Job Description

Excited to work for a key Belgian player in the energy landscape?

The Belgian and European energy landscape is in full swing. Did you know that Elia Belgium plays a crucial role in this? As part of Elia Group, a European transmission system operator, Elia Belgium ensures the reliability and sustainability of the electricity supply in our country.

Side-by-side with your talented colleagues, you will play a part in building a sustainable, green and reliable energy infrastructure that stimulates economic growth and reduces our ecological footprint.

Only together can we make the biggest impact possible! We believe in the power of diversity: we are convinced that an inclusive and diverse work environment leads to more innovation, creativity and better results.
Expert Energy Technology Modelling and Scenarios
Requisition ID:  10721
Posting Start Date:  16/07/2026

Function

 

Elia is strengthening its Scenarios, Market and Adequacy Analysis (SMA) department to address the challenges arising from the evolution of the energy system. This team quantifies and analyses European energy mix scenarios and also carries out numerous studies (public or internal) on the future of the Belgian and European energy systems, security of supply, flexibility, the Belgian transmission network, and interconnection projects.

These studies include security of supply analyses over different time horizons conducted by Elia (the Belgian Capacity Remuneration Mechanism volume proposals, the 10-year Adequacy and Flexibility Study, forward-looking studies on the future energy landscape such as the recent “Blueprint”, etc.) or by ENTSO-E.

The department also performs economic analyses related to high-voltage grid reinforcement, which are used in bilateral projects with other transmission system operators as well as in the context of Elia’s Federal Development Plan and the European TYNDP (Ten-Year Network Development Plan).

The department maintains up-to-date energy mix scenarios covering most of Europe, closely monitors the development of new technologies, and develops various future pathways for the energy system. These scenarios are subsequently used in SMA studies, by other departments within Elia, and even by external stakeholders.

Some of these studies and team achievements are available on the following page of Elia’s website: Elia Studies and Reports

 

Your role

As an Expert Energy Technology Modelling and Scenarios, you contribute to the energy transition by building future scenarios based on available trends, policies, and data. You analyse market developments and participate in forward-looking projects and studies. You will be involved in designing, developing, and maintaining analysis and modelling tools while playing a key role in the IT and data-related aspects within the team.

This includes developing and improving data pipelines, managing large volumes of energy-related data, working with local hourly consumption and production profiles, and potentially integrating and visualising geographical/GIS data. You will also support other analysts in using, industrialising, and improving these tools.

 

Key responsibilities

  • Develop assumptions for long-term European and Belgian scenarios while closely following developments in the energy sector.
  • Monitor the evolution of key technologies driving the energy transition, such as electric vehicles, batteries, industrial electrification, and new forms of flexibility.
  • Develop and improve robust data pipelines to collect, transform, validate, and leverage granular energy data, including local hourly profiles related to consumption, production, injection, and withdrawal.
  • Develop small-scale optimisation models (e.g. residential self-consumption profiles).
  • Combine market, network, location, and hourly profile data to improve the spatial and temporal granularity of the scenarios used in Elia studies.
  • Contribute, within your areas of expertise, to the work of European transmission system operators on security of supply and transmission network development, notably through ENTSO-E or Synergrid.
  • Maintain and develop an expert network within your field.

Your Profile

  • You have at least 5 years of experience in modelling and/or data analysis.
  • You closely follow developments in the Belgian and European energy sectors, understand market trends, and are able to project these into future scenarios. Experience in an energy sector other than electricity is considered an asset.
  • You hold a university degree (Master’s level) in economics, engineering, business, mathematics, or data analysis.
  • You communicate clearly and concisely and can adapt your communication style to different audiences.
  • Experience in economic and/or market analysis, preferably within the energy sector, is an asset.
  • You have knowledge and/or experience in statistics, econometrics, and mathematical optimisation. Experience with energy modelling and optimisation tools (e.g. PyPSA, Antares, Linopy, or equivalent) is considered a major asset.
  • You have proven programming experience, particularly in Python (mandatory), and have a strong affinity with data processing (data science and data engineering), data pipeline development, automation of analyses, and time-series data handling.
  • Knowledge of GIS tools or concepts is considered an asset.
  • You are able to work both independently and collaboratively, with a strong sense of ownership for tools and strategic projects.
  • You are comfortable using artificial intelligence tools (e.g. for software development, data analysis, or automation) and can apply them in a structured way to improve efficiency and the quality of analyses.
  • You have an analytical and innovative mindset.
  • You are fluent in French or Dutch and have a good command of English (the working language of the team).
  • You are comfortable working with Microsoft 365 tools (Word, Excel, SharePoint, etc.).

Offer

 

  • Salary: a competitive salary package, allowance for representation expenses, year-end bonus, double vacation pay, meal vouchers (€10 per working day), eco-vouchers, sport & culture vouchers, bonuses based on individual and group results. 
  • Insurance: group insurance, hospitalisation insurance, ambulant care insurance for the whole family and also personal accident insurance. 
  • Vacation: You will be entitled to 20 vacation days and 5 additional vacation days, 6 local days, 4 exempt days (after 1 year of employment) and up to 5 long-service days (1 day for every 3 years in employment). 
  • Social fund: Year-end vouchers, birth and marriage allowance. We will also cover part of the cost of glasses, a dental prosthesis or similar needs. 
  • Communication: you will be given an iPhone, a phone subscription (for work and private use) and a laptop with internet reimbursement.
