Iberdrola España and Ingeteam advance in the hybridization of solar plants with new storage systems in Burgos, Huelva, and Extremadura

Iberdrola España and Ingeteam continue to invest in renewable energy storage as a key technology for the energy transition and decarbonization. Both companies have collaborated on numerous energy storage projects, both in Spain and abroad. On this occasion, Ingeteam will hybridize the existing photovoltaic plants in Revilla Vallejera (Burgos), Andévalo (Huelva), and Almaraz I&II (Extremadura) through a battery energy storage system (BESS). The company will supply and commission its medium-voltage power electronics, control, and SCADA solutions for each of the plants, which will begin operating in the last quarter of the year.

Each of the projects consists of five medium-voltage stations managing 25 MW / 50 MWh, with a total capacity of 100 MW / 200 MWh. The battery storage system (BESS) will store part of the electricity generated by the photovoltaic solar plants in order to improve the management of renewable electricity, resulting in a hybrid electricity installation. The storage systems supplied by Ingeteam include their own Hybrid Power Plant Controller (H-PPC), coordinated with the photovoltaic plant, combining and limiting the power delivered to the connection point’s access capacity.

These storage systems were recently recognized as Strategic Projects for Economic Recovery and Transformation (PERTE) in their Renewable Energy, Renewable Hydrogen, and Storage (ERHA) division, receiving more than 26 million euros in funding from the Institute for the Diversification and Saving of Energy (IDAE).

It is important to note that Ingeteam has previously collaborated with Iberdrola España on other pioneering renewable energy hybridization projects with storage. These include the first battery system installed at an operational wind farm in Spain, as well as the pilot projects in Puertollano and Campo Arañuelo III. In the field of hydroelectric storage, and also with technology developed by Ingeteam, Iberdrola España has commissioned the Santiago-Sil-Xares (Ourense) and Valdecañas (Cáceres) pumped-storage hydroelectric plants in the past year. The latter is considered one of the largest energy storage batteries in Spain. These infrastructures, known as gigabatteries, are essential to advancing the decarbonization of the energy system and represent the most efficient form of large-scale storage available today.

Another project of particular interest carried out by Iberdrola was the installation of the first wind energy storage battery in Bizkaia, which was commissioned in 2022. Specifically, at the ST of Abadiño, where it evacuates the Oiz wind farm (6 MW). It has a guaranteed storage capacity of 3.5 MWh and was installed with Ingeteam's help.

These collaborations reflect the strong and long-lasting relationship between Iberdrola España and Ingeteam, based on mutual trust and a shared commitment to innovation and sustainability. From the Basque Country, they provide high-quality, competitive technological solutions that not only meet local market needs but are also exported to international projects, actively contributing to global electrification and the transition to a cleaner, more efficient energy model.
