Energy meteorology systems

Forecasts for a reliable energy system

Digitalisation, automation and the usage of intelligent algorithms are becoming increasingly important factors for success in the energy industry.

This is particularly true for the integration of renewable energies (RE), for which precise and reliable forecasts of the expected energy production and consumption are indispensable. This can increase efficiency, minimise risks, and save costs.

Our real-time power estimates and forecasts are the centrepiece of innovative solutions for reliable grid operation and planning with weather-dependent energy sources.

Get to know our portfolio and let us support you to achieve your goals. As a reliable and innovative partner, we are always prepared to support you.

Our offers

  • Forecasts of the expected renewable energies (RE) generation in the next few minutes up to days.
  • Estimates of the energy generation from spatially distributed renewable energy plants.
  • Forecasts of the expected electricity, heating/cooling, and water consumption by households, enterprises, and utility networks.
  • Dynamic methods for the determination and prediction of the possible ampacity of overhead conductors,  considering external weather conditions.
  • Forecasts of the expected power flows within (horizontal) and between (vertical) the different voltage levels in the grid.
  • Consulting and project planning based on state-of-the-art methods from science and research on the characterization and mapping of energy-meteorology relationships.

White Paper GLDPM


Cross-country power flow calculations are performed to determine maximum transmission capacities between European market areas. To make these even more reliable and to map the operations of the transmission grid level (150 kV to 380 kV, in Western Europe mainly 220 kV and 380 kV) in more detail, the Generation and Load Data Provision Methodology (GLDPM) has been developed to provide the grid data required for power flow calculations. Its implementation should be completed in 2018.


  • Overview of the generation and load data provision methodology
  • Provision of data for network modeling from the high-voltage level
  • Forecasts for network calculation
  • Data transmission process
  • Possibilities for further use
  • Summary and outlook

DIN EN ISO/IEC 27001 Certification

For Fraunhofer IEE, the secure and efficient handling of critical data and secure information systems is important. That is why we have had an information security management system (ISMS) certified for various business areas. The focus is on efficient risk management and continuous improvement of information security, for example by being prepared for possible cyber attacks and IT emergencies. The functionality of our ISMS is regularly checked in external audits by independent third parties.
