Stream U.S. Data Centers proposes a three-building data center campus over 90 acres at the 1,250-acre STAMP industrial park in the Town of Alabama, with a 2.2 million sq ft building footprint and 500 megawatts of electricity use. Stream amended its proposal from $11 billion to $19 billion in total spending, and Genesee County Economic Development Center officials are offering $1.46 billion in tax breaks for 125 jobs. A July 2026 executive order by Gov. Kathy Hochul placed a moratorium on new data center approvals that appears to halt the proposal, and a lawsuit by the Tonawanda Seneca Nation, the Sierra Club and a town resident challenges the zoning agreement underpinning the park.

Issues raised

  • As of May 2026, neither the Town of Alabama Planning Board nor GCEDC had made a decision on the proposal [3]
  • New York lawmakers passed a one-year moratorium on new data centers with peak demand of 20 megawatts or more in June 2026 [4]
