Executive Summary
A Delhi NCR hospital chain faced rising diesel costs and tightening air-quality rules. Backup power was non-negotiable: ICUs, oxygen plants, and MRIs cannot blink but diesel bills of ₹6–8 lakh per month were unsustainable. Mr. Verma, Head of Utilities at Hospital, put it plainly:
“Our DGs power life-support for people so we didn’t want to touch them unless we had to. To comply with the 2023 CAQM regulations to reduce air pollution, we partnered with Energeia. But what we didn’t realise at the time is that we’d actually end up reducing our diesel cost too.”
Under the CAQM Direction – 76 – Review of regulation for use of DG sets in NCR, diesel generators in commercial buildings and factories must be converted to Dual Fuel (Partial Gas) or installed with an RECD (Retrofitted Emission Control Device) or be completely replaced by Gas Generators.

Energeia’s dual-fuel retrofit of 6 high-capacity gensets gave the hospital a new playbook: 63 kL diesel avoided, ₹15.75 lakh saved and 168 t CO₂ cut annually, with no risk to patient-critical uptime.

Key Challenges
Mr. Verma’s Concerns
When we first connected with Mr. Verma, they were already exploring solar and HVAC optimization. But their diesel dependency had remained untouched for fear of:
- Power reliability issues: “What if the switch to PNG affects critical loads?”
- Compliance concerns: Dual fuel systems had to be CPCB-compliant and fire-safe.
- Space and downtime limitations: The hospital couldn’t afford a lengthy installation.
Why Dual Fuel Kits are Critical for Hospital’s Backup DGs
India’s healthcare sector is one of the largest diesel-consuming verticals. From ventilators to MRI suites, any power cut risks becoming life-threatening. That’s why hospitals invest in oversized generator fleets. But that reliability comes at a high operational and environmental cost.
- A typical 500 kVA DG set burns over 100 litres/hour of diesel (that’s equal to fuelling 25 cars every hour, running non-stop)
- Diesel emits 2.6 kg of CO₂ per litre, worsening urban air quality in an already choking city.
- And with the Commission for Air Quality Management (CAQM) now tightening regional emission enforcement, even essential facilities like hospitals can no longer afford to ignore their diesel footprint.
But reducing diesel usage without replacing critical backup systems? That requires smart engineering.
What Makes Dual Fuel Kits Smart?

Energeia’s EnerGas Dual Fuel Kits can be retofit on existing diesel generators, converting their engines to run on a dynamic blend of natural gas + diesel.
- Plug-and-Play: Installed in under 48 hours with no DG replacement needed.
- CAQM-Compliant: Doesn’t alter DG rating and complies with the latest emission norms.
- Smart Control System: Real-time PLC + IoT logic optimizes gas-diesel ratio based on actual DG load.
- 100% Reversible: Automatic fallback to pure diesel mode if PNG supply is interrupted.

The Solution
Energeia deployed its EnerGas Dual Fuel Retrofit Kits on the hospital’s high-capacity gensets:
- 4 units of 500 kVA DFKs
- 2 units of 750 kVA DFKs
All installations were completed without disrupting hospital operations, scheduled around low-demand hours and routine maintenance slots.
| Impact Achieved | Metrics |
|---|---|
| Diesel Saved | 63 KL |
| Annual Fuel Cost Savings | ₹15.75 Lakh |
| CO₂ Emissions Avoided | 168.2 Tonnes |

From One Success to Many
The first deployment was just the beginning. After experiencing tangible cost savings and smooth operations at the Delhi facility, the hospital chain expanded Dual Fuel adoption across their Faridabad and Noida sites as well. What began as a cautious pilot became a replicable strategy — driven by measurable savings, engineering reliability, and regulatory confidence.
The Next Step
Ready to become compliant and cut your diesel costs?
Energeia has successfully implemented dual fuel kits across hospitals, pharma plants, and data centers—helping them unlock real energy savings while staying fully compliant.
Frequently Asked Questions
Q1. Will my generators still work with 100% diesel if PNG is unavailable?
Absolutely. Energeia’s dual fuel system ensures full fallback to diesel at any time, without any derating.
Q2: Is this fully-compliant with CAQM or PCB norms?
Yes. As per CAQM Direction, DG sets up to 800 kW in Delhi-NCR must either switch to dual-fuel mode or install emission devices that reduce PM by at least 70%, even outside the GRAP season. Energeia’s Dual Fuel Kits are fully compliant and certified. 👉 Read the official PIB notice.
Q3: How long does the retrofit process take?
Installation typically 1–2 days per DG, with zero disruption to hospital operations. We often schedule installs during non-peak hours or maintenance windows.
Q4: Can this work if I don’t have a PNG line?
Yes. While PNG enables the best ROI, we also offer custom fuel-mix solutions that can work with LNG and LPG infrastructure where applicable.
