Delhi’s power demand is set to significantly rise during the summer months, particularly in late June or early July 2025, with forecasts indicating it could reach 9,000 megawatts (MW). This follows a record peak of 8,656 MW achieved in 2024, which marked the first time Delhi surpassed the 8,000 MW threshold. Notably, the peak power demand has surged over 300 percent since 2002 when it was at 2,879 MW.
To prepare for this increase in electricity consumption, local distribution companies—BSES Rajdhani Power Limited (BRPL), BSES Yamuna Power Limited (BYPL), and Tata Power Delhi Distribution (Tata Power-DDL)—have made extensive arrangements. Together, these firms cater to approximately 70 lakh consumers across the national capital territory.
In BRPL’s coverage areas, which include South and West Delhi, the peak power demand, which reached 3,809 MW last summer, is anticipated to rise to about 4,050 MW. Meanwhile, BYPL, serving East and Central Delhi, experienced a peak of 1,882 MW in 2024, with expectations of hitting around 1,900 MW this summer. For Tata Power-DDL, which operates in North Delhi, last year saw a spike to 2,481 MW, and the current forecast suggests a demand of 2,562 MW.
To meet these demands, Tata Power-DDL has secured power arrangements totaling up to 2,850 MW, which includes long-, medium-, and short-term agreements. On the other hand, BYPL and BRPL have secured over 2,100 MW of green energy sources for summer, complemented by banking arrangements for an additional 500 MW with other states. This green energy portfolio comprises approximately 888 MW from solar, 500 MW from wind, and 40 MW from waste-to-energy projects. Additionally, BSES is bolstered by over 160 MW from rooftop solar installations spread across Delhi.
In terms of contingency planning, BRPL is set to acquire up to 1,100 MW through bilateral contracts, and, in the event of unexpected issues, the discoms plan to purchase short-term power from the market as needed. Tata Power-DDL aims to ensure a consistent power supply through advanced strategies such as bilateral agreements, reserve shutdowns, and reliance on power exchanges. Their Battery Energy Storage Systems (BESS), located in Rohini and Rani Bagh, will further enhance reliability during peak demand periods.
The Power Ministry has projected that peak electricity demand in India will reach 270 GW in FY26, beginning next month, with significant consumption expected between April and June, as well as from August to October.
