Environment Department proposes common emission standards for generator sets, Energy News, ET EnergyWorld

New Delhi: The Ministry of Environment, Forestry and Climate Change (MoEF&CC) has notified draft revised standards for generator emissions which would be common to all fuels and even future fuels. This would be effective from July 2023.

Currently, there are three different emission standards for gensets based on different fuels gasoline, diesel and dedicated CNG, dedicated LPG, dual fuel and dual fuel. “The revised standards are a single standard covering all available fuels and future fuels, i.e. production gas, hydrogen gas, etc.,” the proposal states.

The draft notification was released late Friday evening.

Indian Genset Emission Standards-IV+ given for gensets in two categories mention NO (oxides of nitrogen) limits; HC (Hydrocarbon); CO (carbon monoxide); PM (Particulate Matter) and also for CI (Compression Ignition) and PI (Positive Ignition).

“We formed a group of experts to study this and then we also had the results peer reviewed and only then did we publish this draft notification,” said a senior scientist at the ministry.

Air pollution is a growing threat across India and among point sources of emissions, generators using different fuels are a significant source. The Center has also taken a number of regulatory measures for the prevention, control and reduction of air pollution in the country. With the availability of cleaner fuels such as BS VI, emissions regulations for DG sets need to be improvised, according to the ministry’s draft notice.

There would be certifications based on engine types and there would be authorized agencies for certifications.

Emission limits for new engines up to 800 kW used for generator sets will come into force from July 1, 2023, with the draft also mentioning transitional provisions for generator sets and generator set engines manufactured to the standards of the Central Pollution Control Board (CPCB-II). .
