Generic Renewable Energy Tariff for FY 2021-22 under MERC (RE Tariff)

Generic Renewable Energy Tariff for FY 2021-22 under MERC (Renewable Energy Tariff) Regulations, 2019 (Suo Motu Order).

As stated earlier, none of the Distribution Licensees in the State has discovered tariff for procurement of energy from Rooftop PV through competitive bidding. The Commission notes that under Net-metering arrangement it is expected that consumer will install Rooftop PV for self-consumption only and would not have a planned surplus except for only a negligible unintended quantum, more due to climatic/weather factors.

Provision of annual banking allowed under Net-metering arrangement would further reduce such surplus available at the end of financial year. Such surplus power procured by Distribution Licensee is used for meeting its Solar RPO. Distribution Licensees have option of meeting their Solar RPO by procuring energy from grid scale solar PV projects and Licensees in the State have already been exercising such option. Hence, the Commission deems it fit to use latest tariff rate discovered for Grid Scale Solar project as a Generic Tariff for procurement of surplus energy from Rooftop PV projects. The Commission notes that in its Order dated 15 May 2020 in Case No. 81 of 2020 has adopted rate of Rs. 2.90/kWh for Grid Scale Solar Project.

Accordingly, Order in Case No. 29 of 2021 Page 6 of 7 the Commission hereby notifies Rs. 2.90/kWh as a Generic Tariff rate for procurement of surplus power at the end of Financial year from Rooftop-PV projects for FY 2021-22. It is mandatory for Distribution Licensees to procure such surplus power at the end of financial year which would in any case be counted towards meeting their Solar RPO.

Thus, while determining APPC, procurement from renewable energy sources and liquid fuel sources needs to be excluded. Accordingly, Distribution Licensee wise APPC for FY 2021- 22 is given below:

Provisional Variable charges of Biomass and Non-fossil fuel-based Co-generation Projects:

For the reasons stated in para 7, 8 and 9 above, the Commission is extending existing variable charges for Biomass and Non-fossil fuel-based Co-generation Projects as determined under RE Tariff Order dated 30 April 2019 in Case No. 52 of 2019 on provisional basis till the Commission determines variable cost for these projects based on fuel cost arrived through the Study being conducted by TERI. Variable Charges approved in RE Tariff Order dated 30 April
2019 are as follows:

Tariff rates notified in this Order shall be applicable for FY 2021-22 with effect from 1 April 2021.
