Hemnes

Overview

Hemnes hosts a remarkable concentration of large-scale energy consumption projects, all converging on Nedre Røssåga KRA/TRA, which is being upgraded by Statnett to 420 kV to meet anticipated future demand. The pipeline is led by Aker Nscale's 1,000 MW datacenter ambitions and Fuella AS's 560 MW green hydrogen reservation, though Fuella recently removed its target connection date and has since withdrawn its queue position, signalling meaningful project risk. Aquaculture and smaller hydrogen producers round out the mix, while two small hydro projects contribute modest production capacity.

Recent Activity

In early July 2026, Fuella AS first removed the target connection date (29 September 2029) for its 560 MW hydrogen reservation at Nedre Røssåga, then fully withdrew the queue position — a significant setback for the municipality's largest hydrogen project. In mid-June 2026, Fishbase Infrastructure's 9 MW aquaculture reservation was reinstated after a period of withdrawn status, indicating continued interest from the aquaculture sector.

Key Substations

Municipality Stance

No explicit municipal stance is evident from the data, but the concentration of large consumption reservations at a single substation and the active grid expansion by Statnett suggest a permissive environment for industrial-scale energy development.

Outlook

Hemnes has a high-potential but high-risk energy development profile. The ongoing 420 kV upgrade of Nedre Røssåga is a critical enabler for the entire project pipeline, and once completed it could attract further large consumers. However, the withdrawal of Fuella's 560 MW hydrogen project removes the anchor tenant for green hydrogen development, and Aker Nscale's 1 GW datacenter ambitions remain speculative at queue stage. Developers should monitor the pace of the substation upgrade, remaining hydrogen interest from GreenH and Hywer, and whether Aker Nscale advances toward reservation status. The high ratio of withdrawn capacity (828 MW) relative to active consumption (1,619 MW) warrants due diligence on grid availability timelines.
