The Agência Nacional de Energia Elétrica (ANEEL) is Brazil's federal electricity regulator.

Regulatory Shifts (2026)

• Enforcement Stance: Shifted toward a stricter enforcement posture to filter out speculative players, seen in the caducidade proceeding against Enel São Paulo (news-3215953), the rejection of Âmbar appeals (news-3215980), and restrictions on solar speculators (news-3216007).
• Ex-Ante Framework: Institutionalizing regulatory impact assessments and economic analyses of law via initiatives like the 2º Seminário de Regulação e Análise Econômica do Direito (draft-57). This aims to shield tariff/contract awards (e.g., the R$65B LRCAP 2026 auction) from TCU audits.
• Ex-Post Enforcement: Expanding operational reach beyond Brasília, highlighted by the 3rd National Congress on Inspection in Cuiabá, Mato Grosso (draft-57).
