Past interns

“I started at Challoch during the uncertain transition period between the pandemic and normalcy, but it didn’t matter as the team was so warm and welcoming! I got to work on a Local Energy Market project, creating the specifications for a Local Energy Operating System. At all times, the team supported and guided me. They also gave me space to take a lot of responsibility myself and allowed me to bring my own expertise and ideas to the project. Challoch is a forward thinking team working on concrete, cutting edge decarbonisation projects with interesting stakeholders. I wouldn’t change my four months with Challoch to anything!”  Juha Köykkä (June 2021 – September 2021)

“Working at Challoch Energy was a great way to improve and develop my skills. I was assigned to many different projects which were interesting to work on and I acquired a real perspective of how the world of work works. Personally, what I liked the most was to be part of a local energy market project, it was really interesting and I learnt a lot. Challoch Energy’s team welcomed me really well and, despite working from home due to Covid 19, I always felt part of the team. They are always in a good mood and are the perfect balance between maximum professionalism and a relaxed atmosphere.” David Ribeiro (January 2021 – April 2021)

“Joining Challoch Energy is above all a great human adventure. The whole team immediately put me at ease and in the best conditions to work. Naturally, this motivated me to give the best of myself to accomplish the tasks that were entrusted to me. In addition to the different tasks I had to perform, I had the chance to develop a LCOE model for three categories of renewable energy: onshore and offshore wind and solar. This allowed me to improve my organisational skills and autonomy. In addition, not a day went by when I didnt learn a little bit more about the renewable energy industry. Indeed the members of Challoch Energy are always available and ready to share their knowledge. I will always have fond memories of my visit, so thank you Challoch!” Natal Santos (March 2020 – August 2020)
