While it is true that we do not know what precipitated this particular blackout, the issue of higher penetration asynchronous generation is a known problem which we at Carbon Trust are working on on a daily basis. I posted some links on LinkedIn. www.linkedin.com/posts/activi...

This is exactly what I am saying to all of our clients. DT wanted to "save coal" www.bloomberg.com/news/feature..., but couldn't as the gas price was simply too low. Likewise, he will not be able to halt the energy transition to lower cost renewables due to underlying economics, but can slow it.
Trump Made a Promise to Save Coal in 2016. He Couldn’t Keep It
Despite the campaign vow, 2020 coal production is expected to be down 31%. The bleak coal outlook could cost the president support in the Nov. 3 election.

Is an example of a renewables dominated system for Norway (mainly hydro) and s gas dominated system in UK. There is a cable between the two countries, but insufficient capacity to fully equalise the prices.
As more wind comes on in the next couple of years, our prices will start dropping a lot!

That said, we do need to build out the network (paid through bills) and deploy storage (investor funded with no subsidies bar a relatively small amount from Capscity Market).
retail bill costs will come down in the near future as gas is pushed off the grid

Producing energy from lower cost sources *is* good for economic growth.
Both solar PV wind have been awarded low strike price CfDs (a proxy for Levelised cost of energy) and are being built as we speak. Low, that is, compared to natural gas plants (ca. £100/MWh now).

And unfortunately you need to build the system to max need - so yes, you can solve Dunkelflaute with nuclear, hydrogen, gas CCS or VERY large volumes of batteries - it is not self evident which of these is least cost (a mix is probably the right answer with lots of interconnection with our friends

Has a price been agreed? Thought it was going to be in the region of £75/MWh, with market prices around £120/MWh average

That said, the cost of storage has come down since then and the degree of flexibility in the system is arguably higher (the jackpot would be proper V2G.
20m - 30m vehicles with 50kWh batteries = 1,000 - 1,500GWh of storage (if all were plugged in & available), plus 7kW x 30m capacity (210GW!)

It has to be compared on a system-level cost, i.e. you can't just compare LCOE of offshore wind against nuclear.
I used to do this analysis and at the time (6 years ago) the value of adding SZC to the system compared to the alternative of wind + storage to cover Dunkelflaute was a no brainer.

Balancing costs should be considered on the round. In the case where CfDs and RObare paid to turn down, that looks like a large cost. However, some of this cost is offset by lower support costs. Net on the bill, that effect is probably small, but just wanted to point out. P462 will reduce BM further

BM spiked to £5,250/MWh today, Rye House - I was told. Could be messing with pricing algo.

Bit much to charge £1,000/MWh on wholesale prices of £350/MWh, no? Especially since IMRP CfDs will pay back significantly during those hours (granted, small volumes) meaning that the actual net cost is probably around £335/MWh.

Well - RO generation was 80.3TWh in 2022/2023 while CfD generation was around 30TWh, almost 50% increase over 2023.
Adding contracts signed, but under construction, this will rise to around 131TWh by 2031/2032

I try not to use X, but there is still more material there. Also, the “discover” algorithm in Bluesky is poor - mainly shows me people I follow already.
I do try to avoid engaging with X material though.

If you assume a rise in typical demand from 2.9MWh (or whatever it is these days) to around 4 - 5MWh in an electrified system, a (probably minimum) £20/MWh reduction in power price relative to higher carbon generation systems would be £80 - £100 per customer per year or £2.4bn - £3bn with 30m custom

Agreed that this would be a good exercise, but they should also commission a robust (or three) counter factual models to assess prices / bills with and without CP2030. The fall in average power prices caused by near zero operations will dwarf policy / network costs. 1/2

Possibly so, but it would be extremely embarrassing for the government to have spent the political and actual capital to not sustain low carbon generation.
The targets are not THAT totemic in that if the cost is excessive or the timing is too short, something will give to keep delivery “reasonable
