We want to provide our customers with a reliable and affordable supply of electricity and gas at all times. Our programme of continuous investment in maintaining, expanding and developing our distribution grids and generating plants is directed towards this objective. Our generation mix of renewable-based and fossil-fired power stations helps us to minimise procurement risks. We diversify the procurement of our fuels as far as possible.
The reliable supply of electricity and gas to our customers depends firstly on generation and provision of electricity and gas, and secondly on transmission and distribution. The big challenges currently confronting the electricity industry are in the areas of grids for transmission and distribution. They have resulted from the energy transition and the expansion of renewable energies. Whereas feed-in of electricity from renewable energies into the electricity grid takes precedence over other forms of generation, the supply of electricity undergoes significant fluctuation as a result of the prevailing weather conditions. However, since we are a grid operator, we have to guarantee a secure supply of electricity even under adverse weather conditions.
We operate electricity distribution grids in Germany, Poland and Hungary with a total length of 405,347 km, and a grid of 343,750 km makes us the biggest operator of distribution grids in Germany. We therefore play a major role in providing a secure supply of electricity. We also operate 37,050 km of gas distribution grids in Germany and 49,500 km in the Czech Republic. We operate a gas transmission grid that is 3,600 km in length in the Czech Republic, which is currently up for sale.
