Heat dome poses woes for largest US power grid beyond data center boom

PJM, the largest U.S. power grid, expects record electricity demand driven by a heat dome and data center growth, and is re-routing power to prevent outages. To manage the stress, PJM may dispatch more expensive fossil-fuel generation, implying higher near-term power costs and operational risk despite no specific outage reported.
