Press Releases — Grenergy secures $355 million financing for its Central Oasis platform

• The facility has been arranged with BNP Paribas as coordinating bank, alongside Banco Santander and Rabobank
• The financing will support the development of the hybrid plants Gran Teno, Tamango, and Planchón, which together provide 398 MW of solar capacity and 1.4 GWh of storage, all part of Grenergy’s Central Oasis platform in Chile

Madrid, February 11, 2026. Grenergy has closed a $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 financing has been secured with an international syndicate of banks led by BNP Paribas as coordinating bank, together with Banco Santander and Rabobank.

This transaction will allow Grenergy to refinance its existing solar projects and hybridize Gran Teno (241 MW solar and 884 MWh storage) and Tamango (49 MW solar and 158 MWh storage), both currently in operation, as well as fund the construction of the Planchón hybrid project (108 MW solar and 379 MWh storage). All of these assets are part of Central Oasis, one of Grenergy’s battery platforms in Chile.

The three projects benefit from long-term solar power purchase agreements (PPAs). In addition, any excess energy will be marketed through GR Power, Grenergy’s energy trading subsidiary in Chile.

With this transaction, Grenergy approaches $1.6 billion in non-recourse financing secured for its Oasis platforms: Oasis de Atacama in northern Chile and Central Oasis in the Maule and Bíobío regions.

Central Oasis platform and expansion of the Oasis model

With a planned capacity of 1.1 GW of solar and 4 GWh of storage, Central Oasis platform represents an investment of approximately $900 million and is expected to become operational in 2026 and 2027.

Central Oasis was conceived to replicate the successful solar and storage hybrid model Grenergy pioneered in Oasis de Atacama, one of the world’s largest battery platforms and the first of its kind in Latin America.

The success of Oasis de Atacama and Central Oasis paves the way for a new generation of hybrid projects, which the company intends to develop in other markets, including Spain.

Aligned with its 2025–2027 strategic plan, presented during the latest Capital Markets Day in London, Grenergy is moving forward with deploying the Oasis model at the Escuderos plant in Castilla-La Mancha. This facility aims to become a benchmark in Europe, with an expected capacity of 200 MW solar and 704 MWh of storage.
Grenergy is also moving forward with the development of Greenbox, its stand-alone battery platform in Europe, which is another key pillar of its strategic plan. Oviedo plant (Spain) is Greenbox’s flagship project. Through such initiatives, Grenergy further strengthens its leadership in hybrid renewable energy generation and storage solutions.

“This transaction strengthens the support of international banks for our hybridization model, first initiated at Oasis de Atacama and now extended with Central Oasis. It also confirms our execution capabilities, both in the development and signing of PPAs and in project financing,”

Said David Ruiz de Andrés, CEO of Grenergy.
