EdgeMode acquires 51% of Ibersun in Spanish BESS joint venture
EdgeMode, Inc. (OTC: EDGM), a Florida-headquartered energy and AI data centre infrastructure company, has executed a non-binding agreement to acquire 51% of the share capital of Madrid-based Ibersun Generación, S.L. The deal, which remains subject to due diligence before definitive agreements are signed, is intended to launch a large-scale Battery Energy Storage System (BESS) platform in Spain.
The transaction immediately adds 52 MW of grid-connected BESS projects to EdgeMode's near-term development pipeline, with those sites expected to reach Ready-to-Build (RTB) status before the end of 2026. A further 1.9 GW of strategically secured land plots constitutes the longer-term pipeline. EdgeMode says the sites were selected for their proximity to electrical substations and their ability to secure priority grid-connection access — known as prelación under Spanish regulation — positioning the platform for future capacity auction participation.
The deal
Once fully built out, the consolidated portfolio is projected to deliver approximately 2,900 MWh of storage capacity, with the first projects expected to be operational within 18 months. The company estimates an 80% annual recurring EBITDA margin at full build-out and projects a return on capital of roughly six years — which it contrasts favourably with a twelve-year payback it attributes to a typical AI data centre project.
To fund the BESS platform without equity dilution, EdgeMode says it will recycle capital from selective monetisation within its existing AI data centre portfolio, redirecting transactional gains into BESS development equity. Chief executive Charlie Faulkner framed the rationale in terms of grid necessity: "As Europe's leading location for utility-scale solar expansion, Spain's energy landscape faces unique pressures that make large-scale storage vital for developers, grid operators, and consumers alike."
EdgeMode did not disclose the purchase price for the 51% stake, nor confirm the identity or financial backing of any co-investors in the joint venture.
Market context
Spain's grid management challenge is well documented: solar generation accounts for roughly 80% of capacity during peak afternoon hours, according to EdgeMode's release, creating sharp intraday price spikes and occasional localised outages when storage and flexible demand are insufficient. The Spanish government has responded with grants and subsidies for certified BESS developments, and the country has become one of the most actively watched markets in Europe for utility-scale storage investment.
EdgeMode is entering a field that includes large European utilities, specialist infrastructure funds, and a growing cohort of independent power producers all competing for the same grid-connection slots. The prelación system — which grants priority queue positions at substations — has become a key competitive asset, making land selection and early substation reservations as strategically important as the battery technology itself.
Regulatory and standards read-across
Spanish BESS projects operate under the framework established by Royal Decree 960/2020 and subsequent energy storage regulations, with revenues increasingly tied to capacity market auctions administered by Red Eléctrica de España. EU state-aid rules will govern the extent to which Spanish government grants are available to non-domestic entities such as EdgeMode; that eligibility will be a key due diligence question. Separately, any cross-border investment structure will need to satisfy EU foreign-investment screening obligations if non-EU capital is involved.
The non-binding nature of the current agreement is a meaningful qualifier. EdgeMode is an OTC-listed company with a market capitalisation that is small relative to the stated pipeline ambitions; investors will be watching for confirmation of definitive agreements, evidence of development financing, and early RTB milestone delivery as proof-of-concept for the capital-recycling model.
