Service Description

The proper functioning of the electricity market is one of the key elements in the energy transition. Our client plays a central role in facilitating the market and is responsible, among other things, for numerous services designed to ensure reliable operation of the electricity system. A crucial facilitator is flexibility referring to the extent to which a power system can modify electricity production or consumption in response to variability, expected or otherwise.

Within the Customers department, the Flexibility Studies team is responsible to assess the flexibility needs and flexibility ressources (storage, generation, demand response) of the system by means. One of their activities is to quantify the current installed, unlocked and available flexibility delivered per technology, voltage level and product type. This initiative is referred internally to as the “Flexibility Track and Trace Initiative”. The results are used to:

  • Improve our client’s long-term projections on adequacy, flexibility and balancing needs
  • Improve our client’s short-term forecasts on flexibility shortages and mitigation measures
  • Provide strategy recommendations on the development of flexibility

The initiative was launched in 2024 to enhance our client’s ability to systematically monitor and predict flexibility of our system across various future time horizons. This requires to gather flexibility information from assets on the High voltage Grid, as well as the Medium and Low voltage DSO grid. The latter will require collaboration with DSOs and market players.

Our client needs to accumulate information on load and/or flexibility capabilities from Electric Vehicles, Batteries, Heat Pumps, and Photovoltaics but also from industrial processes (electric boilers, heat pumps, electric ovens) on high, medium and low voltage grids. This entails on the one hand their participtation in our client’s balancing services via activation signals, and on the other hand reaction on price signals given by day-ahead, intra-day and balancing markets.

Our client is now looking for an experienced analyst to join the Flexibility Track and Trace Initiative. Within the team (consisting of two junior analysts and a manager) The consultant will contribute both to the project management and the analysis of flexibility in the system.

  • The consultant will be expected to develop and execute strategies to seek information through desktop research (regulators' websites…), contacting market parties (distribution system operators, sector federations…) or devising and working out inventive ways to retrieve unavailable information.
  • The consultant will be expected to conduct analyses on available time series of grid user consumption data (including data from smart meters), renewable energy forecast errors, market player behavior (nominations and their adjustments) and system imbalances. The consultant can apply basic statistical analysis and machine learning techniques where needed.

  • (support) gathering information on available flexibility through various channels (desktop research, interviews, data analysis, estimation methods);
  • (support) the developing and conducting data analysis on smart metering data (consumer offtake and injections) as well as determining the relationship with system conditions, seasonality or other drivers.
  • Forsee the communication and dissemination of results and insights for different target audiences (experts, management, external).
