The approval of Law 15.269/2025 by the government marked one of the most significant steps in the recent history of the Brazilian electricity sector.
Within three years, 92 million consumers—households, businesses, rural producers, and small industries—will be able to choose from whom to buy energy, breaking a decades-long monopoly and opening up a market that is finally competitive, transparent, and driven by consumer interests.
Brazil is, in fact, entering its "energy choice era," and this inaugurates a new type of relationship between the country and its own infrastructure.
A new market design
Until now, only large consumers could negotiate directly with generators and traders. The majority of the population remained dependent on local distributors, without the possibility of negotiating terms or prices.
With Law 15.269 / 2025However, this logic is being broken down: middle-class families, small businesses, rural producers, and small industries are gaining access to the same model that already benefits larger companies.
Industry estimates indicate that around 40% of consumers are expected to migrate to the free market within four years, driven by the search for savings, predictability, and autonomy.
Benefits that go beyond cost reduction.
The economic impact of the measure is significant. A study by hug It projects that the annual savings for Group B consumers could reach R$ 17,8 billion.
This relief in the budgets of families and small businesses tends to generate a virtuous circle: more investment in internal improvements, greater competitiveness, expansion of activities and, on a national scale, the creation of new jobs and increased productivity.
The opening up of the energy sector followed, somewhat belatedly, liberalization processes already seen in sectors such as telecommunications and financial services, and is now entering a phase where digitalization and transparency are becoming structuring norms.
Energy maturity reaches the average consumer.
But the transformation is not just regulatory. It ushers in a new mindset regarding energy consumption. For the first time, small consumers will have to make choices that were previously invisible: comparing suppliers, analyzing products, understanding deadlines, and taking an active stance regarding their own consumption. It is the beginning of an energy maturity that until now was restricted to large companies.
For this to move forward safely, a robust effort in communication and energy education will be essential, in addition to digital platforms that simplify the consumer journey and bring predictability to their decisions.
Two steps, three years: the timeline that is redefining the sector.
The law establishes that access to the free market will occur in two stages: first for industry and commerce, within 24 months; then for other consumers, including households, within 36 months.
The government could still bring these steps forward if it develops a communication plan capable of guiding the population on how to choose their supplier.
International experience shows that the speed of migration depends less on the rule itself and more on how clearly consumers understand its benefits, their rights, and their new responsibilities.
Healthy competition and innovation: the path that opens up.
When there is freedom of choice, there is also an incentive for companies to innovate. Openness should drive new supply models, combinations of energy and efficiency, packages that integrate distributed generation, digital monitoring solutions, and more transparent contracts.
This dynamic has already transformed the industrial market, where more than 90% of the energy consumed is acquired on the free market. Now, these innovations should extend to families and small businesses, accelerating a modernization movement in the sector.
The future of energy is hybrid, digital, and consumer-driven.
The universalization of the free market represents not only a regulatory advancement; it inaugurates a new energy ecosystem. Combining distributed generation technologies, storage, advanced metering, and more flexible offerings, the sector is moving closer to a hybrid, digital, and deeply consumer-centric logic.
This consumer, previously a passive spectator, becomes the protagonist of their own choices. For companies like the Bolt Group, which are involved in structuring this transition, this scenario opens up opportunities to expand solutions, innovate, and contribute to a more competitive, sustainable, and intelligent system.
More than just reducing costs, the opening of the free market marks a cultural shift in Brazil. A new relationship with energy is emerging, one based on autonomy, transparency, and freedom of choice. And this change, after decades, is finally reaching all of us.

An answer
Dear colleagues, it's always good to have alternative choices in any market segment, but consumers need to exercise caution when making them. In the case of the free energy market, although there's no need to invest in equipment, the potential for savings, optimistically speaking, is around 40%. If the consumer can invest in their own energy generation facility, there's no doubt that it's a much better solution, in a broad sense. Conservatively, savings of over 80% are envisioned, with a very good rate of return.
