Oh FFS here we go again.

With a minimum derated margin of around 4.2GW across the demand peak and zero
loss of load probability for every half hour period today there always was
plenty in reserve.

201MWh of OCGT on a total supply of 886704MWh (20171106 @ 2300 - 20171107 @
2300) is 0.02% or to put it another way SFA.

Plus as predicted a long time ago the sun did set today exactly when expected,
when the sun shone and PV output peaked the gas inlet valves on many CCGT's were
throttled and less gas was burnt reducing CO2 emissions. The heat input did not
stay the same and efficiency was affected by a small part of a percentage point.
No thermal plant of any description was left 'ticking over' in case the wind
suddenly dropped or the sun was obscured by cloud.
