Overview
- Aneel’s technical teams formally proposed the ‘Tarifa Hora Certa’ on Monday, lowering the automatic‑enrollment threshold to 500 kWh per month and estimating the rule would cover about 5.7 million low‑voltage units.
- The plan would roll out in three stages with calendar dates set for April 2028, April 2029 and April 2031 so higher consumers enter first and smaller ones later.
- Before any consumer is charged under the new regime, distributors must notify customers and send at least three billing cycles of informative, non‑charging statements; customers may opt out into a temporary, higher flat tariff for up to two years.
- Certain groups are exempt from automatic enrollment, including beneficiaries of social tariffs, public lighting and prepaid meters, while units with solar or other small generation and new commercial EV chargers face a 90‑day rule after publication that can make enrollment mandatory.
- Aneel argues the change responds to a generation shift—more daytime wind and solar and costlier night thermal plants—so hourly prices will signal when to shift consumption and could raise or lower bills depending on users’ timing.
