Energy Saving

My electricity is supplied by EON. They've been trying to get customers to shift their power consumption to, presumably, times when there is less demand - usually mid-afternoon 1-3pm or 2-4pm. They set you a target of increasing your power consumption and pay you for each kilowatt that you use over your normal consumption. The payments vary - today it was 25p kWh.
Today -
"The next #PowerUp event will be on 28 April 2026 from 2:00PM to 4:00PM. Your target is to use 1% more electricity than you usually would during this time.
We're not saying use more energy for the sake of it, it's all about shifting your energy use to a different time. So, you could get some of your high energy chores done, like doing the laundry or using your dishwasher.
If you hit your target, we'll give you £0.25 credit for every extra kWh of electricity you use."
Tomorrow - they're paying 30p.
I've considered these offers to be a bit too much trouble to bother. I only use the washing machine on sunny days - and do a load early in the morning so that it can dry by the evening.. I'm not much of a cook and I don't have an oven so I won't be baking cakes!
However, today, I realised that this offer gives, effectively, free electricity since I pay 18.71 a kWh - so, I'm going to try to make use of it.
I did a load of washing after 2pm and pegged it out under cover in the log store. - the weather wasn't good enough to put it outside.
I also boiled the kettle several times and filled a couple of flasks - enough to not need to use the kettle again tonight.

If you have any bright ideas for energy shifting tomorrow afternoon, please let me know.
