At night, use 15kwh at $.12/kwh (offpeak rate) = $1.80
Let's say you do that for 30 days straight - one billing cycle.
end result is a credit of $78 waiting to be used.
BUT they throw in a $15 charge for the meter.
So you have to pay $15 for the month and have $78 to use toward electricity next month or the month after.
If after 12 months you have a net credit in $ amount, that gets zeroed out - but if you also have a net positive number of kwh, then you get $.04/kwh for those extra kwh.
So in this example it'd be $15 * 12 - 5kwh*12*$.04/kwh = $178.60 for the whole year.
(these numbers are made-up - but are close to reality.)
For Silicon Valley Electric, it's all $.11/kwh
So if you send 10kwh to the grid and use 10kwh back later it comes out as $0.
And if at the end of the year you have net positive kwh, I think they pay it out at about $.04/kwh.
