When an operations director receives a proposal from an "energy consultant," half the time what arrives is actually a quote from someone selling equipment, solar panels, or a contract with a specific supplier. The consultant label has become elastic in the Mexican market, and that explains why so many industrial companies have a lukewarm or disappointing experience with the first consultancy they hire.
A real energy consultant is not a salesperson in disguise, not a broker connecting dots, not a one-off audit technician. They are a specialist who reduces total energy cost by operating levers that rarely coexist in a single person inside the client company. This article explains what the role actually does, what deliverables you should expect, and how to measure month over month whether they are adding real value.
The role in one sentence: reduce total energy cost
The most useful operational definition is this: an energy consultant reduces an organization's total energy cost by combining technical, regulatory, and market expertise. The key word is "total." They don't optimize only the bill, only the equipment, or only the contract. They work the sum of every visible and invisible cost —including penalties, inefficiencies, and unaccounted risk— that affects the peso-per-kWh your operation effectively pays.
That mission conditions everything else: the dimensions they cover, the deliverables they produce, and the KPIs they are measured by.
The 4 dimensions of a consultant
In the Mexican Wholesale Electricity Market (MEM) context, a competent energy consultant covers four fronts simultaneously:
- Technical — energy audits, process efficiency, consumption monitoring, energy KPIs by line or shift, evaluation of efficiency opportunities with measurable payback.
- Commercial / contractual — market analysis, evaluation and negotiation with Qualified Suppliers, contract structure (firm/spot/CELs mix, indexing, exit clauses, guarantees), periodic contract-fit review.
- Regulatory — Grid Code (Código de Red) compliance, registration with the Energy Regulatory Commission (CRE), enrollment with the National Energy Control Center (CENACE), Clean Energy Certificates (CELs), ESG/Scope 2 reporting, alignment with regulatory shifts such as the 2025 Energy Reform.
- Operational — monthly audit of CENACE settlements vs. supplier invoice, contracted vs. actual demand management, power-quality monitoring, deviation alerts, behavioral optimization.
The four dimensions interlock. A technical decision (installing a capacitor bank) affects the contract (changes power factor and removes penalties); a contractual decision (signing with a renewable-mix supplier) affects ESG reporting; a regulatory omission (ignoring a Grid Code requirement) can trigger penalties that destroy operational savings. Whoever covers only one dimension leaves money on the table.
What a consultant does NOT do
For honesty —and because the Mexican market confuses these roles— it's worth drawing the line:
- Does not sell equipment. If the proposal ends in an invoice for capacitor banks, harmonic filters, or SCADA, you are not receiving consulting: you are receiving a hardware sale wrapped in a diagnostic. A genuine consultant recommends equipment from an independent vendor with no commission.
- Is not a supplier broker. If the recurring conclusion of the analysis always points to the same supplier, there is an incentive problem. An independent consultant compares, models, and leaves the decision to the client.
- Is not a solar panel provider. Distributed generation may be part of the recommendation, but it is not the product. When "energy consulting" means "audit ending in a panel sale," the independence of the analysis is compromised.
- Does not promise MEM migration in 6 weeks. MEM processes (CRE registration, CENACE enrollment, technical transition, contract) have minimum cycle times of 3 to 6 months. Whoever promises drastically shorter terms is either minimizing complexity or doesn't understand it.
Difference between 4 consulting models
Not all consulting is the same. It helps to distinguish four models to know what you are buying:
| Model | Scope | When it applies |
|---|---|---|
| Punctual audit | Technical diagnostic, measure identification, estimated payback | Companies that want a map before investing in efficiency |
| Migration consulting | End-to-end Qualified User process support | Eligible companies that have not yet migrated to MEM |
| Continuous operational consulting | Monthly audit, settlement monitoring, deviation alerts | MEM or high-consumption companies that want to maximize savings month over month |
| Integral consulting | Diagnostic + migration + operations + continuous improvement | Companies that want the full cycle under one team |
Integral consulting —the Plan 360 Management model— typically delivers better results than hiring separate pieces, because total savings don't decompose into silos. Technical, contractual, and regulatory decisions are made together.
Typical deliverables you should expect
If you are hiring energy consulting and the contract does not specify the following deliverables, you are probably buying promises and not work:
- Audited baseline. 12 months of billing, hourly load profile, current average peso-per-kWh, recurring penalties, regulatory standing.
- Projected savings model. Quantified scenarios for tariff optimization, MEM migration, supplier change, technical measures, with explicit assumptions.
- Sequenced roadmap. What is done first, what next, with timelines, owners, and dependencies.
- Monthly operational reports. Average cost of the month vs. baseline, accumulated savings, deviation alerts, recommendations for the next period. Without a monthly report there is no way to know whether the consultant is adding value.
- CENACE settlement audit. Comparison between what CENACE settles and what the supplier invoices, with discrepancy detail.
- Grid Code compliance dashboard. Status of power factor, harmonic distortion, phase balance, inspection calendar.
How to measure if your consultant is adding real value
Four hard KPIs any serious consultant accepts being measured against:
- Average cost per kWh month over month vs. baseline. If it falls sustainedly, the consultant is adding value. If it oscillates without trend, there is a problem.
- Accumulated savings vs. fees paid. A competent consultant delivers a multiple of their cost in the first year (typically 3x to 8x).
- Avoided penalties. Charges for excess demand, low power factor, or Grid Code that stopped showing up on the bill.
- Discrepancies caught in settlements. Pesos recovered from CENACE or the supplier due to metering or settlement errors.
If a consultant avoids these metrics or replaces them with narratives ("we made a structural improvement," "we are positioning you for the future"), it's worth asking what they are being paid for.
When to fire your consultant (3 signals)
The three most frequent signals we see in industrial companies that already had previous consulting and want to switch:
- There is no monthly operational report. When you ask what happened this month and the answer is "all good" without numbers, there is no consulting: there is a relationship.
- Recommendations always conclude in a purchase from a specific vendor. A suspicious coincidence that erodes the independence of the analysis.
- After 12 months, average cost per kWh has not fallen vs. baseline. There are exceptions (spiked spot market, plant in major maintenance), but when the trend is flat without a structural reason, the consultant is not adding value.
If you need a second opinion
If you currently have energy consulting and you doubt whether it is adding value, an independent review of your latest invoice, your monthly reports, and your active contract can clarify in a few days whether the cost of the service is justified. At Enerlogix we do this with no commitment as part of the initial diagnostic.
