And it didn‘t need to be on, as there is plenty of cheaper power going spare at present, not least around 20GW of Gas generation that’s been sat doing nothing for almost a week. One suspect they are burning simply to get rid of their stockpile, as that is going to be cheaper than transporting it away in 5 months time.
This week has been remarkable for power geenration, it has seen the highest ever combined wind and solar output, the lowest ever fossil fuel output, the lowest ever Gas output, and consequently the lowest ever CO2 emmissions (down at 9g/kwh for a time yesterday, which is only 2% of the average emissions of the grid a year ago). And power prices were negative for most of the weekend. I imagine anyone on Octopus agile with an EV has been very happy.
