FERRATI V4 GREEN AC

Highly involved in topics relating to the energy transition, the commune of Le Ferré has committed to encouraging renewable energies and self-consumption wherever possible, and to strive towards the commune’s energy self-sufficiency.

This is why they decided to implement the FERRATI V4 GREEN AC project, a photovoltaic solar scheme in a rural area, based on a collaborative self-consumption project in which the commune will hold the status of Legal organising party, combining:
•    PV panels on the rooftops of 3 buildings (associated with renovation works) for 34 kWp,
•    An electrochemical storage system (Lithium-Ion battery),
•    Management of the entire system,

The project will be deployed over 10 municipal buildings with a range of different use types:
-    Municipal bar-restaurant, professional premises, village hall (production – consumption)
-    Youth centre, town hall, church, sports changing rooms, municipal workshop (consumption)
-    Public lighting system.

The production of fully saleable electricity through PV panels on the roof of another building (9 kWp) completes this collaborative self-consumption project.

The target is to achieve around 45% energy self-sufficiency.

Project objectives:

Techniques :

Develop new techniques around photovoltaics on 3 main themes: collaborative self-consumption, dynamic energy management and electrochemical storage

-    4 photovoltaic generators on rooftops for a total supply of 43 kWp

-    1 Lithium-Ion storage unit, BMS (Battery Management System) representing 40 kWh providing a maximum supply of 15 kVA

-    5 meters communicating across 12 identified consumption sites

-    A global supervision system ESE VIEW + EMS (Energy Management System)

Energy related: The annual consumption of all these sites combined is 80,000 kWh. As the annual production of 3 collaborative self-consumption generators is estimated at around 36,000 kWh, the aim is to reach a level of energy self-sufficiency of around 45%.

Environmental: Sustainable development with renewable energy: photovoltaics

Commercial: Sell the energy produced on certain buildings

Economic: Implement self-consumption and control a portion of the energy consumption at a stable cost for the next 20 years. The electricity costs for the different sites have increased by 6%/year since 2017.

User involvement: Initiation of the lessee manager on the topic of self-consumption.

Added value of the project :

A project on the scale of a rural commune, it encourages the integration of renewable energies and the balance between production and consumption. Through collaborative self-consumption and the resale of surplus energy, it is possible to achieve economic equilibrium.
