Power generation on Chile's central SIC grid totaled 4.328TWh in November, up 4.3% on the same month last year.
Broken down by generation source, output came from hydro (58.3%), thermo (36.7%), wind (4.1%) and solar (1%) plants, a report from grid operator CDEC-SIC said.
In last year's corresponding month, these sources contributed 48%, 50.6%, 1.4% and 0.01%, respectively.
Renewable energy accounted for 12.7% of generation, up from 8.3%. Among renewable sources, wind and solar showed the biggest increases in generation, producing 177GWh and 43.3GWh, respectively, from 60.4GWh and 0.4GWh.
November included the startup of the 45MW Punta Palmeras wind farm.
Although increased output from hydro and renewables is normally associated with lower average marginal costs, these spiked 29.7% to US$89.90/MWh from US$69.3/MWh at the benchmark Quillota 220 kV substation.
