Grenergy has closed an agreement with the Chinese company CATL to secure the supply of 1.5 gigawatt-hours (GWh) of storage capacity intended for its flagship projects in Spain, those in Oviedo and Escuderos, as communicated by the company.
The pact includes the delivery of 252 batteries of CATL's Tener S model, which integrates ultra-high density containers based on LFP chemistry, designed to optimize efficiency and extend the lifespan of large-scale energy storage assets.
Of the total, 108 batteries, representing 700 MWh, will go to the Oviedo project, considered the flagship project of Greenbox, the group's standalone battery platform for renewables in Europe, and whose entry into operation is planned for the first half of 2027.
The remaining 144 batteries, totaling 800 MWh, will be installed in Escuderos, where the company will again apply the hybridization model already implemented in its Oasis platforms in Chile.
With this move, both parties deepen their alliance, after having previously signed a strategic agreement for the supply of 1.25 GWh of batteries intended for Gabriela, phase IV of the Oasis de Atacama project in Chile.
Grenergy emphasized that this new operation reinforces Spain's role as one of its key markets for the coming years, where it will simultaneously deploy standalone storage projects and hybridization initiatives, "consolidating its position as a benchmark in the European energy transition."
Grenergy's CEO, David Ruiz de Andrés, declared himself "very proud to have a strategic partner like CATL to drive our flagship energy storage projects in Spain."
"After developing large-scale initiatives in Chile, we want to transfer that knowledge to Europe with assets, both in standalone and hybridization projects, that contribute to a more secure, flexible, clean, and competitive electricity system," he added.
