Análise do impacto da tarifa binômia para consumidores residenciais com microgeração fotovoltaica

Abstract

Faced with the current energy crisis experienced in our country with the lack of rain in some areas, the energy distributors were forced to resort to thermal power plants to complement their energy production; raising the cost of electricity generation, they have been forced to repass this value to the customers through the tariff flags. Concerned about a substantial increase in their electric bill, some consumers were forced to search for alternatives so that their electric bills are not affected. Distributed microgeneration, especially photovoltaic solar energy is a relatively simple alternative and has been widely used by residential, commercial and even industrial consumers. The model known as net metering, used to regulate microgeneration systems in Brazil, allied with the monomial tariff system, can generate a cross subsidy among consumers of the same distributor. This phenomenon has generated discussions around the world, involving the application of a binomial tariff to the microgenerators, in order to cover the fixed costs of the distributors referring to these units. Given the current scenario and the imminent need for a revaluation of the tariff system, the present study will analyze the impact that the implementation of a binomial tariff would bring to residential consumers adept and non-adept to the microgeneration system, compared to the current binomial and time of use tariffs.
