  • Wave Energy: Development Status

    Costs and Cost ProjectionsUtility Generator Commercial Plan after Tax Incentives (300,000 mWhr/yr)

    Total Plant Investment - $238-279MCost of Energy 9.2 11.2 cents/kWh

    Levelized cost of wave-generated electricity is less than wind-generated electricity at any equal cumulative production volume under all cost estimating assumptions for the wave plant.
