Prysmian scores €200 million cable contract for Sofia
Prysmian Group is set to provide a turn-key high voltage submarine and
land export cable connection for RWE Renewable’s 1.4 GW Sofia
offshore wind farm in the central North Sea.
A preferred bidder agreement, worth over €200 million, was signed today
(17 November 2020) between RWE Renewables and Prysmian Group for the design,
supply, offshore route preparation, installation, commissioning and protection
of the 320 kilovolt (kV) high voltage direct current (HVDC) cable system
that will carry power from Sofia’s offshore converter station 227 kilometres
to the project’s onshore converter station in Teesside.
The agreement includes symmetrical monopole HVDC submarine and land export
cables, the latter using new eco-sustainable cable technology. It also
means Sofia will be the first offshore wind project to use the 170-metre-long
Leonardo da Vinci, which will be one of the most advanced cable-laying
vessels in the world when delivered in 2021.
Sven Utermöhlen, Chief Operating Officer Wind Offshore Global of RWE Renewables,
said: “We are delighted to announce the selection of world leading
cable supplier Prysmian as our preferred bidder for this package and confirm
the project will be the first to use their latest HVDC cable technology
and the cutting-edge Leonardo da Vinci. Today’s signing is another tangible
step for RWE Renewables’ Sofia as the project progresses towards a final
investment decision in early 2021 and is set to make a major contribution
to the UK’s climate goals.”
Hakan Ozmen, EVP Projects BU, Prysmian, said: “We are honoured to support
RWE Renewables in this important offshore wind project, providing our state-of-the-art
cable technology to support UK’s sustainable energy system towards the
country’s net-zero emission target. The development of grid infrastructures
for the transmission and distribution of electric power from renewable
sources is strategically important, and positions Prysmian as the leading
company for the energy transition.”
The contract involves more than 440 kilometres of ±320kV submarine export
cables with XLPE insulation, and 15 kilometres of ±320kV land cables with
P-Laser insulation, plus communications cables.
Detlev Waimann, CCO Projects BU, Prysmian Group added: “P-Laser is
the first 100 percent recyclable, eco-sustainable, high-performance cable
technology based on the use of a patented thermoplastic material, High
Performance Thermoplastic Elastomer (HPTE) and on a zero-emission process
that reduces CO2 emissions by 40 percent. This project sets an important
technological milestone in the offshore wind industry, being the first
± 320kV DC offshore wind farm using P-Laser cable technology onshore.”
Onshore construction will get underway at Sofia's
converter station site in Teesside early next year, with offshore construction
anticipated to start in 2023. The installation and commissioning of the
HVDC export cable is due to be take place in 2024.
This HVDC export cable news follows the announcements that a consortium
of GE’s Grid Solutions and Sembcorp Marine will supply Sofia’s HVDC transmission
system and Siemens Gamesa Renewable Energy will supply the wind farm with
its SG 14-222 DD offshore wind turbines.
wind farm is 100% owned by RWE, the second biggest player in offshore wind
globally and the UK's second largest generator of electricity. By 2022,
RWE plans to invest €5 billion net in the continued expansion of renewable
energy, and with the UK one of their core markets in Europe.
