ALTO RABAGÃO: HYDRO & SOLAR

Located in Montalegre, Portugal, this 218 kWp floating solar plant is the first project installed on a hydroelectric dam with an area of 22 km² (2,212 ha). 

The platform is equipped with Classic version of Hydrelio® technology and supports 840 floating solar panels of 60 cells (260W REC standard modules). The total structure covers 0.01% of the water surface. 

For this project, Ciel & Terre enrolled as an EPC contractor, supervising the engineering, procurement and construction of all the floating PV structure and the anchorage. Our scope included:

• Supply of our Hydrelio® (made in France) and design of the floating platform
• Design, supply and installation of the anchoring solution
• Design of the electrical equipment 

Anchored at the bottom of the pond, the very specific anchoring solution here has been designed to meet a maximum 60 m depth while dealing with a 30-m water level variation (currently the most challenging anchoring system ever build for a floating PV project). 

Alto Rabagão’s floating solar plant has been operational since November 2016 and generates green electricity to the local grid.
