TN grid curtailment wastes 70 million units of renewable energy

CHENNAI: Amid increasing push by centre and state governments to produce more renewable energy (RE), grid curtailment has led to 70 million units of renewable power not being evacuated by the Tamil Nadu Transmission Corporation (Tantransco) over the past one week, power producers said.

State authorities said decrease in power demand due to change in weather led to the drop in evacuating renewable power.

According to REPA (Renewable Energy Producers Association), the TN Load Dispatch Centre, which is the grid manager and Tantransco have been reducing power intake by curtailing the grid for three to five hours a day in substations, including Theni, Surandai, Veeranam and Aralvaimozhi, in the last one week to 10 days. This has resulted in eight to 10 million units of generated renewable energy going to waste every day, REPA said.
