Context of the Supply Portfolio Management (SPM) – Strategic Importance

SPM plays a vital role in modeling and hedging energy risks for client portfolios. The function is evolving from locally fragmented teams to a more centralized, harmonized approach. Key transformation initiatives include:

Establishing a central SPM entity to develop consistent methods and tools

Building a collaborative, cross-geography SPM community

Supporting career growth for portfolio managers

Promoting best practices and unified risk representation

Implementing scalable, automated systems for improved forecasting, pricing, and contract management

Our teams are committed to fostering a culture of collaboration, knowledge sharing, and continual improvement, ensuring both global alignment and local value creation for ENGIE’s clients and stakeholders.

Within SPM the transversal domainTrueWattsis in charge of:

gathering people in charge of actuals consumption management

build expertise on data modeling and grid error management

designthe MPD features andsupportits deployment(MDP isthe product in charge of metering data management in Engie)

This domain is composed of several operational Middle Offices, in charge of certifying the actuals (balancing and billing volumes)for all Supply processes, leveraging the use of MDP.

Additionally,the core product team is the small data science team in charge of designing the core features that will be industrialized by MDP IT teams.The features support all the grid data imperfections: holes in timeseries, inconsistencies between sources, etc. From thedetection of inconsistencypatternsto the correctionalgorithm, this team is charge of settling the common framework use through all the B2B countries.

About theTrueWattsTeam within SPM

TheTrueWattsdomain is a dynamicandcross-functional teams at the heart of Supply Portfolio Management (SPM), dedicated to delivering excellence in actual consumption management. Our mission is to bring together expertsof dedicated Middle Officestocertify actual consumption volumes—balancing and billing—for every Supply process.

TheTrueWattsdomainplays a pivotal role in designing and deploying the MPD(Bee Stonemetering data management product)for ENGIE. We support its implementation by developing innovative features and ensuring best practices are shared across all operational Middle Offices, making full use of MPD’s capabilities.

At the core ofTrueWattsis a focused data science team that creates and refines the foundational algorithms poweringtheMPDcuration pack. We tackle challenges such as gaps in time series data, inconsistencies between sources, and grid data imperfections. Our work ranges from detecting patterns of inconsistency to building correction algorithms, establishing a robust framework that is applied across all ENGIE’s B2B operations worldwide.

JoiningTrueWattsmeans being part of an innovative and collaborative environment, where your contributions will directly drive the energy data reliability and help shapegreen and competitive offers. If you’re excited by solving complex data challenges and making a real impact on the energy sector,theTrueWattsdomainis the place for you.
