Click here to follow the g1 RN channel on WhatsApp As of November 2025, consumer protection bodies, such as Procon, the Public Defender's Office and the MPRN, began to register several complaints from holders of photovoltaic generation units. The reports indicated a sudden and exorbitant increase in invoice values, without prior communication about changes in the credit compensation logic. The problem affected hundreds of families and entrepreneurs in Rio Grande do Norte. According to the action, the collective injury involves the unilateral change of the billing system by the distributor. The company started to charge the beneficiary units for the full consumption, ignoring the positive balances of accumulated credits. The process also points to the automatic imposition of undue installments and the charging of taxes and tariffs on compensated energy. The practice disrespects the acquired rights of old producers, who have guaranteed exemption until the year 2045. Before the judicialization, the MPRN opened a civil investigation to investigate the retention of credits and the suspension of monthly compensation. The body held extrajudicial hearings and requested technical opinions. The collective action was articulated after attempts at dialogue with the company were exhausted. In addition to the double refund, the institutions demand the payment of compensation for collective moral damages stipulated at R$46 million. The amount will be donated to the State Fund for the Defense of Diffuse Rights. The authors also presented injunctive requests to prohibit the suspension of electricity supply and prevent the denial of affected users. The document also requires the adaptation of customer service channels. Regarding the seriousness of the situation, the action signed by the prosecutors highlights that “the dispute does not rest on mere logistical mismatches of reading, but on the systemic subversion of a mathematical and normative model created to encourage energy sustainability”.
