Financial Metrics
LCOE is the average cost of generating each kWh over the project's life, including CAPEX, OPEX and the discount rate. It exists for comparison: if LCOE is below the host user's tariff or the spot price, the project has an economic edge.
For the investor: a low LCOE signals an efficient design and a sounder margin. It is one of the figures worth looking for on the project sheet.
