Green Mountain has completed its data center campus expansion in Oslo, Norway.

The Nordic data center company has built a new 13.5MW data center as part of its OSL1-Enebakk campus. Announced late last year, it was originally set to open in November.

The multitenant colocation facility will see its first customer move in, in January. It joins two 4MW data centers, designed for single tenants.

Green Mountain said that the 10,000 sq m (107,700 sq ft) three-story building still has some capacity for sale, but that most of it is already reserved. It also has space available in future planned buildings at the campus, which could support 93MW.

"We still experience strong interest from the market. Being able to offer a sustainable data center operated on 100 percent renewable energy is especially attractive for international clients. The site is also ideal both in terms of power availability, connectivity, and proximity to the Norwegian capital," Tor Kristian Gyland, CEO of Green Mountain, said.

"In addition, we designed this data center with flexibility in mind as we wanted to accommodate a broad set of clients’ needs. Customization is the key word."

CTS Nordics was the design & build contractor for the project.
