ANEEL Consumidor is a free Android app developed by the Brazilian Government that enables users to register complaints about electric companies to the National Electric Energy Agency (ANEEL). With this app, users can monitor responses to their registered complaints, check information on electricity tariffs, consumer rights and duties, verify the evaluation of the electricity company with ANEEL, and make suggestions, compliments, and complaints.

Before registering a complaint with ANEEL, it is recommended to try and resolve the issue with the power company. If the problem persists, users should note down the protocol for their service by the company, which will be requested when filing a complaint with ANEEL. Once registered, ANEEL will analyze the complaint and send it to the energy company for clarification and solution of the problem.

Overall, ANEEL Consumidor is a useful app for those who need to file a complaint against their electric company and want to monitor its resolution. The app's interface is user-friendly, and the information provided is accurate and relevant.
