Renewable energy in Chile: how much electricity the sun and wind generate

Renewable energy in Chile had a record year. According to the National Electric Coordinator (Coordinador Eléctrico Nacional), the body that runs the power grid, solar and wind supplied about 38% of all electricity injected into the system in 2025, the highest share on record. Adding hydropower and other clean sources, two-thirds of the country's electricity is now renewable.

How much electricity renewable energy in Chile generates

The 2025 record was not even throughout the day. At some hours, sun and wind supplied up to 79% of demand, according to the Coordinator. At night, however, the system still relies on other sources.

That contrast explains another figure from the year: hydropower fell 23.0% due to drought, and to fill the gap, coal (+14.5%) and natural gas (+6.5%) generation rose. The progress of renewable energy in Chile therefore depends on two things: how much water is in the reservoirs and how much solar energy can be stored for the night.

Coal	+14.5%
Natural gas	+6.5%

The battery boom

The big news of 2025 was storage. According to the Coordinator:

• By November, 3,182 MW of new plants had joined the system, the largest addition since 2021, and many were storage systems.
• About 1,700 MW of batteries are installed, another 600 MW are in testing and around 4,500 MW are under construction for next year.
• Energy stored in batteries totaled about 2 TWh, more than four times all diesel generation in the year.

Batteries make it possible to store midday solar energy and use it in the afternoon and evening, when demand rises.

What's next for renewable energy in Chile

The Coordinator reported that about 700 MW of coal plants leave the system on January 1, 2026, and estimated new transmission projects at about US$120 million. The cost of running the system in 2025 was about US$1.6 billion, similar to 2024.

For companies, sustainability is no longer just about image: more and more businesses measure their own footprint and their suppliers'. If your company wants to organize its environmental data, also see how Chile's REP recycling law works.
