Alert Issued

Following a July 2024 lightning arrestor failure on a 230-kV transmission line causing a rapid 1,500 MW load drop due to data center UPS systems switching to battery backup, NERC issued its third-ever Level 3 Essential Actions Alert in May 2026. The alert addresses the emerging grid threat posed by computational loads from data centers, which are growing rapidly and outpacing existing reliability

Description

Following a July 2024 lightning arrestor failure on a 230-kV transmission line causing a rapid 1,500 MW load drop due to data center UPS systems switching to battery backup, NERC issued its third-ever Level 3 Essential Actions Alert in May 2026. The alert addresses the emerging grid threat posed by computational loads from data centers, which are growing rapidly and outpacing existing reliability standards. The alert mandates immediate action from Transmission Planners, Transmission Owners, Balancing Authorities, and grid reliability coordinators across North America, with a reporting deadline of August 3, 2026, and enforcement starting in 2027 or 2028 with penalties up to $1 million per day per violation.
