EdgeMode, Inc., a global energy and AI data center infrastructure company, has announced plans to expand into Spain’s rapidly growing energy storage market through a proposed acquisition of a majority stake in Ibersun Generación, S.L. The company has signed a non-binding agreement to acquire 51% of the Spanish firm’s share capital, which would give EdgeMode majority control and enable the launch of a large-scale Battery Energy Storage System (BESS) platform in the country.
The transaction remains subject to due diligence, after which definitive agreements are expected to be finalized.The proposed joint venture is aimed at addressing one of the most pressing challenges facing Spain’s electricity system—managing the increasing share of solar energy in the national grid. Spain has emerged as one of Europe’s leading solar power markets, with solar generation accounting for a significant portion of electricity production during peak daylight hours.
However, the intermittent nature of solar power has created challenges related to grid stability, electricity pricing, and energy reliability.Battery energy storage systems are increasingly viewed as a critical solution to these issues. By storing excess solar energy generated during the day and releasing it when demand rises or solar production falls, BESS facilities can help stabilize the grid, reduce power price volatility, and improve overall energy security.
The Spanish government has recognized the importance of energy storage and has introduced a range of incentives, grants, and subsidy programs to encourage the deployment of utility-scale battery projects.According to EdgeMode CEO Charlie Faulkner, the timing of the investment aligns closely with Spain’s evolving energy needs.
He noted that large-scale battery storage has become a structural necessity for the country as renewable energy capacity continues to grow. Faulkner also highlighted the availability of government support programs that can help reduce project development costs while improving returns for investors.If completed, the acquisition would immediately add 52 MW of grid-connected battery storage projects to EdgeMode’s development pipeline.
The company expects these projects to reach Ready-to-Build (RTB) status by the end of 2026, positioning them for near-term construction and deployment. In addition to these projects, the transaction includes access to a substantial development pipeline consisting of approximately 1.9 GW of strategically secured land sites.
These sites have been selected due to their proximity to electrical substations, providing potential advantages in securing grid connection rights and participating in future capacity auctions under Spanish energy regulations. Access to grid infrastructure is increasingly becoming a valuable asset in renewable energy development, making these locations particularly attractive for future expansion.
Once the full portfolio is developed, EdgeMode estimates that the projects could collectively provide approximately 2,900 MWh of energy storage capacity. The first battery storage facilities are expected to become operational within the next 18 months, supporting Spain’s efforts to strengthen grid reliability and accommodate higher levels of renewable energy generation.To finance the development of the platform, EdgeMode plans to utilize a capital recycling strategy rather than relying heavily on new equity issuance.
Under this approach, the company intends to reinvest proceeds generated from selective sales and monetization of assets within its existing AI data center portfolio. By redirecting capital from shorter-term transactions into long-term infrastructure assets, the company aims to create a more stable and recurring revenue base while minimizing shareholder dilution.
The company believes battery energy storage projects offer attractive financial returns compared to other infrastructure investments. According to EdgeMode, the estimated capital payback period for the proposed BESS projects is around six years, significantly shorter than the approximately 12-year payback period often associated with large-scale AI data center developments.
This difference makes energy storage an appealing complement to the company’s broader infrastructure strategy.Faulkner described the proposed acquisition as a major milestone for EdgeMode’s growth strategy, noting that the combination of near-term battery storage projects and a large development pipeline provides the company with a strong position in one of Europe’s most important energy storage markets.
He added that the platform is expected to generate a stable and recurring revenue stream while contributing essential infrastructure needed to support Spain’s ongoing renewable energy expansion and digital transformation.
The proposed transaction reflects growing investor interest in energy storage as countries across Europe seek solutions to balance renewable energy generation, improve grid resilience, and meet ambitious decarbonization targets. As solar and wind power continue to expand, battery storage is expected to play an increasingly important role in ensuring reliable and affordable electricity supplies.
