Bangalore-based Power System Operation Corporation Ltd, a wholly owned subsidiary of Power Grid Corporation of India supervising the Southern regional grid, has given the instruction in this regard, an official release said here.
It has asked Tamil Nadu, Kerala, Karnataka, Andhra Pradesh and Puducherry to reduce the load, maintain the grid frequency above 49.5 Hz, grid security and discipline, the release from Tamil Nadu Electricity Board said today.
"In accordance with the Indian Electricity Grid Code 2010, the grid discipline is strictly maintained by Tamil Nadu despite the failure of South West monsoon, infirm nature of wind-power and frequent outages of central generating stations," it said.
The release added that grid discipline was being "strictly maintained" by Tamil Nadu to avoid grid power collapse.
