The state-run National Thermal Power Corporation (NTPC), which proposes to increase its generation capacity to 50,000 MW by 2012 from the present level of 27,404 MW, has firmed up plans to enter into captive power generation and retail distribution in the upcoming greenfield special economic zones (SEZs). NTPC's move is crucial especially when the centre has so far notified as many as 195 SEZs across the country under the SEZ Act, 2005.
