The distributed generation tariff regime after the Law 14,300 transitions

In an article published by Canal Solar, lawyer Juliana de Oliveira examines the tariff regime for distributed micro and minigeneration after the transitions of Law 14,300/2022. The analysis is documentary, with a cut-off of 14 October 2026, and separates what already follows from the law from what depends on regulatory decision.

The text of the law, on the Planalto website, gives the timetable. Under article 27, units without grandfathered rights pay on compensated energy an increasing share of the distribution cost: 60% from 2026, 75% in 2027, 90% in 2028 and, from 2029, the rule of article 17. That article provides for charging the components not associated with energy, net of the benefits valued under CNPE guidelines and ANEEL calculations.

The effect appears in the cash flow year by year. The savings of a new project shrink in known steps until 2028 and then come to depend on a value that is still regulatory.

Those who structure the investment gain by modelling 2029 as a scenario, not as a certainty. A contract that provides for review at that milestone allocates risk more clearly between generator and consumer.
