Each winter, Delhi NCR enters alarming air quality levels. The government activates the Graded Response Action Plan (GRAP) to control pollution. One of the biggest impacts?
- Restrictions on running diesel generators.
For factories, malls, corporate offices, construction sites, and hospitals, this creates an immediate challenge:
How do you keep operations running legally during GRAP?
The answer is CPCB IV+ compliant gensets.
They meet advanced emission standards and remain permitted where older DG sets are banned. This blog explains how they work, rental prices, and how to choose the right size for your business.
What is GRAP & Why DG Sets Are Affected?
GRAP is implemented by CAQM (Commission for Air Quality Management) to reduce seasonal pollution in NCR.
As pollution crosses certain thresholds (Stage I–IV), different actions are implemented:
- Diesel generator bans (CPCB II or older)
- Restrictions on construction, transport & waste movement
- Halt on polluting industries
Because generators burn diesel, older models create heavy PM, HC & NOx emissions, directly contributing to smog.
So when GRAP kicks in, non-compliant DG sets are stopped immediately — with heavy penalties for misuse.
What is CPCB IV+? (And Why It’s Legal During GRAP)
CPCB 4+ (CPCB IV Plus) is India’s latest emission standard replacing CPCB II.
Major improvements:
- 90% less particulate emissions
- Lower nitrogen oxides
- Advanced exhaust after-treatment
- Real-time monitoring capability
- Digital compliance & logging
CPCB IV+ gensets are legally allowed in Delhi NCR during GRAP, provided documentation is available and equipment is certified.
Why Renting CPCB IV+ Gensets is Better Than Buying?
Switching your existing plant to CPCB IV+ permanently is expensive.
Renting solves the problem immediately:
Zero capital Commitment
Buying a CPCB IV+ genset would have consumed your capital whereas rental converts it to OPEX.
No maintenance burden
All types of services & breakdown will be handled by rental partner.
Compliance is our responsibility
You receive:
- CPCB IV+ compliance certificate
- Emission label
Swap models as your load changes
Fit-out, commissioning, peak season — your load isn’t static.
Rental lets you adjust.
Our CPCB IV+ Fleet (Delhi NCR)
Sudhir Rentals provides CPCB IV+ range from 58.5 kVA to 2250 kVA, including containerized systems for large industrial/commercial use.
Available Capacities
- 58.5 kVA – 125 kVA
For retail, clinics, warehouses, showrooms, lifts, site offices - 160 – 500 kVA
Fit-outs, medium factories, hotels, sports complexes, malls - 750 – 1500 kVA
Manufacturing clusters, high-rise construction, metro projects - 1800 – 2250 kVA (Containerised)
Data centers, hospitals, airports, 24/7 load requirements
How to Choose the Right CPCB IV+ Genset?
1. Determine your actual running load (not connected load)
Example:
- AC 10 HP motor
- Welding machine 8 kVA
- Lights, computers etc.
Running load ≠ maximum load.
Use a rule: choose genset 20–30% higher than peak running requirement.
2. Consider starting current
Motors, chillers, elevators, compressors → surge 2–5× higher.
This is why a site that “runs at 80 kVA” may need a 125 kVA generator.
3. Runtime & fuel logistics
If using 10–12 hours/day → consider efficiency, fuel tank size & refill schedule.
4. Site placement
- Basement: noise + exhaust ducting
- Rooftop: crane lifting
- Ground: accessibility + security
5. Operator & monitoring
A trained operator avoids overloads, wet stacking, SCR clogging, and battery faults.
Where CPCB IV+ Gensets Are Most Used in NCR?
- Hospitals & Healthcare
