Power generation of the three thermal power stations was 2330 mw, NLC Chairman-cum-Managing Director B Surender Mohan today said.
The total capacity is 2490 mw.

All the three lignite mines at Neyveli were producing lignite as per target, he said, adding, surplus lignite has been stocked in the stocking yard for emergency needs.
NLC said the unions' demand that all long serving contract workmen be regularised as NLC employees immediately was contrary to the 12(3) settlements dated October 30, 2010 and June 3, 2012 entered into by the Contract Workmen Unions and also does not flow from the Supreme Court order under reference.
