More on that excess of wind and solar power:

To have enough renewable power to run the country in winter, there will inevitably be far too much at times in the rest of the year.
In reality, we know that there won’t be enough power in winter when the wind stops blowing, but that’s another topic.
But based on Labour’s Clean Power 2030 Plan of tripling offshore wind and solar power and doubling onshore, NESO have conveniently provided the hourly data for a typical week in summer – Sheer CP12 on the link provided above.
Running their numbers through, the week averages out with generation of 45.3GW. Demand in summer is around 30GW. Although demand is expected to increase, much of this will charging EVs at night and powering heat pumps in winter, so it is unlikely we will see much effect during the day in summer.
What NESO figures tell us is that a third of daily generation will have to be constrained. At an average price of £100/MWh, that works out at a cost of £3.3 billion, just for summer alone.
The actual constraint payments could be much higher, because mostly it will be offshore wind affected. It is likely that the AR7 strike prices will be over £100/MWh, and offshore wind farms already operating are being paid considerably more. If you have a contract for £150/MWh, you are not going to accept £100 to switch off.
