The other week, it was not very windy but it was cold, so the energy price spiked pretty high (£1/kwh). Other times the energy price falls pretty low, and I regularly see it be negative for some hours of the night or rarely up until the afternoon.
Paired with a home battery it can be pretty effective, but I don't have one and instead I just work around it and use my electrical heating more when it's cheaper and rely on my insulation to last throughout when it gets more expensive during the day. I've also started cooking dinner later to get past the evening hump.
Just shifting some electricity usage around is a pretty solid tactic with dynamic pricing.
I'm currently paying wholesale + 0.49 c/kWh margin for my electricity and I'm averaging out to 6.67 c/kWh (incl. margin) in December. Wholesale average has been about 6.61 c/kWh. Add transfer and tax on top of that and it's around 0.13 €/kWh total.
I live in an apartment so the two big electricity-wasters are the dishwasher and the washing machine. Delaying doing the laundry by a couple of days or running the dishwasher half a day later keeps the average much lower. And if you have an EV, just charge it during the night when wholesale prices get closer to 0€.
Here's my prices for tomorrow for those who are interested. They publish an API for this too which I have loaded into a spreadsheet for my own entertainment
