No.41 of 650 · approved, not built MP: Stuart Andrew (Conservative) England

Daventry

Daventry has 130 MW of clean power (all solar) approved and still not built: enough to supply a year's electricity to 47,000 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, £4.0m across the constituency's 43,684 homes. There is also 69 MW of wind running here on the local network. If that gets switched off, no national record shows it.

here
69 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.
130 MW
of clean power — all solar — approved and still not built, enough to supply a year's electricity to 47,000 homes — about as many homes as this constituency has. Approved at least two years ago; waiting on the grid, not on planning. That is 1.7× the renewable capacity actually running here.

£4.0m
is what the grid gap costs this constituency's 43,684 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 →
