Traineeship Operate

Introductie

For October 2026, we are 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 Operate division.

As an International Trainee in TenneT’s Operate Division, you’ll be part of the team that keeps the lights on – 24/7. The Operate division ensures that our high-voltage grid remains stable, secure, and compliant, safeguarding power, voltage, frequency, and stability limits at all times. The division is responsible for real-time system operation — continuously monitoring, balancing, and controlling electricity flows to keep supply and demand in balance.

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 Operate division, where you will contribute to real-time system operation, balancing, and market coordination, helping to integrate more renewable energy in the grid. You will gain hands-on experience in how TenneT ensures a reliable electricity system today – and prepares it for the challenges of tomorrow – while also exploring other areas of our organisation to broaden your perspective.

• A Tailored Journey – Three rotations, primarily in our Operate division, plus the opportunity to look beyond and gain insights into other areas of TenneT.
• Impact from Day One – Work on real 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 Operate Division, you will contribute to projects such as:

• Improving real-time frequency balancing to keep the grid stable;
• Optimizing voltage control to maintain power quality;
• Developing market monitoring tools to detect potential market abuses;
• Applying data analytics to strengthen system and market surveillance.
