Frioul Islands, Marseille, France

Site presentation

The Aix-Marseille-Provence Metropolis has expressed its determination to become a model region in terms of energy transition. To meet the growing demand for electricity, particularly in its port areas, it is committed to using existing surfaces to generate renewable energy.

Within this framework, Wattway technology has been deployed at the Frioul Islands marina, an iconic site along the Marseille coastline, located at the heart of an archipelago designated as a Natura 2000 area. This project, a world first on a maritime dock, demonstrates a new way of developing renewable energy without requiring additional land use or altering the landscape.

How the
system works

The power plant, installed as an overlay on a concrete dock, consists of 48 Wattway modules, each with a unit capacity of 237 Wp. The equipped surface covers approximately 80 m², providing a total power output of nearly 12 kWp.

The energy produced, estimated at 12,000 kWh per year, is consumed locally: it supplies the port’s equipment, dock terminals, and the harbor master’s office. This short-circuit system avoids losses associated with electricity transmission and enhances the site’s energy self-sufficiency.

Why did the local authority
choose Wattway?

Wattway offers a unique technological solution that respects the landscape and environmental constraints of sensitive sites.
Located within a protected natural area, the Frioul site required a solution with no visual impact and minimal construction work, making Wattway the obvious choice. Easy to integrate onto existing infrastructure, the technology preserves the original function of the surfaces.

This power plant serves as a demonstrator for other ports and coastal communities, showcasing how already developed surfaces such as docks, jetties, or parking areas can be used to generate renewable energy.
