Grid losses are an indicator of the efficiency of energy supply networks and, in turn, of resource conservation levels in energy distribution. In the 2018/2019 fiscal year, the losses in the electricity grid amounted to 2.5%, i.e. 209 GWh (previous year: 2.5%/215 GWh). The losses in the natural gas grid from discharge during repair and maintenance tasks accounted for 26,606 Nm3 in the 2018/2019 fiscal year (previous year: 53,543 Nm3). Line losses on the natural gas grid are equivalent to 3,325 t CO2.

The Group is taking steps to reduce these losses by exchanging old transformers with new ones and continually replacing medium and low-voltage overhead lines – in particular, with underground cables, which are much easier to install at these voltage levels than on the high-voltage grid. Energie AG also works to ensure low energy consumption for metering and secondary technical components (measurement, control, management and data transfer).
