Insider: The building of Europe’s first gigafactory for battery storage systems in 2019 was clearly a decisive milestone since the foundation of the company just under seven years ago. What have been TESVOLT’s other biggest achievements in recent years?
Hannemann: Apart from that, there have been many other highlights. For instance, the many awards we have won, including the German Founder Award in 2018. However, we are above all also proud that we have created high-performance products. The useful life of our products is almost twice as long compared to other systems which are available on the market. This is a definite USP. The fact that we have created such a comprehensive and top-performing product portfolio in only a few years, is probably our biggest achievement.
Insider: What is TESVOLT’S growth strategy for the coming years?
Hannemann: We want to continue to press ahead with our dynamic growth course during the coming years and enhance our visibility further, both nationally and internationally. Our focus is to remain on energy storage in commercial and industrial environments, because this is where some of the highest environmental impacts are generated. Here we can provide obvious benefits. Our clear mission is to make available affordable green electricity anytime, anywhere. With this explicit message we want to substantially expedite the global energy turnaround.
Insider: What are some of the most recent developments and innovations?
Hannemann: One of our major innovations is the active battery management system Active Battery Optimizer (ABO). With this system we have created the only technology of this kind in the world, which optimizes all the cells within the battery. This technology is used in different applications, including for the optimization of self-consumption. Altogether we have now completed 1,500 projects with our energy storage solutions around the world, with market shares between 25 and 40% in different applications.
Insider: What are the biggest challenges right now for companies like TESVOLT and the energy industry in general?
Hannemann: We have little time. The sea levels are rising, the world climate is changing. The impact on ecosystems is enormous. The water is literally up to our neck. The decarbonization of the economic cycles must be pushed ahead much quicker to comply with the meaningful climate goals of the Paris Climate Agreement. This requires joint efforts by the business community, the policymakers, and the society. We must join our forces to save the planet. This sounds dramatic – but all scientifically recognized data confirm that the situation is actually dramatic.
Insider: How has COVID-19 impacted industry (and company) plans?
Hannemann: As challenging as the COVID-19 pandemic may be on a humanitarian level, we have hardly felt any economic impact of the pandemic. We very clearly benefit from the global megatrends of renewable energies and e-mobility and these developments have not been curbed by COVID-19. On the contrary, the environmental awareness of the society has grown once more in the middle of the pandemic. Our internal business processes have likewise almost not been influenced. Thanks to an effective and mature hygiene concept, our production has not stood still. In the areas in which this is possible, our employees also work from home. This works perfectly well thanks to our agile non-hierarchical corporate culture.
Insider: Has it provided an opportunity to increase your customer base?
Hannemann: As a globally networked company we have always strongly relied on digital tools. This has been further reinforced by the pandemic, which is a very clear advantage. On our customers’ level, this has triggered a significant change and they have likewise arrived more strongly in the digital world. Together we can act significantly more flexibly and efficiently in part. Instead of expensive business trips we now communicate mainly via digital channels with our customers or employees working for our subsidiaries in Australia and Korea. The pandemic has accelerated the digital transformation of the world of work and we definitely consider this to be an added value.
Insider: Where do you see the company in 10 years’ time (and beyond)?
Hannemann: In my wishful thinking, by 2031 e-mobility and stationary energy storage systems will no longer be exceptions, but a living reality for many. We’re doing everything possible to be one of the main players proactively driving this positive development.
