State-run power giant NTPC has raised its installed generation capacity target from 130 GW to 149 GW by 2032 and 244 GW by 2037, a senior official said. This assumes significance in view of India's rising per capita demand, which is estimated to increase from around 1,500 Kwh at present to 4,680 Kwh by 2047, when the nation will be celebrating 100 years of Independence.
