New York Governor Kathy Hochul announced Thursday that the New York State Public Service Commission has approved a new underground transmission line to connect the Clay substation with Micron Technology’s proposed semiconductor megafab in Onondaga County, marking a major step forward for one of the state’s largest-ever economic development projects.

The two-mile, 345-kilovolt line will provide critical power infrastructure for Micron’s planned $100 billion semiconductor complex in Central New York — a project Hochul called “the largest private investment in the state’s history.”

According to the governor’s office, the project is expected to create more than 50,000 jobs over the next 20 years, including 9,000 direct positions at Micron’s new chip manufacturing facility.

“This transmission project is another milestone in delivering on our vision to make New York a global hub for semiconductor manufacturing,” Hochul said in a statement. “We’re building the infrastructure that will power tens of thousands of good-paying jobs and strengthen America’s supply chain for generations to come.”

The new power line will be developed in partnership with National Grid, ensuring the megafab has access to reliable, high-capacity electricity essential for advanced chip production. Construction of Micron’s Central New York campus — part of a broader U.S. initiative to boost domestic semiconductor output — is expected to begin in the coming years, with initial production targeted before the end of the decade.

Micron’s investment is supported by federal incentives under the CHIPS and Science Act, as well as extensive state and local commitments aimed at revitalizing the region’s manufacturing base and positioning New York as a key player in the global semiconductor supply chain.
