Intern in Electricity Market Simulations (80-100%) - 1495

Ensuring electricity in Switzerland

In this exciting internship, your task will be to build on existing preliminary work and implement rolling market simulations. In addition to data research and preparation, this also includes modeling in an electricity market simulation tool, validating and visualizing the results, as well as implementing suitable interfaces to other processes. The scope of tasks includes:

• Learning the basic operation of the electricity market simulation tool
• Learning or deepening the Python programming language through practical applications
• Verifying existing data sources
• Identifying further potential data sources (internal and external)
• Conducting electricity market simulations, possibly also in ongoing projects
• Validating the results through appropriate visualization
• Implementing interfaces to other processes such as network modeling
• Documenting the implemented processes

This is how you make a difference

We are looking for an upbeat personality with high motivation and an independent and analytical working style. You are interested in independently familiarizing yourself with new topics and linking the results with the work started by your predecessors. You enjoy supporting any development work in the implementation of a new electricity market simulation tool. For these tasks, you bring the following:

• Student or graduate (e.g., electrical engineering, computer science, mathematics, physics, economics (University/ETH/FH)) with a Bachelor’s or Master’s degree
• Interest in energy economic topics
• Advanced knowledge of the Python programming language is a plus
• Initial experience in conducting electricity market simulations is an advantage
• Language skills: Very good German or English, French is a plus

This is how we inspire you

We offer you versatile and exciting tasks in a company unique to Switzerland. In addition, you benefit from the following perks:

• Flexible working hours (42 hours per week) in a motivated team
• 25 working days of vacation plus company holidays between Christmas and New Year
• State-of-the-art working environment in close proximity to Aarau train station
• Professional experience in the energy sector and insight into the tasks of a transmission system operator

About us

We are a dynamic, interdisciplinary team of 8 employees working on various topics at the interface of economics and technology.

We conduct market simulations, economic analyses, and (project) evaluations while ensuring the consideration of Swiss interests. Furthermore, we develop the framework conditions for grid usage and ensure that the legal, regulatory, and contractual foundations are adhered to in the implementation of grid usage.

We always have an open ear for the concerns of colleagues and support each other in handling our tasks. We celebrate our successes together and are not discouraged by rare failures but learn from them. Despite the numerous tasks, we also find time for informal exchange beyond professional topics.
