As summer begins, power demand is emerging as the key market indicator to watch across U.S. regions. Grid operators are preparing accordingly, signaling that while reliability is expected under normal conditions, the margin for error is narrowing as load growth accelerates.

In Texas, ERCOT’s summer weather outlook calls for near-normal temperatures and normal to below-normal rainfall. However, it also notes that a “normal” summer in Texas would still rank among the warmest summers on record, underscoring that elevated cooling demand remains a baseline expectation.

PJM projects demand is forecasted to peak around 156,400 MW, and while it expects sufficient capacity under typical conditions, it notes that tightening reserve margins may require demand response and other grid-balancing measures during periods of system stress (PJM Summer Outlook). The National Weather Service is forecasting warmer-than-normal conditions across much of the PJM footprint this summer, especially in the mid-Atlantic and southern regions, while much of the Midwest is expected to see more typical temperatures.

Weather remains a key variable. The latest outlook from NOAA’s Climate Prediction Center indicates above-normal temperatures are likely across parts of the southern U.S. and Gulf Coast, which can increase cooling demand and elevate peak load risk.
