A new report has highlighted the significant impact that the increasing power demands of artificial intelligence (AI) data centres are having on electricity quality for millions of Americans. According to Bloomberg, these facilities are consuming so much power in numerous major metropolitan areas that the electricity received by local residents is deteriorating.
The disruption is reported to manifest as "bad harmonics," a condition where distortions in the electrical waves affect the delivery of power to homes. These distortions can lead to appliances overheating and malfunctioning. To illustrate the scale of this issue, Hasala Dharmawardena, a senior engineer with the North American Reliability Corporation, described the load generated by a data centre as akin to "taking your house and increasing that by 10,000," emphasising the enormity of these facilities compared to standard domestic consumption.
Bloomberg’s analysis of data from hundreds of thousands of home sensors indicates that many distorted power readings are concentrated within 50 miles of AI data centres. This situation raises concerns not only about the adequacy of electricity supply for everyday use but also about the potential physical risks to residents, such as appliance failures leading to power surges or even electrical fires.
Further compounding the issue, a study by Grid Strategies, a consulting firm based in Washington D.C., predicts a 16% increase in electricity demand in the U.S. by 2030, fuelled by the expanding AI industry. This projected demand surge is over three times the estimate for 2023, indicating that without substantial investment in strengthening the existing electric grid infrastructure, the issue of power distortion and its associated risks is likely to intensify.
Metro areas identified as having the highest concentration of AI data centres include Northern Virginia, the Dallas-Fort Worth region, the San Francisco Bay Area, Phoenix, Atlanta, and Chicagoland. In light of these developments, leaders in energy management are calling for greater awareness and understanding among decision-makers regarding the risks posed by these growing power demands. Bob Marshall, CEO of Whisker Labs, points to harmonics as an early indicator of stress within electrical systems, remarking, "Harmonics are a pretty good canary in the coal mine for early signs of stress and problems."
As the conversation around AI and its infrastructural requirements evolves, the implications for residential power quality continue to emerge as a critical area of concern.
