As an International Trainee in TenneT’s Design Division, you will help shape the energy system of the future. The Design division defines TenneT’s corporate strategy and translates it into integrated, future-proof vision for our electricity system: onshore and offshore. Next to that we facilitate the functioning of electricity markets. Working closely with our customers and stakeholders, we explore future scenarios, anticipate developments, and create the framework that enables the energy transition. In doing so, we ensure that the system we design today will meet the challenges of tomorrow.

Your contribution to TenneT

Our 18-month International Traineeship Programme is the ideal way to start your career in the energy sector.

And you will also have the opportunity to explore other areas of TenneT to broaden your understanding of how the entire electricity system works together.

  • A Tailored Journey – Three rotations, primarily in our Design Division, plus the opportunity to look beyond and gain insights into other areas of TenneT.
  • Impact from Day One – Work on projects that strengthen the grid and accelerate the energy transition.
  • International Exposure – Collaborate across borders and see how onshore and offshore developments fit into the bigger picture.
  • Learning Community – Join a network of trainees, experts and alumni, with training modules and internal consulting projects to boost your development.
  • Shape the Future of Energy – You’ll join the organization that keeps the electricity system balanced 24/7, steers innovation in energy markets, and prepares our grid for more solar, more wind – and more complexity.

As a trainee for our Design Division, you will contribute to projects such as:
  • Developing scenario’s for the Dutch energy system of 2045;
  • Developing an approach to deal with grid losses between offshore hubs;
