According to reports, as part of the Smart City project, New Delhi Municipal Council (NDMC) plans to become energy-neutral—generating as much power as it consumes—by March 2016. After setting up small-scale waste-to-energy plants in its jurisdiction, the civic agency is planning to set up a big plant that will generate about 100MW power in a day.
The civic agency will soon float a tender for the project that is likely to come up in south Delhi.
“Our plan is to become energy-neutral by 2016. We plan to set up a waste-to-energy project which will generate 96MW in a day (4MW per hour) from 170 metric tonnes of waste. This will help us achieve our target of 200MW-plus power per day. We plan to set up two such plants,” said Jalaj Shrivastava, chairman, NDMC.
The civic agency’s daily consumption is 160MW, which increases to 200MW -250MW during peak season. NDMC is also setting up solar panels on its buildings to generate power as part of its Solar City project. It is working out a way for solar panels to be installed on private buildings.
“We hope to generate at least 10MW from the solar project, another 10MW or so from other waste-to-energy projects and 190MW from the two waste-to-energy plants which will use the entire waste generated in a day,” said Shrivastava.
Other officials said NDMC areas produce only about 250 metric tonnes of waste daily, so the civic agency will have to take waste from the municipal corporations to become energy- neutral.
The project has been approved by the Union urban development department that had sent a team to Indonesia to study similar projects. “This technology is called controlled pyrolysis. Such plants are there in Pentagon and White House. This will help us reduce our carbon footprint. In the long run, we hope to sell power generated using this technology. We will soon float tenders for the project,” said Shrivastava.
The biggest problem with waste-to-energy plants in Delhi is that they are unable meet energy targets as waste is not segregated at source and has a low calorific value. Explaining the technology, Shrivastava said, “In this, we don’t have to segregate waste. It will be done by the private concessionaire. The 170 metric tonnes of raw waste will first be reduced to 140 tonnes of usable waste, which will be used for energy generation”.
The civic agency has set up four small waste-to-energy plants in its parks. It is working on another project to set up similar plants in residential colonies.
