2. Challenges for Poissy Intercommunal Hospital Center (CHI)

Site sensitivity: As a hospital, any interruption to the power supply could have serious consequences for critical medical equipment.
Obsolescence of the existing system: The initial controller , a GENSYS 1, could no longer guarantee optimal management of the generator and the power grid.
Modernization and compliance: Adapting the backup power plant to comply with current standards and ensure reliable long-term operation.

The solution we provided

To comply the specific needs of Poissy Intercommunal Hospital Center (CHI) and ENGIE, we implemented the following steps:

1. Detailed audit of the existing installation

Analysis of the equipment in place, identification of weaknesses and needs.

2. Advice and recommendations

Proposal of an adapted solution with replacement of the CRE GENSYS 1 controller by a CRE GENSYS COMPACT MAINS controller.

3. Complete redesign of the electrical diagrams

Complete overhaul of the control diagrams for improved reliability and up-to-date documentation.

4. Development of the new controller program

Customized programming to optimally manage the generator and mains.
