Cegasa Energía has announced plans to expand its production capacity. Starting in February 2026, a new production line at a second site in Vitoria-Gasteiz, Basque Country, will go into operation. According to the company, the new line will have a capacity of 50 MWh per month, or 600 MWh per year. With this move, Cegasa aims to strengthen its position in the market for large-scale battery storage systems.

One of the driving factors behind this expansion is increased demand generated by funding programmes from the Spanish Institute for the Diversification and Saving of Energy (IDAE), which are co-financed by the European Regional Development Fund (ERDF). According to Cegasa Energía, these programmes have served as a catalyst for growth.
Technology partnership with EVE Energy
As part of its expansion, Cegasa Energía has entered into a technology partnership with EVE Energy. According to the company, EVE Energy is the world’s second-largest manufacturer of LFP cells for battery storage systems. The collaboration is intended to enhance supply security and reliability across the value chain, as well as accelerate the market launch of new BESS solutions.

At the same time, Cegasa Energía intends to retain technological and operational control over its products. “This agreement enables us to expand rapidly on a solid foundation, strengthening our role as a European manufacturer of BESS systems while continuing to develop our local technology and production capacity,” emphasises Iñigo Atutxa, CEO of Cegasa Energía.
Further expansion plans and first IDAE project
In light of anticipated market growth, the company is already planning two additional production lines by 2027. The goal is to increase total capacity to 1.8 GWh per year, further consolidating Cegasa Energía’s position as a European provider of energy storage solutions.
In May 2026, the first BESS system realised under the IDAE funding programme with ERDF support will be delivered. The Burriana project in Castellón is being developed in partnership with Corporate Solar Holding and Beavier Photo Power and will offer a storage capacity of 40 MWh. (nhp)
