Instead of signing MoU, PPA, submitting performance bank guarantee etc for 25 years or participating in cut throat bidding process (project is viable only to module manufacturers for the rate it can be achieved), I suggest to develop the solar project under REC Mechanism, as for selling the power through average exchange rate and realizing the mean value of REC rate for first five years and half of the floor price for next 5 years, yields levellised rate of Rs.10.536*. [Solar Tariff in Gujarat: Rs. 9.28 for project commissioned up to 2013, Rs. 8.63 for project commissioned up to 2014 and Rs. 8.03 for project commissioned up to 2015].
Even if REC floor price is reduced by half for next 5 years and NIL thereafter, developing the project under REC and selling the power through Energy Exchange, would yield rate of Rs.9.647 which is more than maximum rate of NVVN against cost of generation not more than Rs.6.50. [NVVN is the nodal agency of NTPC for procuring solar power to meet their REC requirement. In the 1st phase NVVN finalized bid for 150 MW Solar Projects and in latest bid for 350 MW Solar Projects. In the latest NVVN bid the price offer for solar power projects were minimum Rs.7.49 and maximum Rs.9.44]
