India relaxes the sulphur emissions rules for coal-fired power plants, reversing a decade-old mandate

A government order stated that India reversed its ten-year-old mandate for the installation of $30 billion in clean-air equipment and lowered sulphur emissions rules at most coal-fired plants.

In December, it was reported that the government is reviewing 2015 standards that require nearly 540 coal based power plants to install flue gas desulphurisation systems (FGD), which removes sulphur in the exhaust gases of the plants in phases beginning in 2027.

The Federal Environment Ministry issued a gazette notice late Friday that exempted from the 2015 mandate 79% of coal-fired plants outside of a 10-km radius (6 miles) of populated and pollution-prone cities.

In the notification, it was stated that the decision to install FGD in another 11% plants located near cities would be made on a case-by-case basis.

According to the new directive, the remaining 10% of coal-fired plants located closer to New Delhi or other cities with more than a million people will have to install desulphurisation equipment before December 2027.

About 50% of units have either ordered desulphurisation equipment or are installing it.

The notification of Friday did not mention any impact on competitiveness or cost recovery by these power plants.

The Central Pollution Control Board had conducted a detailed study of the increased "carbon dioxide emissions into the atmosphere as a result of control measures being implemented." (Reporting and editing by Sarita Chandanti Singh)
