Indian renewable energy company ReNew Energy Global has planned to invest INR800 billion (US$8.53 billion) in the south-eastern Indian state of Andhra Pradesh across solar manufacturing and a data centre.

The company will invest INR110 billion in building polysilicon and metallurgical silicon manufacturing facilities in Anakapalli and Nellore, respectively.

Although the company did not disclose the annual nameplate capacity for the polysilicon facility, it said that the plant will be located in the same town as its ingot and wafer manufacturing factory that it is currently building. Expected to be commissioned by March 2028, the ingot and wafer facility will have an annual nameplate capacity of 6.5GW once fully operational.

Both upstream factories will complement the company’s operational solar manufacturing capacity, which includes 6.4GW of annual nameplate capacity for modules and 2.5GW for solar cells. ReNew aims to expand its solar cell annual nameplate capacity by 4GW, which is forecast to be operational in the fourth quarter of the company’s 2027 fiscal year.

On top of expanding its solar manufacturing supply chain to become fully vertically integrated, ReNew also aims to build a 1GW data centre that will be powered by renewable energy.

Sumant Sinha, founder, chairman and CEO at ReNew, said: “Andhra Pradesh is emerging as an important destination for India’s industrial and digital growth, and ReNew is proud to deepen its partnership with the state. These investments bring together two of India’s biggest growth opportunities, digitalisation and decarbonisation, while strengthening clean energy manufacturing, infrastructure and skills.”

ReNew’s increased investment in solar manufacturing in Andhra Pradesh further consolidates the state as a solar manufacturing hub. In the past few months, several Indian manufacturers unveiled plans to build solar manufacturing in the state, including 10GW+ ingot and wafer facilities from Agastya Energy and Premier Energies.
