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 a town resident, the Tonawanda Seneca Nation and the Sierra Club challenges the zoning agreement underpinning the park.

Timeline

  1. Stream wins approval for its initial project, later canceling those plans following a lawsuit from the Tonawanda Seneca Nation [2]

  2. Stream's initial STAMP proposal, a 900,000 sq ft facility with around 250MW of capacity, is presented at a public hearing [1]

  3. Tonawanda Seneca Nation, Sierra Club and a Town of Alabama resident sue the IDA and town officials over the STAMP incentive zoning agreement [6]

  4. Gov. Kathy Hochul signs executive order enacting a statewide moratorium on large-scale data centers, pausing permitting for up to a year [5]

Issues raised

  • The Tonawanda Seneca Nation has opposed the STAMP project, citing water and energy usage concerns [1]
  • The governor's executive order directs the Department of Environmental Conservation to hold data center permits and approvals in abeyance during a Public Service study, which Investigative Post reports appears to halt the proposal [5][6]
  • 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]
  • GCEDC's CEO said the development will pay for 100% of any electrical infrastructure needed for it [7]
