Final Report


What exhibitors said about Volta-X

ADS-TEC Energy

„There were really large numbers of visitors at Volta-X as a new event that caught the spirit of the age. As a company operating in the B2B sector, we met the right trade visitors here. We have a very positive feeling and are looking forward to the next Volta-X.“

Dennis Müller SVP, Product Marketing & Communication, ADS-TEC Energy


„GP JOULE showed at Volta-X how the linking of renewable energies with the industry, heat and mobility sectors can work. GP JOULE stands for a constructive combination of energy generation from solar and wind sources and customers' demand for electricity, heat and mobility. The change to alternative energy sources will only function together. It was therefore clear to us right from the beginning that we wanted to be present at the première of Volta-X in Stuttgart. We forged a large number of valuable contacts both with visitors and fellow exhibitors. We were delighted that so many visitors were interested in the talks and panel discussions in which our employees were involved.“

Heinrich Gärtner, co-founder and CTO of GP JOULE

Comments and statements given by the visitors

Stadtwerke Stuttgart GmbH

 „Thanks to the limited number of exhibitors and the special focus on storage technologies, the trade fair offered a great platform for intensive professional interchange on these topics. The accompanying presentation and event programme was, in my opinion, more in-depth and informative in comparison to similar events which I have previously attended. In particular, the centrally located stand of the German Energy Storage Association offered a much appreciated opportunity to exchange views with other exhibitors and visitors. On the whole, from my point of view, a very successful trade fair, which I hope will be repeated in a similar form in two years' time.“

Dr. Joachim Müller, Project Manager Sector Coupling, Public Utilities Stuttgart GmbH

TEAG Thüringer Energie AG

„As a leading energy supplier in the state of Thuringia, TEAG Thüringer Energie AG is particularly interested in holistic and technically innovative solutions for its customers and the operation of its own distribution networks.
The "Volta-X" enabled us to gain a very good insight into the variety of storage solutions currently being offered by competent battery storage manufacturers. We were able to converse on a highly professional level with the spokespersons of the numerous storage manufacturers and service providers attending the trade fair and found the atmosphere at the Stuttgart trade fair to be very pleasant. To put it briefly, we felt very much at ease at the Volta-X 2023. Participation in the numerous workshops offered with presentations led by industry professionals on current topics relating to the utilisation of storage systems within the energy systems of the future was particularly rewarding for the representatives of TEAG.“

Tobias Wurm, Head of Services, TEAG Thüringer Energie AG

IBS - Institut für Brandschutztechnik und Sicherheitsforschung Ges.m.b.H

„The combination of exhibition, workshops and presentations in different formats, as well as the concurrent "eltefa", contributed to the success of the Volta-X. The concept of presenting the topic of energy technologies, starting from storage all the way to sector coupling, in the chosen form to a large group of people and an interested audience of experts, proved to be very effective and was a success. The trade fair was very informative and offered the opportunity to engage in interesting discussions and establish valuable new contacts.“

Josef Hauder, Technician Building Material and Component Testing, IBS - Institut für Brandschutztechnik und Sicherheitsforschung Ges.m.b.H

BayWa r.e. Solar Energy Systems GmbH

„From our point of view, the premiere of the VoltaX was a real success! An excellent platform to present the topics pertaining to sector coupling with all the correlated aspects and to gather  insightful information. We look forward to the next event and the on-site interactions in order to represent the solutions around renewable energy and all their possibilities.“
