According to a study carried out by specialized consultancy Volt Robotics, Between 2022 and 2031, solar DG (distributed generation) will reduce hydrological risk by an average of 24%.
In total, the cost without distributed generation would be R$48,1 billion. Already with photovoltaic technology of R$36,6 billion – totaling a reduction of R$11,5 billion.
In the case of severe droughts, the research indicated that the reduction would be 12%. Without DG, the cost would be R$226,1 billion, while with solar it would be R$199,1 billion – a reduction of R$27 billion.
The survey also presents a projection of a reduction in greenhouse gas emissions, which in average scenarios reaches 67 million tons of CO2 by 2031.
In the scenario of a new water crisis, with greater activation of more expensive and polluting thermoelectric plants, the reduction in greenhouse gases would be 121 million tons of CO2.
In addition to this data, the company indicated that, between 2022 and 2031, GD will reduce thermoelectric production on average by 1.519 MWm (15%). In drought events, the reduction is 2.726 MWm (19%).

Public policies and the future of solar
Another point highlighted by Volt Robotics is the signaling of the role of policies in making these future scenarios viable, without the need for public resources, with a focus on direct and pragmatic actions to be adopted within the scope of the MME (Ministry of Mines and Energy), CNPE (National Energy Policy Council) and ANEEL (National Electric Energy Agency).
“A ABSOLAR and the sector work to ensure that the self-generation of photovoltaic energy is treated in a fair and balanced manner, as determined by Law No. 14.300/2022”, said Rodrigo Sauaia, executive president of ABSOLAR.
Furthermore, he emphasized that the benefits of solar are correctly identified and incorporated into guidelines to be made official by CNPE by means of a resolution to be published this year, from which the ANEEL will perform the calculations for subsequent auditing of the company”, he explained.
In the Association's view, the guidelines are strategic for the future of self-generation of renewable energy in Brazil, fundamental for the country's sustainable development.
“Therefore, it is essential that the rule-defining process be thoroughly reflected upon and compatible with the scope and importance of the topic for Brazilian society,” commented Bárbara Rubim, vice president of distributed generation at ABSOLAR.
Guilherme Susteras, coordinator of the distributed generation working group at ABSOLAR, highlighted that the population and the National Congress are closely following this work.
“The idea is precisely to ensure that renewables receive the correct, appropriate treatment and consistent with Brazil’s needs, in order to maximize the benefits they can provide to all citizens”, he concluded.
