Non-conventional renewables contributed 45% of electricity generation during August, producing 3,256 GWh of the 7,237 GWh generated by the National Electric System. Conventional hydropower delivered 36% and thermal plants 18%. Generation fell 3.4% month-on-month but rose 0.8% year-on-year. Peak hourly demand reached 13,989 MW on August 28, unchanged from July but up 14.8% compared to August 2025.
The battery storage pipeline declared under construction through the commission’s Resolution 475 process represents a significant portion of future flexibility capacity. The 5,149 MW total across 74 projects would exceed current operational battery storage by a substantial margin and is expected to help integrate higher shares of solar generation, particularly in the northern regions where curtailment has constrained output.
Environmental review activity remained robust. Ninety-seven energy projects representing $21,885 million in estimated investment were undergoing environmental qualification assessment as of August, with 80% targeting electricity generation. Eight new projects entered the environmental service during the month, totaling $1,170 million in declared investment, including 245 MW of generation capacity. Eleven projects obtained favorable environmental resolutions in August, valued at $876 million and including 521 MW of generation capacity across eight projects, with two transmission initiatives and one oil and gas development also approved.
