Jasper, how did you first hear about E.ON Inhouse Consulting – and why did you choose to do an internship?
I studied Industrial Engineering with a focus on Electrical Power Engineering at RWTH Aachen University. During my studies, I deliberately tried to get to know the energy sector from different perspectives – through working student positions, research assistant roles, and internships.
For me, E.ON Inhouse Consulting was the opportunity to experience the industry from a strategic perspective. I first came into contact with them during a case study workshop at the „aixperienceDays“ at my university. I immediately got a very positive first impression of the team and the company culture: demanding, yet extremely supportive, with a strong focus on constructive feedback. That combination convinced me, so I applied for an internship.
How did you experience your three months as a Visiting Consultant (intern), and what did you work on specifically?
At first, it was definitely outside my comfort zone since my background was more technical. But thanks to the team, I quickly found my footing in the consulting role. The time was intense, dynamic, and challenging in many ways – yet also extremely enriching and diverse.
From the very beginning, I felt like a full member of the team and that I was able to create real value. I worked on a large, strategically important project focused on standardizing grid connection processes for large power generation facilities. It’s a highly relevant and tangible topic, especially with regard to the energy transition.
Fortunately, I joined right at the start of the project, during the conceptual phase, which allowed me to contribute to the content and direction from the beginning.
"Another key factor for me was the steep learning curve and the wide-ranging opportunities for both professional and personal development."
What did you learn the most – both professionally and personally?
Professionally, I learned a lot about the complexity of grid connection processes and the operational realities faced by distribution system operators.
On a personal level, the key learning was about structuring: clearly framing problems and outlining possible solutions, prioritizing tasks, communicating results effectively, and working with different stakeholders.
What was particularly valuable was that I was able to take ownership of my own workstreams fairly quickly, conduct interviews, and even lead small working groups. Because teamwork is highly valued at E.ON Inhouse Consulting, I could always turn to my colleagues for support and challenge ideas whenever needed.
Was there a specific moment when you realized: this is where I want to stay after my internship
There wasn’t a single “aha” moment. Looking back, the decision resulted from several factors. I really enjoyed the company culture and the collaboration within the team – even beyond project work. For example, there were regular team events where you could get to know each other personally and strengthen team cohesion.
Another key factor for me was the steep learning curve and the wide-ranging opportunities for both professional and personal development. I also found it very positive that even as an intern I was given significant responsibility and autonomy – always accompanied by regular feedback. On top of that, I could directly apply many of the topics from my studies.
And of course, actively contributing to the energy transition as part of E.ON and helping shape forward-looking decisions is simply incredibly exciting.
When I received the offer for a full-time position after my internship, the decision was quite easy: this is where I want to stay long term.
"From the very beginning, I felt like a full member of the team and that I was able to create real value."
How did the transition from Visiting Consultant to Consultant work?
My first assignment as a Consultant was actually a follow-up project to my internship, so I was able to quickly reconnect with the topic. I also already knew several team members and partners on the E.ON side, which was a great starting point.
Of course, as a Consultant I had more responsibility for my own deliverables and the “intern safety net” was gone. But I still received a lot of support from the team. Overall, I was able to drive topics much more independently – preparing workshops, developing results, and presenting them.
It was especially motivating that partners on the E.ON side perceived me as a reliable point of contact and approached me directly with content-related questions. The shared identification with the E.ON group and the high level of trust are very motivating.
An absolute highlight when starting as a Consultant was the BCR week (Basic Consulting Readiness Training). Five days full of intensive training, lots of input for the consultant toolkit, and at the same time a great team-building opportunity with other new joiners – everything you need for a successful start in consulting.
How else are you supported as a new joiner at E.ON Inhouse Consulting?
There are several layers of support: a Development Lead for personal and professional development, a buddy for more informal questions about internal processes and organizational matters, and generally an extremely open culture with constant feedback.
The internal network is fantastic, and thanks to many internal initiatives and formats, the barrier to reaching out to others is very low – which helps enormously.
What’s also great is that you really get the freedom to develop. Not everything has to (and won’t 😉) be perfect from the start.
Finally: your tip for students and graduates?
If you’re interested in an internship or a full-time position at E.ON Inhouse Consulting, enthusiasm for the energy sector and the energy transition is definitely important.
You should be open to stepping outside your comfort zone and avoid starting with overly narrow expectations. Also, prepare well for the Recruiting Day so you can present yourself confidently.
And very clearly: take advantage of university events and workshops organized by E.ON Inhouse Consulting! For me, that was the door opener and entry point – and you really have nothing to lose.
