NTPC, Delhi Jal Board partner on sludge project

NTPC, India’s largest integrated energy company, has partnered with Delhi Jal Board (DJB), the government agency responsible for the supply of potable water, to convert sludge from DJB’s sewage treatment plants into renewable energy.

The torrefied waste sludge was fired from NTPC’s unit 4 boiler at Dadri. This green solution offers an innovative way to convert sewage sludge into energy while reducing carbon emissions.

In Delhi National Capital Region alone, sewage treatment plants produce up to 800 MT of sludge per day. The disposal of this sludge is a major challenge as it contributes to environmental pollution. It also poses a health risk to those living in the area.

NTPC is taking steps to make its energy portfolio greener and plans to have 60 GW capacity through renewable energy sources by 2032. The company’s total installed capacity is 68,881 MW, with 23 coal-based, 7 gas-based, 1 hydro, and 19 renewable energy projects.
