Vermaland La Osa: $33B 3GW Mega-Scale Data Center Pinal County

Status: Planning / Rezoning Phase (Land Use Amendment Approved Nov 2025)   |   Location: Vermaland, 3,374-Acre Site along Greene Canal, south of Eloy

Project Overview

Officially unveiled in August 2025 and progressing through regulatory and planning approvals as of March 2026, the La Osa Project represents one of the most ambitious digital infrastructure initiatives in the American Southwest. Located between Phoenix and Tucson, the $33 billion development is designed to create a large-scale “Data Center Corridor” connecting the two major metropolitan areas. The project spans an extraordinary 3,374 acres and is planned to deliver approximately 3 gigawatts of IT capacity once fully built out. To put this into perspective, that capacity would exceed the entire currently operational data center footprint across the Phoenix metropolitan region, highlighting the project’s unprecedented scale and its potential to reshape the regional digital infrastructure landscape.

A core challenge for hyperscale developments of this magnitude is securing sufficient power supply. To address this “power gap,” the La Osa Project is designed around a hybrid energy strategy. During its early development phases, the campus will rely on a dedicated natural gas–fired power plant paired with large-scale Battery Energy Storage Systems (BESS) constructed across roughly 480 acres. These systems will provide reliable baseload electricity and grid stability for the first generation of facilities. Over time, however, the development is expected to transition toward a fully renewable energy model, drawing power from Vermaland’s extensive solar portfolio spanning approximately 10,000 acres of photovoltaic installations. This phased approach allows the project to support immediate hyperscale demand while aligning with long-term decarbonization goals.
