2019Commercial Operations Full Power
BorWin3 grid connection system commissioned and operational.
12 Aug 2019Cable Installation Complete
TenneT's 155 kV HVAC export cable connecting EnBW Hohe See wind farm to BorWin3 converter platform completed. ZTT supplied cable, SeaRenergy/EDS provided installation support.
12 Aug 2019Onss Commissioned
By 12 August 2019, TenneT had commissioned the 900MW BorWin3 offshore grid connection linking the BorWin gamma offshore converter platform to the onshore converter station and substation at Emden/Ost, enabling power from connected offshore wind farms to be fed into the German extra-high voltage grid over the 160km HVDC link.
Sept 2018Construction Other
In September 2018, the topside of the BorWin gamma offshore HVDC converter platform for the 900MW BorWin3 grid connection was transported by heavy lift vessel from Dubai to the installation site in the North Sea, around 130km off Borkum, and installed on its jacket foundation as part of Petrofac’s EPC scope for TenneT.
12 Jul 2017Procurement Other
SeaRenergy was contracted by ZTT to provide QHSE management and support for the HVAC export cable connection between the BorWin gamma platform of the BorWin3 grid connection and the EnBW Hohe See offshore wind farm, covering cable load-out, transport, installation, commissioning and testing, with work already commenced and completion scheduled for the second quarter of 2019.
Mar 2017Cable Supplier Selected
Chinese power cable manufacturer ZTT was awarded a contract in March 2017 as general contractor for TenneT to supply and construct a 155 kV HVAC grid connection between the EnBW Hohe See offshore wind farm and the 900 MW BorWin3 DC grid connection system, delivering the connection as a turnkey solution including shunt reactors, a GIS terminal and land conversion joints in a EUR 25 million project executed with Van Oord and Siemens.
2015Other Permit Awarded
In 2015, the BorWin3 offshore DC grid connection owned by TenneT was licensed, with TenneT DE recorded as the grid transmission owner for the 900 MW project. This licensing milestone established the regulatory basis for TenneT’s ownership and operation of the BorWin3 transmission asset in the German North Sea.
12 Mar 2015Manufacturing Update
By March 2015 Prysmian Group reported that it was already implementing the HVDC cable systems for Germany’s DolWin3 and BorWin3 offshore grid connection projects, highlighting its ongoing execution of high-voltage submarine and land cable system supply and installation for these links.
15 Apr 2014Converter Supplier Selected
TenneT awarded the BorWin3 900 MW HVDC offshore grid connection EPCI contract to the Petrofac / Siemens consortium. Siemens responsible for HVDC converter technology, Petrofac for platform EPCI.
