Project Details for Stadthavet (Category B area)
General Information Name Stadthavet (Category B area) correct
Other names Offshore wind - study area correct
Country name Norway correct
Region Sogn og Fjordane correct
Comments NVE has divided the considered zones into three categories-

Category A: Wind power development within the zone

is technically and economically feasible, and will have

relatively few negative impacts. Grid connection is possible

before 2025.

Category B: Wind power development within the zone will

have challenges related to either technical aspects or conflict of interests/negative impacts. The challenges might

be resolved in the future through technology development,

grid measures and/or mitigation measures. NVE considers

that zones in this category can be opened when technology

matures, or when existing use of the areas changes.

Category C: Wind power development within the zone represents greater challenges than in the other two categories.

Conflicts of interest in the areas are not easily resolved.

Foreseen negative impacts are still considered acceptable. Zones in this category should not be opened at the

expense of zones in the two other categories.

Development status Development Zone correct
Comments on the status After a strategic impact assessment this is one of 8 areas that would be considered only if all of the conditions allowed.

According to the ocean act of 01/07/2010 the establishment of renewable energy production at sea can in principle take place only after the state has opened the specified geographical areas for applications for licenses. This is one area being investigated for suitability.

Export Cables
Please note that export cables connect the offshore transformer (substation) to either; shore or an offshore HVAC-HVDC converter station for onward transmission via HVDC cabling. Please see the converters page for planned converter stations and transmission cables.

The export cable length does not generally include the onshore component. The exception is when the onshore substation is close to shore.
