European transmission operator TenneT has announced its selection of Nokia to deliver cutting-edge optical networking technology for eight new 2GW offshore converter platforms in the Dutch North Sea. This strategic partnership aims to enhance connectivity between offshore platforms and TenneT’s onshore telecommunications infrastructure.
Nokia’s Optical Network Solution for Offshore Platforms
Deployment of Nokia’s 1830 PSS DWDM Technology
Nokia will implement its 1830 PSS dense wavelength division multiplexing (DWDM) optical network to interconnect offshore sites with onshore systems. This solution will enable real-time monitoring and management of remote platforms, ensuring reliable energy transmission across TenneT’s grid.
Advanced Amplification Systems for Long-Distance Transmission
To support the demanding offshore environment, Nokia will provide advanced amplification and transponder technologies. These systems allow single-span, unrepeated transmissions over distances of up to 400 kilometers (248.5 miles). Nokia’s extended-reach amplification systems are specifically designed to maintain dependable optical transport in challenging marine conditions.
Comprehensive Support Services
Design and Operational Support
In addition to the hardware, Nokia will offer design, testing, and operational support services. These services are intended to ensure the network adheres to TenneT’s rigorous standards during construction and long-term operation.
Early Implementation Timeline
Implementation of the networking solution is scheduled to begin in early 2025, aligning with the initial construction phase of the offshore platforms. This timeline allows for early integration and thorough testing of communication systems, supporting TenneT’s objective to achieve full operational readiness of the first platform by 2029.
Strategic Partnerships and Future Plans
Offshore Converter Platforms
TenneT has engaged three consortia for the construction of the 2GW offshore converter platforms and onshore grid land stations:
- Petrofac and Hitachi Energy consortium
- GE Vernova-Seatrium consortium
- GE Vernova-McDermott consortium
These consortia were selected during TenneT’s first large-scale European Union tender in June.
Upcoming HVDC Cable Tender
In addition to the platform development, TenneT plans to launch a large-scale high-voltage direct current (HVDC) cable tender. This initiative will cover at least ten connection systems to transmit wind energy from offshore sites in Germany and the Netherlands to the mainland.
Current Connection Capacity and Expansion Goals
TenneT currently operates with a connection capacity of 2.8GW in the Dutch North Sea. The deployment of these new platforms and supporting infrastructure will significantly boost TenneT’s capacity to meet Europe’s growing renewable energy demands.
