Norwegian data center and colocation provider Bulk Infrastructure has begun the expansion of its Oslo Internet Exchange facility (OS-IX) in Norway.

The expansion will see three new data halls built, adding 5.5MW of IT capacity.

The company said this will bring the total capacity of the facility to more than 10MW and will make OS-IX the largest data center in the Oslo metropolitan area.

“We have designed the expansion of OS-IX with high-density workloads in mind, to be ready for both AI and HPC requirements, as well as more traditional data center services. Both AI, HPC, and traditional customers will benefit from OS-IX being Norway’s most connected data center, with a high number of global network operators present to help our customers execute their business,” said Rob Elder, chief commercial officer at Bulk.

He added: “We now have the capacity to support customers grow their new and existing platform. OS-IX provides a unique combination of high-density capacity in a metropolitan location.”

After completing the expansion, Bulk said it still has access to additional power and space to facilitate further expansion if required.

Bulk added that customers at OS-IX are provided low energy costs through a partnership between Bulk and a regional energy supplier.

Bulk first took full ownership of the OS-IX data center in January 2022, purchasing the remaining 50 percent shares it didn't own from Akershus Energi, a Norwegian hydroelectric power firm. The two companies acquired the site – a former printing press – and broke ground on the data center in 2014.

In September 2022, Bulk announced it had successfully added 1.5MW of whitespace to the OS-IX facility, in its first upgrade since the acquisition. The company had also completed the installation of an on-site substation at its N01 campus and added 10MW of IT capacity.

Since then, Bulk has broken ground on a new data center at the N01 campus in Kristiansand. The building, which began construction earlier this year, will offer 42MW of IT space in addition to the existing 12MW data center facility. The N01 campus is reported to have the potential to grow beyond 1000MW.

Bulk also has a site in Esbjerg, Denmark.
