Os cuts determined by ONS (National Electric System Operator) in large solar and wind power plants were responsible for generating a waste of clean energy of R$ 1 billion in the last two yearsAccording mapping of ABSOLAR (Brazilian Photovoltaic Solar Energy Association).
The cuts made were intended to stabilize the system when it was close to collapse. They began to occur in October 2021, two months after a blackout hits 26 of the 27 Brazilian states.
According to the ONS, the interruption in the energy supply was caused by main cause of failure in wind and solar power plant equipment. O the body has since operated under “more conservative” conditions.
However, for the ABSOLAR os cuts in solar and wind generation raise alarm bells for Brazil's need to strengthen the planning and investments in the infrastructure of the electricity sector, especially in transmission lines and new ways of storing clean, renewable energy, generated in abundance in the country.
In the entity's assessment, It is entirely possible to increase the share of renewable sources in the Brazilian electricity matrix, maintaining reliability, safety and stability, as well as ensuring the technical and economic balance of the expansion and operation of the electrical system.
Rodrigo Sauaia, CEO of the association, states that the greater insertion of solar energy in large plants is essential for the country strengthen its economy and drive the energy transition process. “The solar source is part of this solution and a true driver of generating opportunities, new green jobs and income for citizens,” he said.
The executive also highlighted that the growth of solar energy strengthens sustainability, relieves family budgets and increases competitiveness of the Brazilian productive sectors, factors “increasingly important for the national economy and for fulfilling the environmental commitments assumed internationally by the country”, he pointed out.
Centralized solar energy
According to data from the ABSOLARThe large solar plants add up more 15 GW of operational powerl in Brazil.
Since 2012, the segment has accumulated BRL 64,3 billion in new investments and more than 452,5 thousand green jobs, And R$21,3 billion in revenue for public coffers.
Currently, Large-scale solar plants operate in all Brazilian states, with leadership, in of installed power, from the Northeast region, with 58,6% representation, followed by the Southeast, with 40,3%, South, with 0,5%, North, with 0,3% and Central-West (including the DF), with 0,3%.
“Brazil has one of the best solar resources on the planet, which opens up a huge possibility for the production of the cheapest green hydrogen in the world and the development of new synergistic technologies, such as electrical energy storage and electric vehicles,” explains Ronaldo Koloszuk, Chairman of the Board of Directors of ABSOLAR.

Isolated Systems currently spend R$1 billion/year on thermal power plants, but there has been no SIN in these regions for decades. Wouldn't the thermal power plants be built with government information for a tetary? Mor, because it has been decades, I mean, the money from these SiSols in decades would already pay for a SIN. Police reports have already been reported on this big teat!!
The greatest waste occurs on weekends. There has to be some way to turn off thermal power plants at 8am on Saturday and turn them back on at 18pm on Sunday. Inflexibility cannot apply during this period.
Furthermore, there has to be some way for hydroelectric plants to be able to stop production between 10am and 14pm on Saturday, and between 09am and 15pm on Sunday, considering that the installed capacity of solar and wind power will increase significantly by 2028.
At the same time, a study into the use of batteries at these same times for solar plants to store energy and release it immediately afterwards could be considered by the companies themselves, so that they do not have to throw away their energy.
