Our key tasks

We are primarily tasked with providing power transmission services, system services and facilitating the energy market. Our core tasks follow from our appointment as grid operator under the Dutch 'Elektriciteitswet' (E-wet) and the German 'Energiewirtschaftsgesetz' (EnWG).

The 2GW Program

One fits all: A new standardised platform, a new certified cable system, a higher transmission capacity – all with the least environmental impact possible. The 2GW Program serves the ground for our next generation offshore grid connection systems.

At a glance

The European energy transition is one of the biggest challenges of our times. Its goal: Making Europe the world’s first climate-neutral continent by 2050. Offshore wind energy from the European powerhouse North Sea will play a crucial role in this. The Netherlands and Germany thus have set ambitious offshore energy goals: by 2030 alone, Germany and the Netherlands want to achieve 20 and 11.6 GW of capacity, respectively. TenneT ensures that this energy reaches land – with the least environmental impact as possible. To increase the pace and be more efficient we set up the 2GW Program, consisting of a unique transnational approach.

Understanding the dimension

TenneT will build at least six offshore grid connections with a transmission capacity of 2 GW each in Germany and the Netherlands until 2030 – three in each country. The accumulated 6 GW per country equate to more than 50 percent of the Dutch expansion target and around one third of the German offshore energy goal for 2030. With this amount of capacity, the 2GW Program exceeds energy infrastructure around the world.

Due to its new innovative design and thus higher transmission capacity, the 2GW Program will reduce the need for resources and the impact on the environment – while providing more energy than prior systems.

The new standard

The 2GW Program features an innovative and holistic approach that fosters harmonisation across all levels – be it with regards to technology, to design, or the way we work and achieve our goals together. By combining our know-how in offshore grid development with a unique transnational approach, we developed a new standard together with the market that has the potential to become a European showcase in offshore grid development. The 2GW Program will save time, resources, and money – and still double the connection capacity by using less cables and platforms in comparison to previous grid connection systems.

One cable system

Together with our partners*, we are developing a new state of the art 525 kV cable system – with the aim to be certified by 2022.

One platform design

The new platform design and a high voltage direct current (HVDC) transmission system allow for increased power transfer – while remaining flexible enough to embrace technological innovation in the future.

One contract model

The 2GW Program’s various projects are governed by a contract based on a FIDIC standard agreement. FIDIC is globally recognised and used throughout the industry. It will make global implementation of the 2GW Program standard much easier for everyone.

The projects

Between 2028 and 2030 TenneT will realise at least six 525 kV High Voltage Direct Current (HVDC) bi-pole connections with a capacity of 2 GW each from designated wind areas in the Dutch and German North Sea. Those projects are part of the 2GW Program.
