Heat Wave Heightens Strain on Lowell Data Center and Community Concerns
Rising temperatures in the eastern United States are increasing electricity demand for a Lowell, Massachusetts data center, prompting worries about grid stress, air quality and local opposition.
Extreme heat across the eastern United States is boosting electricity consumption at a data center in Lowell, Massachusetts, adding pressure to the regional power grid and raising air-quality concerns for nearby residents. The facility, operated by the Markley Group, relies on water-intensive cooling and, during peak demand, may activate backup diesel generators, which emit pollutants.
"I think about the air quality, the water, what effects it has on the kids in the area," said 82-year-old resident Eileen Castle, who lives near the center.
State Representative Tara Hong highlighted that the neighborhood, designated as facing higher environmental and health risks, is largely low-income and working-class. She noted that the data center sits amid this community.
University of California, Riverside professor Shaolei Ren described heat waves as a particularly challenging condition for data-center operation, noting that generators are used only as a last-resort measure when the grid is stressed. He warned that extensive generator use could worsen local air quality.
Markley Group CEO Jeff Markley said the company has planted more than 2,000 trees nearby and that generators are run only during actual power disruptions, with brief weekly tests and one unit operating at a time.
Researcher Jonathan Koomey said national data-center electricity growth has been moderate, but local impacts can include higher energy use, traffic and other environmental costs. He explained that large facilities must coordinate their power draw to avoid simultaneous spikes that could threaten grid stability.
The North American Electric Reliability Corporation has issued guidance on managing the risks posed by large AI-related data centers.
Community tensions surfaced at a city-led forum, where a 14-year-old participant was briefly detained after expressing opposition to further data-center expansion. Mayor Erik Gitschier defended the police action as a measure to maintain order during a heated discussion.
In February, Lowell’s City Council voted unanimously to impose a one-year moratorium on additional data-center development, reflecting ongoing local concerns.
