Grid Market

In the second quarter of 2025, electricity consumption in Copel Distribuição's grid market fell 0.7% compared to the same period last year. This decline is mainly due to the milder weather observed this year, which reduced demand in the residential and commercial segments. On the other hand, the industrial segment performed better, helping to offset part of this reduction and demonstrating the strength and resilience of the economy in the area served by Copel. The billed grid market, which includes energy offset by Mini and Micro Distributed Generation (MMGD), fell by 2.6% in the second quarter of 2025.
