What Are Ban-Free DG Sets & Generators?
Ban-free DG sets & generators are generators that stay permitted when older diesel sets are restricted. The rules are set by the Commission for Air Quality Management (CAQM) in the National Capital Region and by state pollution control boards elsewhere.
Three kinds of equipment are usually meant by the term:
- New diesel gensets up to 800 kW built to the CPCB IV+ standard notified under GSR 804(E).
- Gas generators running on LPG, natural gas, biogas, propane or butane.
- Older diesel sets converted to dual-fuel mode or fitted with certified RECD systems, where the rules allow it.
Buyers searching for a ban free dg set want to avoid a stopped site, a sealed set or a penalty. The right question is not “is it ban-free?” but “which rule applies to this unit, at this site, at this capacity?”
Ban-Free DG Sets & Generators: What the Regulations Say
Diesel generator use in the NCR is regulated even outside GRAP periods. Under GRAP Stage II to IV, DG sets face a general ban, with listed exceptions. That is why ban-free equipment matters most between October and February.
Ban-Free DG Sets & Generators Under CAQM Direction No. 76
CAQM issued Direction No. 76 on 29 September 2023. It was amended on 22 February 2024. The table below summarises how it treats the main categories.
| Generator category |
Emission requirement |
Status during GRAP restrictions |
| New diesel gensets up to 800 kW, made to GSR 804(E) (CPCB IV+) |
Compliance with the notified standard |
No restrictions, even during GRAP periods |
| Gas gensets of all capacities (LPG, natural gas, biogas, propane, butane) |
None specified |
No restrictions, even during GRAP periods |
| Sets of 800 kW and above |
Any emission control mechanism that meets the prescribed stack standards |
No restrictions, subject to compliance |
| Older in-use diesel sets below 800 kW |
Dual-fuel mode or certified RECD, depending on capacity band |
Depends on the band. Check the current amended direction. |
Capacity bands for older sets were revised in the 2024 amendment, and secondary sources differ on the exact cut-offs. Always check the current CAQM text for your unit.
Compliance matters. CAQM’s standard schedule of environmental compensation, dated 1 January 2025, sets daily charges for each violation: Rs. 7,500 for 20–125 kW, Rs. 15,000 for above 125 kW but below 800 kW, and Rs. 25,000 for 800 kW and above. Renting a compliant set costs less than a sealed one.
Ban-Free DG Sets & Generators Outside the NCR
Rules outside the NCR vary by state. CPCB recommended in March 2024 that state boards consider implementing CAQM Direction No. 76. Gujarat’s pollution control board is reported to have issued a circular on 7 July 2026 extending these requirements to its non-attainment cities. Check your state board’s current position before finalising a site plan.

Do not treat kW and kVA as the same. Generators are sold in kVA, but CAQM bands are set in kW. At a typical 0.8 power factor, 1,000 kVA is about 800 kW.
Industries Using Ban-Free DG Sets & Generators
- Manufacturing and industrial units. Plants cannot stop a shift because a set is restricted. Ban-free DG sets & generators give units in regulated areas a compliant backup. Larger factories usually need the 500 kVA to 2,000 kVA range.
- Construction sites. Cranes, batching plants and site lighting need steady power. Rented sets avoid the cost of owning equipment for a fixed project period.
- Commercial buildings and offices. Towers, malls and offices use backup power for lifts, pumps and lighting. A compliant set reduces enforcement risk during winter pollution orders.
- Healthcare facilities. Hospitals need uninterrupted power. Emergency-service exceptions exist, but they are narrow and change by order. A compliant set removes dependence on them.
- IT and data centres. Uptime targets leave no room for a generator that may be switched off. Capacity, redundancy and compliance must be planned together.
- Events and temporary installations. Exhibitions and large gatherings need short-term power. Rental suits this need.
How to Choose Ban-Free DG Sets & Generators?
- Calculate the load. Add up running load and motor starting load. Select capacity with headroom, but avoid heavy oversizing.
- Convert units properly. Check the CAQM band in kW, not kVA.
- Confirm the applicable rule. Rules differ between the NCR and other states.
- Choose the fuel route. Gas gensets face fewer restrictions but need gas supply at the site.
- Ask for documents. Request emission compliance papers for each unit before delivery.
- Plan the duration. Short events and multi-year projects need different rental terms.
- Check site access. Confirm the plinth, cabling, exhaust, ventilation and transport route.
