India power consumption hits 164.98 BU in May, up 11.55% on heatwave surge
Synopsis
India's power grid hit an all-time peak of 270.82 GW on 21 May 2026 — crossing the 270 GW threshold for the first time ever — as a relentless heatwave pushed electricity consumption to 164.98 BU for the month, an 11.55% jump year-on-year. With the IMD forecasting more heat ahead, the record may not stand for long.
Key Takeaways
India's power consumption rose 11.55% YoY to 164.98 BU in May 2026 , up from 147.89 BU in May 2025.
Peak demand hit an all-time record of 270.82 GW on 21 May 2026 , surpassing the previous high of ~ 250 GW from May 2024.
Fresh demand records were set on four consecutive days — 18 to 21 May .
The Power Ministry had projected a 270 GW peak for summer 2026; the grid met that mark exactly.
The IMD has forecast a harsh summer ahead, with demand expected to stay elevated in coming weeks.
India's power consumption surged 11.55 per cent year-on-year to 164.98 billion units (BU) in May 2026, driven by intense heatwave conditions that pushed households and businesses to ramp up cooling appliances across the country, according to official data. The figure compares with 147.89 BU recorded in May 2025.
Record Peak Demand
Peak power demand scaled an all-time high of 270.82 gigawatts (GW) during the month, up sharply from 230.99 GW in the corresponding period last year. The new record surpasses the previous all-time high of approximately 250 GW set in May 2024.
Notably, peak demand set fresh records on four consecutive days in May — reaching 257.37 GW on 18 May, climbing to 260.45 GW on 19 May, rising further to 265.44 GW on 20 May, and hitting the record 270.82 GW on 21 May. Prior to this run, the year's highest demand had been 256.11 GW on 25 April.
Government Projections Met
The Power Ministry had projected peak electricity demand would touch 270 GW during the summer of 2026 — a target the grid effectively met on 21 May. For context, the highest demand recorded last summer was 242.77 GW in June 2025, which had itself fallen short of the government's estimated peak requirement of 277 GW for that season.
IMD Forecasts Prolonged Heat
The India Meteorological Department (IMD) has projected a harsh summer this year, signalling that electricity usage is likely to stay elevated as consumers continue relying heavily on air conditioners, desert coolers, and other cooling equipment. Industry experts expect both power demand and consumption to remain high in the coming weeks, supported by above-normal temperature forecasts.
Pressure on the Grid
The sustained surge reflects mounting pressure on India's power infrastructure as extreme weather events grow more frequent and intense. This is the first time peak demand has crossed the 270 GW threshold in the country's history, underscoring the scale of the challenge for grid operators and power distribution companies heading into the peak summer months.
Point of View
But it is also a warning. India's power infrastructure was built for a different climate baseline, and back-to-back record days expose the fragility of distribution networks — not just generation capacity. The Power Ministry deserves credit for an accurate forecast, but the harder question is whether transmission and last-mile infrastructure can absorb the next surge without widespread outages. With the IMD signalling no near-term relief from the heat, grid operators are effectively stress-testing the system in real time.

Frequently Asked Questions
What was India's power consumption in May 2026?
India's power consumption in May 2026 was 164.98 billion units (BU), a rise of 11.55 per cent compared to 147.89 BU recorded in May 2025. The increase was driven primarily by intense heatwave conditions boosting demand for cooling appliances.
What is the all-time peak power demand record in India?
India's all-time peak power demand record is 270.82 GW, set on 21 May 2026. This surpassed the previous all-time high of approximately 250 GW recorded in May 2024.
Why did power demand surge in May 2026?
Intense heatwave conditions across India drove households and businesses to increase use of air conditioners, desert coolers, and other cooling equipment, placing exceptional strain on the power grid throughout May 2026.
Did India meet the Power Ministry's peak demand projection for 2026?
Yes. The Power Ministry had projected peak electricity demand would reach 270 GW during summer 2026, and the grid touched exactly 270.82 GW on 21 May 2026, effectively meeting that forecast.
Will power demand remain high in the coming weeks?
Industry experts expect demand and consumption to stay elevated, backed by the India Meteorological Department's forecast of above-normal temperatures continuing through the summer season.
