In conversations about migrating to the Wholesale Electricity Market, two terms get used as if they were synonyms: "qualified user" and "qualified load." They are not, and the difference is not a lawyers' technicality. Confusing them leads companies to believe they registered what they did not register, to size their project wrong, and to hit the 1 MW threshold without understanding why their application is not moving forward.
This article clears up the distinction at the root. The difference between qualified load vs qualified user boils down to this: the qualified user is the legal figure, the holding entity that registers with the authority; the qualified load is the physical consumption center, the load point that meets the threshold and is enabled to buy energy in the MEM. One is the "who," the other the "where." We explain what each one registers, how they relate to the 1 MW threshold, and which to register depending on how your operation is distributed.
What is the difference between a qualified load and a qualified user?
The qualified user is the legal figure holding the registration with the authority: the company, an individual or legal entity, that signs the contract and assumes the market's obligations. The qualified load is the physical consumption center —the load point— that meets the demand threshold and becomes enabled to participate in the MEM. In short: the user is who registers, the load is what gets registered.
The confusion arises because in a simple plant the two figures overlap: one company, one site, one registration. But as soon as there are several plants, or several corporate entities at one property, the distinction is the key to understanding what can be registered and how. This table summarizes the differences.
| Criterion | Qualified user | Qualified load |
|---|---|---|
| What it is | The legal figure holding the registration | The physical consumption center (load point) |
| Nature | The "who": company or person | The "where": facility or RPU |
| What it signs or assumes | Contract, guarantees, Grid Code, market risk | Meets the technical and demand threshold |
| How it is measured | Has no threshold of its own; its load(s) enable it | Contracted demand equal to or greater than 1 MW |
| Relation to the other | Can hold one or several loads | Belongs to a registered qualified user |
| Before the authority | Receives the registration and the permit | Is registered and associated with the user's registration |
The point almost no one sees at first: the 1 MW threshold is not met by the user, it is met by the load. A huge company with five plants, but with no consumption center reaching the megawatt —not even by aggregation—, has no qualified loads to register, and the legal figure is of no use to it. For the general framework, start with what a qualified user is: the 1 MW threshold.
What is a qualified user?
A qualified user is the electricity consumer that holds a current registration with the regulatory authority and is authorized to participate as an end user in the Wholesale Electricity Market. It is the legal figure: the company that signs the contract, assumes the obligations, and bears the risk. It is not a facility or a meter; it is the holder.
What defines a qualified user against the rest of consumers is the set of rights and responsibilities it acquires upon registering:
- Buys energy from a private qualified supplier, instead of receiving it under CFE's regulated tariff.
- Negotiates the price, term, indexation, and clauses of its supply contract.
- Assumes compliance with the Grid Code and other technical obligations.
- Accesses the MEM's products directly: energy, capacity, and Clean Energy Certificates.
- Assumes the associated financial risk: guarantees, exposure to spot prices, take-or-pay clauses.
The registration of this figure was historically handled before the Energy Regulatory Commission (CRE). After the 2025 reform, the National Energy Commission (CNE) replaced the CRE and took over its functions, so today it is the authority that keeps the registry. The system and market operator remains CENACE, which validates the technical conditions of interconnection and metering. The figure has existed since the market opened in 2014 and remains in force despite the recent adjustments.
A detail that matters for the decision: being a qualified user does not require having a single plant. A company can hold the registration and group under it several consumption centers that do qualify. The user is the umbrella; the loads are what hang from it.
What is a qualified load?
A qualified load is the physical consumption center —the load point, identified by its Permanent User Registry or RPU at CFE— that meets the demand threshold and is registered and enabled to participate in the MEM. It is the concrete asset: the plant, the building, the facility with its meter and its interconnection point. When a load is "qualified," what gets validated is that this specific point meets the technical and demand requirements.
For a consumption center to be considered a qualified load, conditions must be met that do not depend on the company, but on the facility itself:
- Demand equal to or greater than 1 MW. It is contracted demand or verified real peak, not monthly consumption in kWh. It is measured by this load center, not by adding up those of the whole company.
- Connection at medium or high voltage to the National Electric System, with a metering point that meets CENACE's requirements. Low-voltage loads are generally not eligible.
- A measurable and predictable load profile, with data from the last twelve months that supports the threshold.
The consequence is direct: a company can have one registered qualified user and, within it, one load that qualifies and another that does not. The 1.3 MW plant is a qualified load; the same owner's 200 kW warehouse is not. Registering the legal figure does not make eligible a site that does not reach the threshold. That is why the first data point we ask for is not the articles of incorporation, but the demand curve of each consumption center. To see why demand weighs and not consumption, review does your company qualify as a qualified user?.
Can I group several qualified loads under a single user?
Yes. A qualified user can hold several qualified loads, and there is a load aggregation mechanism that allows consumption centers to be added to reach the threshold when none gets there on its own. It is the natural way out for companies with several mid-sized plants instead of a single large one. But aggregation has rules, and it is not as simple as adding kilowatts on a spreadsheet.
