Response to the following :
For me to better understand the capital and operation and maintenance (O&M) costs involved in installing 2 possible wind farms and the operating lifetimes, please provide the following information;
A) Calculate the predicted annual output, in MWh per year, for each site A & B shown in table 1:
B) In both cases, the capital cost is to be repaid over the estimated lifetime, at a discount rate of 10%
The annual capital repayment for site A = £110 and Site B = £117
Annual operating and maintenance (O&M) costs are in both cases equal to the given percentages of the total capital cost. Add these to give the total annual cost for each turbine.
