Research fields

The Fraunhofer IEE in Kassel researches for the national and international transformation of energy systems.



Business units

As an applied research institute, we research and develop solutions for the transformation of energy systems and offer a rich portfolio of services, know-how and products.


Joint research under one roof

The time has finally come: it is May 2022 and our employees have moved into the new building. The offices are gradually being occupied and the move is for the most part completed. Some of the laboratories and their infrastructure have been in operation for a while and have already passed the practical test.

Our new Address

Joseph-Beuys-Straße 8
34117 Kassel

Data4Grid Challenge: Fraunhofer IEE Consumption Forecasts receive an Award

Dominik Jost, Jonas Koch and Dominik Beinert, scientists at the Fraunhofer Institute for Energy Economics and Energy System Technology IEE, have won the Data4Grid Challenge "AI-supported consumption forecasts based on smart meter data". The competition was organized by the German Energy Agency (dena) and umlaut. The results and award ceremony presentation took place at the Future Energy Lab in Berlin on May 4, 2022.



Management of reactive power in distribution grids: Fraunhofer IEE and partners develop new method

With the decentralisation of power generation, distribution grid operators are increasingly required to mobilise reactive power depending on the situation. In the research project "RPC2", Fraunhofer IEE, together with partners from grid operation and the University of Kassel, has now developed procedures with which grid operators can control generation and other plants in the medium and high-voltage level in such a way that they provide reactive power according to demand.



New Power Electronics for a Brighter Future

New technologies for use in next-generation photovoltaic inverters are in development and undergoing practical testing as part of the GaN-HighPower project.



Head change at Fraunhofer IEE: Mackensen succeeds Rohrig

As of February 15, 2022, the management of the Fraunhofer Institute for Energy Economics and Energy System Technology IEE in Kassel will be taken over by Dr. Reinhard Mackensen, who the Fraunhofer Executive Board has commissioned to run the business until the ongoing appointment procedures at the TU Darmstadt and the University of Kassel for a new dual leadership in the institute's management have been completed.
