Sterling Yercaud Achieves ₹16.8L Annual Savings with LPGenius + FuelFusion

Executive Summary

Sterling Holiday Resorts – Sterling Yercaud operates in a hill station region with approximately 9 hours of daily grid downtime, leading to heavy reliance on diesel generators and rising fuel costs. The property also depended on 19 kg VOT LPG cylinders for kitchen operations, resulting in high handling intensity and indirect inefficiencies.

Pune Gas engineered a structured hybrid energy transformation through the deployment of dual LPGenius systems—one for kitchen operations and another for DG operations—integrated with FuelFusion Dual Fuel Technology. This enabled a transition from a diesel-dominant setup to a hybrid LPG–diesel architecture.

The intervention delivered up to 45% diesel reduction, ₹16.8 lakhs in annual savings, and a payback period of ~7 months, significantly improving operational efficiency and cost control.

Before (Diesel-Dominant Operations + 19 kg VOT LPG)

Monthly
  • ~9 hours daily grid outage with 100% diesel-based DG usage
  • High diesel consumption with price volatility exposure
  • Frequent handling of 19 kg VOT cylinders
  • Indirect manpower dependency and handling losses
  • No structured LPG infrastructure for hybrid scaling

After (Hybrid LPG–Diesel System with LPGenius & FuelFusion)

Monthly
  • Up to 45% diesel displacement
  • Structured LPG system with 47.5 kg LOT cylinders
  • Reduced cylinder handling and improved vaporisation
  • Stable hybrid energy architecture for DG + kitchen operations
  • Annual savings: ₹16.8 Lakhs
  • Payback period: ~7 months

Client Overview

Sterling Holiday Resorts is a leading hospitality brand operating premium resorts across India. The Yercaud property operates in a terrain-sensitive region where uninterrupted power and efficient fuel systems are critical for guest experience and operational continuity.

The Challenge

The resort faced sustained operational pressure due to:

  • ~9 hours of daily power outages 
  • Complete dependence on diesel generators during outages 
  • High diesel consumption and exposure to fuel price volatility 
  • Frequent handling of 19 kg VOT LPG cylinders 
  • Indirect manpower deployment and handling inefficiencies 
  • Lack of a structured LPG infrastructure for hybrid operations 

The existing system was both financially inefficient and operationally exposed.

The Solution

Pune Gas implemented an integrated hybrid architecture combining LPG infrastructure optimisation with intelligent fuel blending.

LPGenius – Kitchen Operations

  • Transition to 47.5 kg LOT cylinders 
  • Structured LPG distribution system 
  • Improved vaporisation stability 
  • Reduced cylinder handling intensity 

LPGenius + FuelFusion – DG Operations

  • Dedicated LPG supply to DG systems 
  • Intelligent LPG–diesel blending for DG sets 
  • Diesel displacement during peak outage periods 

This created a stable, scalable hybrid energy backbone supporting both hospitality operations and power generation.

  • Projected Annual Savings: ₹16,80,744 
  • Diesel Displacement: Up to 45% 
  • Total Investment: ~₹11,00,000 
  • Projected ROI: ~7 months

Strategic Outcomes

The hybrid deployment delivered:

  • Reduced diesel dependency and fuel price exposure 
  • Stabilised power supply during high occupancy periods 
  • Lower indirect manpower and handling losses 
  • Structured LPG backbone for long-term scalability 
  • Direct improvement in operating margins

Execution

The project was executed with precise engineering and seamless integration of LPGenius systems and FuelFusion technology, ensuring uninterrupted resort operations during deployment.

Conclusion

Through dual LPGenius deployment and FuelFusion integration, Sterling Holiday Resorts – Sterling Yercaud successfully transitioned to a financially optimised and operationally resilient hybrid energy infrastructure. The project sets a benchmark for energy optimisation in hospitality environments operating under challenging terrain and power conditions.
