Citing a surge in costs on account of change in the rate of Goods and Services Tax (GST), Tata Power Renewable Energy Limited (TPREL) had approached the Maharashtra Electricity Regulatory Commission (MERC) demanding compensation. In its order, MERC has, however, dismissed the petition filed by TPREL. The developer had sought compensation on the grounds that the increase in GST fell under the ‘Change in Law’ clause in the power purchase agreement (PPA).
