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).
Our key tasks
Innovation
TenneT presents Hub and Spoke concept for large scale wind energy on the North Sea.
Read moreOur grid
TenneT manages the high-voltage grid in the Netherlands and large parts of Germany. TenneT transmits electricity at 110,000 volts (110 kV) and higher. With around 24,500 kilometres of high-voltage lines, we cross borders and connect countries.
Offshore Outlook 2050
Already by 2030, the originally planned capacity of 15 gigawatts of offshore wind energy will increase to 20 GW.
To Offshore Outlook 2050Electricity market
The energy sector is developing rapidly. The process of European market integration began some years ago. Its purpose is to create a single European market that enables market parties to trade gas and electricity across national borders easily and efficiently.
Transparency data
We provide transparency data on our operations on our Dutch and German transparency page and on ENTSO-E.
To transparency pagesE-Insights
Our vision is to be one of the most transparent Transmission System Operators (TSO) in Europe and thereby creating value for society. In this Energy Insights section we present selected energy related topics and show data, information and valuable insights.
Company
TenneT is a leading European electricity transmission system operator (TSO), with activities in the Netherlands and in Germany. We strive to ensure a reliable and uninterrupted supply of electricity in our high-voltage grid for some 42 million people.

Meet usMobile sensoring
Can data from vehicle sensors contribute to the success of the energy transition? Within the scope of a pilot project, TenneT and VW are currently investigating how weather data obtained from VW Group vehicles can be used to improve solar energy forecasts.
Challenges inherent to the energy transition
The increasing proportion of renewable energy in overall electricity production poses major challenges to TenneT and other transmission system operators. This is due to the nature of the process: the production of solar and wind energy is subject to weather-dependent fluctuations. This makes reliable forecasts increasingly important.
Forecasting errors and their costs
Fog, Saharan dust and other weather phenomena: TenneT are currently forced to invest an eight-figure sum every year in order to compensate for imprecise forecasts in the photovoltaic field alone. The larger the discrepancy between the forecast and actual infeed, the more ad-hoc countermeasures are required from the shift engineers in the control room. The more precise the weather data, the lower the costs incurred by subsequent network interventions.
The pilot project
Can we use sensor data collected from vehicles to project the quantity of actually infed solar energy even more realistically and accurately in terms of the time frame involved? Can these data help us produce even more accurate weather forecasts for the next hours and days? TenneT and Volkswagen are conducting an unprecedented pilot project to determine how data obtained from vehicle sensors can improve solar energy prognoses.
FAQ
For how long has the pilot project with VW been running, and how long will it last?
It was launched in January, 2017, and its pilot phase is projected to continue until the end of the year.
What is being measured?
Brightness, temperature, humidity, rain, air pressure – with the help of sensors, modern vehicles already collect a large amount of the type of weather data that matters to TenneT. Of course, the information collected in this manner primarily serves the purpose of improving safety and comfort for drivers.
How does TenneT use the data?
Within the scope of the pilot project, sensor data from VW Group vehicles (vehicles of the Audi and VW brands) are analysed using big-data methods and imported into feed-in forecasts and projections. This allows TenneT to investigate whether the spatial distribution of the sensors can effect a considerable improvement of the forecast quality.
How does TenneT ensure data protection?
TenneT receives the data in an anonymised, aggregated format. No information concerning individual citizens or vehicles can be derived.
PROMOTioN & MIGRATE
TenneT is participating in two major European research programmes: PROMOTioN and MIGRATE. These programmes were initiated in response to new challenges related to the development of offshore power grids and the increasingly important role of solar and wind energy.

North Sea Wind Power Hub
During 2017, being designated as offshore grid operator in Germany and the Netherlands, TenneT also intensified explorations of the long term offshore grid development vision, based on the Paris Agreement. In June 2016, TenneT presented its long term "Hub & Spoke" vision for large scale far offshore wind energy roll out against cost levels comparable to current small scale near shore locations.
