Brazil Electricity Tariffs — Tarifas de Energia ANEEL

Get Brazilian electricity tariffs (TUSD and TE) by utility, compare tariffs across all utilities, and read the current tariff flag — straight from ANEEL's official open data API (dadosabertos.aneel.gov.br). No scraping, no browser, no proxy: it is a plain HTTP call to a public government API.

Consulte tarifas de energia elétrica (TUSD/TE) por distribuidora, compare tarifas entre distribuidoras e veja a bandeira tarifária vigente, direto da API oficial de dados abertos da ANEEL.

What it does

Three query modes:

• tarifas_distribuidora — current TUSD/TE tariffs for one specific utility (e.g. EDP ES, CPFL PAULISTA, ENEL SP), filtered by subgroup (B1-B4) and tariff modality.
• ranking — compares the full tariff (TUSD+TE) across every utility in Brazil for the same subgroup/modality, cheapest to most expensive.
• bandeira — the tariff flag in force (or for a given month) and the surcharge it adds, in both R$/MWh (ANEEL's original unit) and R$/kWh (the unit on the consumer's bill).

What it does NOT do

• Does not compute your final electricity bill — it excludes ICMS/PIS/COFINS taxes, which vary by state and are not part of this data source.
• Does not cover distributed generation / net metering (SCEE).
• Does not cover discounted tariffs (tarifa social, baixa renda) — always the standard full tariff for the subgroup.
• Does not cover group A (high voltage) in this version — only group B (B1-B4, low voltage).

How to use

Pick a mode and fill the matching filters. No proxy or advanced setup needed — the source is a public API with no IP blocking.

• Mode tarifas_distribuidora: set distribuidora to the exact utility code (see the official list).
• Mode ranking: no distribuidora needed — it compares all of them at once.
• Mode bandeira: optionally set competencia (YYYY-MM); leave blank for the most recent months.

Who uses it

• Energy consultancies & efficiency firms — benchmark tariffs across utilities and regions.
• Industry, retail & logistics — track energy cost per site.
• Fintechs & insurers — feed cost models with official tariff data.
• Solar / distributed generation platforms — compare against the grid tariff.
• Journalists & researchers — official, citable tariff data with the resolution number.

Known limitations

• Covers group B only (low voltage: residential, rural, commercial/industrial, public lighting). Group A (high voltage) is planned for a future version.
• Consumption class is determined by the subgroup (B1=Residential, B2=Rural, B3=not applicable — single tariff, B4=Public lighting). It is not a free choice, because ANEEL does not allow arbitrary combinations.
• B4 (public lighting) uses subclass "B4a" (street lighting) only — B4b exists in the source but is not covered in this version.
• Not every subgroup + modality combination exists (e.g. B4 has no "Branca" modality) — the Actor returns an empty dataset with a clear warning in those cases, not an error.
• ranking uses each utility's canonical line (full tariff, no discount, no SCEE) and only considers utilities whose tariff is still in force today — a merged or inactive utility does not enter the comparison even if it has history in the dataset.
• Utilities that were merged or renamed stop receiving new homologated tariffs under the old code — if a name returns nothing in tarifas_distribuidora, check the current code on ANEEL's portal.
