Context
In this position you will be part of Supply Portfolio Management. Supply Portfolio Management (SPM) encompasses the key activities required to optimize and manage an energy supply portfolio. This includes forecasting of energy consumption, pricing strategies, grid data acquisition and analysis, and ensuring accurate portfolio representation on energy markets.
SPM also involves collaboration with central teams to support local or global projects, harmonize methodologies, and share best practices. The role fosters strong connections with other supply entities to address common challenges, improve performance, and align organizational approaches.
Role
As a Forecasting Team Member, you will contribute to the development and delivery of forecasting processes and models that support the energy supply business. Working under the guidance of the Forecasting Local Leader, you will collaborate closely with portfolio managers, pricers, and other business stakeholders to ensure forecasting outputs are accurate, timely, and aligned with operational needs. Your work will be based on rigorous data collection and analysis, and will directly contribute to optimizing costing, forecasting, sourcing, and hedging strategies within a defined business mandate.
You will be actively involved in the design, implementation, and continuous improvement of forecasting tools and methodologies, ensuring alignment with global standards and contributing to their evolution. Your role will also include cross‐functional collaboration within the SPM community and with forecasting teams in other countries to promote knowledge sharing and consistency.
You will be responsible not only for the technical development of forecasting solutions but also for ensuring their operational reliability and relevance to business needs. This includes representing the dynamics of supply portfolios—such as commercial position evolution, climatic impacts on consumption forecasts, and customer behavior analysis—and supporting the development of new commercial offers.
In addition to model development, you will provide scientific expertise for bespoke analyses and contribute to the continuous improvement of forecasting practices. A solid understanding of energy market design (B2C and B2B regulation, sourcing mechanisms, and supply reliability) is essential to successfully carry out these missions.
Key Responsibilities
- Model and Process Development: Contribute to the design, implementation, and continuous improvement of forecasting tools, models, and processes used to support the energy supply business.
