New York approves buried power line for Micron’s $100 billion semiconductor facility
CLAY, N.Y. (UI) — New York Governor Kathy Hochul announced that the New York State Public Service Commission (PSC) has approved construction of a two-mile, 345-kilovolt underground transmission line connecting National Grid’s Clay substation to Micron Technology’s planned semiconductor megafab in Onondaga County.
The PSC also approved National Grid’s environmental and construction plans for the first phase of work, which includes upgrades at the Clay substation and installation of related transmission equipment. The decision marks a major milestone in preparing Central New York’s infrastructure for what will be the largest private investment in state history — Micron’s $100 billion megafab project.
“Today’s decision by the PSC marks a major milestone for the development of the Micron project in upstate New York,” Hochul said. “This project is set to transform Central New York — and we’re moving quickly ahead with all due speed and deliberation.”
The underground power line will deliver high-voltage electricity to the future fabrication site while limiting above-ground disruption in residential and environmentally sensitive areas. State officials said the plan includes strict environmental protections for waterways and wildlife, as well as post-construction restoration requirements.
The PSC’s approval reflects coordination between National Grid, the Department of Environmental Conservation, and local agencies. “For a project as large and transformational as Micron’s, every government agency involved must play its part to ensure its success,” PSC Chair Rory Christian said.
Once complete, Micron’s megafab is expected to create more than 50,000 jobs, including 9,000 at the facility itself, and will feature the nation’s largest clean-room complex — about 2.4 million square feet. The facility will rely on expanded renewable and carbon-free energy sources under the state’s Green CHIPS program.
Officials said the approval helps keep the project on schedule toward its planned 2030s operational timeline, with Micron’s presence expected to add billions to Central New York’s annual economic output.
