Traineeship Design

Introductie

For October 2026, TenneT is looking for trainees for various areas within TenneT: Operate, Onshore, Offshore, Design, and Digital & Technology Transformation. You can apply for one position only. This role is within the Design Division.

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 an 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.

Jouw rol

Our 18-month International Traineeship Programme is the ideal way to start your career in the energy sector. You will prepare for a future role in our Design division, contributing to long-term system planning, market design, and innovation – all crucial for realising TenneT’s strategic goals. 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;
• Analysing the financial performance of transmission rights on international offshore cables;
• Innovating the way we use our grid by contributing to the development of new products for our customers;
• Exploring how the use of AI can improve grid stability and market transparency.
