Green Mountain is a Norwegian wholesale colocation provider that designs, builds, and operates data centers, renting rack, cage, and suite space to enterprise, cloud, HPC, and hyperscale customers rather than selling cloud services of its own. Founded in 2009 and majority-owned by Israel’s Azrieli Group since 2021, the company operates facilities in Norway (Rennesøy near Stavanger, Rjukan in Telemark, Enebakk near Oslo, and a large Hamar campus built as a single-tenant site for TikTok) plus a London-area site in Romford acquired from Infinity SDC in 2022, and is developing a further campus near Frankfurt, Germany. Its signature differentiator is its flagship DC1-Stavanger facility, built inside a former NATO ammunition mountain bunker, alongside a broader strategy of powering all sites with 100% Norwegian/Nordic renewable hydropower and free/fjord cooling to achieve very low PUE and cost. The Hamar campus, built to host TikTok’s Project Clover European user data under a deal covering up to 150MW, is described by the company as set to become Europe’s largest data center run entirely on renewable energy.
