Last week, the Canal Solar published a reporter regarding the opening of a public consultation by ANEEL (National Electric Energy Agency) to discuss the RTP (Periodic Tariff Review) of Copel (Paraná Energy Company).

At the time, based on initial information, the average adjustment presented by the Agency was 19,20% in the tariffs for consumers served by the distributor, responsible for supplying 5,29 million consumer units in 394 of the 399 municipalities in the state.

However, a detailed analysis of the technical note shows that the impacts vary according to the consumption class and voltage level, and may be significantly greater for some groups.

For urban residential consumers (class B1), the average expected readjustment ranges between 19,15% and 19,20%, with slightly lower percentages for rural areas, estimated at 18,85%.

For high-voltage consumers (which include industries, large businesses, and irrigation systems), the proposed average increase is around 19,55%, an initial value. highlighted by ANEEL on its official website.

However, within this group, there are significant variations between the subclasses. For units classified in class A2, which includes large industries served at high voltage, the increase can reach up to 51,21%.

For class A3, which includes consumers such as medium-sized industries, large businesses, and irrigation systems, the readjustment could reach 45,24%, according to the data presented in... technical document.

Technical note from ANEEL shows tariff variation by subgroup in Copel's review.

Periodic tariff review

Unlike annual tariff adjustments, which update rates based on factors such as inflation and unmanageable costs, the RTP (Tariff Adjustment Program) occurs, on average, every five years in the case of Copel.

In this process, the ANEEL It re-evaluates items such as operational costs, network investments, efficiency targets, and the remuneration of the distributor's assets – factors that directly impact the tariff structure and the concessionaire's returns.

    It would be the last straw if residential consumers, responsible for the smaller fraction of energy consumption, had to shoulder the burden of the tariff increase, right? Also, God forbid that the foreigners at GQC Partners start posting growing profits from their new acquisition. All at the expense of the working population, who have to bear all the rising prices while their salaries remain the same. And let the more than 4 laid-off public servants also struggle. All this so that the corrupt governor can post good economic figures in his final year before leaving office to become a senator.
