AirTrunk has filed detailed plans for two hyperscale data centre campuses in southern India that could involve about Rs 1.03 lakh crore of investment, advancing one of the country’s biggest proposed digital-infrastructure projects.

The Blackstone-backed operator has submitted a detailed project report for two campuses with combined capacity of 1.8 gw in the Andhra Pradesh, according to an emailed statement from the company.

The proposal remains under consideration by State authorities.

The project will deepen Andhra Pradesh’s push to become a major data centre hub as concerns grow over the power and water needed to support large projects in the State.

Andhra Pradesh Chief Minister N Chandrababu Naidu has said that the government is expanding renewable energy capacity and strengthening water supplies to support the buildout.

Alphabet’s Google is separately developing a $15-billion AI hub in Andhra Pradesh.

AirTrunk has said that its proposed campuses will use low-water, air-cooled technology and industrial water supplies rather than municipal sources.
