Solar energy has proven to be an efficient and sustainable solution for shielding industries from the impacts of tariff flags. With frequent increases in electricity bills, many companies have been suffering from the instability of Brazil's power matrix, which still relies primarily on hydroelectric plants.
When rainfall volume decreases and reservoir levels in hydroelectric plants drop, energy production declines. To meet demand, the government activates thermal power plants, which use fossil fuels and have much higher operating costs. As a result, the National Electric Energy Agency (ANEEL) activates the red or yellow tariff flag, raising the amount charged on the electricity bill. For example, in April 2024, the yellow flag returned with an additional cost of R$ 1.88 for every 100 kWh consumed (Source: ANEEL).
Although this increase may seem small in residential or small commercial settings, the scenario changes drastically when discussing the consumption of an industrial plant.
The impact of tariff flags on Brazilian industries
Some industries spend over R$ 100,000 per month on electricity. When the red tariff flag goes into effect, this amount can increase by up to R$ 35,000 monthly. This extra expense represents a significant loss, which is often passed on to the end consumer in the prices of products and services.
Beyond financial costs, industries also face unpredictability. Climatic variations, such as prolonged droughts or excessive heat, reduce the volume of water available to turn hydroelectric plant turbines. Consequently, energy generation decreases, costs increase, and corporate financial planning becomes more unstable.
Solar energy as an alternative to tariff flags
In light of this scenario, many industries have decided to migrate, partially or fully, to renewable sources. Photovoltaic solar energy leads this change due to its economic viability and sustainability. By installing solar systems at their facilities, companies significantly reduce their dependence on the electrical grid and, consequently, shield themselves from the impacts of tariff flags.
The main advantage lies in cost predictability. With the initial investment in PV modules and support structure, the company eliminates fluctuations in the electricity bill. After amortizing the system, the generated energy represents net savings, reaching a reduction of up to 95% in the monthly invoice value.
Real savings and guaranteed return
The math shows how this choice pays off: in many cases, the amount invested in a solar energy system is equal to or less than the annual cost of just the additional tariffs imposed by tariff flags. The difference is that, unlike the tariff, the photovoltaic system represents an asset that increases property value, requires little maintenance, and generates clean energy for over 25 years.
Companies in various sectors, such as metals, textiles, food, and plastics industries, already use solar energy to supply part or all of their operations. Even in large structures, it is possible to size efficient solar systems capable of meeting most of the industrial plant's energy demand.
Is it possible to completely eliminate the effects of tariff flags?
Yes. With a properly sized and homologated photovoltaic system with the energy distributor, the company can generate surpluses during the day and compensate them at night. This process is regulated by the Distributed Generation Legal Framework (Law No. 14.300/2022), which guarantees the right to energy credit compensation for up to 60 months.
In addition, the use of solar energy helps reduce pressure on the national electrical system, decreasing the need to activate thermal power plants. Consequently, it contributes to reducing CO₂ emissions and combating global warming.
Solar energy is accessible for any industry size
The idea that solar energy only serves small properties is in the past. Currently, with specific financing lines for renewable energy, such as Pronampe Verde and BNDES programs, companies of all sizes can install their own solar systems without compromising cash flow.
Installation, maintenance, and monitoring of systems have become simple, safe, and reliable. Specialized companies offer personalized consulting, ensuring that the project meets the specific needs of the industry and brings the expected financial return.
Tariff flags no longer need to weigh on the budget
Tariff flags were created to balance energy supply and demand during crisis times. However, for industries, they have become a growing financial burden. Solar energy emerges as the best response to this challenge, offering energy independence, cost predictability, and significant environmental gains.
Therefore, investing in solar energy is not just a way to escape tariff flags—it is a strategic decision that reinforces business competitiveness and sustainability. The future of industry is directly linked to the energy transition, and those who adopt renewable solutions like solar come out ahead.
