Insights
Aneel’s tariff review sharply raises Copel Distribuição’s allowed revenues.
Copel Distribuição received Aneel approval for its 6th Periodic Tariff Review, with an average tariff effect of 20.51% from June 24, 2026. The net Regulatory Asset Base is set at R$ 19,936.2 million, signaling substantial recognition of recent capex into the grid.
Parcel B components rise meaningfully versus the 5th cycle, notably return on capital increasing from R$ 984.4 million to R$ 2,530.6 million and operating costs from R$ 1,464.2 million to R$ 2,238.3 million. This expands Copel Distribuição’s regulated revenue and remuneration profile.
