Grenergy has commenced construction of the Monte Aguila hybrid solar and battery storage facility in Chile’s Biobío region, the company said this week. The $264 million project, located in El Cabrero, will combine 340 megawatts (MW) of solar generation with 960 megawatt-hours (MWh) of battery storage capacity.
The facility is expected to begin operations in early 2027 and is part of Grenergy’s wider Central Oasis platform, a five-phase development in central Chile that will deliver a total of 1.1 gigawatts (GW) of solar and 3.8 gigawatt-hours (GWh) of storage upon completion.
The groundbreaking ceremony was attended by Chilean government ministers and regional officials, highlighting the project’s role in the country’s ongoing energy transition.
“Monte Aguila is a key step forward in the build-out of Central Oasis and underscores our long-term commitment to Chile’s clean energy goals,” Grenergy said in a statement.
All phases of Central Oasis have secured power purchase agreements (PPAs), including a 15-year baseload contract signed in April with state-owned copper producer Codelco to supply 0.5 terawatt-hours (TWh) of renewable electricity annually on a 24/7 basis.
Grenergy said the Central Oasis initiative builds on its Oasis de Atacama platform in northern Chile, a larger-scale hybrid project combining 2GW of solar with 11GWh of storage and backed by a €2 billion investment. That development is also expected to be completed by 2027.
The company aims to replicate this hybrid model in other markets, including Spain, where it plans to apply the approach to its Escuderos project in Castilla-La Mancha. That facility will feature 200MW of solar generation and 704MWh of battery storage.
Grenergy is also progressing with its Greenbox standalone battery storage strategy in Europe, led by the Oviedo project in Spain, as part of its broader push to expand renewable generation and storage capabilities across key markets.
