Who Can Switch to the Open Energy Market in 2026? A Complete Guide

The liberalization of the electricity sector is progressing rapidly in Brazil, and over the past three years, the so-called “free energy market” has become accessible to companies of all sizes. But in practice, who will be able to make the switch? Is it worth it for everyone? And how can you prepare now so you don’t miss out on opportunities to save money? That’s what we’ll discuss in this guide.
Who will be eligible to switch to the open energy market in 2026?

What is the free energy market, and why is it growing?

Simply put, it is a market in which consumers can choose where to buy their energy and negotiate commercial terms, rather than being limited to their local utility. You are no longer “held hostage” by a single option and now have the power to decide on price, contract term, and type of energy source (such as solar, wind, hydroelectric, and others).

This model has been gaining ground in Brazil because it allows for greater cost predictability, encourages the use of renewable energy sources, and fosters competition among suppliers. For companies, this means transforming energy—one of their main cost items—into a strategic business asset.

Who will be eligible to immigrate in 2026?

In recent years, only large consumers with higher contracted demand were able to switch providers. With the new phase of market liberalization that took place in 2024, a much larger number of companies can now operate in this competitive environment, including small and medium-sized businesses, provided they meet the regulatory requirements set by ANEEL and CCEE. And there’s more: the newly approved legislation establishes two additional phases of free market liberalization over the next 24 months.

Some examples of profiles that are likely to benefit:

• Medium-sized companies seeking budget predictability.

• Retail and wholesale chains, which aggregate consumption across multiple locations.

• Corporate offices, shopping centers, clinics, hotels, and commercial condominiums.

• Service companies with significant energy consumption during business hours.

In other words, if your company’s electricity bill is already seen as a significant expense, there’s a good chance that switching to theopen energy marketwill become a viable option.

How does purchasing energy under this model work in practice?

The most common question is: “Okay, but how does the free energy market work on a day-to-day basis?” Instead of receiving a single all-inclusive bill from the distributor, your company will now have separate contracts: one for use of the grid (still with the distributor) and another for energy supply, signed with a specialized provider.

These contracts specify price, term, consumption flexibility, and, in many cases, the type of energy source. This is where specialized management firms come in; they help analyze consumption history, develop scenarios, and negotiate terms that align with the realities of your business, thereby mitigating risks and capitalizing on favorable pricing opportunities.

Why does working with a specialized management firm make a difference?

Navigating regulations, contracts, and price fluctuations is no easy task. An experienced energy management firm acts as a strategic partner, handling everything from feasibility analysis to the ongoing management of contracts after the transition.

Unique Features and Benefits for Your Company

A reliable partner offers:

• Structured cost management: It’s not just about “paying less,” but about developing a procurement strategy aligned with the company’s financial planning.

• Risk management: protection against price fluctuations through well-designed contracts.

• More sustainable energy: the opportunity to purchase renewable energy and actively align your business with ESG practices.

• Close monitoring: reviewing and translating technical data into clear information for the management team and executive board.

When this approach is personalized, the result is a customized energy plan: you understand the reasoning behind each decision, participate in the choices, and see the direct impact on your business’s competitiveness.

How can we prepare today for the migration in 2026?

Even if your company isn’t ready just yet, there’s plenty to do right now: organize your consumption history, review internal processes, simulate contracting scenarios, and understand the regulatory steps involved.
