Aneel Approves Tariff Hikes for Light (8.59%) and Enel Rio (15.46%) Effective March 15

Overview

• Light’s adjustment averages 8.59%, with increases of 13.46% for high‑tension users and 6.56% for low‑tension consumers, while Enel Rio’s rises average 15.46%, with 19.94% for high tension and 14.23% for low tension.
• Aneel departed from a lower technical proposal by cutting the credits counted in bills, citing the risk that part of the PIS/Cofins amounts may not be recognized by the Receita Federal.
• Relator Gentil Nogueira warned of a potentially severe impact on future bills and urged coordination with the Finance Ministry and the Receita to align credit calculations and avoid later reversals.
• Case records show Light has returned roughly R$ 5.86 billion via tariffs versus R$ 5.26 billion in credits recognized by the Receita, and the company preliminarily projects a possible 2027 jump of up to 37.6% depending on the outcome of the credit dispute.
• Enel’s bid to base restitution on a 12‑month average was rejected in favor of a three‑month reference that trimmed 5.98 percentage points from the index, and a federal deputy filed an action popular challenging the approved increases.
