A short drive from Hamar city, in the Innlandet region, you will find our newest state-of-the-art data center site, OSL-Hamar. The potential campus footprint of up to 1.5 million ft2 can accomodate five buildings, each with a capacity of 30 MW. The initial three buildings are now fully complete and in operation, and the site is home to more than 200 employees.
We are pleased to confirm that TikTok, our customer, has secured a contract for these three buildings, effectively utilizing the entire 90 MW capacity. They also retain the option to expand their capacity to 150 MW meaning our currently planned capacity at the site is fully committed.
The site is built and operated according to Green Mountain's high sustainability standards. This includes the use of renewable power, world-leading energy efficiency, and preparations for heat reuse.
We are actively collaborating with industry and research institutions to explore projects and initiatives that can benefit from the residual heat produced by the data centers.
