More Green Records and Milestones

So in conclusion
If we ignore carbon pricing and security of supply then gas ccgt makes most sense for the entire uk power requirement.
There would be a role for storage to cover the daily demand cycle but needs a 7-10x fall in battery prices and smart demand might be able to acheive the same via demand smoothing
Nuke at current prices makes no sense
Wind and solar at current prices makes no sense but may only need to fall in price by half. Battery plus renewables might make sense if consumers/producers faced spot prices such as the tide tariff.
We have not considered whether if/when batteries for peak management become economic this may also make renewables better value.

You can put costs on risk, both carbon and gas supply security is low risk its price is negligible

Nuke at current prices makes no sense

Not in the UK

Wind and solar at current prices makes no sense but may only need to fall in price by half.

Yes it would be great if offshore wind fell towards £25/MWh even if the payments were stretched over a longer period maybe 25 years instead of 15 years.

Battery plus renewables might make sense

You should see it as two different things, renewable should be seen as fuel and batteries as control and both can be apprised on their own merits and costs

A conventional power station is both fuel and control

Batteries dont make renewable better, they may allow more renewable into the system but it doesn't make renewables better
