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 greatest challenges of our time. Its goal: to make Europe the first climate-neutral continent by 2050. The Netherlands and Germany have therefore set ambitious targets for offshore expansion: Already by 2030, Germany and the Netherlands want to achieve capacities of 30 and 22.2 gigawatts, respectively. Energy from offshore wind farms in the European powerhouse North Sea will play a decisive role in this. TenneT ensures that this energy reaches the mainland - as environmentally friendly as possible. That is why we have developed the 2GW programme in a unique transnational approach. And thus increase the speed and efficiency of the energy transition.

A new dimension

TenneT will build at least six offshore grid connections with a transmission capacity of two gigawatt each in Germany and the Netherlands by 2030 – three in each country. The accumulated six gigawatt per country equate to 20 per cent of the German and almost 30 per cent of the Dutch offshore energy goals for 2030. 

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.
