GravyX strengthens Solaria’s position in the European energy storage market.
First wind PPA signed with Repsol
Solaria announced its first 10-year wind PPA for 180 MW, supported by its hybrid plants in Garoña and Armus, and a 10-year solar PPA for 150 MW from its Catalonia plant. Both agreements will supply renewable energy to Repsol’s hydrogen stations, consolidating Solaria’s entry into the green hydrogen market.
European data center platform launched
Solaria unveiled a large-scale European sustainable data center platform with 3.4 GW of secured capacity, an additional 5 GW under application and 400 hectares of land acquired or under negotiation.
The first agreement, signed with Merlin, includes a 225 MW data center ensuring grid access and required electrical infrastructure, marking a new step in integrating generation and digitalization. Solaria also signed a 15-year solar PPA with Merlin for 445 MW.
International growth: Germany, Portugal and Italy
Construction of two PV plants totaling 200 MW will begin in Germany in Q1 2026. Portugal will host Solaria’s flagship hybrid project, combining 474 MW of solar, 154 MW of wind and 130 MW of BESS across two sites: Casal Da Valeira / Vale Pequeño and Vale Da Pedra.
In Italy, Solaria has secured environmental approvals (EIA) for 1 GW of new solar projects:
• 600 MW in Spinazzola, hybridized with 140 MW of BESS and a 400 MW data center;
• 150 MW in Garaguso (already approved), with a 150 MW data center;
• 110 MW in Palermo, with a 100 MW data center.
José Arturo Díaz-Tejeiro Larrañaga, CEO of Solaria, stated:
