In europe that situation will be wildly different. Here in germany you won't get under 0.50$/kWh (edit: more like .30 now) so it's more like 500 to 800 hours
Edit 2: wow, thanks for the hint! I just halved my prices by switching
Those were last year's prices during the height of the energy crisis. I was paying 0.60€/kWh last year (new contract). I renegotiated this year and got it lowered to about 0.27€/kWh.
I switched to a half hourly tracker earlier this year. So it's like 10-15p/kWh (and sometimes as low as negative so they pay you to use the electricity) and jumping to 30-40p between 4pm and 7pm.
As someone working from home with pretty much constant electricity use all day, it's saved me tons.
I live in a rural part of the US (Which is honestly most of it) and electricity runs about $0.12/kWh. Ya'lls prices are mind blowing. Especially since we heat with electric heat pumps. At those rates my electric bill would be about $625/mo instead of $250/mo.
