Requisition ID:  10154
Posting Start Date:  17/09/2025

Function Description

The Customers, Markets and System (CMS) department supports the path towards a carbon-neutral society by embracing the role of policy advisor and customer partner, and by designing the ‘system of the future’ in which the consumer is central. At the same time, CMS guarantees the safe operation of the electricity grid by optimizing the use of assets, improving our system understanding, developing methods and tools to address stability challenges, automating complex tasks, and using production and flexibility tools to implement a new market design and a strong price signal.This decarbonization process brings several challenges:

 

  • TSOs must ensure that the onshore and offshore system is designed and developed in a way that enables the timely integration of renewable energy sources and storage, while simultaneously guaranteeing the safe operation of the system.
  • A paradigm shift is needed: from a supplier-focused market design, where flexibility is provided by suppliers, towards a consumer-oriented, enhanced market design that unlocks flexibility. Therefore, a customer-centric mindset is essential: we need to be closer than ever to our customers in order to identify their deepest needs, shape the energy transition together with them, anticipate the impact of their electrification on the grid, and connect them more quickly.
  • Affordability and cost efficiency need to be ensured and anchored in our core activities, so that we can maximize well-being, control costs, and at the same time guarantee availability, safe system operation, and timely network development.

 

As a Portfolio Manager, you will join the local strategy implementation and transformation team (SITO) for Elia Transmission Belgium. This transversal department forms the bridge between local execution (serving the different departments: CMS/Infrastructure/Assets—together with Business Architects, Business Analysts, Program and Project Managers, the PMO team, and a Performance Manager) and alignment at Elia Group level.
