Last Saturday, the grid was so full of clean power it started paying people to use electricity. β‘
For nine hours straight, wholesale prices went negative right across all 14 UK regions β bottoming out at -8.9p a unit at midday. Then by tea time it flipped to over 20p.
Here's the catch: most homes can't touch that cheap window. You're out, or barely using anything between 7am and 4pm β then you pay full whack at 8pm when the kettle, oven and telly all come on at once.
Solar panels and a home battery flip that on its head. You bank the free daytime energy and run the whole house on it through the expensive evening peak. On a day like Saturday, that's money straight off your bill.
We pulled the real region-by-region figures β including right here in the North East β and broke down exactly how to cash in. π
Were you on Octopus Agile or EDF FreePhase on Saturday? Did you catch the negative prices? π
