Cheviré solar power plant

The 2.44 MWc photovoltaic power plant has been installed in the Cheviré port zone, in the heart of the metropolitan Nantes. The roofs of three storage hangars belonging to the logistics company Sogebras now produce 2650 MWh of solar energy per year.

The project, completed on behalf of our client JPEE, had particular technical constraints. Our in-house design office thus optimised the overall electrical architecture, in particular with transformers distributed over the site, medium voltage connections on-site and fuse protection integrated into the transformers, allowing just a single cable to be used thus avoiding the installation of an HV distribution board in the transformer stations.

The results of this optimisation have been to optimise investment costs, to increase the yield of the installation and to inject more solar power into the grid throughout the service life of the plant. The Low Voltage Switch Boards have all been assembled in our workshops in Quimper where they have been tested and powered up, this guaranteeing competitiveness and the control of deadlines and quality. We have also produced all of the technical rooms adapted to the constraints of the site.

The energy is injected into the grid and helps to power the Bouguenais industrial zone.
