Endesa ‘s Son Orlandis storage facility could represent a step forward in the European renewable energy sector. Using vanadium flux batteries, this technology enables greater flexibility and modularity, essential for maintaining a stable energy supply. Its storage capacity of 1.1 MW and 5.5 MWh makes it the largest installation of its kind for a photovoltaic power plant on the continent. This project is supported by the SOLBAL photovoltaic investment program, managed by the Institute for Diversification and Energy Savings (IDAE).

A strategic partnership

The development of the Son Orlandis battery system is the result of a collaboration between Endesa, through its subsidiary Enel Green Power España, and Largo Clean Energy. These storage systems are durable, with an electrolyte that lasts almost indefinitely. This approach can ensure a stable source of energy, even during peaks in demand, through optimized management of loading and unloading.

Strengthening energy stability

The Son Orlandis storage system plays a key role in stabilizing the Balearic Islands’ power grid. By combining this technology with the 3.34 MWp photovoltaic power plant, Endesa is promoting energy management efficiency, helping to meet renewable generation needs and grid requirements. This initiative is helping to reduce dependence on fossil fuels, accelerating the islands’ transition to energy self-sufficiency.

The implementation of the project at Son Orlandis is accompanied by community involvement. Endesa, through its subsidiary Enel Green Power España, has launched training initiatives aimed at improving local employability in the renewable energy sector. Collaborations with foundations such as Juan XXIII and Esment have promoted social integration and improved economic and social conditions for the local community. These efforts are aimed at integrating the project into the island’s social and economic fabric.
