California Builds First New Steel Mill in Over 50 Years: Mojave Micro Mill Advances Green Rebar Production in Kern County

Pacific Steel Group is constructing the Mojave Micro Mill in Kern County, marking California's first new steel mill in more than 50 years. Groundbreaking occurred in March 2025 on a 174-acre site near Mojave, with commercial operations targeted for late 2027. The facility will melt and roll rebar from locally sourced scrap metal, producing up to 450,000 tons annually while incorporating on-site solar power across 63 acres, carbon capture, and advanced emissions controls aimed at near-zero process carbon emissions.

The project has received a $30 million California Competes tax credit in exchange for over $540 million in committed investment and nearly 450 jobs in the first five years. Total project costs have risen to approximately $700 million (with some reports citing up to $800 million), driven by construction and materials expenses, though the timeline remains on track. Kern County approved additional property tax incentives potentially worth over $3 million, or roughly $7,500 per qualifying job.

Governor Gavin Newsom's office highlighted the mill's role in localizing supply chains for infrastructure like roads, bridges, and hospitals while advancing clean manufacturing goals. Company officials, including VP Mark Olson, emphasize it as the state's only integrated melt-and-roll steel plant, demonstrating that heavy industry can align with California's renewable energy mandates. Workforce development partnerships with local colleges are underway to train roles in welding, automation, robotics, and engineering.

The initiative stands out for blending traditional manufacturing revival with sustainability features, including scrap recycling that reduces out-of-state transport emissions and participation in state renewable and AB32 programs. Official environmental documentation and state announcements confirm the project's scale and green focus.
