Strengthening India’s Storage Infrastructure

The company’s latest tenders from POWERGRID further highlight its growing focus on building utility-scale BESS infrastructure, as the country’s renewable energy capacity continues to expand. BESS are expected to play an important role in balancing intermittent solar and wind generation, improving grid reliability and supporting peak power demand.

The company has already expressed its desire to become a major player in the BESS segment. POWERGRID has identified battery storage, renewable energy evacuation and High Voltage Direct Current (HVDC) transmission as the key pillars of its future growth strategy, in its recent engagements with investors. As India’s clean energy ambitions accelerate, large-scale storage projects like these are likely to be a key part of the country’s evolving power infrastructure.
