ECONOMICS OF 100 KWP SOLAR POWER PLANT SPECIFICATION: 100 Kwp SPV plantAWARD VALUE AS PER PO(including taxes): Rs 82,50,000.00VALUE OF AMC FOR 5 YEARS: Rs 2,50,000.00COST OF CAPITALISATION: Rs 56,00,000.00 (30% subsidy by MNRE)GUARANTEED OUTPUT FOR 1ST 5 YEARS: 100%GUARANTEED OUTPUT AT THE END OF 25TH YEAR: 80%CONSIDER A LIFE OF 25 YEARS.CAPACITY FACTOR:Generation during the two months of June-14 and July 14 is 16168 Kw HrCapacity factor= Annual Kwhr generation for each kw AC peak capacity/total hours in a year = [(916168 x 6)/100]/8760= 0.1107 = 11.07% LEVELIZED COST OF ENERGY:
LCOE= Total Life Cycle Cost/ Total Lifetime Energy Production
Total Life Cycle Cost= Investment cost + O&M costInvestment cost = Rs 5600000.00 + 10% simple interest for 25 years = Rs 1,96,00000.00 O&M cost= AMC cost for 5 years x [(1.5)0 + (1.5)1 +(1.5)2+(1.5)3+(1.5)4] = Rs 250000.00 (1 + 1.5 + 2.25 + 3.375 + 5.0625) (assuming 50 % increase in AMC after each 5 years) = Rs 250000.00 (13.1875) = Rs 3296875.00Total cost = Rs 22896875.00
Total Energy Production= 16168 Kwhr x 6 x [5 + 20 x 90%)] ( averaging out 80% for the next 20 years) = 16168 x 6 x 23 Kwhr= 2231194 KwhrLCOE= Rs 22896875 / 2231194 = Rs 10.26 per kwhr.
NB: During winter and summer months the energy production will increase. Hence actual CF and LCOE can be calculated more reasonably based on the data of complete one year.
