Sterling and Wilson Renewable Energy has secured two major contracts valued at ₹985 crore. The agreements include a 534.3 MWp solar project in Rajasthan and utility-scale battery storage facilities in South Africa.
Why it matters
These contracts underscore the growing global demand for integrated renewable infrastructure, spanning both large-scale solar generation and energy storage capacity. The expansion reflects a strategic shift toward turnkey storage solutions in international markets.
The awards comprise a 534.3 MWp Balance of System solar project in Rajasthan and a 616 MWh battery energy storage system (BESS) deployment in South Africa. The South African contract represents the company’s second-largest utility-scale battery project to date.
The players
Sterling and Wilson Renewable Energy
A global engineering and construction firm specializing in solar power plant development, balance of system packages, and utility-scale energy storage.
The details
In Rajasthan, the company is tasked with executing a Balance of System package, which encompasses all components of a photovoltaic plant excluding the modules. The South African engagement is a turnkey EPC (engineering, procurement, and construction) wrap project, meaning the firm assumes full responsibility for the design, material sourcing, and physical build of the battery arrays. These storage systems are critical for stabilizing energy distribution by compensating for the intermittent nature of solar power generation.
Timeline

The Tech Race
This move highlights the competitive race to scale utility-scale battery energy storage systems as a primary tool for grid modernization. The deployment reflects an industry-wide effort to move beyond simple generation and toward full-stack energy management.
These projects will eventually increase local grid stability in Rajasthan and South Africa by integrating reliable storage with renewable generation. While construction timelines remain unannounced, the scale of these facilities suggests significant capacity increases for the local power systems.
The takeaway
The firm’s pivot toward large-scale storage marks a significant trajectory shift for its international portfolio. Investors should monitor the progress of the South African site, as its 616 MWh capacity provides a critical benchmark for the company’s ability to execute complex, multi-national energy projects.
