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).
TenneT presents Hub and Spoke concept for large scale wind energy on the North Sea.
Read moreTenneT 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 23,000 kilometres of high-voltage lines, we cross borders and connect countries.
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.
We provide transparency data on our operations on our Dutch and German transparency page and on ENTSO-E.
To transparency pagesOur 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.
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 41 million people.
The actual wind energy feed-in (sum of onshore and offshore) describes the total physical wind energy feed-in in the TenneT control area per unit of time. The data are based on an extrapolation of the online measured feed-in values of reference wind farms. The forecasted wind energy feed-in is a combination of several wind energy feed-in forecasts as of 8:00 a.m. for the following day (previous day's forecast).
The generation of wind energy highly depends on current weather conditions. In the course of the energy transition, the generation levels from volatile wind energy are constantly increasing. Accordingly, forecasting actual generation due to the high installed capacity is a particularly important and challenging task.
We are continuously working to reduce the discrepancies between forecasted and actual output. This ensures a reliable power supply and reduces costs, for example for the use of control energy.
The actual wind energy feed-in is shown as a quarter of an hour average for the respective time. For example, 11:15 a.m. references the period from 11:00 a.m. to 11:15 a.m. The diagram shows values from the operational measurement; thus, data updates are possible.
