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)

“The four months spent at the heart of Challoch Energy have allowed me to discover the inner workings of the renewables energy sector. Being a part of such a close team/family made it possible to collaborate and communicate easily but also to be involved in many different projects from the start. In my case, I was able to research and build techno-economic models for green hydrogen, wind turbine technologies and low-carbon heat networks. Finally, despite the particular circumstances caused by the Covid-19 virus, the company adapted swiftly, kept everyone’s spirits up and continued to positively impact the industry."  Nick Dewachter (January 2020 - May 2020)

"I worked at Challoch Energy for 6 months. During my time here I work on many projects, with a focus on the PACE project. Through this I learnt a lot about the technical side of renewable energies and cogeneration, notably around gas and electrical grid connection. Through this, and my education, I now have a good general knowledge of renewable energies and low carbon sources. I developed numerous skills by working on a real project, these skills will be especially useful when going into my next job. The team was very nice and welcoming and were always there whenever I had a question".  Jason Forster (September 2019 - February 2020)

"I interned at Challoch Energy for 6 months. Not only was I able to put my skills in practice, but I was able to learn how a consulting firm tackles its projects. The close-nit team at Challoch is welcoming, helpful and a source of knowledge that is invaluable. Working at Challoch, I had the freedom to perform my tasks with my own methodology but I also had the guidance of all my co-workers every time that I needed it. It was the perfect balance of self-management and group mentoring, as everyone in the team is ready to help and give advice".  Adriana Calderin (August 2019 - January 2020)

"Working at Challoch has given me the experience to apply what I have learned at university to a real-life project and gain an insight into the process of implementing a project. I feel like I have developed skills by working on a real project which I will be able to use going forward. I also have more of an idea of what I would like to do in the future after completing this internship".  David McCallum (June 2019 - August 2019)

"At Challoch, the small team allows for the intern to ask questions on the go and thus learn very quickly. In Challoch, I gained a lot of expertise in areas such as techno-economic studies, energy policies,technical due diligence and financial modelling."  Miguel Tavares (January 2019 - June 2019)

“Working with Challoch Energy enabled me to work on a broad range of renewable energy-related topics alongside receiving consistent support from senior staff. I was able to use my university knowledge and apply it to help clients benefit from renewables. This has helped me gain a better idea about what I would like to do in the future.”  Andrew Keys (August 2018 - October 2018)
