricity.

The £92 per household is a national figure — identical in every GB seat. Only the seat total varies, with the number of households · NESO · how we worked this out

What this page does not show

Smaller wind farms on the local grid are also switched off; national data does not show it, so the £ figure here is a floor, not a zero. Offshore wind is counted nationally, never per seat. The planning database can run a quarter behind reality.

Electricity does not travel from a particular project to particular houses. Everything generated goes into the national grid and everyone draws from that shared pool, so "enough for X homes" is a way of sizing the electricity — not a claim that these homes would be powered by this site. Battery storage is counted separately from generation: it moves power in time rather than making it.

Planning statuses come from the government's planning database (REPD), which records what was decided and when, but not why. Where a project was refused we say so and name the authority; for the reasons, look up the planning reference on that council's own register. How to check any figure on this page →
