- Description :
- Pursuant to §17d EnWG, transmission system operators must construct and operate offshore connections as defined in the German Grid Development Plan (NEP) and the Site Development Plan (FEP) according to §5 WindSeeG.
In this context, 50Hertz is responsible for the offshore grid connection for thetwo offshore sites N-12.4 and N-12.5. The planned total generation capacity of the two offshore sites N-12.4 and N-12.5 amounts to 2 GW. Therefore, 50Hertz introduced the project NSC2 which will connect the two wind farm sites to the onshore grid. The grid connection system will be realised with 525kV DC technology and a transmission capacity of 2 GW with a required Readiness-for-Trial-Operation in 03/2034.
NSC2 comprises the projects LanWin6 and DC32 and is integrated into the NordHub. The scope of all three projects is briefly described in the following.
The LanWin6 project (defined as projectNOR-12-3 in the NEP) aims at the connection of the two offshore wind farm sites N-12.4 and N-12.5 via an offshore converter station and a DC sea and land cable connection to a Multiterminal Hub. The offshore wind farms will be connected via a 132 kV (AC) direct connection to the offshore converterstation.
The Multiterminal Hub, to which LanWin6 is connected to, is planned in the Poeschendorf search area and is called NordHub. It will be designed as a 4-terminal hub, i.e. it will integrate the two converters of the NSC2 project and the two converters of the LanWin7 project (developed byGe... - Documents :
