Eastern US power grid operator orders emergency curbs as electricity use nears recordUS' largest power grid PJM orders emergency curbs as electricity use nears record peak

The US power grid operator PJM ordered emergency electricity curbs on July 3 as electricity use approached a record peak across the East Coast and Midwest.

The operator faced generator outages and overloaded transmission lines during a period of surging air-conditioning demand driven by a heat wave. This event highlights the vulnerability of the national energy infrastructure to extreme weather and rising consumption.

  • The PJM grid serves approximately 61 million people across 13 states.
  • Record electricity demand in the US often coincides with the summer months of July and August.
  • Extreme heat can reduce the efficiency of power transformers, contributing to grid overload.
