DOE directs data centers to activate backup generators amid extreme heat

The Energy Department issued a directive for data centers to activate their backup power sources. The order comes as triple‑digit temperatures spread across much of the United States. Officials say the extreme heat threatens grid stability and data center operations. The Trump administration is urging grid managers to enforce the use of these generators. Many facilities have backup systems that sit idle under normal conditions. Activating them now is intended to reduce strain on the electric grid. The move aims to prevent outages that could affect critical online services. Industry groups will need to comply and report usage to the department.
