Adani Green Energy Ltd plans to more than double its battery energy storage system (BESS) capacity at the Khavda renewable energy park in Gujarat to over 7 GWh by FY27, supported by a capital expenditure programme of around Rs 250–400 billion.

The company is set to commission 3.5 GWh of storage capacity by the end of the current financial year, which it has described as India’s largest battery storage project. Battery storage has emerged as a strategic priority for Adani Green as delays in grid augmentation continue to constrain power evacuation from Khavda, located near the India–Pakistan border in Kutch district.

Adani Green said battery storage would help absorb power that might otherwise be curtailed in the short term while providing flexibility until long-term evacuation infrastructure is aligned with project commissioning. The company expects to significantly improve revenue realisation by co-locating solar generation with storage, enabling it to dispatch stored energy during peak pricing periods and benefit from arbitrage opportunities.

Grid constraints remain a key near-term challenge at Khavda, where evacuation capacity expansion has lagged expectations due to execution delays, seasonality and right-of-way issues. Adani Green noted that battery storage would play a critical role in mitigating these risks and stabilising generation variability as renewable capacity scales up.

The accelerated rollout of BESS forms a central part of the company’s capital expenditure roadmap for the coming year. Adani Green said funding visibility remains strong, with a significant portion of debt already sanctioned to support the next phase of expansion.

With most near-term growth concentrated in Rajasthan and Khavda, Adani Green expects battery storage to be a crucial enabler of renewable energy integration and grid stability, strengthening its position in India’s energy transition.
