"The project will generate approximately $2 million worth of renewable energy capacity over the 20-year PPA period, enough electricity for more than 150 homes in Portland."
100kW * 24 * 365.25 * 20 = 17532000 kWh over it's lifetime.
$2,000,000.00/17532000 ~= $0.11/kWh.
Not bad for renewable power, absolutely terrible for hydroelectric ($0.01-0.03 / kWh on average).
- therealdrag0 12y agoAnd that's assuming full capacity (100kW)... That's too bad. But I don't quite understand what you're doing with the $. You're taking how much it'll generate in kWh vs how much they say it'll generate in worth of energy and getting a $/kWh. But isn't the $kWh just determined by the market? Why not: 2,000,000 / .02 (your number) = 66,666,666 kWh over the lifetime of the 'project', not individual units, which has 4 turbines (this is a similar value to yours x4).
- pstrateman 12y agoYou're right, that's not a fair comparison. (I'd guess the real cost of power from this is >$1.00/kWh btw since it will almost certainly not last 20 years...)
