Tata Power Solar

Recently Maharashtra Electricity Regulatory Commission (MERC) approved compensation to Tata Power Renewable Energy Ltd (TPREL) on account of importing solar inverter and solar modules for their 150MW Solar Power Plant.


On August 2019, Tata Power Company Ltd – Distribution (TPC-D) issued request for selection (RfS) for procurement of 150MW solar power for their renewable purchase obligation (RPO). After selection of TPREL as lowest bidder, letter of award (LoA) was signed between TPC-D & TPREL. On 3th Jan 2020, TPREL entered into a PPA with TPC-D for supply of 150MW solar power to TPC-D at a tariff of Rs.2.83/Kwh for 25 years. Further on 23.02.2020, TPREL entered into a supply contract with Tata Power Solar System Ltd (TPSSL) responsible for all EPC works. As per the PPA, the schedule commissioning date (SCOD) was 18 month from the date of PPA issuance i.e. 3rd July, 2021.


Accordingly, TPSSL ordered imported solar inverter and solar module at last stage of schedule commissioning date. In the mean time, on 01.02.2021, Ministry of Finance revised basic custom duty (BCD) on inverter to 20% from 5%. In addition, on 29th July 2020, Ministry of Finance extended safe guard duty (SGD) on imported solar module at the rate of 14.9% for the period of 30th July 2020 to 29th July 2021.
