Solar production in Brazil explodes before rules change

In order to compensate for the use of the electricity distribution network wire, the regulatory changes in 2019 cause the consumer to rush to a decentralized production when the consumer produces electricity itself and can provide the region's own concession.

In June 2016, 4.4 thousand consumer units in the country received a loan to inject the system into a larger amount than is consumed. In August this year the number came out from 1.168 to 51.500.



On November 23, there were 63,500 people in the three months with an increase of 23%. In total, almost 90% of the loans are related to the solar photovoltaic belt.

The theme, which is the subject of a broad debate during the National Seminar on National Energy Distributors of National Energy Distributors (Sendi 2018) in Fortaleza, is a concern for energy distributors because it can make the business model impossible in the long run.

Concessionists want regulatory change in the shortest possible time, while the Brazilian Photovoltaic Solar Energy Association (Absolar) wants the opposite.

In the midst of disagreement between representatives, the National Electric Energy Agency (Aneel) pledged a public hearing this year to find a solution.

André Pepitone, general manager of the regulator, says Aneel's function is to reconcile anonymous interests. "Innovation transforms consumer relations with the electricity sector.

Over the next five years, we'll make changes over the last 50 years, "he says, so the challenge is to ensure that regulations follow the pace of conversions.

Or There are 130 new distributed production systems per day, but in the universe of 82 million consumers connected to the country's distributors, there is a decrease of 60,000 oceans in the credit, “he says.

It is natural for Pepitone to have different rules for the development of innovations. "In 2015, Aneel developed the 482 resolution to promote distributed production. We will explore the business model in 2019.

It is necessary to separate the thread from the energy correctly, de he explains. Acak The fact is that with the current tariff model, it will not be possible to live with 82 million consumers using distributed production. This is not practical, "he says.

Ildo Grudtner, secretary of the Electric Energy of the Ministry of Mines and Energy (MME), said the portfolio works with Aneel. "It is necessary to estimate adjustments due to new technologies. The model is based on a one-way flow, production, transmission and distribution. Today, the load is now passive and inactive. The flow is two-way," he says.

Of course, the Grudtner count includes the separation of energy from the distribution wire, the revision of subsidies and the improvement of prices and tariffs. "Future will require advanced measurement technology with two-way communication.

As everything is transforming, the dealership business will undergo major changes, "he says." But we need to foresee the legal regulations before the problems arise. "


Nelson Leite, president of the Brazilian Association of Electrical Distribution Distributors (Abradee), emphasizes that the network's basic and even distributed production depends on it.

. The process is a symbiosis. We are in favor of distributed microzonation because it is amazing for us, but it must be implemented with sustainability, "he notes.

According to him, 18% of the amount that the consumer pays in the tariff is to pay for the distribution. Or The problem should be solved when the problem is still small, “he says.

Leite has warned that the price of photovoltaic panels has fallen considerably in recent years, and the payback period has decreased to allow the regulator to withdraw the subsidy without the need for work.

. You have to find the balance, because if those who don't enter the microgeneration don't stop supporting others. As if at a bar desk, you will pay the first payment, the bill increases for who is staying, "he said.

According to him, the binomial schedule solves the situation because it allocates the use of energy from the wire and the compensation is only in the energy.

The Abradee president stresses that distributors do not die in the short term, because Aneel's program foresees to discuss regulatory changes next year and to be implemented in 2020.

Lar The problem is that many people come to benefit, so they are rushing to resolve the regulatory dilemma. It is necessary to know how long the subsidies of those who have existing rules will last. Until you make a payment to the panel, until you have contracts, or is it a lifetime? Sor He asks.

International examples

Two international models were presented during Sendi 2018. In Itaília, according to Alberto Biancardi, the system had to make changes in measurement for intelligent first-generation equipment. In the next three years, Italy will establish the most modern devices that will allow a new set of parameters.

"The devices must be measured and interacted with the dispensers, and they must inform the regulators," he says. The executive director of the Chilean electricity company, Rodrigo Castillo, explained that since it is shared by everyone, it is necessary to better reflect the actual costs in the tariff crossing.

"The demand for modernizing the system in Chile led to an increase of 1.5% on the electricity bill. However, the tariff effort was too small to allow changes to develop," he concluded.
