BW ESS, the global energy storage owner-operator, has acquired two utility scale standalone battery energy storage system (BESS) projects in Spain totalling 126 MW/up to 675 MWh from Spanish renewable energy and storage developer, Navacant.
The acquisition expands BW ESS’s presence in the Spanish energy storage market, where the company has been active since 2025. Located in the Valencia region, the projects have a capacity of 99 MW and 27 MW, respectively.
The projects have been in development for around 18 months and are expected to reach Ready-to-Build (RtB) status in 2027, with commercial operations targeted for 2028.
The Spanish energy system needs assets that can respond quickly to changing supply and demand, support the integration of variable power and strengthen operational resilience. With energy storage emerging as a critical infrastructure asset class in Spain, the scale and grid-connection capacity of these projects make them a strong fit with BW ESS’s disciplined value creation approach.
Isaac García Moreno, Executive Director at BW ESS, added: “We are targeting significant growth in our Spanish energy storage platform through a combination of greenfield development and acquisitions of high-quality projects at an advanced stage. This requires partnering with developers who understand local market dynamics and can execute efficiently. Navacant’s track record and the project fundamentals, including their large scale and symmetric grid access rights, align with our strategy of building a diversified, high-performing storage portfolio.”
BW ESS intends to own and operate the assets over the long term. CST Energy, one of Navacant’s partners, will continue to lead the projects through the remaining development phase to the RtB stage, drawing on its local market and technical expertise. Once RtB, BW ESS will lead the delivery of the assets through construction and into their operational phase.
César Izco, Partner at Navacant, commented: “This transaction validates our development approach, combining local market knowledge with rigorous technical execution to create institutional-quality assets. Our continued involvement through the development phase ensures project delivery meets the high standards BW ESS expects.”
