Flexibility Needs Assessment Expert

Function

Elia is strengthening its « Scenarios, Market and Adequacy Analysis (SMA) » department to address the challenges of the changing energy system. This department analyses developments within the Belgian and European energy system and carries out studies on the energy future, security of supply, flexibility, the transmission grid and interconnection projects.

As a Flexibility Needs Assessment Expert, you will contribute directly to the energy transition by helping to determine how much flexibility the Belgian electricity system will need in the future.

You will be part of the team responsible for Elia's Flexibility Needs Assessment (FNA), a forward-looking study that assesses the flexibility needs of the Belgian electricity system. Driven by European regulation, this assessment is carried out every two years and provides important insights for Elia and its stakeholders, including regulators, distribution system operators, public authorities and market parties.

With the next FNA to be delivered in 2028, you will have the opportunity to contribute to a highly visible study with a tangible impact on the future Belgian energy system. Your role combines quantitative analysis and modelling with methodology development, stakeholder management and project leadership.

In addition, you will take follow up with colleagues on the development of flexibility in the system, advising colleagues on to improve scenarios and expectations on adequacy, flexibility and balancing needs, to develop short-term forecasts on available flexibility, shortages and identify mitigation measures and to define market and product strategy recommendations on the development of flexibility.
