Understanding CPCB IV+ Norms: What They Mean for Diesel Generator Users in India
What is CPCB IV+?
CPCB IV+ is the latest emission compliance standard issued by the Central Pollution Control Board of India. It governs how much pollution a diesel generator (up to 800kW) is allowed to emit.
This new standard came into mandatory effect on July 1, 2023, replacing the earlier CPCB II norms. It marks a significant shift toward cleaner and more environmentally responsible power generation.
Why Was CPCB IV+ Introduced?
- Reduce air pollutants such as particulate matter (PM), nitrogen oxides (NOx), and hydrocarbons.
- Promote cleaner engine technologies across the power generation sector.
- Align India’s emission norms with global standards like the EU Stage V.
- Support national sustainability and clean air goals.
What’s New in CPCB IV+ Compared to CPCB II?
| Feature | CPCB II | CPCB IV+ |
| Emission Limits | Moderate | Much stricter |
| Engine Tech | Basic | Advanced (CRDI, DPF, SCR) |
| Compliance Cost | Lower | Higher, but eco-friendly |
| Fuel Compatibility | Regular diesel | Higher efficiency expected |
What This Means for You
- All new diesel generators sold after July 1, 2023, must comply with CPCB IV+ norms.
- If you're currently using an older CPCB II model, you can continue to use it, but upgrades will be necessary for future compliance.
- Radiant Power Projects offers CPCB IV+ compliant DG sets to ensure you meet government regulations while maintaining top-level performance and reliability.
