SECI as nodal agency of Ministry Of New And Renewable Energy (MNRE), has floated 400MW request for selection (RfS) for 400MW hybrid solar power purchase on Oct 2019 from hybrid solar developer. Accordingly, after selecting successful bidder SECI signed PPA with the hybrid plant developer.

In view of the Ministry Of Power (MoP) order of long term growth trajectory on renewable purchase obligation (RPO) of different states, WBSEDCL proposed to buy 701.6 MU solar wind hybrid power based on CUF of 80.05%. After analysing it was observed that WBSEDCL will lag far behind of the scheduled RPO, since they could only achieve 1.15% of RPO for the duration of 01.04.2021 to 31.12.2021.  In view of the above context, WBSEDCL agreed to purchase 100MW RTC hybrid power from SECI acting as intermediary buyer. Thus commission observed that the proposed 100MW RTC hybrid power procurement by WBSEDCL will improve the state’s RPO compliance further.

Commission’s Analysis & Decision :

In view of the above context, the commission approved PSA agreement with tariff of 2.90INR/Kwh for first year with yearly escalation of 3% till 15 years and no further escalation after 15 years. Also trading margin of 0.07 INR/Kwh will be applicable for the entire 25 years period of agreement. Commission also observed that the RTC power tariff will be much cheaper than renewable price of power exchange at the rate of 5.29 INR/Kwh for FY 2021-22 . As the power will be procured through ISTS line, WBSEDCL will not be obliged to pay any ISTS transmission charges, in line with Gov of India’s waiver of ISTS transmission charges for the project commissioned before 30.06.2025. The commission directed WBSEDCL to adhere provisions of intra state ABT , state grid code etc.
