Hydro Power forecasting



HydroFor™ is a software solution for operational hydropower forecasting. HydroFor™ forecasts in-flows to hydropower plants which can then be used to forecast or optimize the power production from run-off-the-river or reservoir based hydropower plants.


Why do you need HydroFor™?

Plan and manage

Hydropower forecasting is a necessity in order to plan and operate the power system efficiently. This applies to both commercial players in liberalized power markets and system operators. Accurate hydropower forecasting is needed by asset owners and electricity traders in order to optimize and trade power production efficiently. By increasing forecast accuracy, asset owners and traders can optimize the operation of hydro plants with reservoirs and reduce costs of imbalance fees and penalties from run-of-the-river hydro plants.

Accurate forecasting

Transmission system operators need accurate hydropower forecasts to maintain system stability and keep the system operating costs at a minimum.

The highly accurate hydropower forecasts delivered by HydroFor™ can help asset owners, traders and system operators around the world to manage and optimize their portfolio every day.

Key benefits

  • Market leading hydro power forecast accuracy
  • Highly flexible and configurable to almost any conditions
  • Reduces costs for traders, asset owners, and TSOs
  • Low maintenance system with minimal interference for the customer
  • Tailor-made modules handling complex requirements for various types of hydro plants

How does HydroFor™ work

HydroFor™ is a self-learning and self-calibrating software system based on a combination of physical models and advanced machine learning. The physical model separates forecasted inflow into a direct component from immediate precipitation into the reservoir and a delayed component represented by precipitation aggregated over the catchment. The model is trained using forecasted inflow (precipitation and evaporation) and observed inflow derived from reservoir water level, turbine flow and overflow.  This combines the best of artificial intelligence with hydro power domain knowledge in order to produce the most accurate hydro power forecasts available.

Forecasts are produced every time the system receives new data, which can be updated weather forecasts or new measurement data. HydroFor™ can run in either an online mode (continuously receive real-time measurement data) or in an offline mode where historical data is retrieved monthly, or any other time interval.

The system can use one or more weather forecast providers as input and automatically detect the optimal prioritization of the different weather forecasts for each hydro plant and for different forecast horizons.

The self-learning and self-calibrating algorithms will continuously learn about the catchment area and the hydro plant characteristics. The algorithms will adapt to changing conditions, seasonal variations, and as the turbine ages, such that forecasts stay accurate over time without the need for manual configuration.

HydroFor™ can deliver power forecasts in almost any file format and can be integrated directly into the operational IT-platform of the client, such that data is retrieved and delivered seamlessly to and from relevant systems.

HydroFor™ is available as a software package installed locally on the client’s servers, or as a service hosted on servers operated and maintained by ENFOR™. HydroFor™ is supplied with various support, maintenance and license packages, which can be customized to client specifications to provide a cost/performance ratio which fits the needs of the individual client.
