Searing heatwave temperatures in northern India pushed power demand to a record high, the government said Tuesday, with residents of the capital New Delhi also struggling with water shortages.

Much of northern India has been gripped by a brutal month-long heatwave, with temperatures regularly soaring above 45 degrees Celsius (113 degrees Fahrenheit).

Northern India has “been experiencing high demand conditions due to a prevailing heat wave” since May 17, the ministry of power said in a statement, adding it had been forced to import 25-30 percent more power from neighbouring regions.

“Despite these challenging conditions, the highest ever peak demand of 89 gigawatts in the northern region was successfully met” on Monday, it said.

India is no stranger to scorching summer temperatures but years of scientific research have found climate change is causing heatwaves to become longer, more frequent and more intense.
