Work parts d and e on page 2 and attach. A location on the US western plains has prevailing winds of 10 m/s sv s 20 m/s @ a height of 80 m, 60% of the time. A friend of yours invites you to join him in a business venture to build a 36 MW Wind Farm. (d) Make a plan drawing to scale, showing the 3MW WT's and the property lines. Use a spacing of 10D, with a distance of 5D from the outer WT's to the property line. Compute the required area in acres. (e) A federally guaranteed loan @ 2% interest is available for the necessary capital investment (the loan must be paid off in 10 years). The local utility guarantees to pay a wholesale rate of $0.05 per kWh. Allow 100 k$ per 3 MW unit annually for maintenance. The land can be leased from the federal government for $ 100 per acre annually. Allow 100 k$ per 3 MW unit annually for maintenance. It takes one year to construct the Wind Farm (Year 1), over which the WF income is zero. The first loan payment is due at the end of Year 2; the last loan payment is due at the end of Year 10; payments are made annually. Determine the loan requested, and the annual loan payments. Is this a good investment? ELEC 3600.
