Hydropower Forecast
Hydrological forecast of the energy production for catchment areas
EWC and VISTA’s Hydropower Forecast supplies daily forecasts of runoff and related energy production volumes for hydropower plants ≥ 5 MW for up to 10 days. In addition, water temperatures for each river kilometre are available.
Your benefits from the Hydropower Forecast
- Runoff calculations at hourly intervals; daily forecasts
- All hydro-meteorological data for precipitation and water levels, evaporation and percolation, groundwater retention and runoff
- Highly accurate predictions of water temperature enable excessive cooling water temperatures to be estimated
EWC: Meteorological database
EWC supplies the relevant weather measurement and forecasting data required for VISTA’s „HydroSense” forecast service. This data includes precipitation, air pressure, temperature, humidity, global radiation and sunshine duration data, in addition to historical data for the analysis of model results based on periods in the past.
- Meteorological data are exclusively from official national weather offices operating to WMO standards (World Meteorological Organization)
- Germany-wide hourly readings from over 1,000 weather stations of Deutscher Wetterdienst
- Europe-wide readings from over 2,500 weather stations at 1-6-hourly intervals
- Data accuracy is enhanced by the application of an interpolation model
- Runoff calculations can be aggregated over various periods, e.g. as daily, monthly or annual figures
Calculation of water temperature
Daily forecast of the energy production of over 100 hydropower plants in the Upper Danube catchment area
VISTA: Data processing with the full-scale water management model PROMET
VISTA’s „HydroSense” forecast system is based on PROMET (Process of Radiation Mass and Energy Transfer), a physics-based, uncalibrated satellite-supported model that simulates the spatial distribution of all terrestrial and atmospheric elements of the water cycle. The realistic raster-based system models open-channel hydraulics, lake retention and reservoir management. Continuous monitoring of the liquid water/snow equivalent – the volume of water stored in the snow – enables the volume of energy stored in the snow cover to be estimated. The system delivers data on groundwater, snow and ice water equivalents, groundwater balance and evaporation (taking vegetation into consideration).
