It also termed the decision as "wrong" from environmental and economic point of view.
The coal-based Badarpur power plant will reopen on March 15, the Supreme Court appointed Environment Pollution Control Authority (EPCA) had earlier said while lifting a raft of measures implemented under the 'severe' air category of the graded response plan.
"The news (about reopening of the power plant) is a big setback to the efforts and progress made towards reducing public health crisis associated with air pollution," Sunil Dahiya, campaigner of Greenpeace India said.
Sources said NTPC was awaiting clearance from Delhi Pollution Control Committee to start the plant.
He highlighted the power plant's polluting nature and the annual generation target of 2017-18 by Central Electricity Authority (CEA) and the actual generation by the power plant which points towards "in-efficient" utilisation or functioning of the plant.
"It is wiser to use power from green and less polluting sources rather that from pollution guzzlers," he said.
The Greenpeace India campaigner said power from Badarpur station is much more costlier than the rate at which power is available from central grid and therefore purchasing power from central grid makes sense from economic perspective.
Dahiya said it "does not make any sense" to restart the polluting power station and run it at a Power Load Factor (PLF) which is not even economically viable.
problem the country is facing with respect to the increasing cost, underutilisation and high pollution from coal-based power generation.
To regulate the emissions from Thermal Power Plants (TPPs), the government in 2015 came up with progressive rules for old and new TPPs to reduce the impact on public health.
"Unfortunately, there is hardly any progress in implementation of the rules from thermal power producers and the Environment Ministry. The nodal agency has shown little interest in enforcing its own rules," Dahiya said.
A recent study by IIT Kanpur clearly articulated the need to reduce emissions from thermal power plants to as far as 300 km from Delhi to bring down air pollution in the city.
