Building energy storage for faster RE integration in the grid

We are making steady progress in energy storage projects, which are crucial for addressing the intermittency challenges of renewable energy and ensuring seamless grid integration. Energy storage will be a key part of our overall future growth strategy.

Hydro-pumped storage projects (PSPs)

Our hydro-pumped storage projects (PSPs) are advancing as planned. Construction of our first 500 MW PSP on the Chitravathi River in Andhra Pradesh remains on track, and we have also secured a 1,250 MW PSP project in Uttar Pradesh. We remain committed to installing 5 GW+ PSP capacity by 2030.

Battery Energy Storage System

Recognising the recent significant cost decline and rapid scalability of Battery Energy Storage Systems (BESS), we have now incorporated large-scale BESS deployment into our strategy. This will accelerate renewable energy adoption and complement our solar, wind, and hydro PSP projects for a more resilient energy ecosystem.
