'We used to consume energy; today, we manage it'
For 40 years, Janitza has helped shape the evolution of modern power infrastructure. Today, digitalisation, electrification, and increasingly volatile power grids are fundamentally changing requirements for visibility, availability, and power quality. In this interview, Alexander Veidt (pictured above), CEO at Janitza, explains the challenges arising from these developments and how the company is positioning itself for the energy infrastructure of the future:
DCNN: Power infrastructure worldwide is becoming increasingly complex, dynamic, and data driven. Which trends are driving this transformation the most?
Alexander: I see three key developments. First, we are seeing large-scale electrification of industry, buildings, transportation, and heating systems. Second, there is increasing decentralisation and volatility driven by renewable energy sources, energy storage systems, and flexible loads. Third, there is a growing need for transparency because energy is no longer just a cost factor; it has become a strategic business resource.
All of this is leading to a fundamental shift. We used to consume energy; today, we manage it. We need to know where the energy comes from, when it is available, and how we can control it, store it, or send it back to the grid.
DCNN: Electrification is pushing power grids to their limits in many parts of the world. Is the key question ultimately whether enough energy is available?
Alexander: That is certainly a central question. Equally important, however, is the question of power quality. We have been focused on power quality for 40 years, and one thing is becoming increasingly clear: power quality is deteriorating.
DCNN: What specific issues are you seeing?
Alexander: One example is grid frequency. Conventional power plants create a physically stable and inert grid through their rotating masses. Today, many renewable energy sources feed power into the grid through power electronics and inverter technologies. As a result, grid behaviour is changing compared to traditional systems based on large rotating generators.
DCNN: How are AI data centres intensifying these challenges?
Alexander: At the end of the day, data centres are major energy consumers. However, when it comes to AI data centres, a new question is emerging: Do we have the right power quality, at the right time, in the right place, and can we control it reliably?
In addition, we should not overlook the fact that data centres also influence the power grid itself. During AI training runs or sudden demand spikes, significant and rapid changes in power demand can place considerable stress on the electrical network.
DCNN: Janitza has been developing solutions for its customers for 40 years. How is the company evolving its products to address these new requirements?Alexander: Our UMG 512-PRO Power Quality Analyzer is a comprehensive solution with a strong track record in the market. Additionally, we are preparing to launch the next generation of our measurement devices, designed specifically to address the issues we have just discussed.
What’s more, this applies across all voltage levels. For each level, we offer dedicated product families capable of detecting these issues, processing the data, and helping customers manage them while addressing the specific characteristics of each grid environment.
DCNN: We have talked about AI in data centres. What role will AI play in Janitza’s portfolio in the coming years?
Alexander: AI will play a major role. One of our advantages is that Janitza solutions generate data, and data is the foundation for training AI models. Only then can large volumes of data be used effectively for monitoring, control, optimisation, and automation. We are already implementing AI applications, including within GridVis (our energy monitoring and power quality analysis software) and in planning tools for electrical infrastructure.
Janitza has made energy data visible to its customers across every generation of our products. Access to data is not the issue; AI takes the analysis of these vast volumes of measurement data to an entirely new level and makes that information significantly more actionable.
DCNN: As power grids become more complex, companies around the world are also facing increasing regulatory pressure. Which issues are currently top of mind for your customers?
Alexander: I see two primary issues. The first is sustainability: reducing CO₂ emissions and lowering energy consumption, driven by regulatory requirements and compliance deadlines.
The second is the growing international influence of regulatory frameworks. Today, we can clearly see how regulations established in one region increasingly affect companies in other parts of the world.
DCNN: In this dynamic environment, where do you see the greatest growth opportunities for Janitza over the next several years, particularly on an international level?
Alexander: Everywhere electrical infrastructure is critical, complex, and closely tied to economic growth. That includes data centres, industrial facilities, energy infrastructure, healthcare, and large commercial buildings. North America will remain one of our most important strategic markets, particularly because it is home to the world's largest data centre ecosystem.
At the same time, we will continue to diversify our business and expand into new industries. Each region we are targeting faces its own challenges. We understand those challenges and know how to address them in different ways. That positions us well for continued growth.
DCNN: Janitza celebrates its 40th anniversary in 2026. What can customers continue to expect from Janitza in the years ahead?
Alexander: For us, Janitza’s 40th anniversary is both an opportunity to reflect on what we have achieved and a starting point for the next stage of our development. Over the years, we have built a strong commitment to quality and innovation that our customers can continue to rely on. At the same time, we are investing heavily to ensure that we remain among the technology leaders in our industry.
Our customers can count on Janitza to remain the innovative specialist in energy measurement technology. This is our passion.
