About us

We know energy. We manage the sale.

Cumbres Sur is a Chilean firm specialized in originating, structuring and managing the sale of energy and infrastructure projects to domestic and foreign investors and companies.

We advise on the marketing of solar, wind, storage, PMGD and desalination projects, and of their companies, land and rights, from early-stage development to operating assets.

We combine commercial, financial and legal capabilities and work with a network of electrical engineers, environmental consultants and grid-connection specialists. This allows us to address the technical, regulatory, contractual and economic aspects of each transaction in parallel, and to support our clients throughout the process.
