⚡ Quick Read
- What happened: General Mills India commissioned a 600 kW rooftop solar plant at its Malegaon facility, resulting in annual savings of over ₹7.5 million.
- Why it matters: The project demonstrates the high ROI potential for C&I consumers, with a payback period of less than three years and a 20% reduction in power costs.
- Watch: General Mills is currently evaluating a captive renewable energy project and potential battery storage integration by 2029.
Background and Context
As industrial power consumers in India face rising operational costs, the shift toward captive rooftop solar solutions has accelerated. General Mills India, the multinational food giant behind brands such as Pillsbury and Häagen-Dazs, has strategically utilized its unused rooftop real estate at its Malegaon facility in Maharashtra to mitigate high electricity expenditures. Prior to this installation, the facility faced a monthly electricity bill exceeding ₹3 million, totaling approximately ₹36 million annually.
Key Details
Commissioned in June 2025 by Maharashtra-based Polaris Renewable Solutions, the 600 kW rooftop project was executed at a total cost of ₹21 million. The system utilizes Axitec 550 Wp Mono PERC modules paired with Solaris 110 kW inverters. Operating under a net metering framework, the installation generates 2,400 units of electricity daily, or 67,000 units monthly, effectively offsetting 20% of the facility’s total power requirements. The project is projected to achieve a full return on investment in less than three years.
What This Means for EPCs and Developers
For EPC contractors, this project highlights the technical complexities inherent in C&I rooftop installations. Polaris Renewable Solutions noted that navigating multiple roof dimensions and varying tilt angles presented significant engineering challenges. However, the success of this project underscores the viability of the C&I sector, where solar installations can offer 20% to 30% savings with minimal transmission losses. Developers should note that while rooftop solar provides immediate cost relief, larger industrial consumers are increasingly looking for hybrid solutions, including open access and battery storage, to scale their renewable energy consumption beyond the 50% mark.
What Happens Next
General Mills India is signaling a broader commitment to sustainability and energy independence. The company is currently in advanced discussions regarding the procurement of additional renewable energy through a captive project. Furthermore, there is a strategic roadmap to integrate the existing rooftop solar system with battery energy storage technology by 2029. This integration would allow the facility to store surplus solar generation for use during non-solar hours, further stabilizing energy costs and reducing reliance on the grid.
