Why India’s Deadly Coal-Power Plants Will Continue Polluting

Update: 2017-12-21 00:30 GMT

New Delhi: Over five years to 2017, thermal power plants--among India’s chief polluters--pushed nationwide levels of sulphur dioxide (SO2), a toxic gas, by 32% and fine particles called PM 2.5 by 34%.

 

Despite agreeing to a two-year compliance period, these plants ignored a December 7, 2017, deadline and a 2015 law promulgated by the environment ministry to clean up. Now the same ministry is arguing that so many power plants cannot go offline and is urging the Supreme Court, which will hear the case on February 1, 2018, to push the deadline to 2022.

 

If the power industry had implemented the new norms, emissions from thermal power plants could have fallen by 70-85%, said a 2017 brief released by a group of citizens, volunteers, and activists from non-profits Greenpeace India, Help Delhi Breathe, My Right to Breathe, Jhatkaa, The Climate Agenda and URJA.

 

More than 300 thermal plants nationwide were to install scrubbers and filters after the environment ministry notified new air pollution regulations in December 2015 under the Environment Protection Act, 2015.

 

A government affidavit filed before the Supreme Court in November 2017 argued that all units could not be taken offline to retrofit equipment because power supply from thermal plants--which supply 80% of India’s electricity--could not be interrupted.

 

“… An (sic) earliest practical feasible plan extending up to December 2022 has been prepared,” the affidavit said.

Under the 2015 rules, thermal power plants were supposed to install three pieces of technology: Electrostatic precipitators (ESPs) to curb particulate matter, flue gas desulphurisation (FGD) to minimise SO2 and mercury, and selective catalytic converters (SCRs) and selective non-catalytic converters (SNCRs) to reduce NOx. The RTI replies show that most plants are still studying the feasibility of FGDs and have not installed catalytic converters.

 

“It is disappointing to note that power plants have not taken sufficient action in the past two years and are now requesting even more time to install the necessary emission reduction technology,” Avijit Michael, executive director, Jhatkaa, said in a statement. The ministry of environment must penalise defaulters to demonstrate that it considers the health of Indians a priority, he added.

 

Retrofitting plants will take time, make power costlier: Industry

 

In its reply to the RTI query, the National Thermal Power Corporation (NTPC) said it could not shut down its more than 20 power plants, which collectively produce almost a fourth of India’s electricity, to install catalytic converters and FGDs because that would “plunge the country into darkness”.

 

“Didn’t it occur to them (NTPC) two years ago to shut down one unit of one plant at a time to carry out the retrofitting?” asked the brief from the group of nonprofits previously mentioned. “Wasn’t that the logical course of action?”

 

It would cost $38 billion (Rs 2.4 lakh crore) to clean up India’s coal-fired power plants, said New Delhi-based Association of Power Producers, and electricity would become costlier.

 

However, the Centre for Science and Environment, a think tank and advocacy, in a 2016 study estimated clean-up costs would lead to an increase of less than 3% annually in power tariffs over the next three years.

 

Environment ministry secretary CK Misra recently justified the delay.

 

“The ministry stands by its notification. However, we need to be practical. We can't switch to these technologies overnight,” Misra was quoted as saying in the News18 on December 10, 2017. “Conversations are on with them (thermal power plants) to do so within a reasonable frame of time.”

 

The two years compliance time, which the ministry now deems as being too short, was decided after many meetings between the environment  ministry, the power ministry, the power industry and the Central Pollution Control Board.

 

Set up a committee to oversee compliance: Petition

 

The environment ministry is also fighting a case before the National Green Tribunal (NGT) against Greenpeace India campaigner Sunil Dahiya, who has alleged that the ministry is not implementing the 2015 air pollution rules.

 

The NGT has asked the ministry for compliance status, Ritwick Dutta, an environment lawyer appearing for the petitioner Dahiya, told IndiaSpend. “We have demanded a committee to oversee the compliance,” said Dutta. “Plants not abiding by the new norms should be penalised under the Environment Protection Act.”
