The vertical grid load is the sum, positive or negative, of all power transferred from the transmission grid to distribution grids and final consumers through directly connected transformers and power lines.The total load (also called grid area load) is the sum of actual generation output in the 50Hertz grid area and the actual performed power exchange across the grid area borders.The term grid load describes the actual physical load on individual power lines or grid elements.
The vertical grid load shows the power flows in the extra high-voltage grid (>220 kV). These are calculated as the sum of all power transfers from the extra high-voltage level of the transmission grid to the distribution grids with lower voltage levels (high, medium and low voltage) as well as to larger, directly connected final consumers. It is therefore the actual amount of electricity to be supplied directly to the transmission grid (by large power plants) at a given point in time. In contrast to the grid area load, the feed-in from the medium and low voltage level with negative values, e.g. from wind turbines or photovoltaic installations, is included in the total vertical grid load and reduces its capacity value. In other words: the more electricity is fed into the transmission grid from the medium and low voltage grids, the less electricity has to be made available by the transmission grid ‘itself’.
The data on this page are of particular interest for market players, but also for associations, politicians or universities, which is why we make them available to the public here. Data from our archives are also available further below.
The 15-minute average of the vertical grid load is published as a capacity figure in megawatts (MW) for the respective quarter of an hour. Periods for which no, or implausible, values are available carry the entry "not available" (n/a).
Past figures in table form as well as maximum and minimum values of vertical grid load are available for download in CSV format in the following files:
