I'm on a electricity tariff where the per kWh unit price changes every 30 minutes, you're basically being charged at market rate or thereabouts, the prices for the next 28 hours are announced at 4pm every day.
Generally the prices betwen 4pm-7pm are expensive and the rest of the time it's cheaper - although with current world events things have gotten a little spicy lately.
On really windy days you definitely get to see the benefit where prices drop to zero or even negative, which is great if you have an EV or something to dump lots of power into. Looking at todays prices they're like 1-3p p/kWh!
But that doesn't last, as the wind dies things start to get back to normal.
The key with the tariff though is to just play the averages and generally avoid high power usage during the peak periods. My average for the last 2 years was around 30% cheaper (p/year) than what I would have paid if I was on a normal energy tariff.
It will be interesting to see whether that trend continues, especially with the state the world has suddenly been thrown into.
