Revenue model

1. EPC Project Contracts: Core revenue stream derived from turnkey Engineering, Procurement and Construction contracts across solar, data centers, MEP, industrial EPC, and transmission & distribution projects. Revenue is recognized on a project-execution basis, with marquee projects including 1,177 MWp Noor Abu Dhabi and 580 MWp Bhadla Solar Park. Turnover disclosed at ₹8,500 Cr.
2. Operations & Maintenance (O&M) Services: Recurring service revenue from Operation and Maintenance contracts for renewable energy assets, providing ongoing lifecycle support after project commissioning.
3. Generator Sales (Sterling Green): Hardware-led revenue from diesel genset sales, with Sterling Green benefiting from data center demand — ₹1,000 crore in orders last year and ₹1,350 crore in just the first two months of FY27, supported by a new manufacturing facility in Pune.
4. Data Center Turnkey EPC & Post-Completion Maintenance: Design, planning, budgeting, timeline management, Integrated System Testing and Accreditation, and 3–5 years of post-completion maintenance services for data center projects such as the Kemet Data Center in the Suez Canal Economic Zone.

Core offering

Sterling and Wilson is a global EPC (Engineering, Procurement and Construction) contractor delivering turnkey projects across utility-scale solar PV, data centers (conventional and modular prefabricated), MEP (Mechanical, Electrical, Plumbing), industrial EPC, and transmission & distribution. It also manufactures diesel generators under the Sterling Generators (Sterling Green) sub-brand, operating Asia's largest genset manufacturing plant in Silvassa and a new facility in Pune. The company's renewable energy arm (Sterling and Wilson Renewable Energy Limited) is publicly listed and reports a 21.7 GWp solar EPC portfolio.

Product overview

Sterling and Wilson operates a multi-business EPC (Engineering, Procurement and Construction) platform rather than a single unified software product. Its portfolio spans six core businesses: Turnkey Data Centers (delivered through the carved-out Sterling and Wilson Data Center / SWDC entity, with Conventional Brick & Mortar and Modular Prefabricated Data Center modules), Renewable Energy (Utility-Scale, Solar Rooftop, Floating Solar, Solar PV + Energy Storage, and Operation and Maintenance modules, operated through Sterling and Wilson Renewable Energy Limited), MEP services (Electrical, HVAC, Public Health Engineering, Firefighting, and Integrated Building Management System), Industrial EPC, Transmission & Distribution, and Sterling Generators (the diesel genset manufacturing sub-brand, also referred to as Sterling Green, with manufacturing plants in Silvassa and Pune). These businesses sit under the Shapoorji Palonji Group parent and together position the company across the solar EPC, data centre, MEP, and power infrastructure value chain in India, the Middle East, and Africa.
