A Rare Signal in the Free Energy Market: When the Bill Starts to Arrive

In just over seven years working in the sector, I have rarely seen the market “speak” so clearly. The case of an industrial consumer that decided not to migrate to the Free Energy Market because the operation would generate losses in the current year even with a 50% discount on network tariffs is not an anecdotal detail. It is an indicator of a regime shift.

The fact that the contract termination notice with the distribution company had already been filed before the approval of Law 15.269/2025 only reinforces the seriousness of the decision: this was not improvisation. It was a reaction to numbers that simply stopped adding up.

I reviewed the calculations presented by the energy trader. The conclusion was straightforward: the loss was real.

This is uncomfortable because it contradicts one of the most widely promoted narratives in the market the idea that migration automatically means immediate savings. It does not.

Migration is both an economic and a legal decision, and when the underlying fundamentals change, the outcome changes as well.

What’s Behind It: “Aggressive” Pricing and the PLD as a Crutch

In practice, part of the market has grown by selling electricity below economically sustainable levels in order to capture clients and gain scale.

The recurring bet was well known: a low PLD (Settlement Price for Differences) for longer than fundamentals would suggest, often treated almost as an informal floor of the system a PLD that was, in practice, artificially stable from a risk-signaling perspective.

When that world changes and it does business models dependent on “miracle pricing” start to lose support.

Suppliers begin to feel pressure:

• the need to repurchase energy to honor positions

• higher collateral requirements

• credit deterioration

• and, in more severe cases, liquidity stress.

On the consumer side, what was sold as savings turns into a balance sheet that no longer closes or worse, a contract that begins to be tested at its limits.

Law 15.269/2025: Why the Future May Be More Expensive

The backdrop of 2026 is a set of simultaneous pressures.

From a regulatory and structural perspective, Law 15.269/2025 is increasingly interpreted by market participants as a milestone for recalibrating subsidies and discounts, particularly those related to network tariffs (TUSD/TUST) and their conditions for new migrations and volumes.

In practical terms, the prevailing interpretation is that the incentive window for new entrants is narrowing, and the market is beginning to price this reality.

Combined with evolving price dynamics, the downstream effect is predictable:

• reduced structural benefits for certain migration strategies

• higher prices in the Free Energy Market (ACL)

• and energy cost inflation potentially exceeding general inflation indicators.

When offers for incentivized energy for 2026 appear at levels significantly above R$ 400/MWh, the economic logic for part of the Group A consumer segment changes entirely.

At this point, it is important to clarify a technical aspect that often gets distorted in public debate.

This is not an argument that incentivized discounts are inherently “wonderful”, nor is it a simplistic defense of subsidy structures such as the Energy Development Account (CDE).

The point is much more straightforward: everything in the energy chain must ultimately be paid for.

Generation, commercialization, and delivery all require:

• CAPEX

• OPEX

• cost of capital

• performance risk

• guarantees

• energy backing

• and commercialization structures.

The bill always reappears somewhere in the system.

And when one component becomes unsustainable, the market adjusts through price, conditions, risk allocation, or collateral requirements.

The Other Side of the Coin: Higher Prices Harden Contracts

When prices rise, they do not only affect spreadsheets they change behavior.

In recent weeks, several market agents have been formally notified of contractual non-compliance in energy purchase agreements.

And it is important to emphasize: many notifications are not limited to payment defaults.

They also involve issues that, during more comfortable market conditions, were often treated as routine administrative matters:

• contract signatures

• financial guarantees

• conditions precedent

• deadlines

• and formal contractual milestones.

In a high-price environment, the seller’s incentives become clear: risk aversion increases, and depending on exposure levels, the seller may face repurchase obligations to fulfill contractual commitments or may be economically motivated to seek repricing.

The practical outcome is that contractual compliance stops being bureaucracy and becomes risk management.

When the market tightens, the contract stops being secondary and becomes the central instrument.

2026 May Separate “Price” from “Structure”

The message I leave is straightforward:

2026 is likely to separate those who are in the Free Energy Market for technical and structural reasons from those who entered purely because of price.

Migration, contract renewal, renegotiation and even self-generation strategies must be treated with the seriousness of a sector where nothing is free and where pricing ultimately returns to economic fundamentals.

If the past few years allowed room for excesses electricity that was too cheap, risks underestimated, PLD treated as certainty the current cycle appears to be doing what the energy sector always does in the end:

re-imposing economic discipline and contractual discipline.

For consumers, that means replacing the question:

“What is the lowest R$/MWh available?”

with a more mature one:

“What supply structure can I actually sustain, with measurable risk, adequate guarantees, and real delivery capability?”
