The General Directorate of Energy of the Government of the Canary Islands has opened to public consultation the administrative request of Red Eléctrica de España S.A.U. to install a grid forming voltage control system, a technology that allows renewable energy sources to create their own grid, in the Mácher substation (Tías). This system would be based on hybrid storage.
This request from Red Eléctrica de España was registered with the Government of the Canary Islands in May 2024. It aims to develop the VISYNC project. According to its website, this initiative seeks to develop, on a real scale, a storage system that combines lithium-ion batteries and ultracapacitors managed by a specific control system.
The creation of this storage system in Lanzarote is promoted by up to seven Spanish companies (Red Eléctrica, Elewit, Hesstec, Cen Solutions, S2 Grupo, and UL Solutions). As those responsible for the project defend on their websites, its installation seeks to combat the archipelago's limitation in the penetration of renewables due to its distance from the peninsula.
This system seeks to guarantee the safe operation of the electrical system and increase the "integration of renewable energies" in Lanzarote and Fuerteventura.
