JOIN USWith an aim to bring the water utility’s electricity bill down by Rs 20 crore annually, biogas from the Delhi Jal Board’s sewage treatment plant in Kondli is now being used to generate power for the city.
About 45 million gallons per day (MGD) sewage treatment plant was providing biogas for the power plant, which is currently producing 10,000 killowatt-hour per day, said the DJB on Sunday.
Officials said the electricity generation will increase in the coming days.
The DJB had previously commissioned biogas power plants in Okhla and Rithala sewage treatment plants.
The Okhla plant is generating 12,000 kWh per day and the Rithala produces 20,000 kWH per day.
“Presently, 30 to 35 per cent of the power demand of these plants is being met from the electricity generated in house. This is also reducing the dependency on power supply from discoms,” it added.
Officials said that the plan is to set up biogas-based power plants in all DJB sewage treatment plants.
New plants
New treatment plants will be designed to include power generation facilities.
Soon, electricity generation will start at the sewage treatment plants at Pappan Kalan, Nilothi, Yamuna Vihar and Delhi Gate.
The DJB has set a target of 70,000 kWh per day of power generation through its gas-based plants by the end of 2015.
Officials say that the flaring of biogas at some plants is wasting a potential source of clean energy.
The DJB has prepared plans to trap the gas and transport it to the nearest power plant to generate electricity in the next two months.
