Rouen Waste-to-Energy Plant Modernization: Optimizing Energy Performance Without Production Downtime
A key challenge for waste-to-energy facilities
In the context of the energy transition and environmental performance improvement, waste-to-energy (WtE) plants play a strategic role. They enable the conversion of waste into energy while reducing landfill dependency.
Today, these facilities face a dual challenge: enhancing energy performance while ensuring continuous operation, which is essential for efficient waste management at a regional level.
This is precisely the context of the modernization project at the VESTA WtE plant, located in Grand-Quevilly, near Rouen.
A modernization project focused on industrial performance
IESA is contributing to a global modernization program with a clear objective: optimize plant performance while strengthening operational control.
The teams will be involved in integrating upgrades into:
- the control and command system
- the industrial supervision system
These improvements will support:
- ⚡ Enhanced energy performance
- 🔧 Improved control of industrial processes
- 🖥️ Increased monitoring and supervision capabilities
This type of project is fully aligned with current challenges in industrial optimization and digital transformation.
A technical challenge: upgrading without shutting down production
One of the key challenges of this project lies in its operational constraints.
👉 All interventions must be carried out without a full shutdown of the three incineration lines.
This requires:
- thorough upstream preparation
- strong expertise in existing industrial environments
- phased integration strategies (step-by-step deployment, switching, testing)
Such operations highlight the importance of advanced skills in industrial automation and complex system integration.
