Seattle-based wholesale colocation provider Sabey Data Centers has started work on a new facility at its Intergate.Columbia campus in East Wenatchee, Washington.

Building D will span 140,000 square feet (13,000 sq m) across four data halls, each with 3.6MW of mission critical power, for a total of 14.4MW. Scheduled for May 2019, it will join the already completed buildings A and B, as part of a long-term plan to have eight buildings at the campus.

Cheap power, low taxes

“Intergate.Columbia’s competitive advantages include $.025/kWh power rate which is among the lowest in the world,” Robert Rockwood, Sabey’s president, said.

“It is renewable hydropower drawn from the nearby power grid, delivering electricity efficiently, with little line loss, through the on-site substation. In addition, Central Washington’s mild, dry climate provides essentially free cooling for more than 90 percent of the year.”

Customers are also able to take advantage of the state Rural Data Center Tax Incentive program, which offers a sales tax exemption on IT equipment and installation services.

The Intergate.Columbia campus was originally announced in 2006, and the company leased its first two buildings to T-Mobile and VMware. It currently offers 438,000 square feet (40,700 sq m) of data center space.

The site is located just 30 miles from Sabey’s Intergate.Quincy campus, which Rockwood said “provides connectivity with negligible latency between the two locations - a tremendous resiliency play for customers seeking a business continuity strategy.”

Late last year, the company closed a $675m financing round - with $250m set to be spent on expansion. Then, in February, it entered into an alliance with Telehouse to provide shared services across North America, Europe, Asia and Africa.
