CPCB IV+ Generator Sets for India

CPCB IV+ refers to the revised emission requirements applicable to specified internal combustion engines used for power-generating sets in India. The revised emission standards were notified through the Environmental Protection (Third Amendment) Rules, 2022.

For businesses installing a new DG set, selecting a generator designed for the applicable regulatory requirements is an important part of project planning.

Why CPCB IV+ Matters

The updated emission framework addresses pollutants associated with generator-set operation and includes requirements relating to emission performance and testing.

Depending on the generator category and application, the relevant technical configuration may include engine and exhaust after-treatment technologies.

CPCB IV+ DG Set Applications

CPCB IV+ compliant generator solutions are relevant for applications such as:

  • Commercial buildings
  • Hospitals
  • Industrial plants
  • Data centres
  • Infrastructure
  • Manufacturing facilities
  • Hotels
  • Institutional buildings

The exact applicable requirements should always be verified against the current regulatory requirements and the specific generator configuration.

Choosing a CPCB IV+ Generator

When evaluating a DG set, consider:

  • Required kVA rating
  • Applicable emission category
  • Engine specification
  • After-treatment system where applicable
  • Installation environment
  • Control system
  • Acoustic requirements
  • Service support

Supernova offers CPCB-compliant generator solutions across its product range. See also: CPCB IV+ DG set selection factors.
