Although i do wonder if Octopus are making good money and buying these negative slots and then selling them to GO and Intelligent Etc. They probably have enough people signed up to theses TOU tariffs to be able to play the market. They were always against domestic batts playing the market.
You can see the day ahead wholesale prices here,
Just divide the £/MWh by 10 to get the pence per kWh.

Either we don't see the same reduction, or we weren't exposed to the worst of the peaks - thankfully
Its a bit of both, the government paid for the very large peaks as the unit rates were capped and regulated prices are based on a moving average so they lag coming down once they dropped below the capped value.

Thats why the tracker prices have been so good over the past year.

Great.
So using the Tracker tariff formula I multiply by 1.1913 and then add 10.5p to it. Gives me 19.618 p/kWh tomorrow. Nice.

It will probably drop a couple of pence from Saturday with all the wind and lower demand because of milder temeratures.
