I notice on grid watch the power requirement at the moment (17:30) is
55.41 GW.
Nuclear as usual is flat out, Coal is rising and looks near its limit,
CCGT (I presume this is gas) also looks to be near its limit and Wind,
well as usual when it is needed it is rubbish.
The other generation and imports does not amount to much.

Just How much can the UK generate in GW and how near are we to its
limit, also what happens if we go over our maximum generation limit?
