NEW DELHI: The number of electricity consumers in Delhi has risen from 52.6 lakh in 2015-16 to 73.6 lakh in 2024-25, an increase of nearly 21 lakh, with domestic users accounting for 84.1% of the total, according to the Delhi Economic Survey 2025-26 tabled in the Delhi Assembly on Monday.As per the official data, the consumer base has expanded by 20.9 lakh during the period.At the same time, aggregate technical and commercial (AT&C) losses — the gap between energy supplied and revenue realised — have plunged from a high of 52% in the pre-reform period of 2002 to just 5.9% in 2024-25. The survey attributes the decline to improvements in billing, collection and distribution efficiency. AT&C losses are considered a key indicator of the overall performance of power distribution utilities.Peak power demand has also climbed, from 5,846 MW in 2015-16 to 8,442 MW in 2025-26, while electricity consumption grew at an average annual rate of about 3.2% between 2015-16 and 2024-25.Delhi govt is promoting rooftop solar installations through enhanced incentives under the Delhi Solar Energy Policy, 2023. The capital subsidy has been raised to Rs 10,000 per kW, capped at Rs 30,000 per consumer.According to the report, solar adoption has gained momentum, with installations covering 21,915 consumers and a cumulative capacity of 425 MW as of Jan 2026. Of this, more than 12,500 installations, adding about 166.7 MW, were completed after the policy came into force in March 2024. To accelerate uptake, solar panels have been made mandatory for govt buildings with rooftop areas of 500 sq m or more, and for private buildings on plots of 105 sq m and above, in line with building bylaws.
