Do you know how much coal capacity we have, in total?

wiki says 7.3 GW, are any closed ones kept moth-balled for

coal out in the rain indefinitely ...


6.5GW, with no other coal capacity in reserve.

Permanent HV disconnections and removal of connection assets totgether with
network reconfigurations have already been made at any coal plant withdrawn from
the market

From next Autumn it's currently 5.25GW of declared coal


But to continue, as generation declarations remain until closures are confirmed
and declarations withdrawn it's a bit worse than that, 1.5 GW is due to go from
Aberthaw so it's going to be closer to 4GW, maybe a bit below.

Taking their actual Transmission Entry Capacity as of today for 'coal' is
11304MW, but that includes Unit 4 at Drax which is already Biomass so that total
is slightly overstated by around 645MW and 2000MW from Cottam which has already
closed but not yet surrendered TEC.

Uskmouth, included in the 11304MW figure above is not running either and is
undergoing biomass conversion for completion this year so that's another 230MW
of coal capacity lost

So with Cottam (2000MW) along with West Burton (1987MW) and Fiddlers Ferry
(1455MW) surrendering their TEC as of 1st April 2020, that brings the total to
5632MW (less another 645MW for Drax Unit 4) Bringing the total down to just
over 5GW, factor in the predicted closure at Aberthaw and it's potentially 3.3GW
of Coal capacity going into next winter (Ratcliffe 2021MW and Drax 1290MW being
the last two sites)

Checking the live figures this morning Cottam has already stopped generation,

West Burton is currently running all four units in the 400-450MW range.

Aberthaw also isn't running at the moment and nor is Fiddlers Ferry
