‘Upgrading India’s old power plants can offer ₹3,500 cr in savings’

Twesh Mishra Plant upgrades can help domestic power generation companies save nearly ₹3,500 crore a year, according to Andrew DeLeone, Managing Director of GE Power India Ltd.

The efficiency of a thermal power plant is defined as the ratio of the total energy produced as a per cent of heat energy generated by burning coal.
