Alqueva is a pumped storage scheme in southern Portugal that was built in two phases, Alqueva I and II, now totalling 520 MW. The first station was operational in 2004 and the second commissioned more recently in 2017, each installed with two reversible Francis pump-turbines. At the site, the XFLEX HYDRO project aims to use hydraulic short circuit, extended operating range and smart controls to improve the flexibility provided to the grid – not only in terms of frequency services, but also voltage support.
Evaluate low CAPEX opportunities to extend services offered by an existing pumped storage plant and compare them to a conversion to variable speed, namely:
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.
