Iberdrola and Ingeteam plan to integrate 100MW/200MWh of battery storage at three of Iberdrola’s solar photovoltaic (PV) plants in Spain, as part of a broader strategy to improve energy efficiency and system flexibility.
The hybridisation projects, located in Revilla Vallejera (Burgos), Andévalo (Huelva), and Almaraz I & II (Extremadura), are scheduled to begin operation in the final quarter of 2025. Each site will include five medium-voltage stations capable of managing 25MW/50MWh of capacity.
Ingeteam will provide the medium-voltage power electronics, control systems, and SCADA (Supervisory Control and Data Acquisition) monitoring systems, enabling integration of the storage infrastructure with existing solar assets.
The projects have secured more than €26 million in public funding from Spain’s Institute for Energy Diversification and Saving (IDAE), having been designated as Strategic Projects for Economic Recovery and Transformation (PERTE).
“This collaboration demonstrates a shared commitment to innovation and sustainability,” Ingeteam said in a statement, adding that its control systems are “designed to optimise the performance of hybrid solar-storage plants.”
Iberdrola and Ingeteam have previously partnered on multiple energy storage and hybrid projects, including Spain’s first operational wind-linked battery at the 6MW Oiz wind farm in Bizkaia, as well as pilot schemes at Puertollano and Campo Aranuelo 3. The companies have also collaborated in the hydropower sector, notably at the Santiago-Sil-Xares and Valdecañas pumped storage facilities.
Solutions for the new hybrid projects are being developed in the Basque Country, with potential application in both domestic and international markets.
