Grenergy Secures US$355 million Financing to Propel Central Oasis Solar-Plus-Storage Platform in Chile

Grenergy has closed a US$355 million senior non-recourse financing agreement for Gran Teno, Tamango, and Planchón plants, which together contribute 398 MW of solar capacity and 1.4 GWh of storage to the Central Oasis platform in Chile.

The funding was arranged through an international banking syndicate coordinated by BNP Paribas, alongside Banco Santander and Rabobank. The proceeds will enable Grenergy to refinance its existing solar assets and add battery storage to the operational Gran Teno (241 MW solar, 884 MWh storage) and Tamango (49 MW solar, 158 MWh storage) plants, while also financing the construction of the new Planchón hybrid facility (108 MW solar, 379 MWh storage). All three projects form part of Central Oasis, one of the company’s battery storage platforms in Chile. 

The three assets are backed by long-term solar power purchase agreements (PPAs), ensuring stable revenue streams, while any surplus generation will be commercialized via GR Power, Grenergy’s energy trading subsidiary in Chile. Following this deal, Grenergy’s total secured non-recourse financing for its Oasis platforms nears $1.6 billion, covering both Oasis de Atacama in northern Chile and Central Oasis in the Maule and Biobío regions.

Designed to deliver 1.1 GW of solar capacity alongside 4 GWh of battery storage, the Central Oasis platform entails an estimated investment of around US$900 million and is scheduled to enter into operation across 2026 and 2027. The initiative was developed to mirror the proven hybrid solar-plus-storage model that Grenergy first implemented at Oasis de Atacama—recognized as one of the largest battery platforms globally and the first project of its kind in Latin America.
