Sabey Data Centers is expanding its campuses in Washington and bringing new capacity online later this year.

The company this week announced 30MW of new capacity coming online at two of its Washington state campuses. Availability is aimed for Q4 2025.

In Seattle, 6MW of Tier III-standard critical power will come online by December 1, 2025.

At its Columbia campus in East Wenatchee, Washington, 5.5MW of Tier III-standard critical power will be available starting November 1, 2025. Sabey said the site has further room to grow, with 9MW coming online at the end of 2026 and another 9MW scheduled for the beginning of 2028.

“These two expansions reflect our continued investment in delivering sustainable, reliable, and scalable digital infrastructure across key US markets,” said Tim Mirick, president of Sabey Data Centers. “Whether customers are seeking lower total cost of ownership or world-class interconnection, our Columbia and Seattle campuses provide the flexibility and performance today’s enterprises need.”

A joint venture between Sabey Corporation and National Real Estate Advisors, Sabey Data Centers operates more than 4 million sq ft of data centers across the US, with six data center sites across the US in Quincy, Seattle, and East Wenatchee, Washington; New York City; Austin, Texas; and Ashburn, Virginia.

The East Wenatchee site, formerly known as the Intergate.Columbia campus, was originally announced in 2006, with the company leasing its first two buildings to T-Mobile and VMware. A 14MW expansion was announced in 2018.

Formerly known as Intergate.East, Sabey’s Seattle campus totals 54MW across 1.2 million sq ft across multiple buildings along S 120th Place in Tukwila. Originally developed by Sabey for (and then purchased by) Boeing around 1990, Sabey re-acquired the six-building campus in 1999. On its website, Sabey said 6MW of liquid cooling-ready capacity is scheduled to come online in late 2025.

Elsewhere in Washington, Sabey launched the Quincy campus – located at 2200 M St NE in Grant County – in 2011, with work on a second building beginning in 2015. It completed a two-building, 85MW expansion in 2023.
