Limes Renewable Energy has brought its BESS Huañil project to Ready-to-Build status in Chile's Coquimbo region, the developer's first RTB milestone in the country and its first outside Italy.

Located in the municipality of Salamanca, the 200 MW project will store energy from Chile's National Electric System with a capacity of up to 1,000 MWh, enabling a constant injection of 200 MW for up to five hours. Limes estimates total investment at around $188 million.
BESS Huañil is one of three projects Limes has secured environmental approval for in Chile since November 2025, alongside Pradera Larga, an 84 MWp solar plant paired with a 90 MW battery, and the 150 MW BESS Ganso. It is the first of the three to reach RTB, with the other two advancing towards the same stage. The company's broader Chilean pipeline now runs to roughly 180 MWp of solar and 620 MW of storage.
Chile‘s geographical advantage
Chile's solar sector is one of the more interesting stories in global renewables. The Atacama Desert has some of the highest solar irradiance anywhere on Earth, low cloud cover, high altitude and almost no rainfall. That combination has turned northern Chile into a magnet for utility-scale solar, with projects there cheap to build relative to their output.

"Bringing our first Chilean project to Ready-to-Build is a defining moment for us in the region, and one that reflects years of disciplined groundwork. It's the mindset behind everything we develop: high-quality, bankable, grid-ready projects built for the long term, not just permitted on paper." said Martin Libra, Limes' Head of LATAM.
Across Chile and Italy, Limes' fully authorised and RTB pipeline now exceeds 600 MWp. In Italy, the company's home market, it has reached more than 400 MWp across 25 projects, with a further 120 MW across six solar projects on track for authorisation before year-end. (TF)
