In What Ways OM Steel Tubes Ltd. Achieved Operational Efficiency While Cutting Energy Cost Overhead with a 500 kW Solar Power Plant in Daruhera, Haryana
Sunpure Energy Pvt. Ltd. partnered with OM Steel Tubes Ltd. in July 2024 to help implement a 500 kW solar power plant in their Daruhera, Haryana facility comprises a combination of RCC Roof, Tin shed, and Ground-mounted solar modules, efficiently utilizing available space to maximize energy generation. The ground-mounted system features 270 Trina Solar modules, each with a capacity of 575 W, while the combined RCC roof and tin shed system includes 600 Trina Solar modules, also rated at 575 W each. As one of the leading steel manufacturers, OM Steel had a clear target—to improve sustainability and efficiency.
OM Steel Tubes Ltd sought to accomplish a vision to reduce reliance on grid power while improving their ESG score without impacting day to day activities.

Operations and Maintenance
To ensure optimal plant performance and longevity, a proactive operations and maintenance (O&M)
schedule is followed. This includes:
- 3 cleaning cycles per month across all surfaces (ground, metal, RCC), helping to maximize
irradiance absorption and maintain high output efficiency. - Routine checks of inverters and connections
- Monitoring performance via the data logging system for real-time issue detection and resolution
This structured approach has contributed significantly to the plant’s >98% uptime and stable generation.
| Key Outcomes | |
|---|---|
| Metric | Value |
| Annual Energy Offset | 720,000 kWh |
| Annual Cost Savings | ₹5.4 million |
| CO₂ Offset per Year | ~612 tonnes |
| Tree Planting Equivalent | ~27,200 trees/year |
Conclusion
The 500 kW solar power plant at OM Steel Tubes Ltd., commissioned in July 2024, generates an average of 60,000 kWh per month, totaling 720,000 kWh annually. With a hybrid setup of 270 ground-mounted modules and 600 rooftop modules, each rated at 575 W, the plant delivers a high-performance solution. The system generates savings of ₹5.4 million annually, reduces CO₂ emissions by 612 tonnes annually, and offsets the equivalent of 27,200 trees planted. This project serves as an excellent example of how industrial facilities can harness solar power to achieve both financial and environmental goals.
