Trainee Operate

Start je carrière in de energiesector als International Trainee Operate bij TenneT’s Operate Division

For April 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 a Trainee Operate.

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.

As a trainee for our Operate Division, you will contribute to projects such as:

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

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.

We’re looking for graduates who want to design the future of the energy transition.

• Education – A Masters degree in Electrical Engineering, (Applied) Physics or (Applied) Mathematics.
• Analytical & Innovative – You combine strong analytical skills with innovative abilities to develop solutions for complex challenges.
• Energy Curiosity – You are fascinated by the challenges and opportunities for sustainable technology and large-scale infrastructure.
• Language – Proficiency in English is required, learning Dutch is not mandatory at entry, but learning Dutch will be part of your development during the traineeship.
• Flexibility – Open to travel and working at different TenneT locations.
• Residence – Because you’ll be working in the office 2-3 days per week, you need to live in the Netherlands during the traineeship. You’ll also join us in person for the recruitment day for the selection process.
• Experience – Internships or relevant work experience are a plus.
