Since April 2012 people have been able to generate their own electricity and, without a doubt, the most used source by Brazilians is photovoltaic energy.
When a person installs solar panels in their home, there are two ways to use the energy generated: The first and least common is to accumulate the energy generated in batteries to reuse later, when there is no direct energy from the sun; And the most used, which is to connect the energy from the solar panels to the electricity grid of the local power distributor.
In the second form, the excess electric energy produced by the solar panels is supplied to the distributor's network, injecting clean energy to the other consumers. This surplus generates a credit that is used by the generating customer to use the distributor's energy in periods without sunlight, when the panels do not generate power. Although the installation of this system is still unfeasible for the majority of the Brazilian population, only in 2018 and 2019, there was an expansion of 150% of distributed power generation.
Energy consumption at night is taxed by the distributor, as if the person did not have solar panels. Unfortunately, the value of energy generated from clean and renewable sources is lower than the energy generated by the utility, which often causes much more impact on the environment, as is the case with thermoelectric plants.
One way to encourage the generation of clean energy through solar panels is to not charge these microgenerators for the use of the distribution grid infrastructure, for charges and losses of the energy system. These fees are usually charged by other users. These rules are established through the Normative Resolution 482, of April 17, 2012, created by Aneel (National Electric Energy Agency).
"Uncharged fees for solar power generators are offset by saving on the use of other sources of electricity that are scarce and polluting, injecting clean energy into the grid, reducing losses in the electricity system, generating employment and income, among other benefits" – ABSOLAR ( Brazilian Association of Photovoltaic Solar Energy)
Despite the benefits that solar energy production provides, Aneel has made available to public consultation No. 025/2019, to propose changes to the rules applicable to micro and mini distributed generation. One of these proposals is to remove subsidies from distributed generation, directly affecting consumers who generate their own electricity from clean and renewable sources. Such subsidies are disputed by the distributors, who ensure that the mini and micro generators pass on these costs they should pay to non-generating customers.
In this way, Aneel can make the generation of electricity with photovoltaic solar panels unviable, since the return on average investment would be 26 years, a period that exceeds the useful life of the equipment purchased.
ABSOLAR (Brazilian Association of Photovoltaic Solar Energy) defends the permanence of subsidies, stating that on average, 60% of all energy generated by mini and micro generators is consumed immediately, and 40% is surplus energy that is injected into the grid. ABSOLAR President Rodrigo Sauaia says that "the rate tends to be 60% of what is sent to the distributor."
Aneel together with the Ministry of Economy, claims that the power generation sector no longer needs subsidies, and predicts that by 2030 this amount will reach $ 54 billion, paid by all consumers in Brazil. The new rules, if approved, will come into force in 2020 for new customers, and from 2030 for others.
The public consultation will be open to receive suggestions and contributions until December 30 this year. Those interested in participating should send suggestions via email (email protected) or by correspondence to the Agency's address: SGAN, Quadra 603, Module I, Ground Floor, General Protocol, CEP: 70830-100), in Brasília-DF .