It pays to separate two scenarios that get confused:
Several loads that already qualify separately. If you have two plants, each above 1 MW, both are qualified loads in their own right and you can administer them under a single user: one holder, one master contract, several associated loads. Here there is no aggregation to reach the threshold, because each site already meets it; there is administrative consolidation.
Several loads that do not qualify on their own. If you have three centers of 400 kW, none reaches the megawatt. Aggregation seeks to add them so that, together, they exceed the threshold and participate in the market. This route requires case-by-case analysis, CENACE technical review, and, depending on the configuration, the involvement of an aggregator. Not all scattered loads are aggregable: location, voltage level, and the feasibility of joint metering all weigh in.
| Scenario | Does each load reach 1 MW? | What applies |
|---|---|---|
| One plant of 1.3 MW | Yes | One qualified load, one user; direct registration |
| Two plants of 1.1 MW | Yes, each one | Two qualified loads under one user; consolidation |
| Three sites of 400 kW | No | Load aggregation; requires analysis and CENACE review |
| One building of 600 kW | No | Does not qualify alone; assess growth or future aggregation |
Distinguishing between consolidating loads that already qualify and aggregating loads that do not is precisely where many companies go wrong when planning. Assuming that "across all my plants I add up to more than 1 MW, so I qualify" ignores that aggregation is a technical procedure, not an arithmetic sum. And it adds costs that are not always visible at the outset: we develop this in hidden costs of participating in the MEM.
Which figure should I register and how do they relate to the 1 MW threshold?
You don't choose between one or the other: you register the qualified user as the holder and, associated with it, the qualified loads that meet the threshold. The right question is not "which figure," but "how many and which of my loads qualify, and under which holder do I register them." The 1 MW threshold is the filter that decides which loads enter; the user is the legal wrapper that contains them.
The practical way to think about it is from the bottom up, starting with the consumption centers:
- Measure the real demand of each consumption center over the last twelve months. The threshold applies to the verified peak, not to the nominal value of the contract with CFE.
- Identify which loads cross the megawatt on their own. Those are direct qualified loads.
- Assess whether the loads that fall short are aggregable. If they are, aggregation can add them; if not, they stay out for now.
- Define the holder. Determine which corporate entity will be the qualified user that brings together the eligible loads. In groups with several companies, this decision has contract and guarantee implications.
- Register the user and enroll its loads before the authority, with CENACE's technical validation.
The most common costly mistake is reversing the order: starting with "I want to be a qualified user" without confirming there is at least one load that qualifies. The legal figure without an eligible load is an empty shell. The 1 MW threshold lives in the load, and that is why every serious evaluation starts at the meter, not in the boardroom. To place this in the market picture, review the MEM explained for non-experts, and for the procedure, qualified user registration with the CRE.
How Enerlogix guides you
At Enerlogix we don't sell you energy or push you to register so we can charge you for a procedure. We are independent advisors: we measure first and decide with numbers. For this decision, that means characterizing the demand of each consumption center, identifying which are real qualified loads, assessing whether the sites that fall short of the threshold are aggregable, and defining under which holder it pays to register them. If only one of your plants qualifies, we tell you plainly; if aggregation opens a route, we model it with your data before you sign anything.
That work is part of Plan 360 Management: measure, decide with numbers, and execute only what pays for itself. Getting the registration right from the start —the right user, the correct loads associated— avoids redoing procedures, adjusting contracts halfway through, and discovering too late that a site should never have been included. The difference between a qualified load and a qualified user stops being a technicality when it becomes a well-built registration that is not costly to fix later.
Learn about our service for qualified users or, if you already have clarity on your loads, qualified user registration before the authority. And if you want to know how many of your loads qualify and how to best structure your registration, request a free evaluation. With your bills and your demand curve we confirm it with numbers, not promises.
Frequently asked questions
No. The qualified user is the legal figure, the holding company that registers with the authority and assumes the contract and the obligations. The qualified load is the physical consumption center, the load point that meets the demand threshold and is enabled for the MEM. One is the who and the other is the where.
The load meets it. The 1 MW demand threshold applies to the consumption center, not to the company. A qualified user can have several plants, but only those that reach the megawatt on their own or through aggregation are qualified loads. The legal figure does not qualify a site that does not reach the threshold.
Yes. A qualified user can hold several qualified loads. If each plant already exceeds 1 MW, they are consolidated under one holder. If none reaches it alone, load aggregation exists to add them, but it requires technical analysis and CENACE review; it is not a simple sum of kilowatts.
It is the mechanism that allows several consumption centers that do not reach 1 MW separately to be added so that together they exceed the threshold and can participate in the market. Not all scattered loads are aggregable: location, voltage level, and the feasibility of joint metering all weigh in. It is assessed case by case.
Historically registration was handled before the Energy Regulatory Commission, the CRE. After the 2025 reform, the National Energy Commission, the CNE, took over its functions and keeps the registry. The system and market operator remains CENACE, which validates the technical conditions of interconnection and metering.
