Aneel Raises Copel Distribution Tariffs by 20.51%

Overview

• Aneel approved the periodic tariff review on June 23, 2026, and the new rates took effect June 24, 2026, producing an average consumer impact of 20.51% for Copel Distribuição customers.
• The increase varies by connection type with a 21.87% rise for high-tension users and a 19.85% rise for low-tension users and affects about 5.3 million customer units in Paraná.
• Aneel identified transmission charges, energy purchase costs, sectoral levies and financial components as the main drivers of the revision.
• Copel says roughly 16% of the tariff impact comes from the CDE subsidy for distributed solar generation, estimates a residential reference of about R$0.76 per kW, and notes that most of a consumer’s bill pays for system costs rather than the distributor’s margin.
• Separately, Aneel raised transmission companies’ allowed revenues by 9.41% for 2026–27 with an estimated 1.1% additional effect on consumer bills and introduced a transitional locational signal that could shift costs and investment incentives across regions.
