Destenie Nock: This summer, your air conditioner is going to compete with a data center

Western Pennsylvania is experiencing a substantial surge in data center development, with billions of dollars in investments announced across locations like Springdale, Homer City, Shippingport, and Upper Burrell. The scale of these facilities is significant; just three planned sites could consume enough electricity to power almost all of the 5.8 million homes in Pennsylvania. The central concern highlighted is the massive electricity demand these data centers place on the grid, especially during peak times like summer heat waves when cooling systems for servers compete with residential air conditioning. This increased demand has led to a nearly tenfold jump in capacity prices for PJM Interconnection, the regional grid operator, between 2024-25 and 2025-26 delivery years. An independent market monitor attributed roughly two-thirds of this increase to data center demand, adding an estimated $9.3 billion in costs that translate directly into higher household electric bills across the 13 states PJM serves, including Pennsylvania. Residents have already seen rate increases of 10% to 20%. In Springdale, residents opposed a 565,000-square-foot data center project that would draw up to 180 megawatts, but the borough council approved it 5 to 2, citing state law requirements. Destenie Nock, a researcher at Carnegie Mellon University, emphasizes the lack of analysis regarding the projected impact of data center projects on monthly bills for nearby households. While recognizing Governor Josh Shapiro's support for data centers that bring their own power or cover grid strain, Nock argues for a mandatory, household-level cost analysis for the surrounding area before any new data center project receives approval, ensuring transparency about the financial burden on ordinary families.
