The owners of the former Tonawanda Coke plant, Jon Williams and John Yensan, plan a 500,000-square-foot data center development on the site with an unnamed data center developer, a proposed $2 billion investment. In June 2026 the developer paused its site plan and environmental (SEQRA) review with the Town of Tonawanda Planning Board while it waited on grid studies from NYISO and National Grid. Cleanup and demolition of the coke plant continue under New York's Brownfield Cleanup Program.
In August 2026 the town adopted a one-year moratorium on new large data center applications, a month after New York paused state permits for large new data centers. The Clean Air Coalition of WNY and local residents oppose the project. The coalition wants the site used for renewable energy generation and storage.
