Solar Power Levilised Tariff LCOE pf Rs. 2.44 per KWh
On 10th May , the lowest bidder for the solar park in Rajasthan had quoted Rs 2.62 per unit for Bhadla Solar Park phase IV and after two days, on Friday May 12th, ACME Solar Holdings quoted lowest solar tariff at Rs.2.44/kWh for 200 MW followed by Japan's SBG Cleantech One at Rs.2.45/kWh for remaining 300MW during an auction carried out by Solar Energy Corporation of India Limited (SECI) for 500 MW capacity in Bhadla Phase-III Solar Park, Rajasthan. The solar park is being set up by Saurya Urja Company of Rajasthan Ltd, a joint venture between Rajasthan and IL&FS Energy Development Company Ltd. Respectful players like Acme, SBG, Vinnet Mittals – Avada, Hero, Renew Power, Shapporji Palonji etc participated in the bid and it is really heartening and charismatic to see that LCOE of Rs. 2.44 per kWh is not only a finance game but a big game of technology as well.
The projects are likely to be completed in about 12-13 months.
The quoted tariff is fixed for 25 years with no escalation and the bidders have sought no VGF (viability gap funding) from the government.
The entire solar power will be consumed in Rajasthan, and power sale agreement with the state distribution companies is already tied up.
The developers are responsible to connect to the pooling sub-station of solar park. The developers will be paying solar park charges of Rs 45.2 lakh per megawatt towards land, connectivity (from pooling substation to state network) and other infrastructural facilities.

Marginal cost of electricity and Grid Parity-
Marginal cost of electricity-Marginal cost of electricity-
Solar generation is cheaper at the margin, and therefore has achieved grid parity in this location or region.
(i) Using Grid parity, LCOE can be compared with the marginal cost of electricity offset from the grid
(ii) On Nov 2015, two companies (SunEdison and SB Energy) had lowest bid of Rs. 4.63/kWh in India to win several 100 MW of solar in reverse auctions, and at that point of time it was rightly envisaged by the solar think tank that "we are very close to grid parity in India at both the wholesale and retail levels"
(iii) After the recent bid of ACME Solar Holdings and Japan's SBG Cleantech, during May 2017, the grid parity price in markets like India during Nov-2015 was Rs.5.8 - 7.5 at the retail level , and around Rs.3-4.5/kWh at wholesale.
