It effectively decouples for any period when no gas is needed; so if those batteries let you turn off the gas generators for an hour the price decouples from gas.

The only sensible way to do this I've heard is to roll out more renewables faster and so burn less gas.

Is there some other plans you support?

That will never happen. They'll use that excuse until the very last gas powered plant is alive and then there will immediately be some other reason why energy prices have to stay the way they are.

You do realize that this is coupled with a 450MW gas power plant?

Gas is a really appealing backup option for both renewable and nuclear powered grids (at least in the absence of freely available hydropower).

But as installed power/capacity grows and batteries get cheaper, reliance on gas will hopefully decrease (and supply might get bolstered by renewable-powered synthgas within the next decades).

Does the UK not have an option for hourly-pricing? That's usually where as a consumer you can have the most gains. In the summer, with solar panels, my energy bill is negative (in The Netherlands)
