Grid losses are an indicator for the efficiency of energy supply grids and thereby for the preservation of resources during energy transportation. In the 2019/2020 fiscal year, the losses in the electricity grid amounted to 2.6% or 203 GWh (previous year 2.5%/209 GWh). The losses in the gas grid caused by venting for repairs and maintenance works amounted to 26,533 m3 in the 2019/2020 fiscal year (previous year: 26,606 m3). The natural gas grid losses correspond to 3,395 t of CO2 (previous year: 3,325 t of CO2).

The use of low-loss, high-efficiency transformers in grid renovation as well as energy-efficient control, regulation and transportation technology alongside with the replacement of low- and medium-voltage overhead lines by underground cables contribute to the further reduction of grid losses.
