Gujarat Urja Vikas Nigam Limited (GUVNL) has approached the CERC to withdraw higher tariff support to Adani Power’s imported coal-based 4,620 MW Mundra TPP, stating breach of terms of the relief package. The state utility has sought a refund and interest on the excess tariff paid to Adani Power due to fuel cost pass-through. In its order dated April 12, 2019, the CERC approved the higher tariff by making provisions through new supplementary PPAs between Adani Power and GUVNL.
