Delhi's Electricity Landscape Transforms with Massive Consumer Growth and Efficiency Gains
According to the Delhi Economic Survey 2025-26, tabled in the Delhi Assembly on Monday, the national capital has witnessed a remarkable expansion in its electricity consumer base. The number of consumers has surged from 52.6 lakh in the fiscal year 2015-16 to an impressive 73.6 lakh in 2024-25, marking a substantial increase of nearly 21 lakh new connections. This growth highlights the city's evolving energy demands and infrastructural developments.
Domestic Users Dominate as Technical Losses Sharply Decline
Of the total consumer base, domestic users account for a dominant 84.1%, underscoring the residential sector's pivotal role in Delhi's power consumption patterns. Concurrently, aggregate technical and commercial (AT&C) losses, which measure the gap between energy supplied and revenue realized, have experienced a dramatic reduction. From a peak of 52% during the pre-reform period in 2002, these losses have plummeted to just 5.9% in 2024-25. The survey credits this significant improvement to enhanced billing systems, more efficient collection methods, and overall distribution efficiency upgrades, positioning AT&C losses as a key performance indicator for power utilities.
Rising Power Demand and Consumption Trends
Peak power demand in Delhi has also escalated substantially, climbing from 5,846 megawatts (MW) in 2015-16 to 8,442 MW in 2025-26. This rise reflects the city's growing energy needs amid urbanization and economic activities. Furthermore, electricity consumption has grown at an average annual rate of approximately 3.2% between 2015-16 and 2024-25, indicating steady and sustained usage patterns across sectors.
Solar Energy Adoption Accelerates with Policy Support
The Delhi government is actively promoting rooftop solar installations through the Delhi Solar Energy Policy, 2023, which offers enhanced incentives to boost adoption. Under this policy, the capital subsidy has been increased to Rs 10,000 per kilowatt (kW), with a cap of Rs 30,000 per consumer, making solar energy more accessible and affordable for residents and businesses alike.
As per the report, solar adoption has gained significant momentum, with installations now covering 21,915 consumers and achieving a cumulative capacity of 425 MW as of January 2026. Notably, more than 12,500 of these installations, contributing about 166.7 MW, were completed after the policy came into effect in March 2024. To further accelerate uptake, the government has mandated solar panels for all government buildings with rooftop areas of 500 square meters or more, as well as for private buildings on plots of 105 square meters and above, in alignment with updated building bylaws.
This comprehensive approach not only supports renewable energy goals but also enhances Delhi's energy security and sustainability for the future.
