How it works

Wind annual value and simple payback

Value actual self-used and exported generation at distinct usable rates, then subtract recurring costs. Keep upfront incentives, recurring receipts and installed costs explicit; zero net benefit has no finite simple payback.

Annual net benefit = self-used kWh × avoided-import rate + exported kWh × usable export rate + other annual receipts − recurring costs; payback = net upfront outlay / positive annual net benefit.

Wind dated cash flows and NPV

Compare all entered annual wind-project cash flows, including usable electricity benefits, operating costs and replacements. Inspect NPV, first recovery and recovery retained through the whole horizon.

Year net flow = avoided imports + export receipts + other receipts − operating costs − replacements − other costs; NPV = −net initial outlay + Σ year net flow/(1 + discount rate)^year.
