4C Offshore Empowering Intelligence
31 Mar 2023: The BMWK is consulting the layout of sub-areas of the other energy production area SEN-1 (Q4 2022 Market Overview). Consultation closed on 31st March 2031. In the latest FEP SEN-1 was defined as a larger area (102 km²) and is now being considered for tendering as two to three smaller subareas. Developer and industry responses lobby for smaller staggered tenders to allow increased competition, risk spreading, testing multiple technologies, and technology scaling. It was also consulted on whether to auction all subareas simultaneously or stagger tenders. Developers consider consectutive calls for proposals to be suitable to allow for learning and scaling of technology. Responses were submitted by Equinor, RWE, Vattenfall, SGRE, BDEW, EnBW, BWO, WAB, and CIP. The Ordinance on Auctioning Sites for Alternative Energy Generation in the Exclusive Economic Zone (SoEnergieV) sets the auction rules and entered into force on 1st October 2021. A tender was originally expected mid-2022.
