STACK Infrastructure Plans Major Capacity Expansion at Portland Data Center Campus

According to a recent LinkedIn post from STACK Infrastructure, the company is planning significant growth at its flagship Portland, Oregon data center campus. The post indicates 25MW of new capacity is expected to be available in Q4 2027, with a further 96MW of expansion capacity beginning in 2029.

The LinkedIn post highlights that the site benefits from committed power and access to trans-Pacific cables and key West Coast markets. The message also suggests that this capacity is positioned as a phased path to scale in what is described as one of the nation’s most capacity-constrained markets.

For investors, the planned capacity additions could imply a multi-year growth runway in a strategically important data center hub. Access to subsea cable connectivity and major coastal markets may enhance the campus’s attractiveness to hyperscale and large enterprise customers, potentially supporting long-term utilization and pricing power.

The post’s emphasis on the increasing difficulty of securing comparable capacity points to tightening supply dynamics in the Hillsboro and broader Portland area. If demand for high-density, well-connected data center space continues to rise, STACK Infrastructure’s early commitment to expansion in this location could strengthen its competitive position in U.S. digital infrastructure.

The extended timeline, with major capacity coming online between 2027 and 2029, also suggests a capital-intensive build-out that will likely require disciplined project execution. Investors may view the phased approach as a way to align capital deployment with contracted demand, mitigating overbuild risk while maintaining optionality in a constrained market.
