I have been monitoring the power generation for the UK National Grid since 2000. Here is an update covering the period between November 2022 until February 20th 2023. Note that I have also generously corrected for wind power by factoring in unmetered wind farms (using an enhanced factor of 1.6). The solar energy data is generated by the University of Sheffield and is based on a their modelling using national sunshine data. All other values are directly from the Elexon interface . Here below are the overall results.
The interplay of gas usage to balance wind power generation is best seen in the following graph.
There were two successive wind lulls in early December and two short ones in Jan/Feb. These were very expensive since gas prices have more than doubled since last year for reasons we all know.
The following table gives the net contribution of each fuel to UK power generation
Something I do not yet understand is why total “metered” power generation appears to have fallen slightly in under two years!
