The UK’s failing renewable strategy is a national embarrassment.
Critically low wind power, for nearly the whole of yesterday, resulted in extremely high prices, with the two remaining coal units at Drax offering to save the day at £4,000/MWh ($5,444/MWh), nearly 100 times the wholesale price normal before the current crisis started, with many other fossil fuel generators also riding to the rescue at staggering prices.
Indeed, yesterday saw a new record for the total daily cost of balancing the GB electricity grid.
The previous record of £38 million ($52 million), twenty times the current daily average, was smashed by a margin of £6 million ($8M), with the new record standing at £44.7m ($60.84M).
The causes are easy to identify from the Balancing Mechanism Reporting Service’s own chart of the Transmission System fuel mix.
Wind power, the dark blue bars, was extremely low for most of the day, with a minimum of only 1 GW, under 5% of its capacity.
Minimum wind generation coincided neatly with peak demand, and as a result system prices reached stunning levels, with a maximum of just over £4,000 ($5,444) a megawatt-hour, nearly 100 times the wholesale price normal before the current crisis started, as can be seen in this BMRS chart:
These prices brought coal and gas back onto the system to save the day, but emergency measures are expensive, and the cost to consumers and the wider economy was just short of horrifying.
When these remaining fossil fuel generators are no longer on the system the costs of securing supply will rise still further.
In fact, batteries and hydrogen storage on the scale required are very unlikely to be built in the time required, and have severe environmental downsides that mean they may never be built at all.
And even if actually built, the costs of balancing the system with these technologies will make yesterday’s record look like a bargain.
Grid balancing expenditures in the UK are already ten times their pre-wind and solar levels; in the future they will rise still further, consuming a significant fraction of national wealth.
The UK climate strategy is all but entirely committed to renewables and it isn’t working. With the best will in the world, and however much they care about climate change, neither individual households nor the wider economy can stand these costs.
Needless to say, such problems are in fact well understood in other parts of the world, which is why neither China nor India is following us down the wind and solar route. The costs are economically destabilizing.
Fortunately, there is an alternative; unwind the renewables’ failure, and put the UK firmly back on an engineerable Gas to Nuclear strategy, as described by Dr. Capell Aris and the present author in their paper, Realism or Utopianism? A proposal for the reform of the Net Zero Policy.

Way too bad their Wind Turbines failed now their using power that comes from Coal they very same stuff some Nit-Wits want left in the ground this is so ironic
The irony is strong with this one. It looks like the UK has finally figured it out; the United States and Australia, not so much. May the irony be with you, until they figure it out as well.
