- NERC oversees grid reliability in the US, Canada, and parts of Mexico.
- The agency issued a Level 3 alert this week regarding risks posed by data centers.
- AI training can cause wild power swings, threatening grid stability.
Data centers are increasing the risk of power outages and blackouts — and electric grid operators aren’t prepared to handle it.
The North American Electric Reliability Corporation — the top grid oversight agency for the US, Canada, and parts of Mexico — issued a rare alert on Monday, urging operators to address new risks posed by the deluge of data centers connecting to the grid.
NERC issued the Level 3 alert for “essential action” — the agency’s highest level — after issuing two previous warnings about data centers in the last nine months.
The agency sends alerts to the entities that make the electric grid run smoothly, from regional transmission organizations to power plant owners.
This time, the agency stressed that grid operators lack “sufficient processes, procedures, or methods to address risks associated with computational loads.”
NERC says that data centers — particularly ones running AI workloads — are prone to wild power swings.
The constant, rapid fluctuations between extremely high and extremely low power use levels can put entire electric grids at risk of going offline.
Power swings “can occur in seconds, leaving ‘little or no room for real-time responses,'” the report said.
It’s not only AI training causing the instability. In its report, NERC said crypto mining and traditional data centers threaten the grid.
NERC asked grid operators to take immediate action and file risk mitigation plans with the agency by August 3.
“As the grid faces unprecedented challenges from a surge in large power consumers, NERC is taking significant steps to ensure the reliability of the bulk power system,” the agency said in a press release on Monday.
