AI Data Centers Are Causing ‘Distortions’ in the Power Grid from Coast to Coast

December 31, 2024

According to an analysis conducted by Bloomberg, the rapid growth of AI data centers across the United States is not only putting a strain on the power grid, but also distorting the quality of power delivered to homes, increasing the threat of damage to appliances and fires. increasing the risk of

recent report By Bloomberg argues that the explosive growth of artificial intelligence is putting an unprecedented strain on the U.S. power grid, and it's about more than just keeping the lights on. A new analysis by Bloomberg, using data from Whisker Labs and DC Byte, shows that the proliferation of AI-supported data centers will reduce the amount of electricity supplied to millions of homes across the country, especially in areas like Chicago and Northern Virginia. It is shown that the quality is distorted. central alley. ”

Known as “bad harmonics,” this problem occurs when the normal flow of electricity in a standing wave is disrupted, causing abnormal spikes or dips in voltage. Whisker Labs, which tracks power quality using nearly 1 million residential sensors, estimates that more than three-quarters of the most severely affected homes are within 80 miles of significant data center activity. I discovered something.

Continued exposure to distorted power can cause appliances to overheat, rattle the motors in appliances like refrigerators and air conditioners, and cause billions of dollars in damage over time. But experts warn that bad harmonics are just the tip of the iceberg, a harbinger of deeper problems engulfing the country's electricity infrastructure.

“Harmonics are a great canary in a coal mine for early signs of stress and problems,” said Bob Marshall, CEO of Whisker Labs. Left unchecked, power quality issues can snowball into voltage surges that cause fires or sudden voltage sags that cause power outages.

At the heart of the crisis is the insatiable appetite of data centers, which can consume 10,000 times more electricity than a single household. In the United States, which operates the most data centers in the world, electricity demand is expected to surge 16% over the next five years, driven largely by new data centers, three times what was predicted last year.

This is putting strain on power grids that are already strained by aging infrastructure, extreme weather events, and the electrification of transportation and heating. But electricity use has remained roughly flat to date, and investment in the grid has been delayed for decades.

The fallout is evident in Chicago, where more than a third of sensors consistently exhibited harmonic distortion, and Northern Virginia, a global data center hub, where facilities are operating or expanding. distortion exceeded industry tolerance limits.

While urban centers are bearing the brunt, data centers are also impacting rural America. Bloomberg's analysis found that regardless of population density, sensors closer to data centers consistently pick up more distorted power than sensors further away.

Experts say there can be multiple causes behind bad harmonics, from industrial machinery to renewable energy inverters. However, the strong correlation between data center proximity and poor power quality shows that it plays a huge role.

Several remedies have been introduced, such as dedicated electrical substations and power filtering devices. However, the inability of most power companies to closely monitor power quality on a home-by-home basis remains a major hurdle due to prohibitive costs. As a result, distortions that negatively affect household appliances often go unnoticed until they spread.

“The contract with the utility company has built-in the right to receive a certain quality of power,” said Hasara, a researcher at North American Electric Reliability Corporation, which studies the impact of data centers on the power grid. Dharmawardena says. “We need to make sure we measure that and make sure consumers get the power quality they deserve.”
