In 2021, Northern Data, formerly known as Northern Bitcoin, bought Hydro66's renewable-powered data center operating in the "Node Pole" region of Northern Sweden. The Hydro66 site consists of six data center halls on a 2.5 hectare plot in the city of Boden. Northern Data plans to expand it to meet demand from its mainly bitcoin customers. The area has an average annual temperature of 1.3°C, and access to 100 percent renewable power from hydroelectric plants.
- In 2023, Northern Data Group separated its operations into three different brands: Taiga Cloud, Ardent Data Centers, and Peak Mining. Northern Data Group will remain the parent company of the three new brands.
- Ardent Data Centers will focus on building data center environments that will use liquid cooling technology and be designed specifically for housing HPC systems.
