More than 120 on-site and 250 virtual participants convened during the event week

Successful First Hybrid Renewable Energy Grid Integration Week

In September 2021, Energynautics hosted again its annual international conferences on grid integration of renewable energies and electric mobility: the Renewable Energy Grid Integration Week.

On 27 September, the 5th E-Mobility Power System Integration Symposium opened the event week, followed by the 11th Solar & Storage Integration Workshop on 28 September and the concluding 20th Wind Integration Workshop, which took place from 29 to 30 September. For the first time, the events were held in a hybrid format, allowing speakers and participants to attend on-site in Berlin or virtually from around the world. On-site participants were very pleased with the opportunity to finally meet their colleagues again in-person.


Wide-ranging agenda with focus on resilience, grid forming, sector coupling

The three specialist events provided an overview of various topics in the field of grid integration of renewable energies and enable an international exchange of experience between industry and research.

With more than 80 presentations in 20 wind sessions and more than 30 presentations in 8 solar sessions, the workshops offered a broad spectrum of topics ranging from resilience, sector coupling and forecasting to hybrid power systems and micro grids. Grid Forming, a controversial topic in previous years, was again a focus of the Solar & Storage and Wind Integration Workshops this year. More than 15 in-depth presentations were given in the four sessions dedicated to the topic at this year’s workshops.


TSOs and international experts – from 50Hertz to IRENA and NREL

During the Wind Keynote Session, participants gained in-depth insights into developments and strategies for grid integration of renewable energies. In presentations by 50Hertz, the International Energy Agency (IEA) and the International Renewable Energy Agency (IRENA), participants learned more about the challenges and approaches to implementing the energy transition. Prof. Peter Cramton from the University of Cologne and University of Maryland also addressed the topic of resilience in his keynote lecture against the backdrop of the experiences from the Texas blackout earlier this year.

In addition, 50Hertz, TransnetBW and Amprion, together with speakers from the German Bundesnetzagentur and the University of Duisburg-Essen, presented the effects of the exit from coal-fired generation in Germany on transmission adequacy and security of supply.

Further presentations by various transmission system operators such as TenneT, RTE, Amprion, REN, Fingrid, 50Hertz, Elia, TransnetBW, various wind turbine and PV manufacturers as well as universities and research groups rounded off the event agenda, which also included special sessions on the SINTEG project WindNODE or the IEA Wind Task 25, for example.

The role of electromobility on the way to Net Zero

The 5th E-Mobility Power System Integration Symposium focused on charging infrastructure and offered sessions on grid and regulatory aspects, vehicle-to-grid and modelling aspects. In the E-Mobility Keynote Session, speakers from the Belgian transmission system operator Elia, the US Electric Power Research Institute (EPRI), the Volvo Group and the International Energy Agency shed light on various aspects of the global development of electric mobility on the way to “Net Zero”.

In addition to the conferences, Energynautics also hosted two introductory virtual tutorials on Grid Integration of Electric Vehicles and Lessons Learned: Grid Integration of Variable Renewable Energies.


With more than 120 on-site and 250 virtual participants that gathered during the event week, the Renewable Energy Grid Integration Week again proved to be the premier science-to-industry platform with a full focus on RE grid integration.

The Call for Papers for next year’s events will start in February 2022. Find updates on the event websites:
