According to reports, the Indian Wind Power Association (IWPA) has written to the Tamil Nadu Electricity Regulatory Commission (TNERC) asking them not to permit further purchase of energy from other states during windy months as enough quantum of wind energy is already available in Tamil Nadu during windy months. This is in response to the petition filed before the TNERC on 13 September 2013 by the Tamil Nadu Generation and Distribution Corporation (Tangedco) requesting permission to procure additional 2122 MW during windy months.
“For the past 4 months, from June 2013, misusing the permission granted to buy 1208 MW of outside power, Tangedco is buying outside costly thermal power even during the windy months of May to September by backing down wind mills 8 to 22 hours daily and refusing to give “must run” status to wind mills calling it infirm power,” a statement from IWPA said. However, during the year 2012 wind power was fully evacuated to the extent of 12,000 million units during May to September even though wind energy was still called infirm power, the statement said
Wind Power constituted 16.5% of total energy in Tamil Nadu in 2012 from installation of 7195 MW capacity installed at a cost of Rs 42,000 crore. Further, at a price averaging Rs 3.05 per unit wind energy is the cheapest form of pollution free energy available within the State as distributed generation avoiding much of transmission losses, IWPA said.
“Refusing to provide “must run” status to wind energy and not accepting the energy by backing down wind mills results in ruining the financial viability of investment in Tamil Nadu. The evacuation of renewable power will go down to less than 8% in 2013 -14 as against the norms of 14% laid down by the TNERC,” the chairman of IWPA, K Kasthurirangaian said.
