It looks as though today will be the first day that there has been no coal generation on the National Grid. It seems that the last station was switched off at 11 pm yesterday.

I rather doubt the accuracy of this report.

It is beyond reasonable doubt that no coal was burnt in a grid connected power station for over 24 hours.

However I am almost certain that this is NOT a first, last summer there were several days including full days of 24 hours, in which no coal was burnt.
Indeed it was discussed on this very forum, a respected member observed it and enquired if this was a "first" and I replied "not quite it first happened a few days ago" (not a few days ago from today, but a few days before the post enquiring if it was a first")

Perhaps someone could locate the thread ?

And BTW, I don't think that the "switching off at 11pm" was permanent !
I expect some coal burning this autumn and winter, though much reduced if compared to previous years.

That thread last year when coal fell to 0% was
coal contributing 0%

I think that previously the output may have been zero, but not for a whole day / 24 hour period. The report also only covers metered generation, but is there any private coal?

"Britain's longest continuous energy period without coal until now was 19 hours - first achieved last May, and again on Thursday." - according to the BBC - http://www.bbc.co.uk/news/uk-39675418

Of course this report is rubbish. It may be that no output was from coal stations, but it was still hot and running as normal, just waiting for the wind etc. to stop. It would be interesting to see the rotating reserve as well as the actual outputs! It takes at least 24 hours to start a large coal station from cold, so no coal for short periods is simply not possible.

When coal is shown as zero, AFAIK coal burning plant is normally fully shut down, i.e. "cold and dark" and not held in hot standby or spinning reserve state.

Under present day conditions, the very short term reserve for second by second use as demand alters is normally partly loaded gas turbine plant that is operated in "frequency sensitive mode" whereby output is automatically increased or decreased in response to frequency changes. Hydro electric plant can also respond within seconds to changes in demand.

In the longer term of a few minutes up to a few hours, increases in load are catered for by instructing more gas turbine plant to generate, run up times vary from minutes to a few hours.

I see that the biomass-burning power stations are running flat out though. These are mostly converted coal-fired stations.

Yes, but they're "carbon neutral"... if you ignore transportation of the fuel round the world, etc.
