Telecommunications service provider Bharti Airtel’s data center subsidiary Nxtra will procure 140 GWh of renewable energy every year for its data centers in Tamil Nadu, Uttar Pradesh, and Odisha.

The company has partnered with AmpIn Energy and Amplus Energy to set up captive solar and wind power projects totaling 72.3 MW_dc capacity to power its data centers under 25-year agreements and reduce carbon footprint by around 99,547 tonnes of carbon dioxide equivalent (CO2e) per year.

“The additional clean energy supply will increase our renewable energy share to approximately 70% in the overall energy mix for our core data centers. As we work towards building more capacity in coming years and gear up for Generative AI-powered loads, we are fully cognizant of our responsibility towards the environment and are prepared to mitigate the impact on climate,” said CEO Ashish Arora in a statement.

Nxtra’s data center in Tamil Nadu will be powered by 24.3 MW wind and 28 MW_dc solar projects built in partnership with Amplus Energy. The company said it will result in about 77,957 tonnes of CO2e emissions reduction every year.

In Uttar Pradesh, a 12 MW_dc solar project will be built in partnership with AmpIn Energy, resulting in an annual reduction of about 12,694 tonnes of CO2e emissions. As for Odisha, Ampln Energy will build an 8 MW_dc solar project, which will reduce emissions of about 8,896 CO2e annually.

Nxtra has 12 large and 120 edge data centers across India.

Last year, the company said it would purchase 23,000 MWh of renewable energy by the fourth quarter of the financial year 2023-24 through the open access route, where Airtel will invest in Continuum Green’s project company, ensuring a sustainable supply of green power from solar and wind energy projects to Nxtra’s Edge data centers in Madhya Pradesh.

In 2022, Nxtra said it has partnered with solid-oxide fuel cell manufacturer Bloom Energy to deploy a low-environmental impact fuel cell installation at its data center in Karnataka. The company claimed it would be the first Indian data center to deploy fuel cell technology to mitigate carbon emissions through a cleaner, hydrogen-ready fuel supply.
