Impact & Risks

The record-breaking electricity demand highlights the growing strain on the U.S. power grid, driven by extreme heat, increased electrification, and rising data center usage. PJM, ERCOT, and SPP issued multiple reliability advisories and emergency alerts during the summer, with some regions approaching rolling blackout conditions.

Rising wholesale electricity prices, particularly in PJM, are expected to increase retail costs, adding financial pressure on consumers.
