The Ministry of Environment, Forest and Climate Change (MoEF&CC), has published draft revised norms on emissions from generators. These would be common for all fuels and upcoming fuels.
This would become effective July 2023.
Currently, there is a variety of emission standards for generator sets. These are based on different fuel gasoline, diesel, dedicated CNG and dedicated LPG, dualfuels & bi-fuels. “The revised standards are a single standard covering all available fuels and upcoming fuels viz producer gas, hydrogen gas, etc,” the proposal has said.
The draft notification was sent late Friday night.
The India Genset Emission Standard-IV+, which is applicable to gen-sets of two types, mentions the limits for NO (Oxides Of Nitrogen); HC [Hydrocarbon]; CO (Carbon Monoxide); and PM (Particulate Matter), as well as for CI (Compression Ignition and PI (Positive Ignition).
“We had an experts’ group formed to study this and then we also had the findings peer-reviewed and only then issued this draft notification,” said a senior scientist from the Ministry.
India is facing increasing air pollution. Generators that burn different fuels are one of the main sources. The Centre has taken a number regulatory measures to prevent, control, or reduce air pollution in India. With the availability of cleaner fuels such as BS-VI, the regulation on emission from DG sets is required to be improvised, the Ministry’s draft notification said.
Certifications would be based on the type of engine and certified agencies would be established.
The new emission limits applicable to new engines of up to 800 kW that are used for power generation set will be in force on July 1, 2023. Additionally, the draft will include transition provisions for Gensets as well as Genset Engines manufactured in accordance with Central Pollution Control Board-II norms.
