A transmission line built to fix grid congestion has become Oklahoma’s hottest data center address
Data center developers are flocking to northwest Oklahoma City, specifically near the Mathewson Substation in Kingfisher County, due to a new $72 million transmission project that provides robust electrical grid access. This surge in interest from companies like Cloverleaf Infrastructure and Beltline Energy has prompted local opposition over community impacts and led to new state legislation to protect ratepayers and local moratoriums on new data center applications.
A new $72 million transmission line project at the Mathewson Substation, located in northwest Oklahoma City near Piedmont in southeastern Kingfisher County, has become a prime location for data center development. Two companies, Houston-based Cloverleaf Infrastructure and Atlanta-based Beltline Energy, are actively pursuing large-scale artificial intelligence data centers in the area, including Piedmont, Yukon, Oklahoma City, and Luther, drawn by the substation's robust connection to Oklahoma's power grid.
This influx of interest stems from the immense power demands of modern AI data centers, which can consume as much electricity as a small city. Electrical grid planners at the Southwest Power Pool (SPP) initially designed the Mathewson-Redbud transmission line to alleviate grid congestion, but it now inadvertently serves as a major draw for power-hungry industries. SPP projects a near-doubling of electricity demand in its 14-state region over the next decade, driven by data centers and electrification, prompting calls for new extra-high-voltage 'expressway' transmission lines.
However, the proposed projects have generated significant local opposition, with residents in communities like Piedmont, Yukon, and Luther raising concerns about project size, water usage, noise, traffic, and transparency, including issues with non-disclosure agreements signed by city officials. In response, Oklahoma City and Edmond have enacted temporary moratoriums on new data center applications while reviewing zoning and development standards.
State lawmakers have also addressed the issue, approving House Bill 2992, the Data Center Consumer Ratepayer Protection Act, to ensure large-load customers like data centers bear their infrastructure costs rather than shifting them to residential consumers, and requiring public notice for major developments. Additionally, Senate Bill 480 was passed to allow businesses to develop their own electric generation, potentially reducing strain on the public grid. These measures highlight how access to electrical infrastructure has become the primary factor in site selection for data centers, profoundly impacting economic development and grid planning in Oklahoma and across the central U.S.
