Climate Change has a high influence on the energy production and the earning of hydro power plants. On basis of the existing evaluations there will be a minor production of hydro power in Germany. In the near future the production will decrease about 1 to 4 % and in the further future about 15 %. Computer simulations for selected waterpower plants at the rivers Rhine, Lech and Main demonstrate that their earning responses sensitively to variabilities of water supply. According to the circumstances the variability balances from +9 % to-9 %.To counterbalance possible minor productions - of hydro power it is recommended to use the existent potential to optimize the plants - and to improve operation and maintenance.

Germany has set a goal for the year 2030 to cover 45 % of its electric power consumption through renewable energies. Currently about 14% of electricity are provided by renewable energy sources, 25 % of which come from hydro power. As a basis for a German development strategy, the Federal Ministry of Environment, Nature Conservation and Nuclear Safety (BMU) has commissioned further research to determine the additionally usable potential of hydropower throughout Germany, using the consistent method of line potential calculation.

The Ministry of Environment of the federal state Northrhine-Westfalia coordinates the implementation of the EU floods directive in the state's different river basins. To ensure a similar quality of the plans as well as similar participation standards the Ministry has started a coordination and quality management process in 2010. Within this process guidelines and formats are being developed for the regional planning activities. It includes the coordination and the data management for flood risk maps and the planning processes for the Flood Risk Management Plans. The standards and guidance documents are presented here by the contracted consultancies. Source

The Federal Ministry of the Environment has commissioned a research project to determine the hydro power potential of Germany on the basis of an theoretical line potential approach. For this purpose current digital data of terrain morphology and flow rates have been processed and analyzed using a geographic information system (GIS). Considering the parameters of head utilization rate and machine efficiency, the line potential was further broken down to a technical hydro power potential. Results of this study show that 60 % of the large water courses' theoretical hydro potential can be utilized. Of the small and mid-size water bodies about 20 % of the line potential can realistically be utilized. Considering the current use of hydro power, the subtraction of the used potential and the unused technical potential results in a supplementary hydro power potential which is subject to further restrictions such as competing utilizations and legal requirements.
