Arizona land developer Vermaland unveiled plans for a $33 billion data center industrial park that would become the largest such development in the United States.

The 3,300-acre complex on land between Phoenix and Tucson would support up to 3 gigawatts of power capacity. Vermaland’s project incorporates a hybrid energy system combining solar, natural gas, battery storage and grid connectivity for continuous operations.

The development sits within a federally designated Qualified Opportunity Zone in the Phoenix-Tucson corridor, offering investors tax advantages for long-term capital investments. Opportunity Zone projects can provide up to 15% reductions in capital gains taxes for investments held 10 years or longer.

Phoenix saw 67% in data center inventory growth in 2024, outpacing all primary markets except Atlanta.
