Data Centers Clash With Communities as Heatwaves Strain Power Grids

The tension is reaching a breaking point in regions like the mid-Atlantic, where PJM Interconnection, the grid operator for 67 million people, has seen capacity prices surge by roughly 1,000% since 2024. In Henrico County, Virginia, officials are bracing for a 25% spike in electricity costs for public facilities, prompting local management to issue austerity measures that include dimming lights and disabling office equipment.

Behind these fiscal strains lies a deeper environmental cost. To prevent grid collapse, the U.S. Department of Energy has authorized data centers to deploy backup diesel generators. Environmental experts warn that these emissions, which the EPA identifies as possible carcinogens, are creating a public health crisis in areas like Lowell, Massachusetts, where residents report being trapped indoors by the smell of toxic fumes. With over 1,500 projects in the pipeline and at least 74 new natural gas-fired power plants planned to support them, critics like Alex Bomstein of the Clean Air Council argue that the industry is prioritizing rapid expansion over the health and stability of the communities it inhabits.
