Engie Solutions: Large-Scale Energy Maintenance

Since January 1st, 2020, Engie Solutions has brought together all B2B energy activities of the Engie Group, organized into three customer-focused business units: Cities & Local Authorities, Industries, and Tertiary & Proximity. Across France, 7,000 technicians and agents maintain client installations: building boiler rooms, industrial cooling towers, cogeneration systems, and heating and cooling networks.

For more than ten years, Engie Solutions has relied on Nomadia Field Service Management to orchestrate intervention planning, used daily by its scheduling teams in every branch.

The Challenges: Planning Thousands of Regulatory and Corrective Interventions

📋 Regulatory visits with variable frequency: each installation is subject to a set of environmental, operational, and safety regulations, with intervention frequencies ranging from weekly to annual depending on the site type and contract.
🚨 Simultaneous management of preventive and corrective work: on top of scheduled interventions come unplanned breakdowns and malfunctions, which must be handled urgently without destabilizing the existing schedule.
🎓 Specific skills required by installation type: the monitoring protocols for a 24/7 industrial site bear no comparison with those for a residential boiler room. Each intervention must be assigned to the right technician with the right qualifications.
🗺️ Route optimization for autonomous field technicians: each technician has their own vehicle, tools, and spare parts. Their weekly schedule must be geographically coherent and balanced in terms of workload.

Patrick Hourqueig, Tools & Methods Manager: 10 Years of Collaboration

Patrick Hourqueig has been managing the implementation and oversight of Engie Solutions' scheduling system for 20 years. He explains how Nomadia Field Service has become the central tool of its scheduling teams.

Q How are your field resources organized, and who uses Nomadia Field Service on a daily basis?

Each installation is managed by a local branch. Field technicians receive their schedule every Friday for the following week. This schedule is drawn up by the branch's scheduling team, taking into account the full workload, skill requirements, client time constraints, the theoretical duration of each intervention, and the legal length of the working day. Nomadia Field Service is used by schedulers, dispatchers, and Performance Energy Managers, each with their own role in the planning chain.

Q How are urgent corrective interventions managed in real time?

The dispatcher receives and analyzes the client request. If the intervention is not urgent, it is inserted into the planned activity of the technician responsible for the installation and, where possible, merged with the nearest scheduled intervention. In urgent cases, the intervention is automatically assigned to the technician dedicated to corrective operations. Performance Energy Managers can also trigger an immediate intervention if they detect an operating anomaly, even before the client notices.

Q What is the most significant change after 10 years of using Nomadia?

The major change has been moving to daily technician scheduling. Before, they had their schedule for a month and had to manage completely on their own. We knew interventions were being carried out, but not exactly what had actually been done. This made it difficult to submit activity reports and regulatory call reports to clients on time. Today, technicians access their daily schedule via a tablet interfaced with Nomadia Field Service, and report their hours and call reports in real time. Paper forms have disappeared.

The major change has been moving to daily weekly scheduling of technician activity. Before, they had their schedule for a month and had to manage completely on their own. We knew interventions were being carried out, but not exactly what had actually been done. We therefore had difficulty producing and submitting activity reports and regulatory inspection call reports to clients on time. Today, we are virtually paperless.
