The quarter's performance was driven by broad-based growth across Generation, Renewables, Transmission & Distribution and emerging consumer-focused green businesses. The quality and resilience of the earnings continue to strengthen, with regulated and long-term contracted businesses accounting for an increasing share of EBITDA, providing greater predictability and visibility of cash flows and profitability. During H1 FY27, the Company invested ~₹10,000 crore, its highest half-yearly capital deployment, reinforcing its commitment to building critical infrastructure to meet India's growing energy needs and support its transition towards a secure, reliable and sustainable energy future. India's electricity demand continued to witness sustained growth in H1 FY27, driven by industrial and economic activity, agricultural consumption, rising household demand, increasing EV adoption and the expanding data centre ecosystem.

Renewable businesses remained a key driver of earnings growth, underpinned by 1.4 GW of capacity additions over the last twelve months, strong manufacturing margins and yields, and continued leadership in rooftop EPC with over 5.1 GWp of cumulative installations. Odisha distribution continued its strong operational performance, with AT&C losses improving by 5.7% over Q1 FY27. Following Cyclone Arnab, electricity supply was restored within 48-72 hours in affected area, highlighting the resilience of the tech powered network and operational capabilities of field teams.
