India is planning to invest over Rs 74,000 crore within the next five years to improve energy efficiency and cut carbon emissions from its power sector. Coal-based power generation plants account for around 60 per cent of India’s total carbon emissions.

The country’s biggest power producer NTPC Ltd has already decided to invest Rs 0.5-1 crore per megawatt (Mw) of capacity to renovate and modernise its coal-based capacity, especially of plants built before the nineties, said its Chairman and Managing Director R S Sharma.

India emits around 540 million tonne of CO2 annually from the current coal-based capacity of 81,355 Mw. Overall emission levels may, however, go up with the addition of more coal-based capacity.

NTPC has chalked out a four-pronged approach besides earmarking 0.5 per cent of its annual profit, totalling roughly Rs 40 crore, towards its climate change mission.

“We are using ultra supercritical technology, working on Integrated Gasification Combined Cycle (IGCC), diversifying into renewables and working on improving efficiency of existing power plants,” said Sharma.
