Modelling and analysis of the European power system
Artelys is looking for an intern to study the impact of intermittent renewable generation on the European power system.

Joining Artelys

Joining Artelys is first and foremost joining a dynamic and motivated team, a stimulating work environment and taking part in varied and fascinating projects.

Artelys develops the Artelys Crystal software suite whose ambition is to position itself as the world leader in energy system modeling and optimization solutions. Crystal software enables Artelys’ clients to optimize large electrical systems (Crystal Super Grid), optimize energy production and sales strategies (Crystal Energy Planner), analyze the impact of local energy policies (Crystal City), plan maintenance operations (Crystal Resource Optimizer) or even create complex predictive models (Crystal Forecast). Artelys Crystal now has a library of Java components that feeds the suite’s software.


The European energy context is undergoing rapid and profound change. The increasing uptake of renewable energy sources on the electricity markets of significant quantities of energy from renewable sources, offers many economic prospects and could shift the major economic trends in the electricity system.

Moreover, as a significant share of renewable energies are intermittent, their successful integration raises a number of technical and operational issues. For example, in order to encourage Renewable Energy (RE) producers to produce when the power system needs it, some countries such as France and Germany have taken the decision to reform the RE support mechanism.

The switch from a Feed-in-Tariff (FiT) system, where the main unknown factor was the level of production of the PV or wind field, to a system of complementary remuneration, brings an additional uncertainty to renewable energy projects: the spot price of the electricity market. Investors and developers of renewable energy projects must now integrate this variable into their business model, even though the development of intermittent energy sources is gradually distorting the price curve observed on the market (negative prices at certain times of the day, low point around midday when PV production is at its peak, etc.).

In the longer term, the deployment of renewable energies could also lead to the development of other technologies that create synergies between different energy carriers – such as the production of hydrogen by water electrolysis, synthetic methane production or the development of heat pumps in heating networks.

Using the market models developed by Artelys to simulate the supply-demand equilibrium, the trainee will study the long-term evolution of the European electricity mix. Particular attention will be paid to the remuneration conditions of various production technologies or flexibility solutions. The trainee will be part of a team of modeling engineers and economic analysts specialized in the energy sector. In close collaboration with the other members of the team, the trainee will be required to:

  • Participate in the construction of new prospective scenarios.
  • Contribute to enrich the models used by Artelys to simulate and optimize the operations of the energy system.
  • Contribute to the analysis of prospective case studies.
  • Contribute to the writing of study reports and interactions with the customer;
  • Candidates can refer to the study reports published by Artelys to get a first idea of the type of projects on which the trainee will be working.


    Currently pursuing engineering studies, you are looking for an internship, you are interested in the deep transformations of the electrical system and have a good knowledge in mathematical modeling.

    You are looking to apply your technical skills in mathematics/computing to quantitative economic analyses of the energy system. Curious, rigorous and passionate, you show initiative and imagination. You are a team player.

    Required skills:

  • Knowledge of the economics of the electrical system.
  • Mathematical modeling. Good knowledge of linear programming is a plus.
  • Good communication and teamwork skills.
  • Appreciated competence:

  • Python programming
  • Good communication skills in French

    The duration of the internship is 3 to 6 months and will take place in our Paris office. The internship may lead to a job offer.
