Data center company Nxtra by Airtel has signed a new power wheeling agreement with independent power producer AMPIN Energy Transition for the supply of 125.65 MW of solar-wind hybrid energy through interstate transmission system (ISTS)-connected projects.

The deal will bring the total contracted green energy capacity between the two companies to over 200 MW.

According to Ashish Arora, CEO at Nxtra, the company is now powering its digital infrastructure with over 200 MW of renewable energy in partnership with AMPIN. “This achievement highlights our leadership in using ISTS-backed clean energy to power our facilities sustainably, boosting reliability and ensuring tangible climate impact.”

Under the new agreement, Nxtra will receive an additional 205,167 MWh of renewable power annually. It includes the delivery of energy in two phases through captive ISTS solar-wind hybrid projects in Rajasthan and Karnataka.

Previously, AMPIN Energy Transition had been supplying solar energy to Nxtra via intra-state open access arrangements in Uttar Pradesh, Maharashtra, and Odisha. The new arrangement will extend AMPIN’s services to 11 additional states, introducing a nationwide renewable energy solution for Nxtra using large-scale ISTS-connected infrastructure.

The expanded partnership aims to improve Nxtra’s infrastructural efficiency and strengthen its position as a leader in sustainable data center operations in India.

Nxtra utilizes renewable energy to meet 41% of its data center energy needs and is undertaking other sustainability initiatives, such as building zero-discharge data centers and deploying fuel cell technology.Last August, Nxtra by Airtel reported that 38.3% of the total electricity consumed in its core data centers was sourced from renewable energy sources during the financial year 2023-24. The use of renewable energy increased by 41% from the previous year, according to the company’s environmental, social, and governance report.

In March this year, AMPIN Energy Transition secured an investment of $50 million (~₹4.28 billion) from Siemens Financial Services, the financing arm of Siemens AG.

In November last year, AMPIN expanded its partnership with Copenhagen Infrastructure Partners to develop 2 GW of renewable energy projects across India with a joint investment of $300 million.
