BW ESS, a global energy storage owner-operator, has partnered with Getxo-based developer Ibersun to jointly develop 2.2GW of utility-scale battery energy storage system (BESS) projects in Spain as part of a new joint venture.
Spain is rapidly emerging as one of Europe’s largest energy storage markets, with its National Integrated Energy and Climate Plan aiming for 22.5GW of capacity by 2030. This surge is driven by the growth of solar and wind power and limited interconnections with neighbouring countries, highlighting the need for flexible storage solutions to stabilise the grid and avoid renewable energy curtailment.
The BESS deal targets eight greenfield BESS projects across the country, each designed for four-hour duration. BW ESS and Ibersun will share ownership equally, and all projects are expected to reach Ready-to-Build status within two years. A broad set of revenue strategies is being considered.
Ibersun, headquartered in the Basque Country and founded by seasoned energy professionals in 2019, has a strong background in solar and is now expanding in BESS development, highlighted by this new BESS deal.
Isaac Garcia Moreno, executive director of BW ESS, said, “We are proud to be developing our first projects in Spain with Ibersun, a trusted partner with over 25 years of market experience. We have a common objective to improve Spain’s grid resilience and support the market’s ambitious energy storage growth targets. Recent events have underlined that there’s no time to waste in working towards these goals, and we look forward to applying a wealth of experience drawn from multiple global markets to the Spanish context.”
Javier Arkotxa and Jose Antonio Gutiérrez, directors and founders of Ibersun, added, “It’s essential for us that our work blends seamlessly and respectfully with its surroundings and we are delighted to be partnering with a business who shares these priorities. Spain is one of the largest markets for BESS and our joint venture with a global leader like BW ESS is going to help us in our efforts to continue developing the country’s energy potential.”
