The 500 MW Unit-4 of NTPC Simhadri Super Thermal Project at Parawada near here has started commercial operations – six months after it went on stream -- even as the company is set to breathe easy with improvement in coal supply position.

The company, which has 500x4 MW units as part of Stage-I and II of the Rs.10,000-crore project, is set to overcome coal shortage with the State government agreeing to supply 7,000 tonnes per day in addition to the early availability of 3,500 tonnes from Singareni Collieries Company Limited (SCCL).
