The decision is not between a public company and “the market.” It is a comparison between two electricity supply arrangements, their contracts, the way they allocate risk, and their ability to support the operation.
The phrase “Wholesale Electricity Market vs. CFE” reflects a common search, but a technically sound assessment should compare Basic Supply with Qualified Supply. That distinction prevents decisions based on three misconceptions: that the physical service changes, that savings are guaranteed, or that all market contracts are equivalent.
Mexico’s Electricity Sector Law defines Basic Supply as electricity supply subject to tariff regulation and Qualified Supply as competitive supply provided to Qualified Users. The law also establishes that Qualified Suppliers may offer their services under conditions of open competition.
Before comparing, identify what both arrangements have in common
Changing suppliers does not create a parallel electric grid. Continuity and power quality depend on multiple factors within the system and the customer’s internal installation; they cannot be attributed exclusively to the commercial supplier. What does change is the contractual relationship, the way the electricity purchase is structured, and the level of management required.
Comparison matrix: what actually changes
| Variable | Basic Supply | Qualified Supply |
|---|---|---|
| Eligibility | Available to customers that are not registered as Qualified Users or that are legally able to remain under Basic Supply. | Requires Qualified User status for the relevant Load Centers. The National Energy Commission’s current guidance identifies a demand threshold of at least 1 MW for inclusion in the registry. |
| Price formation | Final tariffs are subject to regulation and the applicable methodologies. | Negotiated commercial terms, including price, indexation, hedges, charges, consumption bands, and other components defined in the contract. |
| Choice of supplier | Basic Supply is provided by the State Public Enterprise through the corresponding supply entity. | The user may compare authorized Qualified Suppliers, including CFE Calificados and private providers. Competition among offers |
| Contract term | A standardized service relationship governed by the applicable service conditions. | May involve multiyear commitments, guarantees, contracted volumes, consumption bands, start dates, and termination conditions. |
| Risk management | The company primarily manages its consumption and budget against the applicable regulated tariff. | The company must assess market exposure, hedging, indexation, imbalances, guarantees, and counterparty risk. |
| Information and metering | Management may focus on bills, demand, and the consumption information available through the service. | Usually requires greater discipline in metering, forecasting, reconciliation, and Load Center monitoring. |
| Clean energy and environmental instruments | Depends on the structure of the supply arrangement and the mechanisms applicable to that service. | May incorporate generation portfolios, Clean Energy Certificates, I-RECs, or other environmental strategies, provided they are correctly contracted and substantiated. |
| Internal complexity | Lower contractual and administrative burden for the customer. | Greater involvement from finance, legal, operations, procurement, and sustainability teams before and throughout the contract term. |
| Optimization potential | May be sufficient when electricity does not justify an additional commercial structure or no verified opportunity exists. | May create opportunities for lower total cost, greater budget certainty, and customization, but the outcome depends on the consumption profile and the contract. |
A Qualified Supply proposal must be normalized against the current situation and include every relevant cost component. Comparing an all-in regulated tariff against an isolated energy component can create apparent “savings” that disappear once charges, guarantees, and adjustments are included.
Three companies can reach three different conclusions
There is no universal winner. Suitability changes with the importance of electricity to the business, the behavior of demand, and the organization’s ability to manage a more complex contract.
Stable, electricity-intensive operation
A plant with high baseload demand, several years of reliable data, and a team capable of validating contracts may find value in hedging, budget certainty, and negotiated terms tailored to its profile.
A detailed Qualified Supply model is warranted.A company in expansion
New production lines, new Load Centers, or uncertain future capacity may make infrastructure, metering, and demand scenarios a higher priority than committing long-term volumes.
The supply decision should be integrated with the growth plan.Volatile consumption or incomplete information
Large fluctuations, unexplained seasonality, or a lack of interval data weaken the baseline. A sophisticated contract does not compensate for poor information and may transfer risks that the company cannot yet measure.
Organize the data first; compare contracts second.The correct equation is total cost plus risk
The financial analysis must convert different proposals into comparable scenarios. Adding pesos per megawatt-hour is not enough; the analysis must also assign value to certainty, flexibility, obligations, and the cost of making the wrong decision.
Five clauses may matter more than the initial discount
Decision tree: what should be reviewed first
Optimize before changing supply arrangements
- Correct metering, demand management, and data quality.
- Review efficiency and infrastructure conditions.
- Remain under Basic Supply when the opportunity does not justify the additional complexity.
Build a defensible comparison
- Verify eligibility and the status of every Load Center.
- Model scenarios from a single, consistent baseline.
- Compare suppliers, contract terms, risk, and operational capabilities.

Four myths that distort the comparison
Incorrect. Physical delivery continues through Mexico’s National Electric System and the corresponding network infrastructure. The primary change is commercial, contractual, and operational.
That cannot be determined without data and contract terms. The result depends on the load profile, the components being compared, the contract horizon, and the allocation of risk.
CFE also operates CFE Calificados, an entity authorized as a Qualified Supplier that represents customers in the Wholesale Electricity Market.
A supplier can provide support, information, and process management within its scope, but it does not control all grid infrastructure or eliminate system constraints.
The best option is neither the simplest nor the most sophisticated
It is the option that creates the right balance of cost, certainty, flexibility, and execution capacity for the company’s current stage.
A rigorous assessment may conclude that the company should move to Qualified Supply, remain temporarily under Basic Supply, or first improve metering, efficiency, and infrastructure. All three conclusions can be correct when they are justified by the business.
