Copel (CPLE3) reported that the billed electricity market reached 8,810 GWh in the third quarter of 2026 (3Q26), up 5.8% compared to 3Q25. In the first nine months of 2026 (9M26), the billed volume totaled 27,082 GWh, an increase of 5% versus the 25,802 GWh recorded in 9M25.
According to the company, the billed wire market, which already reflects the deduction of the share of energy offset by Mini and Micro Distributed Generation (MMGD), grew 5.8% in 3Q26, mainly supported by the performance of the residential and commercial segments. Copel attributes the result to higher temperatures, which drove consumption, the expansion of economic and services activity in Paraná, and lower solar irradiation, which reduced MMGD generation and increased demand on the company’s grid.
Breaking it down by customer class in 3Q26, residential consumption was 2,577 GWh, up 8.9% from 3Q25, while the commercial segment reached 1,909 GWh, an increase of 10.5% in the same comparison. The industrial class, in turn, consumed 3,337 GWh, growth of 1.3% versus 3Q25, considering the effect of reclassifying industrial consumer units to the residential and commercial classes.

Energy offset by MMGD reduced the market by 992 GWh in 3Q26 and by 3,262 GWh in 9M26, while energy offset under GD II and III modalities totaled 467 GWh in the quarter and 1,467 GWh year to date.
