Solaria and Merlin Properties sign 213MW solar energy deal with 40-year PPA and 10-year BESS PPA for Madrid data center

Solaria Energía has secured a 40-year PPA for 426MW of PV capacity and a 10-year PPA for 600MWh of Battery Energy Storage System (BESS) to supply Merlin Properties in Spain. This hybrid power solution, announced on March 9, 2026, provides Merlin Properties with long-term, stable electricity for its Madrid data center. The 40-year duration for the solar PV PPA offers Merlin Properties exceptional price certainty over a multi-decade horizon for its commercial real estate assets. Integrating 600MWh of BESS directly addresses the intermittency of solar generation, ensuring a more reliable power profile essential for data center uptime requirements. This structure provides Solaria Energía with predictable revenue for a substantial portion of its future capacity, while Merlin Properties locks in firm, green power for its critical infrastructure in Spain. The 213MW solar energy deal capacity underscores the scale of this long-term commitment. Merlin Properties, a leading Spanish real estate company (SOCIMI) focused on prime commercial assets, is securing green power for its Madrid data center, aligning its commercial real estate portfolio with sustainability mandates. This PPA enhances the long-term operational stability and environmental profile of Merlin Properties' holdings in Spain. For Solaria Energía, a Madrid-based IPP targeting 6.2 GW in operation by 2025 and 18 GW by 2030, this 426MW PV PPA directly advances its ambitious capacity build-out. The 40-year PPA term provides a stable revenue stream for Solaria Energía, supporting its aggressive expansion plans across Spain. This transaction, involving a hybrid solar and BESS solution, demonstrates how corporate off-takers in Spain are increasingly prioritizing firm, long-term renewable energy contracts to power critical infrastructure like data centers.
