Data Centers and Environmental Concerns in Lowell

In Lowell, Massachusetts, Eileen Castle, 82, has decided not to fill her swimming pool this summer. The data center behind her home has made her cautious. The industrial air conditioners and diesel generators create noise and fumes, impacting air quality.

Hot weather increases electricity demands on data centers, straining power grids and affecting air quality in neighborhoods. The Sacred Heart area, known for its diverse population, faces higher environmental and health risks.

State Representative Tara Hong pointed out the community’s struggle. Many residents work hard to support their families, and the data center’s presence adds to their challenges.

Data Centers and Resource Use in Heat Waves

Data centers have heavy resource needs during heat waves. Shaolei Ren, a professor at the University of California, Riverside, noted the dual methods to cool servers: energy-intensive refrigeration-based cooling and water-intensive evaporative cooling. Data centers sometimes rely on backup diesel generators to prevent outages, posing risks to local air quality due to emissions.

The Markley Group, which operates the Lowell data center, stated its generators activate only in emergencies. To mitigate environmental impact, the company has planted over 2,000 trees nearby. CEO Jeff Markley emphasized that generator use is minimal.

From Pasta Factory to Data Center

The Lowell data center site was once an abandoned pasta factory. The area’s water supply, from the Merrimack River, made it a prime location. The facility uses about 118,000 gallons per day in summer. This is a small percentage of the city’s overall water consumption.

Castle initially welcomed the Markley Group. However, tensions arose with additional expansions, leading to increased surveillance and cooling systems next to her residence.

In response to community concerns, Lowell’s City Council has enacted a one-year moratorium on new data center expansions. Jonathan Koomey, a researcher, argued that data center electricity demand has increased locally but not on a national scale. Yet, local issues like environmental and economic costs remain significant.

Heat and Power Concerns

With rising temperatures, power grid strain increases. Large data centers intensify this strain differently from home air conditioning systems. Operators must coordinate usage to prevent simultaneous power demands.

The North American Electric Reliability Corporation recently highlighted challenges from growing power demands due to AI data centers. Guidelines were issued to address immediate risks.

Community Tensions and Data Centers

In Lowell, data center zoning discussions have heated up. Police temporarily detained a 14-year-old who interrupted a community forum. Mayor Erik Gitschier explained his actions, emphasizing the need for orderly debate on the contentious issue. The community remains divided on the data center’s impact on local life.
