7Overview
The municipality shows promising development in hydrogen and datacenter sectors with 51 MW of active queue capacity, led by Nordic Electrofuel's hydrogen projects. However, Yara's withdrawal of a massive 600 MW industrial connection highlights grid capacity challenges. Substantial grid infrastructure upgrades are underway, including Statnett's new 420 kV transmission line.
Recent Activity
Strong momentum in March 2026 with Nordic Electrofuel and POLARDC advancing from queue to reserved status for hydrogen and datacenter projects totaling 25 MW, indicating improved grid capacity allocation.
Key Substations
Outlook
Positive prospects for hydrogen sector development with Nordic Electrofuel leading the way, while major grid infrastructure upgrades should improve capacity. However, the Yara withdrawal suggests potential grid constraints for large industrial users that may limit massive consumption projects.
