Chile curtailed a record 2,680 GWh of solar and wind generation in the first seven months of 2026, up 1.6% from a year earlier. The country also had 2,655 MW/11,250 MWh of battery storage in operation by the end of July.
Chile recorded 2,680 GWh of curtailed solar and wind generation in the first seven months of 2026, the highest level recorded for the January-to-July period, according to the July statistical bulletin from the Chilean renewable energy association Acera. The figure represents a 1.6% increase from the same period in 2025.
Acera’s annual comparison shows cumulative curtailment in 2026 running above the levels recorded in previous years as of July. The association said the data is based on the July 31, 2026 Executive Operating Summary published by Chile’s energy regulator Coordinador Eléctrico Nacional and covers curtailed solar PV and wind generation.
The latest figure represents a record for the January-to-July period rather than a full-year record. Renewable energy curtailment totaled 6,084 GWh in 2025, up 7.8% from 2024, according to Acera’s annual figures. The association said that without the curtailment, wind and solar power would have accounted for 49.4% of Chile’s electricity generation in 2025, compared with the 42.4% actually recorded.
