Coal Creek Data Center

Underwood, McLean County, ND

Coal Creek Data Center is an announced data center project in Underwood, ND, backed by Rainbow Energy Center LLC. McLean County rezoned roughly 800 acres of land near Rainbow Energy Center's 1,151 MW Coal Creek Station (between Underwood and Washburn) from agricultural to commercial use to enable future data center development, reportedly for facilities drawing power directly from the coal plant. As of the most recent reporting no specific data center building on this land has been constructed or become operational; this is a developmental/planned industrial park, not an operating facility. [Reviewed 2026-10-09: verified] McLean County Commission approved rezoning of 800 acres near Coal Creek Station for data center development; Rainbow Energy has announced plans for up to 300 MW data center capacity on the site, though no specific facility has been constructed or become operational.
