The Appellate Tribunal for Electricity overturned orders by the Tamil Nadu Electricity Regulatory Commission (TNERC) that had imposed increased charges on wind power producers. The present appeal comprises a batch of appeals filed by the Tamil Nadu Spinning Mills and the Indian Wind Power Association, challenging the orders passed by TNERC in 2016. The issues raised were whether TNERC was justified in directing that transmission and wheeling charges be levied based on installed capacity rather than actual units generated and whether increasing the banking charges from 5% to 10% was warranted.
