2. About Central Hidroeléctrica Los Coroneles

A Brief History

The Central Hidroeléctrica Los Coroneles was built to harness the flow of the San Rafael River (also known locally as the Río Grande) and contribute to Mendoza’s growing demand for clean electricity. While exact construction dates and technical specifications such as height and altitude remain undocumented publicly, the dam has been operational for several decades, playing a quiet but vital role in the province’s power grid.

Why It Matters

Mendoza is renowned for its wine, but it’s also a pioneer in renewable energy within Argentina. Hydroelectric plants like Los Coroneles help diversify the province’s energy mix, reducing reliance on fossil fuels and supporting the sustainability goals of local communities. Visiting the dam offers travelers a tangible connection to these broader environmental efforts—an educational experience that goes beyond typical sightseeing.

The Setting

Located at coordinates -34.599816, -68.528459, the dam sits amid rolling foothills, olive groves, and vineyards that characterize the San Rafael valley. The surrounding landscape is a patchwork of cultivated fields and native shrubland, creating a picturesque backdrop that changes with the seasons. The water’s surface often mirrors the sky, providing perfect conditions for sunrise and sunset photography.
