History
Sterling & Wilson began in 1927 as an electrical contracting firm through a partnership between Wilson Electric Works and the Shapoorji Pallonji Group.[3] Over time, the company diversified into MEP contracting, diesel-based power, solar EPC, and turnkey infrastructure.[4]
In 2019, the renewable energy business was demerged and listed independently. Each business operates independently, with its own leadership and operational structure.[5]
