Chile Curtailed a Record 2,680 GWh of Solar and Wind in First Seven Months of 2026
Chile curtailed a record 2,680 GWh of solar and wind generation in the first seven months of 2026, according to pv magazine.
The full-year comparison is larger. Renewable curtailment reached 6,084 GWh in 2025, up 7.8% from the prior year, on annual figures from Acera cited by pv magazine.
That lost output moved the generation mix. Acera said wind and solar would have supplied 49.4% of Chilean electricity in 2025 without curtailment, against the 42.4% actually recorded.
Acera attributes the increase to transmission constraints, electricity demand that is insufficient during periods of high renewable output, and the need for greater flexibility in Chile's national electricity system.
Storage capacity is being added against that backdrop. Chile had 2,655 MW/11,250 MWh of battery energy storage systems in operation at the end of July, pv magazine reported.
Wind and solar produced 3,058 GWh in July, or 38.6% of Chilean electricity generation for the month, according to pv magazine.
