EnBW He Dreiht Offshore Wind Farm

28 Mar 2022: Update 25th March 2022: EnBW He Dreiht GmbH has submitted an application to the Federal Maritime and Hydrographic Agency (BSH) to carry out the planning approval procedure for the EnBW He Dreiht offshore wind farm located in the German EEZ. A application documents are available for public consultation from March 28, 2022 up to and including April 27, 2022. The project is located about 110 km west of Helgoland and about 85 km north of Borkum and thus quite centrally in the German Bight. The project covers an area of 62.5 km². Water depths at the site range from 37.7 m to 40.6 mLAT The project design includes: - 64 V236 15MW wind turbines, with a rotor diameter of 236 m, tip height of 263 mLAT and a hub height of approx. 145 mLAT; - The project has a grid connection capacity of 900 MW and therefore has overplanting of 60 MW to compensate for electrical transmission losses or reduced production availability e.g. during maintenance periods; - Monopile foundations embedded to 30 m. The monopile has a total length of approx. 70 m. The maximum diameter of the pile at the foot is 10 m; - The transition piece (TP) has a total length of approx. 32 m. The upper edge of the transition piece, i.e. the base of the tower, is approx. 21 m above LAT. The lower edge of the transition piece is about 11 m below LAT; - 66 kV array cabling, via 13 strings with up to 5 turbines on each string, approximately 110 km; - Array cables will connect directly to the 900 MW BorWin Epsilon converter platform (66/230 kV). The cable structure consists of an aluminum conductor with plastic insulation and have a conductor cross-section of between 240 mm2 and 1000 mm2; - Power is exported via 230 km HVDC cables (NOR-7-1), managed by TenneT; The completion of the OWP "EnBW He Dreiht" is based on the planned completion date of the grid connection in 2025. The construction of the OWP "EnBW He Dreiht" is therefore expected to start in Q1/Q2 2024 with commissioning in 2025. Installation of foundations, scour protection and array cables expected 2024. Installation of the turbines in 2025. The latest possible construction start is 10.09.2025, latest first power is 10.6.2026, and latest commissioning is 2027 under WindSeeG Law. Project lifetime is 25 years. Update 20th October: according to EnBW they plan to submit the application to the BSH "in the course of this year". EnBW plans to submit application Plan Approval & 1st Release to BSH in Q2 2021. Approval by 2023.
