Go Green is the new trend in the Power Industry, and genset is not an exception. With July 2023, India has now transitioned to CPCB IV+ emission standards for gensets up to 800kW from CPCB II. The updated regulations will broadly influence the entire generator set industry. The announcement of the CPCB IV+ emission standard in November 2022 reflects the Indian government’s dedication to reducing air pollution.

It will guide the industry towards a more sustainable trajectory and also support the development of new technologies and creative ideas. It’s important to highlight that India is now a sole economy aligning its emission standards with those of European and American economies.

Till now, Diesel generators, frequently employed to provide backup power in homes, businesses, and industries, have been recognized as a notable source of air pollution. These generators release harmful substances like nitrogen oxides (NOx), Sulphur dioxide (SO2), and particulate matter (PM), all of which can cause serious harm to both public health and the natural environment.

But now, with the introduction of the CPCB IV+ emission standard, the government’s strong commitment to tackling air pollution is clearly visible. According to the data, these regulations aim to achieve an impressive 90% decrease in particulate matter (PM) and harmful nitrogen oxide (NOx) concentrations in generator exhaust, surpassing the existing CPCB II standards.

These emission standards are designed to simplify the regulatory landscape by establishing a single benchmark for portable and fixed generators, regardless of fuel type, with a power output of up to 800 KW. This streamlined approach ensures clarity and compliance for the generator industry while maintaining strict emission reduction targets.

The CPCB IV+ guidelines will also spur significant technological evolution within the sector. Manufacturers will need to invest in advanced engines and emission control technologies, including electronic fuel systems, advanced after-treatment systems (ATS), and exhaust gas recirculation (EGR) systems, to meet these standards. These advancements will lead to more efficient fuel combustion, improved pollutant control, and enhanced fuel efficiency.

A notable advantage is the substantial enhancement in air quality, particularly in urban and industrial regions. Moreover, integrating advanced technologies will empower customers to monitor their real-time generator performance, resulting in better fuel efficiency and increased generator lifespan. The reduced fuel consumption by CPCB IV+ compliant generators will also translate to lower greenhouse gas (GHG) emissions, contributing to global efforts in addressing climate change.

The adoption of CPCB IV+ emission standards offers numerous advantages and opportunities for stakeholders within the generator industry and the broader economy. Technology providers and engine manufacturers have the chance to distinguish themselves by offering products equipped with sophisticated technology. Generator manufacturers can capitalize on this situation by providing specialized service packages to ensure continuous compliance with the CPCB IV+ norms. End-users, including residential and commercial properties and industrial entities like data centres, telecom facilities, and infrastructure projects, will experience improved air quality, decreased environmental impact, enhanced social responsibility, and contribute to the nation’s sustainable development objectives.


‘’According to a comprehensive research report by Market Research Future (MRFR), “Genset Market Information Report: Information by Power Rating, kVA Fuel Type Application End-Use, by Region – Global Forecast to 2030” in its recently published study report, asserts that the global market is poised to garner USD 30,590.5 Million by 2030, growing at a 5.30% CAGR during the assessment period (2022 – 2030)’’
