Sovalis project at a glance
The Sovalis (Solar farm and Vanadium Lithium storage) project aims to develop a large-scale photovoltaic solar power plant, combined with an advanced hybrid energy storage system, designed to maximize the production, integration and efficient conservation of renewable electricity.
By generating a significant amount of solar energy, the project limits the use of fossil fuel-based electricity, reducing greenhouse gas emissions and dependence on imported fossil fuels. With a high-capacity dual-battery system - combining lithium-ion and vanadium redox flow battery (VRFB) technologies - the project guarantees efficient storage of this clean energy during periods of overproduction, as well as its availability during peaks in demand, thus ensuring maximum production.
The combined impact of solar production and innovative storage is expected to result in a reduction of around 253,000 tonnes of CO₂ over the first ten years of the solution's operation, compared with conventional electricity production in Europe.

Sovalis project technical innovations
Sovalis goes beyond current energy storage solutions by using a dual-battery system that takes advantage of the high energy density of lithium-ion, as well as the robust cycling performance and depth of discharge of VRFBs. This dual-battery system offers greater flexibility and extends the life and efficiency of the storage system.
