Brazil Net Metering (Lei 14.300/2022 - Marco Legal da GD)
Administered by Agência Nacional de Energia Elétrica (ANEEL)
About this program
Lei 14.300/2022, enacted on 6 January 2022, established the legal framework for distributed generation (Marco Legal da Geração Distribuída) in Brazil, replacing the previous ANEEL Normative Resolution 482/2012. The law maintains net metering for residential, commercial, and industrial consumers, allowing surplus solar electricity to be credited against consumption. Systems installed before 7 January 2023 are grandfathered with full ICMS, PIS/PASEP, and COFINS exemptions until 2045. Systems installed after this date face a progressive Tarifa Fio B (grid usage fee) that escalates from 15% in 2023 to 27% in 2025, reaching full distribution cost by 2029. Brazil's solar capacity surpassed 55 GW in March 2025.
