KEY POINTS
-
The New York State Public Service Commission approved a plan to build a two-mile, 345-kilovolt underground transmission line connecting a power substation to Micron’s future massive semiconductor manufacturing campus.
-
The transmission infrastructure, featuring eight high-voltage underground laterals, will power Micron’s planned semiconductor fabrication facilities at the 1,400-acre White Pine Commerce Park.
-
The $100 billion Micron project is anticipated to create 9,000 direct jobs, tens of thousands of union construction jobs, and drive regional economic output to over $16 billion by 2041.
The $100 billion Micron Technology semiconductor fabrication project has reached a major milestone. The New York State Public Service Commission (PSC) approved National Grid’s petition to construct a two-mile, 345-kilovolt underground transmission service line.
Governor Kathy Hochul announced the progress in a statement last week. The transmission line will connect an existing Clay, NY, substation to the future semiconductor fabrication areas on the White Pine Commerce Park campus in Onondaga County.
Micron Project: Massive, Multi-Year, Megafab
The approval for the transmission line is a critical piece of infrastructure for Micron New York Semiconductor Manufacturing. It plans to build a large-scale semiconductor manufacturing complex, or megafab (definition below), at the 1,400-acre White Pine Commerce Park in Clay, Onondaga County.
Micron has stated it expects to build its NY megafab with up to 2.4 million square feet of clean room space for the manufacture of semiconductors at the campus.
Semiconductor megafabs are large-scale semiconductor manufacturing facilities designed for high production output. They are massive factories capable of starting production on roughly 80,000 or more semiconductor wafers per month. Megafabs are designed to improve efficiency, reduce costs, and streamline management by consolidating production, engineering, and resources in one location.

The project will include up to four semiconductor fabrication facilities (or fabs) and supporting infrastructure such as utility buildings, stormwater systems, access roads, parking areas, a childcare center, and a rail spur to the west.
Construction is anticipated to proceed from west to east, resulting in ongoing development across the Micron campus from 2025 through 2041.
Power to the Project
The PSC also approved National Grid’s environmental management and construction plan for the first phase, which includes the eastern expansion of the Clay substation and installation of equipment linking the substation to the Micron campus.
The joint proposal was signed by National Grid, the New York State Department of Public Service staff, and the New York State Department of Environmental Conservation.
