Fraunhofer IEE

What Fraunhofer IEE does

Fraunhofer IEE is a German applied research institute headquartered in Kassel and a constituent entity of the Fraunhofer-Gesellschaft, employing approximately 278 staff across research and engineering functions. It operates six interconnected research domains covering the energy system transformation: energy informatics, energy meteorology, energy economics and system design, grid planning and grid operation, power electronics, and thermal energy. The institute develops technologies and methods that support grid operators, municipalities, energy providers, project developers, and industrial partners in integrating renewable generation, electrifying transport and heat, and decarbonizing industrial energy use.

The institute's product portfolio spans open-source software (pandapower for grid simulation, EnergyFaultDetector for AI-based anomaly detection in wind and PV assets), proprietary platforms (EnergyConnect virtual power plant, MetFox forecasting, Gridfox, BaSiS), and hardware-driven systems (Power-HIL hardware-in-the-loop, StEnSea underwater pumped-storage). It coordinates DERlab, the European pre-standardization network for distributed energy resources laboratories, and collaborates with other Fraunhofer institutes, universities, and international bodies including IRENA and Strathmore University.

Revenue is generated through a mix of German federal and state research funding, EU and transnational program grants, and industry-funded research contracts; pricing is project-based rather than transactional. Recent activity includes the EUR 4.2M 'H2Global meets Africa' Kenya PtX-Atlas project, the OASES consortium with IRENA, bidirectional EV-truck charging work with MAN Truck & Bus, dynamic energy management with T-Systems under IPCEI-CIS, and ISO/IEC 27001:2022 certification formalized in September 2025.

Core offering

Fraunhofer IEE is an applied research institute conducting contract research and developing proprietary software tools, hardware test systems, and consulting services for the transformation of energy supply systems. Its core offerings include energy forecasting systems, grid simulation and planning tools (e.g., pandapower, EnergyConnect virtual power plant), hardware-in-the-loop testing platforms, and digital energy management solutions delivered to utilities, grid operators, municipalities, and industrial partners.

Product overview

Fraunhofer IEE is an applied research institute (not a commercial software company) offering a portfolio of energy system technologies and tools. The core offerings include forecasting systems (MetFox for meteorological data, wind/solar power forecasting, Gridfox for power flow forecasts), grid planning and operation tools (pandapower for power system simulation, beeDIP for data integration, CIM CGMES Konverter for interoperability), and digital energy management platforms (EnergyConnect virtual power plant). Supporting products include Hardware-in-the-Loop testing systems (Power-HIL, BaSiS battery simulation), urban planning tools (EQ-City, UrbanTwin digital twin), and specialized technologies like StEnSea marine storage. Recent additions include EnergyFaultDetector (open-source fault detection) and various PtX/hydrogen analysis tools. The institute operates test centers and laboratories rather than selling commercial products, offering research services, consulting, and technology transfer to industry partners.
