Renewable expansion and operating scale

AES Andes was building 1.3 GW of Chilean renewable projects on September 23, 2026.
The projects represented more than USD 1.1 billion of investment and were expected to enter operation in 2027.
AES Andes said its operating portfolio totaled 5.5 GW across Chile, Colombia and Argentina.

AES Andes (ISIN CL0000001140) was building two Chilean renewable projects with combined capacity of 1.3 GW as of September 23, 2026. The projects represented more than USD 1.1 billion of investment, according to Yahoo Finance, giving the company stock a concrete operating growth angle despite the absence of a current quoted price in this article.

Two projects add 1.3 GW

The Pampas project combines 229 MW of solar power, 128 MW of wind capacity and a 171-MW battery energy storage system with five-hour duration. The Cristales project includes 288 MW of solar power and a 340-MW battery system with four-hour duration, according to Yahoo Finance.

Both projects were expected to enter commercial operation in 2027. The capacity mix matters because it combines generation with storage, allowing solar and wind output to serve demand beyond the production window.

What does the buildout mean?

The investment is part of a larger portfolio shift. AES Andes said on its investor-relations page that it operated 5.5 GW of generation capacity across Chile, Colombia and Argentina and planned to add more than 4.1 GW of wind, solar, hydroelectric and battery capacity between 2019 and 2027.

The comparison is substantial: the two projects covered in the September 23 report add 1.3 GW, while the broader planned additions exceed 4.1 GW. For investors, execution timing is therefore as important as the headline capacity, because commercial operation was scheduled for 2027 rather than the announcement date.

Storage gives the plan flexibility

Andes Solar III had also begun operating earlier in 2026 with 171 MW of solar capacity and a 171-MW battery system with three-hour duration. The same report said Andes Solar Park IV, completed in October 2025, combined 211 MW of solar generation with 130 MW of battery storage.

The figures show how AES Andes is building a portfolio that pairs renewable generation with dispatchable storage. That combination links the 1.3-GW project pipeline to the company's stated plan to expand its operating capacity through 2027.

Capacity remains the central measure

AES Andes had 5.5 GW in operation and more than 4.1 GW of additions planned through 2027, while the Pampas and Cristales projects accounted for 1.3 GW and more than USD 1.1 billion of investment. The dated project update makes capacity delivery and the 2027 operating timetable the clearest measures for tracking the strategy.
