Expanding Clean Energy Supply
The additional capacity will be supplied to Nxtra in two phases through captive solar-wind projects located in Rajasthan and Karnataka. Previously, AMPIN had been supplying renewable power to Nxtra through intra-state open access in Uttar Pradesh, Maharashtra, and Odisha. The latest agreement adds 11 new states and introduces large-scale ISTS solutions, enabling seamless power delivery across the country from a single Independent Power Producer (IPP).
Ashish Arora, CEO – Nxtra by Airtel, said the company remains committed to building sustainable digital infrastructure. "By powering our digital infrastructure with over 200 MW of renewable energy through our partnership with AMPIN, we are setting new standards for the industry. This achievement highlights our leadership in using ISTS-backed clean energy to power our facilities sustainably, boosting reliability and ensuring tangible climate impact," he said.
