The global transition to renewable energy is increasingly dependent on sophisticated digital infrastructure that can support complex, large-scale energy generation and transmission systems. 

In the North Sea, a pioneering project is demonstrating how advanced telecommunications technology can unlock the potential of offshore wind energy, bridging the gap between digital innovation and sustainable power generation.

Telecommunications equipment manufacturer Nokia has been selected to provide critical communication infrastructure for TenneT's expansive offshore wind energy project in the Dutch North Sea. 

The project represents a significant milestone in renewable energy infrastructure, with eight 2GW platforms set to transform energy transmission capabilities.

Offshore energy expansion

Wind power has very quickly emerged as a promising renewable energy technology, playing a crucial role in the global transition away from fossil fuel dependence.

TenneT's ambitious project aims to deliver substantial renewable energy volumes from offshore wind farms to onshore grids, supporting broader climate neutrality targets. The organisation has engaged three distinct consortia to execute this complex infrastructure project, including the Petrofac and Hitachi Energy consortium, the GE Vernova-Seatrium consortium and the GE Vernova-McDermott consortium. 

Each will be responsible for delivering 2GW offshore converter platforms and corresponding onshore grid land stations.

Nokia's project highlights the critical role of digital infrastructure in modern renewable energy systems. The leading telco company will be instrumental in establishing the communication networks that will enable these offshore platforms to function efficiently and reliably.

The project hinges on Nokia's 1830 PSS Dense Wavelength Division Multiplexing (DWDM) solution, a sophisticated optical networking technology that transmits data via light through glass fibres. 

This technology is designed to enable long-distance, high-bandwidth communication between offshore platforms and onshore telecommunications infrastructure.

"Energy security and climate transition can go hand in hand - if smart, mission critical communication networks can power them," explains Subhagata Mukherjee, Vice President, Global Head of Sustainability at Nokia.

Strategic connectivity

Nokia will deliver advanced amplification and transponder technologies that are specifically designed to withstand challenging offshore conditions. The company will also provide comprehensive design, testing and operational support services to ensure network reliability.

This optical networking solution will create a future-ready and resilient network connecting offshore sites to onshore telecommunications infrastructure. This capability is crucial for monitoring and managing remote platforms, which also enables continuous energy transmission across challenging maritime environments.

Marco Kuijpers, Director of Large Projects Offshore at TenneT, explains: "As we expand our offshore energy infrastructure, connectivity becomes more important than ever. The standardised, mission-critical optical network delivered by Nokia plays a central role in enabling the seamless operation and management of our 2GW platforms, allowing us to operate remotely.

"With partnerships like this, Nokia is helping us towards a more independent energy supply and to advance towards the global goals for tripled renewable energy deployment set during the COP28 climate talks."

The implementation timeline positions Nokia's technology deployment for early 2025, with full operational readiness expected by 2029.

“At Nokia we know that 'there's no green without digital,” says James Watt, Senior Vice President of Optical Networks at Nokia.

“By delivering standardised, high-performance optical networking technology that meets the unique demands of offshore environments, Nokia is supporting TenneT in providing reliable green energy to millions of homes across the Netherlands and Europe.”
