Overview

The Largest Campus on US 79

PowerCampus Austin, at 4200 County Road 132 in Hutto, is Skybox Datacenters and Prologis's campus on 159 acres of the 1,400-acre Hutto Megasite: up to 600 MW through two dedicated 300 MW Oncor substations, and up to 4 million sq ft in six to eight buildings. It is the largest data center on the US 79 Data Center Corridor, with at least $10B committed through 2030 and beyond.

Its power comes off the transmission Oncor built for Samsung Taylor: a 345 kV line runs beside the site, and Oncor and LCRA own about 70 adjacent acres. The first building is fully leased to an undisclosed tenant; the first three were tracked for early 2026. Williamson County granted a Chapter 312 abatement of 50% on personal property above a $100M minimum.

Phase 2

Project Sequel

Skybox and Prologis are in early planning on Project Sequel, about 140 acres just west of PowerCampus. Its scale is not public; if it matches the first campus, Skybox and Prologis capital in Hutto would pass $20B, the largest committed data center buildout on the corridor.

The Prologis engine

One Site in a 5.8 GW Pipeline

Prologis, the world's largest industrial landlord with 1.3 billion sq ft in 5,881 buildings and a 14,000-acre land bank, grew its data center power pipeline to 5.8 GW by mid-2026, more than double in two years, with 85% set to start by 2030. CFO Tim Arndt says every megawatt it can deliver in the next three years is already in talks with a hyperscaler. Development starts reached $2.1B by mid-2026, and full-year guidance rose to $5.5B to $6.5B.

The Skybox partnership, formed in 2021, gives Prologis data center development skill without building its own division; Prologis brings the land and scale. Compass co-founder Chris Curtis has led the Prologis data center effort since 2024.
