30 Nov 2020: On 26th August 2020, the OED sent a letter to NVE requesting NVE to undertake an assessment to verify if significant changes have taken place since the 2012 report, in order to consider reclassification from a B Category to an A Category (these categories control priority of opening up areas for development). They also asked NVE to consider alternative demarcations. NVE concludes that there is no basis for the category change, and the area may now be less suitable for development. On 30th November, NVE published a report detailing its decision: NVE does not approve of changing the classification but does recommend investigation into splitting Traenafjorden-Selvaer into two areas. Broadly, it's considerations included: Changes to seabird populations: Since 2012 there has been a decline in seabird populations, and therefore more input from the Environmental Agency is required to identify potential impacts of development in the areas. Shipping Traffic: increase since 2012, expected to continue increasing. Overlap with petroleum activities: Traena Vest extends 1.5 km into an area that in 2019 was opened for petroleum activities, and a decision will be taken on whether drilling will go ahead in March 2022. Clarification on petroleum activity is required before the area could be opened, potentially conflict can be resolved via amending the area boundary. Technological advancements: As the market has evolved since 2012 (e.g. offshore accommodation platforms are not indsustry standard as previously predicted), new market assumptions affect profitability assessments but do not make a significant difference to ranking of areas. Electricity price:NVE highlights that Traena Vest and Traenafjorden-Selvaer are in electricity area NO4, which has the lowest electricity prices. Stattnet provides input on grid availability: line upgrades have been made with future planned, but installed capacity in Norway and northern Sweden has also increased since 2012. Summary Traena Vest: The Norwegian Coastal Administration considers that high ship traffic means the area is unsuitable, but risks could be mitigated by amending the area boundary. It is an active fishing area, and also overlaps with petroleum licence 1014. Further research is also required into seabird migration.
