New Delhi: India's electricity grid broke its own demand record yet again on Wednesday, with peak power demand touching 265.44 GW during solar hours, the fourth all-time high in 26 days, and the third successive day on which the country has set a new peak.

The Union Ministry of Power confirmed the latest milestone on X. "Today (May 20), at 1545 hours, peak power demand (solar hours) of 265.44 GW was successfully met. This represents a new high in peak demand met, surpassing yesterday's peak demand (solar hours) of 260.45 GW which was also successfully met," the ministry said. It added: "This is the 3rd consecutive day of peak power demand reaching a new high."
The latest peak power demand is the 4th in less than a month and confirms a fast-tightening trajectory for the country's grid:
25 April 2026 — 256.1 GW
18 May 2026 — 257.37 GW
19 May 2026 — 260.45 GW
20 May 2026 — 265.44 GW
The 5 GW jump in a single day is among the sharpest day-on-day increases this summer. The last peak power demand of 260.45 GW recorded on May 19 had already been the third all-time high in 25 days. Now, Wednesday's number leaves the Power Ministry's 270 GW summer projection within touching distance.
In a post earlier this week, Union Power Minister Manohar Lal Khattar's office had said India was scaling new energy milestones with each successive peak, with the 256.1 GW, 257.37 GW and 260.45 GW records all met seamlessly without any shortage.
The records are being driven, almost entirely, by cooling demand. The India Meteorological Department's (IMD) May 18 special bulletin had flagged heatwave to severe heatwave conditions across the plains of northwest and central India through the week, with maximum temperatures forecast to climb a further 3-5°C over many parts of the northwest until May 21, a window that captures Wednesday's record peak.
On the ground, Bhatinda in Punjab, along with parts of Haryana and Rajasthan, crossed 46°C on Wednesday and Delhi recorded 45°C. The IMD has placed Rajasthan under heatwave warning until May 23, with Punjab, Haryana, Chandigarh and Delhi covered through May 18-24, and parts of Uttar Pradesh facing heatwave to severe heatwave conditions from May 19. The weather office has projected harsh summers overall and warned that the worst of May and June is still ahead.
The Centre, citing the IMD's above-normal heatwave forecast, has asked states and Union Territories to operationalise dedicated Heat Stroke Management Units at all health facilities and ensure adequate preparedness of ambulance services through the season.

Delhi's peak power demand had already touched a 2026 high of 8,039 MW at 3:35 pm on Wednesday, according to State Load Despatch Centre data, with officials estimating the capital's summer peak could cross 9,000 MW for the first time ever this year. The city crossed the 7,000 MW threshold as early as April 27, weeks earlier than the traditional May-June window.
