EDP commissions 5 MW floating PV as blueprint for 70 MW project

Portuguese energy group EDP (Energias de Portugal) has commissioned a 5 megawatt (MW) floating solar power plant on the reservoir of the Alqueva Dam. The plant, completed after seven months of construction, »was also critical in accelerating the creation of new investment opportunities in clean technologies and opening doors to auctions that contribute to the urgent acceleration of renewable energies,« according to a statement referring to a much larger project at the same site: In April, EDP won Portugal’s first tender for floating photovoltaics (FPV) plants, for a 70-megawatt power plant in Alqueva.
The plant, which has now been completed and for which EDP has stated an investment of €6 million ($6.1 million), covers an area of four hectares and is expected to generate an annual yield of 7.5 gigawatt-hours, or 1,500 kilowatt-hours per kilowatt of installed capacity. Plans also call for the addition of a 1 MW battery storage system with two megawatt-hours of storage capacity. Solar power production on the reservoir will use the grid connection point of the dam’s pumped storage power plant.
Supplied by the Spanish company Isigenere, the FPV system’s floats are made of recycled plastic and cork. This solution, tested for the first time in Alqueva, is the result of a partnership with the Portuguese manufacturer of wine corks Corticeira Amorim.
