Annual peak load and load curve

The load curve in the form of the grid feed-in is the sum total of all feed of grid transfer points, power plants, and distribution networks into the maximum voltage network (network area 1) in the control area of TenneT TSO GmbH.

Notification

Due to necessary maintenance work on one of our IT systems, there will probably be delays in the publication of the load history data shown below between 11.05.2019 and 12.05.2019. We apologize for any inconvenience.

The load curve in the form of the grid feed-in is the sum total of all feeds of grid transfer points, power plants, and distribution networks into the maximum voltage network (network area 1) in the control area of TenneT TSO GmbH. 

To guarantee that everything is as up-to-date as possible, the load curves are published on the following working day. In so doing, the data is made available to the best of TenneT's ability. TenneT TSO GmbH accepts no liability with respect to this data. Claims cannot be asserted against this data, if it is not possible to determine or supply the data for technical reasons.

TenneT reserves the right to effect retroactive changes to the data if this is necessary for correction purposes.

Provisional annual peak load

The annual peak load corresponds to the maximum value of the respective load curve in a calendar year. You can see the annual peak load by selecting "this year" in the date range picker. The minimum and maximum values are marked with an arrow in the curve chart.

Annual peak loads of the years 2004-2018

The annual peak load in the form of the grid feed-in is the maximum total of all feeds of grid transfer points, power plants, and distribution networks into the transmission network in the control area of TenneT at one point in time in one calendar year.

The information for the years up to 2008 was taken over from our legal predecessor, E.ON Netz GmbH.
