ANEEL proposes automatic Hora Certa tariff for 5.7 million units above 500 kWh

ANEEL's technical areas will propose to the Board the automatic enrollment in the white tariff, now called Tarifa Hora Certa, of low voltage units with average consumption of 500 kWh/month or more. That is about 5.7 million units, in three stages: 1,800 kWh in April 2028, 1,000 kWh in April 2029 and 500 kWh in April 2031.

The proposal became broader and slower than the one in Public Consultation No. 46/2025, which targeted 2.5 million units above 1 MWh/month, applied by the end of 2026. The new one brings an informative bill for three cycles and a temporary flat tariff, more expensive than the conventional one, until 2033.

Those already connected gain time to move cold rooms and irrigation out of the peak. Micro and mini generation with a connection request filed 90 days after the rule enters with no option to leave, as do new commercial charging stations. The risk that the load does not shift stays with whoever invests.

It is still a technical proposal. The review for each distributor may assess a cheaper period during the hours of highest solar generation. For self generation, storage and charging, the time of consumption becomes part of the project.
