Gas burning plant tolerates load changes and start/stop cycles better than coal, but efficiency and services life are somewhat reduced thus.

CCGT plant can often produce some electricity fairly quickly from the gas turbine, but the steam turbine wont produce anything until steam has been raised.


You say "somewhat" whilst ESB CCGT site staff used rather stronger language whilst discussing these issues directly with a colleague of mine. The official management line seems to be that this is not an issue.

Wind power currently at over 8GW, impressive but some way short of a record.
Due to the low national load of only 24GW, wind power was over one third of total UK consumption, and that I suspect IS a record, in percentage terms.
No coal burning plant in use, which is still unusual in the winter, though becoming the norm at other times of year.

All figures as indicated on gridwatch, other sources may differ.

I love the way Christmas day never has an evening peak. I guess because nobody's cooking in the evening: we're all on turkey sandwiches Very Happy

I noticed this website which has good daily, weekly and monthly summaries.
http://www.mygridgb.co.uk/2016-vs-2017/

Interesting to note that the UK is worryingly dependent on gas for about 40% of its electricity supply this year. Wind's share of generation has increased quite a lot, 7 to 11% even from 2016 to 2017. Coal has declined from 40% share to 5% share in the last 6 years. Not good from a national security perspective.

You've a better appetite than me then. Either that or I make a bigger pig of myself with Christmas dinner and so can't eat any more in the evening!

Wind power at present is the largest contributor to the grid, at 9.5, with CCGT in second position at 9.1 and nuclear doing well at 7.3 but still in third place.
I suspect that this is the first time that wind has been the biggest source during the daytime, though it has been fairly regularly achieved overnight.

The all time record for wind is 9.68, IIRC, wonder if a new record might be set today ?

All figures in GW and as indicated on the gridwatch site, other sources may vary.

Indicated wind power twice, briefly reached 9.70 GW an hour or so ago, so that is another new record though only by a small margin.

Indicated power from wind is at present 9.8GW, another new record, AFAIK.
Over a third of national demand is being met by wind.

Well that record did not last long ! About 30 minutes in fact.
Indicated power from wind is now 10.05GW, a new all time record.

As indicated on gridwatch, other sources may vary. The true figure will be a bit higher than the indicated figure, due to small wind turbines that are not metered in real time.

EDIT TO ADD 10.27GW a little later.
