Synopsis

Solaria Energia y Medio Ambiente has signed a 15-year PPA with Merlin Properties to supply 445 MWp of solar power to Merlin's expanding data-centre portfolio in Spain. The deal supports Merlin's low-carbon energy goals while strengthening Solaria's position in the data-centre market. Solaria's extensive infrastructure-spanning solar plants, substations and distribution lines-allows it to offer fast grid access, a key advantage for energy-intensive data-centre operations. Recent grid-connection approvals have pushed Solaria's committed data-centre demand to over 1 GW. Merlin operates facilities in Spain and Portugal, and the agreement ensures long-term clean energy. The partnership aligns with Solaria's plan to scale its renewables pipeline to 14.3 GW by 2028, including wind and battery storage.

Solaria Energia y Medio Ambiente has entered into a 15?year Power Purchase Agreement (PPA) with Merlin Properties to provide 445?MWp of photovoltaic energy to Merlin's data centre portfolio in Spain. The arrangement marks a strategic move by Solaria to deepen its role in the data?centre sector while aligning with Merlin's sustainability goals.


Under the deal, Solaria will channel solar?generated electricity to Merlin's data-centre operations, ensuring a clean and stable power supply over the long term. By relying on Solaria's renewable generation, Merlin can reduce its carbon footprint and secure reliable energy for its computing infrastructure.

Solaria is well?positioned for this initiative because of its extensive energy and grid infrastructure. The company already owns hundreds of kilometres of distribution lines, dozens of substations, and a significant portfolio of solar plants. This infrastructure allows Solaria to offer data centres rapid grid access, cutting down on years of regulatory and construction delays that ordinarily plague new connections.

In recent months, Solaria has secured several grid?connection approvals: for instance, it obtained rights for 213?MW in Madrid and 225 MW in the Basque Country. Combined with other permits, this brings Solaria's committed demand for data?centre power to more than 1?GW.

On its part, Merlin Properties has a growing data?centre business, with facilities in key Spanish locations like Madrid and Barcelona, as well as sites in Portugal. Through this PPA, Merlin can lock in long-term clean energy, supporting its ambition to run low-carbon and energy-efficient data centres.

This deal also fits into Solaria's broader strategy. The company aims to scale its renewables pipeline significantly: by 2028, it plans to reach 14.3?GW of generating capacity, diversifying not just across solar but also wind and batteries. Moreover, Solaria has recently expanded into energy storage, acquiring 260?MWh of battery capacity to better manage supply and demand.

The PPA with Merlin could generate recurring revenue for Solaria while offering Merlin a predictable, green power supply. Financially, long-term PPAs appeal to both sides: they give Solaria stable offtake for its solar output and provide Merlin certainty over power costs.
