Skybox/Prologis PowerCampus

PowerCampus Austin in Hutto is the largest data center on the US 79 corridor and one of the most scalable in the country — up to 600 MW through two private Oncor substations, with as much as 4 million square feet across six to eight buildings at full buildout. It is the anchor tenant of the corridor's data center concentration, and one node of a Prologis buildout strategy that is itself accelerating.

What it is

PowerCampus Austin occupies 159 acres within the 1,400-acre Hutto Megasite along US 79. Its defining feature is power: two dedicated 300 MW Oncor private substations give the campus a 600 MW baseline, drawing on the transmission infrastructure Oncor built to serve Samsung Taylor — the corridor's structural advantage. The first building is fully leased, with the first three tracked for early 2026 delivery per Skybox development leadership, and building-level TDLR filings have moved steadily: $86M site improvements, a $149M shell completion, a $125M Building 2 interior fit-out (235,730 sq ft, 24 MW IT), and a $60M second shell. Total minimum investment exceeds $10 billion through 2030 and beyond.

The Prologis engine behind it

PowerCampus is one site inside a much larger machine. Prologis — the world's largest industrial real estate owner, with 1.3 billion square feet across 5,881 buildings and a 14,000-acre land bank — has built data centers into a decade-long strategy. Its data center power pipeline reached 5.8 GW by Q2 2026, more than doubling in two years, with 85% positioned for project starts through 2030 and, per CFO Tim Arndt, every deliverable megawatt over the next three years already in discussion with a hyperscaler. Year-to-date development starts hit $2.1 billion through Q2 2026, exceeding the prior full-year target, with 2026 guidance raised to $5.5–6.5 billion.

The Skybox partnership, formed in 2021, is how Prologis moves fast without building an internal data center division from scratch: Skybox supplies the data center development expertise, Prologis the land and structural scale. The partnership has deployed across Plano, Pflugerville (Skybox Austin 1), Elk Grove (Illinois), and a newly announced PowerCampus Dallas in Lancaster, with Compass co-founder Chris Curtis leading Prologis's data center effort since 2024. Hutto is its largest single campus.

Project Sequel

Skybox and Prologis are in early planning on Project Sequel — a prospective 140-acre Phase 2 just west of PowerCampus Hutto. Scale and details are not public, but the site coordination points to an expansion comparable to the existing campus, potentially another $10 billion-plus and additional multi-hundred-megawatt capacity. Combined committed and prospective Skybox/Prologis Hutto capital would exceed $20 billion, which is what makes this the single largest committed data center buildout on the corridor.

Corridor position

PowerCampus is the largest of the four US 79 corridor campuses and the clearest beneficiary of the Samsung Oncor effect — 600 MW of committed capacity that exists because the transmission was pre-built for the fab. Per Cushman & Wakefield data through early 2026, the wider Austin–San Antonio corridor holds roughly 7,800 MW of planned capacity against about 1,150 MW operating; within it, Hutto is the single largest committed buildout. It sits alongside Colovore in Hutto and Blueprint in Taylor and Georgetown, all on the same inheritance-based logic that makes US 79 the Austin Supercluster's data center spine.

ASML's EUV field-support facility for Samsung Taylor is located less than 3 miles away at the Hutto Co-Op.
