Bitdeer Weathersfield Township data center (former Niles power plant site)

Weathersfield Township, Trumbull County, OH

Bitdeer Weathersfield Township data center (former Niles power plant site) is an announced data center project in Weathersfield Township, OH, backed by Bitdeer Technologies Group. Singapore-based Bitdeer Technologies Group acquired the former Niles power plant property in Weathersfield Township, Trumbull County (May 2025) and says plans remain on track to 'energize' the site by early 2029, though the company has not publicly disclosed the intended use. Weathersfield Township trustees stated in April 2026 that current zoning does not allow a data center on the site, creating a zoning obstacle. Community organizing locally under the 'Dragons Against Data' Facebook group (Niles-area).
