CATL will supply the BESS units for Grenergy’s two large-scale energy storage projects in Spain, both of which have decade-long tolls.
The companies announced the deal for Grenergy’s 700MWh Oviedo standalone battery energy storage system (BESS) project and its 680MWh Escuderos solar-plus-storage project last week (21 May), its flagship storage projects in Spain.
Grenergy announced a 10-year toll for the Oviedo project with an unnamed international utility in February this year, and then a 12-toll for Escuderos’ BESS a few months later, also with an unnamed utility offtaker.
