Inflow forecasting is essential to keep control of your water resources. By managing your resources in an optimal way, you can plan the power production more accurate and maximise revenue from your assets.
Inflow forecasting depends on several elements such as weather forecasts, snow storage, ground conditions and the landscape formation. Powel inflow modelling and forecasting takes all these elements into account, to give insight into the future available resources.
"Despite more advanced and sophisticated hydrological models, the model, in its simplicity, remains one of the fastest and best-suited models used in hydro production planning," says Beate Sæther, product manager at Powel.
Market leader in the Nordic countries
It’s a well proven model for different climate conditions and is a market leader in the Nordic countries.
The Powel inflow model is based on the traditional HBV concept developed in Sweden in the early 1970’s. The model simulates the natural run-off from a catchment and covers the main, hydrological processes by calculating snow- and glacier accumulation and melting, evaporation and inflow delays from soil moisture, ground water and lakes. It uses meteorological observations and forecasts of temperature and precipitation and historical inflow as input.
Powel Inflow has built-in advanced feature for auto-calibration of model set-up to easily adapt to different catchment areas.
Updated frequently with historical measurements
The model catchment is divided into ten elevation zones to provide for more accurate distribution of precipitation as snow or rain. The input data could be connected directly into each elevation zones to utilize more distributed weather information.
The model is updated frequently with historical measurements giving you the best basis for the future inflow predictions based on weather forecasts.
You can order weather data from meteorological institutes or use our Weather Utility tool to download available, free weather data from met.no in Norway.
"One of the great benefits with our inflow model is that you can create inflow forecasts for both short-term and long-term horizons and utilize historical weather data and ensemble forecast scenarios to create probability spread of expected inflow," says Sæther.
Could be used for analysis of spring floods
"During the winter months the state of the snow storage constrains the inflow and it is crucial to have an up to date state of the snow storage in each of the individual catchment before the snow melting period starts," says Sæther.
Powel Inflow could also be used for analysis of spring floods, water supply, the effect of climate changes and profitability of new power plants and cascades.
Powel Inflow is integrated in the Smart Energy portfolio with a powerful time series management system and a user friendly, process-oriented user interface designed for process automation.
