3Overview
The municipality hosts critical transmission infrastructure including the Namsos transformer station, which attracts significant energy-intensive industries. While aquaculture companies like Mowi are actively securing grid capacity for expansion, Equinor's withdrawal of a major 171 MW petroleum project highlights potential grid capacity constraints.
Recent Activity
Mowi entered the grid queue in April 2026 with a 10 MW aquaculture project, demonstrating continued industry expansion despite Equinor's earlier withdrawal of a much larger petroleum project.
Key Substations
Outlook
The municipality's strategic position as a transmission hub creates opportunities for energy-intensive industries, particularly in aquaculture and renewable energy. The planned 132 kV upgrade should enhance grid capacity, though competition for connections remains high given the strong industrial interest in the Namsos area.
