Sterling and Wilson Renewable Energy Secures South Africa Battery Storage and Rajasthan Solar Contracts Worth Over INR 985 Crore

Sterling and Wilson Renewable Energy Limited has added two geographically distinct contracts to its order book, with a combined value exceeding INR 985 crore. The awards cover a large-scale battery energy storage deployment in South Africa and a utility-scale solar balance of system project in Rajasthan, spanning two of the company's core business lines simultaneously.

South Africa Battery Storage Assignment Comes from Returning Client

The international component of the announcement centres on two Battery Energy Storage System projects in South Africa, carrying a combined capacity of 616 megawatt-hours. The contract is structured as a turnkey engineering, procurement and construction wrap project, placing responsibility for the full delivery chain with Sterling and Wilson Renewable Energy. The South Africa order originates from a repeat customer, and the company described the assignment as a marquee project in its press release dated 22 September.

The returning client's decision to re-engage Sterling and Wilson Renewable Energy was characterised by the company as a reflection of confidence developed through previous project work together. South Africa has been among the markets where battery energy storage has attracted growing developer and utility interest, driven by persistent grid reliability challenges. A deployment of 616 MWh represents a substantial undertaking within the continent's expanding storage infrastructure landscape, and the contract places Sterling and Wilson Renewable Energy among the participants in that buildout.

Rajasthan Solar Contract Brings in a New Domestic Customer

The domestic portion of the order win involves a 534.3 megawatt-peak Balance of System project in Rajasthan, awarded by a customer new to Sterling and Wilson Renewable Energy's client base. The Balance of System scope covers the electrical and mechanical components of a solar installation that fall outside the panels themselves. According to the company's press release, the Rajasthan project is expected to reduce carbon dioxide emissions by approximately 0.80 million tonnes upon commissioning.

The award from a first-time customer signals an addition to the company's domestic client relationships at a time when India's utility-scale solar sector continues to expand, particularly across northwestern states where high irradiance levels and land availability have concentrated large-scale investment. Rajasthan has been one of the primary destinations for utility-scale solar development in India, supported by both state and central government policy frameworks that have driven substantial capital into the region.

Chief Executive Cites Execution Track Record and Customer Relationships

Chandra Kishore Thakur, Global CEO of Sterling and Wilson Renewable Energy, commented on both contract wins, describing them as reinforcing the company's business momentum and as evidence of the confidence customers place in its capabilities. He attributed the awards to consistent project execution, domain expertise, and the skilled workforce the company has built over time. Thakur specifically highlighted customer relationships as a factor underpinning both contracts, with the South Africa order in particular rooted in an established engagement with a repeat client.

Order Book Addition Spans Two Segments and Two Geographies

Sterling and Wilson Renewable Energy, listed as SWREL, operates as an engineering, procurement and construction contractor across domestic and international renewable energy markets. The latest contracts span utility-scale solar and battery storage across India and Africa, reflecting activity across distinct segments of the company's project portfolio. The Rajasthan award contributes to the broader pipeline of solar capacity being developed across India's northwestern corridor, while the South Africa contracts extend the company's presence on the African continent, where dispatchable storage capacity is being pursued alongside intermittent renewable generation. The combined order value of over ₹985 crore represents a meaningful increment to Sterling and Wilson Renewable Energy's order book, with the technological and geographic spread of the two contracts illustrating the range of project types the company is actively pursuing.
