AES Andes (ISIN CL0000001140) is building two renewable energy projects in Chile with combined capacity of 1.3 GW, according to Yahoo Finance on September 23, 2026. The Pampas and Cristales projects represent an investment of more than USD 1.1 billion and are expected to enter commercial operation in 2027.

Two projects add 1.3 GW

The projects are located in Chile's northern Antofagasta region and combine solar generation, wind power and battery energy storage. Pampas includes 229 MW of solar photovoltaic capacity, 128 MW of wind capacity and a 171-MW battery system with five hours of duration, as reported by Yahoo Finance on September 23, 2026.

Cristales adds 288 MW of solar photovoltaic capacity and a 340-MW battery system with four hours of duration. The combined project design gives AES Andes a larger renewable generation platform while adding storage that can shift electricity beyond solar production hours.

Storage is central to the buildout

AES Andes has also developed the Andes Solar Hub in Antofagasta. The hub includes Andes Solar Park IV, completed in October 2025 with 211 MW of solar capacity and a 130-MW battery system, plus Andes Solar III, which began operating in 2026 with 171 MW of solar capacity and a 171-MW battery system, according to POWER on September 23, 2026.

The existing hub represents an investment of more than USD 1.3 billion, while the company said construction is advancing on more than 2,000 MW scheduled to enter commercial operation between 2026 and 2027. That comparison shows the 1.3 GW Pampas and Cristales pipeline is one part of a broader expansion cycle rather than a standalone project.

Chile pipeline drives the investor angle

For AES Andes stock, the central issue is the conversion of renewable capacity into operating assets and cash generation. The 2027 operating target for Pampas and Cristales provides a dated milestone, while the mix of solar, wind and storage reduces reliance on a single generation technology.

Renewable capacity remains the key figure

AES Andes is building 1.3 GW of capacity across Pampas and Cristales in Chile, with an investment of more than USD 1.1 billion and commercial operation expected in 2027.
