In 2024, more than one million Brazilian homes should generate their own power

Have you thought about getting your own electricity at home? This possibility already exists and must be increasingly common in the country.

According to estimates by the National Electric Energy Agency (Aneel), by 2024 about 1.2 million households in Brazil will rely on energy produced by distributed generation system, which allows the consumer to install small generators of renewable sources such as solar panels and wind micro turbines, and exchange energy with the local distributor, in order to reduce the value of the electricity bill.

On March 1st, they began to enforce the new rules approved by Aneel for the distributed generation in the country, which should increase demand by the system. One new feature is the possibility of shared generation, ie, a group of people can join in a consortium or cooperative, install a micro or distributed mini generation and use the energy generated to reduce the bills of the consortium members or cooperatives.

According to the Director of Aneel, Mr.Tiago Correia, this change will enable more people to adopt the shared generation. “As large is the system, cheaper is the total installation, because some costs are diluted. This makes the return on investment much faster, and easier the access to the cooperative credit”, he adds.

It has also been authorized by Aneel to the consumer generates energy in a different place of consumption. For example, energy can be generated in a country house and consumed in an apartment in the city, since the properties are in the service area of the same distributor. The standard also allows the installation of distributed generation in condominiums. In this case, the generated energy can be distributed among the investors in percentages defined by the consumers themselves.

When the amount of energy generated in a particular month is greater than the energy consumed, the customer gets credits that can be used to reduce the invoice of the following month. According to the new rules, the period of validity of claims increased from 36 to 60 months.

Between 2014 and 2016, the adhesions to generation model distributed in the country quadrupled, from 424 connections to 1,930 connections. For this year, growth may be up to 800%, according to Aneel. “The growth potential is very large, and the rate of growth has been exponential, because the base is still low,” said Correia. Currently, about 90% of generation distributed in the country corresponds to solar panels.

For the CEO of Solar Photovoltaic Energy Brazilian Association (Absolar), Rodrigo Sauaia, the new rules approved by Aneel will help promote the use of distributed generation in the country. “The review of standards will enable significant expansion of participation of the population in distributed generation. Brazil has just situated itself as an international reference in the area’s forefront, to encourage the use of energy distributed generation, in particular solar generation”, he recalls.

The investment in a power generation system distributed is still high in Brazil, because of the cost of equipment. Rafael Coelho, responsible for distributed generation area of Prátil Company, estimates that a residence can get the return on investment from four years depending on the radiation of the site and the cost of the fare. For him, the investment is worth it, especially because the consumer avoids fluctuations in power tariff.

“When you make the investment in such a system, is the equivalent of you buy an early power block, a stock of energy, which you can use for 25 years without worrying about whether the energy value will go up or go down,” says Coelho. According to him, the increased demand for equipment will make the installation cost reduced in the coming years.
