Singapore-based Sembcorp Industries Ltd. is preparing to file for an initial public offering of its Indian unit, Sembcorp Green Infra Ltd., that could raise as much as $500 million, according to people familiar with the matter.

The filing would position the company to tap into India's growing renewable infrastructure market, providing capital for future expansion projects.

Analysts expect the IPO to attract interest from both domestic and international investors seeking exposure to the Asian green energy sector.

The move underscores Sembcorp's confidence in the long‑term growth of India's sustainable energy sector.
