Limes Renewable Energy Brings 200 MW BESS Huañil Project in Chile to Ready-to-Build Status

Limes Renewable Energy (Limes), a global renewable energy developer focused on solar, wind and battery energy storage systems (BESS), has achieved Ready-to-Build (RTB) status for its 200 MW BESS Huañil project in Chile’s Coquimbo region. The milestone marks the company’s first RTB project in Chile and its first outside Italy, supporting its international expansion strategy.

Located in Salamanca municipality, BESS Huañil will store electricity from Chile’s National Electric System (SEN) and provide up to 1,000 MWh of energy storage capacity. The project is designed to deliver 200 MW of continuous power for up to five hours and represents an estimated investment of approximately US$188 million.

Since November 2025, Limes has secured environmental approvals for three projects in Chile: BESS Huañil (200 MW), Pradera Larga (84 MWp solar PV and 90 MW BESS), and BESS Ganso (150 MW). BESS Huañil is the first to reach RTB status, while the other two projects are progressing towards the same milestone. Limes’ Chilean pipeline currently includes approximately 180 MWp of solar PV and 620 MW of BESS capacity.

Following the RTB milestone, Limes will focus on revenue structuring aligned with project finance requirements, while advancing strategic partnerships and power purchase agreement (PPA) negotiations. The company said the maturing Chilean pipeline will support its plans to increase installed capacity and strengthen its position as a hybrid Independent Power Producer (IPP).

Martin Libra, Head of LATAM at Limes, said the RTB milestone reflects the company’s focus on developing “high-quality, bankable, grid-ready projects” and positions it to advance strategic partnerships in Chile. Cristiano Spillati, Managing Director of Limes, said the achievement reinforces the company’s long-term commitment to Chile and its local-international development model.

Across Chile and Italy, Limes’ fully authorised and RTB pipeline now exceeds 600 MWp. In Italy, its home market, the company has more than 400 MWp across 25 projects, with an additional 120 MW across six solar projects progressing towards authorisation before the end of the year.
