A wind turbine rated at 250 KW costs $450,000 and has a swept (rotor) area of 1200 m2. It is installed at a location with year-round average power density available in the wind of 320 W/m2, and on average converts 25% of the energy into electricity. The electricity is sold to the grid at $0.039/KW-hr paid at the location of the turbine (i. e, no transmission costs). The project has a 20-year lifespan with a salvage value of $20,000 at the end of its life. The interest rate is 8%. Calculate the present value of this investment.
