Micron’s $100B New York Megafab Hits the Brakes

Micron has postponed construction of its $100 billion semiconductor megafab in Clay, New York, by two to three years, according to the project’s final environmental impact report. 

The first fabrication plant is now expected to open in the third quarter of 2030, with subsequent fabs scheduled through 2041.

“Based on construction timelines experience across the semiconductor industry for greenfield fabs in the United States, Micron has updated our projected operational milestones,” the company said in a statement to NewsChannel 9 WSYR Syracuse. 

“We are well-positioned to proceed with confidence.”

Early site work has begun at White Pine Commerce Park, a 1,300-acre site north of Syracuse, with Gilbane handling preconstruction after being awarded the contract in August. 

Onondaga County Executive Ryan McMahon attributed the delay to “longer construction cycles and labour shortages,” telling local reporters the timeline adjustments were “normal for such a large project” and would allow Micron greater flexibility.

The megafab campus will include four DRAM fabs as well as supporting facilities such as childcare, healthcare, and recreation centers.

The childcare center’s construction has been pushed back from 2026 to 2028, while the healthcare and recreation facilities are now scheduled for 2032 to align with when employees begin arriving.

Even with delays in New York, Micron is speeding up work at its Boise, Idaho, plant. Around $1.2 billion in federal support originally intended for Clay has been redirected to the Idaho facility. 

Construction of the first plant will now start in the second quarter of 2026, the second plant will run from the fourth quarter of 2030 to the fourth quarter of 2033, and the third plant is delayed by two years to the third quarter of 2035. The fourth plant is also postponed by one quarter.

The Department of Commerce awarded up to $6.165 billion under the CHIPS Incentives Program to support Micron’s US megaprojects.

The environmental report found that the new construction schedule wouldn’t greatly change the project’s environmental effects and might even reduce them a little. The groundbreaking ceremony for the Clay site is still planned for December 2025.
