Etienne Grégoire Diouf

At ENGIE Solutions, I analyse electricity, gas and water data across industrial facilities to uncover load patterns, anomalies and energy-saving opportunities. I build KPIs, baselines, Pareto analyses, and Excel and Power BI dashboards that help teams prioritise optimisation actions.

I validate utility metering systems, assess active and reactive power measurements, and investigate gaps between expected and measured performance. My work also covers compressed air, HVAC, pumps, control systems, and BMS/BACS operating strategies.

Previously at CDC Conseil, I conducted energy audits and dynamic modelling for tertiary and public buildings. One retrofit pathway I identified delivered up to 57% final-energy savings and approximately 70% CO₂ reduction.

I'm increasingly focused on power systems, electricity markets, grid flexibility, renewable integration, and the energy transition, supported by experience in technical-economic assessment, reporting, and cross-functional project coordination.
