Maruti Suzuki to Complete Waste-Heat Project by March

Maruti Suzuki India Ltd., India’s biggest carmaker, expects to complete its second project that generates power from hot air emitted by its factories by March.

The project at the company’s Manesar factory will use heated exhaust gases, previously discharged into the air, to run a 37.5-megawatt steam turbine, according to an e-mailed response to questions.

Maruti Suzuki runs its own fossil-fuel power plants to avoid disruptions caused by the nation’s erratic electricity supply. The exhaust from that captive generation is as hot as 450 degrees Celsius (842 degrees Fahrenheit) and can be recovered to produce energy.

The company completed its first waste-heat recovery project last year. The 1.5 billion rupee ($24 million), 17.5-megawatt installation at its Gurgaon plant is expected to save 41,000 metric tons of carbon dioxide emissions annually, according to documents from the United Nations’ Clean Development Mechanism, which awards carbon credits.
