Wow, what's your price per kWH and what (rough) location?

  8760 hours = 1 year So... a 1 Watt device running 24x7 = 8.760 kWh billed at about $0.40/kWh [includes both generation and delivery and normal for NE USA - ain't deregulation great?!] ~ $3.50 per year. In order to get to $1.00, total cost per kWh must be about $0.114 ...

    Thanks, turns out I've had the wrong maths for this in my head for years!

  me1010 beat me to it, I didn't know that HN keeps people from posting too often. It imposes a timeout! I know now! Anyway, here's my post, same cost info as he has. But I also had a discussion of power in various areas: Portland Oregon metro area. Unfortunately for pricing the utility is Portland General Electric. Some places in the area have "people's utility districts", i.e. publicly owned. Those get preferential pricing from the govt, i.e. Bonneville Power. And the price per kWH is of course variable like in most communities (e.g. because of lifeline pricing). Overall I'm paying about $0.12 per kWH. There are 24x30x12 hours in a year = 8640 hours. Therefore a kilowatt costs $1037 per year. Approximately. I'm relatively happy, all things considered. It would suck to live in the People's Republic of California. My understanding is that peak pricing in some communities there could be 3x or more than what I'm paying.

    Aha. The storage decisions I make will have to be a bit different given that I'm paying around $0.31 per kWH. Thanks for that.
