- Sterling and Wilson Renewable Energy Limited (SWSOLAR.NS) provides end-to-end engineering, procurement, and construction (EPC) solutions for solar power projects, along with operations and maintenance (O&M) services; utility-scale solar installations; rooftop solar solutions; floating solar projects; hybrid energy systems; and battery energy storage projects. The company operates through two primary segments, EPC and O&M, delivering design, engineering, procurement, construction, commissioning, and asset management services to third-party projects. It targets utility developers, independent power producers, and commercial customers across 28 countries, including India, the Middle East, Africa, Europe, the Americas, South East Asia, Australia, and Latin America.
Headquartered in Mumbai, India, and founded in 2017 through the demerger of the solar EPC division of Sterling and Wilson Private Limited—which traces origins to 2011 operations—the company ranks among the world's largest solar EPC providers with over 10 GW of executed projects and a pipeline exceeding 12 GW. Backed by shareholders including Reliance New Energy Limited (holding approximately 32.5%) and Shapoorji Pallonji entities, it maintains strong ties to the Shapoorji Pallonji Group heritage while pursuing independent growth in renewables.
Recent developments include a five-year strategic partnership framework agreement with Adani Green Energy, valued at Rs 1,381 crore, encompassing a Balance of System package for 1 GW across three solar projects at the Khavda Renewable Energy Park in Gujarat; this marks the company's largest domestic EPC order for fiscal 2026, pushing total order inflows beyond Rs 6,450 crore and adding to nearly 6 GW under execution in the region. In November 2025, Sterling and Wilson secures a turnkey 240 MW AC solar PV contract in South Africa worth approximately USD 147 million (Rs 1,313 crore); it also attains record unexecuted order value surpassing Rs 10,500 crore. Additional wins feature a Rs 1,130 crore order from NTPC Renewable Energy Limited and a 1,000 MWhr battery storage project in Rajasthan, alongside Rs 1,500 crore raised via qualified institutional placement to bolster expansion.
