Frades 2, Portugal
Frades 2 is a new 780 MW pumped storage hydropower plant in northern Portugal. Commissioned in 2017, the two generator sets are the largest and most powerful of their kind in Europe. Under XFLEX HYDRO, the site will demonstrate an innovative operating regime: hydraulic short circuit operation using variable speed units and smart controls to optimise power services onto the grid network, focusing on fast frequency services.

During the project, the flexibility technologies will be trialled at 7 demonstration sites. These are located at existing European hydropower stations. Each XFLEX HYDRO demonstration site will test a different technological configuration, installed together with the Smart Power Plant Supervisor in every case.
