A first tender for 1.5 GW is expected by next year at Soerlige Nordsjoe II, some 2,590 square km and bordering the Danish sector of the North Sea, which is suitable for bottom-fixed wind power turbines.
Utsira Nord, an area of 1,000 square km (386 square miles), is located northwest of the oil industry capital Stavanger and is seen as suitable for floating wind power.
Companies and joint ventures that have confirmed their interest are:
Sweden's Vattenfall has joined Seagust, a joint venture between industrial investment firms Arendals Fossekompani (AFK) and Ferd, seeking to bid for both areas.
Shell is partnering with local utilities BKK and Lyse to prepare bids for both Utsira Nord and Soerlige Nordsjoe II.
British oil major BP announced it will join Norway's Statkraft and Aker Offshore Wind to bid for permits in the southern area.
