Updates, newest first

  1. Sept. 30, 2026 NYISO's queue lists two 300 MW data center load requests for the STAMP substation by GCEDC, marked under construction. (New York Independent System Operator (NYISO), Sept. 30, 2026)
  2. July 15, 2026 Investigative Post reported it was unclear whether the governor's permit pause applies, since DEC had not yet accepted the project's stormwater plans; GCEDC had not voted on the incentives. (Investigative Post, July 15, 2026)
  3. July 14, 2026 The Tonawanda Seneca Nation, the Sierra Club and a town resident sued in State Supreme Court to void the 2012 zoning agreement between the Town of Alabama and GCEDC that governs the site. (Sierra Club Niagara Group, July 14, 2026; Investigative Post, July 15, 2026)
  4. April 16, 2026 GCEDC held a second public hearing in Alabama; opponents included the Tonawanda Seneca Nation and environmental groups, while building-trades unions spoke in favor. (The Batavian, April 17, 2026)
  5. March 18, 2026 Investigative Post reported the requested tax breaks at about $1.46 billion, mostly sales tax on equipment, for about 125 permanent jobs. (Investigative Post, March 18, 2026)
  6. March 2026 A revised application raised the planned investment to $19.46 billion, with 2.2 million sq ft in three two-story buildings. (DatacenterDynamics, March 9, 2026)
  7. Dec. 18, 2025 The GCEDC board voted to act as lead agency for the environmental review of the expanded project; the Tonawanda Seneca Nation had asked the state DEC to take that role instead. (The Batavian, Dec. 19, 2025)
  8. Sept. 2025 Stream withdrew the first plan; GCEDC later rescinded its approvals after Stream announced a larger project. (The Batavian, Dec. 19, 2025)
  9. March 6, 2025 The Genesee County Economic Development Center (GCEDC) approved Stream's first, smaller plan: 900,000 sq ft and 250 MW on 59 acres. (The Batavian, Dec. 19, 2025)

Conflicts and open questions

  • Site size is given as 90 acres (Investigative Post, Sierra Club) and 130 acres (DCD, The Batavian); both are reported.
  • Total tax-break figure has risen with each application: $472 million, about $800 million, then about $1.46 billion.
