In a Business Standard article, though solar tariff rates have hit an all time low in the REWA bidding, the future of solar projects seems bleak as there are no new tenders from the big states. Tenders from SECI and NTPC are facing delays and those from Rajasthan and Andhra Pradesh are getting downsized. In states like Rajasthan, Andhra Pradesh and Karnataka, the project biddings have been postponed. For the year 2016-17, only 10 GW of solar power has been awarded out of which 30% has been by the states and the rest has been from SECI and NTPC.
A recent article in the Business Standard highlighted the solar power tariff which has hit a new low. In a Solar Energy Corporation of India’s auction of rooftop solar power projects, Gurgaon-based Amplus Energy Solutions quoted a tariff of Rs. 3 /unit defeating the previous low of Rs 4 /unit for a solar park in Rajasthan by a quarter. The rooftop projects will be installed on buildings of NGOs, educational institutes, hospitals, trusts and not for profit companies in these states.
The lowest tariff quote for these projects is same as average tariff offered by state-run generation utility NTPC for power from its coal-fired plants and nearly half of tariffs charged by some private power producers.
Till now, a solar project at Badhla in Rajasthan held the record for the lowest tariff at Rs 4 per unit in the solar park category. The lowest tariff before that was Rs 4.34 per unit, quoted by Fortum India in January.
Rajasthan Electricity Regulatory Commission (RERC) recently proposed a levelized tariff under a draft regulation (RERC Terms & Conditions for Determination of Tariff for Renewable Energy Sources Regulations, 2016) issued for Solar power generators of the state.
The graph below depicts the change in the tariff from the past year:
RERC has invited the comments and suggestions by 13th September 2016 on the same. The tariff proposed for FY 16-17 is much lower than the tariff of previous year in case of both Solar PV and Rooftop Solar PV, It can be said that the reason behind the reduction in the tariff of Solar PV is because of decreasing prices of Solar PV cells.

Madhya Pradesh Electricity Regulatory Commission recently released its tariff order for energy procured from solar power based projects for the control period from 31st March 2016 to 31st 2019. The tariff determined by the Commission in this will be applicable to the following Projects located in the State of Madhya Pradesh and selling electricity to the distribution licensees within Madhya Pradesh only:-
(a) Solar PV Power Plants
(b) Solar Thermal Power Plants
The Commission came out; vide its proposal for categorization of solar PV and thermal projects as well as for fixing the norms for technological specific parameters.
The Commission has fixed the normative capital costs inclusive of all components as well as taxes etc. for solar thermal and solar PV projects by keeping in line with the CERC benchmark capital cost of Rs. 12 Crore and 5.3crores per MW for 2016-17.

The Commission, in its Order dated 1st January, 2015 on BESCOM’s Review Petition noted that there was substantial reduction in the capital cost of grid connected solar power plants.
Therefore, it examined the need to curtail the present control period and re-determine the tariff in separate proceedings, in the midcourse. The Commission, in modification of its Order dated 10th October, 2013, decided that the norms and tariff determined in this Order shall be applicable to all new grid connected MW scale solar PV and solar thermal power plants, entering into Power Purchase Agreement (PPA) on or after 1st September, 2015 to 31st March, 2018.
For determining the tariff of the same, comments/suggestion of the stakeholders on the capital cost, operational and financial parameters were invited. The table below depicts the proposed capital costs for solar PV projects and solar thermal projects before and after the midcourse re-determination of tariff.
Based on the comments and suggestions received from various stakeholders on the abstract of the parameters considered for determination of the tariff, the commission approved the following tariff on 30th July 2015 which differs from the earlier determined tariff.
