The question we hear most often from operations directors in Mexican industry is direct: do I really need to hire an energy consultant? It's a good question because the honest answer isn't always yes. There are conditions where external consulting is the obvious decision, and others where a company can —and should— handle its energy internally.
This guide doesn't sell consulting. It explains when consulting delivers real value, when it doesn't, what a good Wholesale Electricity Market (MEM) consultant looks for, and how to decide whether ROI justifies the cost.
What does an energy consultant do?
An energy consultant is a specialist who reduces an organization's total energy cost by combining technical, regulatory, and market expertise. In Mexico, the role spans four fronts that rarely coexist in a single person inside the client company:
- Technical — audits, efficiency, monitoring, energy KPIs
- Commercial / contractual — market analysis, supplier negotiation, contract structuring
- Regulatory — Grid Code (Código de Red) compliance, CRE filings, CENACE enrollment, ESG and CELs
- Operational — monthly settlement audit, demand management, behavioral optimization
An energy consultant does not sell equipment, is not a broker that simply connects you with a supplier, and is not a solar panel provider. When someone calls themselves an "energy consultant" but their business model is selling a single solution, that is a salesperson in disguise —not a consultant—.
When hiring energy consulting DOES make sense
There are five situations where external consulting typically delivers a multiple of its cost:
1. Your company qualifies for the MEM and hasn't migrated
If your contracted demand is ≥1 MW, the savings available by migrating to the MEM as a Qualified User range from 15% to 30%. The regulatory, technical, and contractual complexity of that transition —CRE documentation, CENACE enrollment, supplier selection, contract structure, financial guarantees— is high. Doing it right once compensates for years of fees. Doing it wrong costs multiples more. To grasp the full dimension, read our Complete Guide to Qualified Users.
2. You are already in the MEM and the results are not what was promised
This is one of the most common situations we see. The company migrated 2-4 years ago expecting savings of 25%, and monthly bills barely reflect 8-12%. Typical causes: contract poorly calibrated for the real load profile, supplier with operational issues, lack of monthly CENACE settlement audit, untreated Grid Code penalties. A contract revalidation and operational cleanup frequently recover another 5-10% without needing to switch suppliers.
3. Your annual electricity cost exceeds MXN 10 million
Below that threshold, fees for specialized consulting may not be justified. Above it, almost always yes —even a 5% improvement releases MXN 500K in recurring annual savings—. For companies with annual electricity cost of MXN 25M, 50M, or 100M, consulting pays for itself in the first quarter.
4. You are required to deliver ESG / Scope 2 reports with specific metrics
If your global parent or your global customers (automotive, electronics, food and beverage) are asking for Scope 2 emissions reports, RECs, CELs, or clean-generation percentage in your mix, properly structuring those components in your electricity contract requires expertise. The difference between a poorly structured "green" contract and a well-structured one is the difference between actually delivering the report and merely claiming compliance.
5. Your internal team lacks bandwidth and energy specialization
Many Mexican industries are excellent at their core operation but don't have a dedicated energy department. Energy is handled by the plant director or the maintenance lead "as one more bill among many." In that configuration, MEM complexity, CENACE settlements, Grid Code compliance, and demand optimization remain structurally unattended.
When hiring energy consulting does NOT make sense
For professional honesty, there are situations where the answer is no:
- Annual electricity cost below MXN 5 million without growth prospects. Fees and operational complexity probably don't pay back.
- Contracted demand well below 1 MW (e.g. 200-400 kW) without aggregation possibility. You don't qualify for MEM and the contractual lever is limited to optimizing CFE tariff —something a good in-house engineer with a month of training can handle—.
- Operations with very low load factor (below 30%) without behavioral optimization possibility. CFE tariff structure is relatively efficient for this profile and migrating to MEM may not justify the required financial guarantees.
- You already have a mature in-house energy team with certified engineers, an operating monitoring system, and settlement audit routines. Consulting becomes marginal and only adds value in punctual reviews.
Types of energy consulting in Mexico
Not all consulting is the same. Four clearly distinguishable models:
| Type | What it does | When it applies |
|---|---|---|
| Punctual energy audit | Technical diagnostic, measure identification, payback | Companies wanting a map before investing in efficiency |
| MEM migration consulting | Support through the Qualified User process | Eligible companies that haven't migrated yet |
| Continuous operational consulting | Monthly audit, monitoring, optimization | Companies in MEM or high-consumption that want to maximize savings continuously |
| Integral consulting (Plan 360) | 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. The reason: total savings don't decompose into silos. A technical decision affects the contract; a contractual decision changes operations; ESG reports depend on all three.
How a good consultant differs from a mediocre one
After years working this market, the criteria that best predict performance:
- MEM specialization, not generic energy consulting — the MEM is a complex market with its own regulatory body (LIE, CRE, CENACE), its own price mechanics (LMP, firm/spot products, CELs), and its own set of costly mistakes. A generic "energy savings" consultancy frequently doesn't reach this level.
- Fee model aligned with savings — the best consultants charge a fixed portion (for work done) and a contingent portion tied to verified savings. That eliminates the incentive to recommend investments that don't pay back.
- Verifiable track record — how many companies have migrated, what documented savings are reported, what referenceable clients exist. If nobody speaks for the consultant, there's a reason.
- Multidisciplinary team — industrial energy requires electrical engineers, regulatory lawyers, financial analysts, and commercial consultants. A single person, however talented, doesn't cover all fronts.
- Transparent operational reports — monthly audits with bill numbers, kWh billed vs settled, pesos saved vs baseline, deviation alerts. Without monthly reporting, there is no way to know whether the consultant is adding value.
- Commercial independence — a consultant with no financial relationship to a specific supplier is more reliable than one who receives commissions for steering you to a brand.
The Plan 360 Management method
At Enerlogix we designed Plan 360 Management for Mexican industrial companies seeking integral consulting. Four principles distinguish it:
- Diagnostic before recommendation — we never propose a solution without rigorously measuring your baseline (12 months of billing, hourly load profile, contract status, Grid Code compliance).
- Three levers, not just one — most available savings sit in the combination of technical efficiency + well-structured contract + operational management. Working only one leaves money on the table.
- Full-cycle support — from the decision to migrate to today's invoice audit. We don't sell a project that ends when the contract is signed; we sell a continuous operational capability.
- Monthly reports with hard metrics — every client receives a monthly report with: average energy cost vs baseline, accumulated savings, deviation alerts, optimization recommendations for the next period.
Mistakes we see when choosing an energy consultant
After competing in and observing this market for more than 20 years:
- Hiring the cheapest consultant — the fee difference is marginal vs. the result difference. A consultant 30% more expensive who captures 5% more savings pays 10x that differential.
- Hiring the consultant who promises the fastest — MEM processes (CRE registration, CENACE enrollment, technical transition) have minimum cycle times. Whoever promises 6 weeks for something that requires 4 months is minimizing complexity.
- Hiring the consultant with a pre-existing "agreement" with a supplier — independence is an asset. If your consultant only points you to one supplier, you are not receiving consulting: you are receiving commercial intermediation.
- Not requiring monthly operational reports as part of the contract — without verifiable reporting, savings become anecdotal after a few months.
- Assuming consulting is a one-time engagement — energy is a dynamic market. What's optimal today may stop being so in 12 months due to regulatory changes, spot volatility, or new supplier availability.
Quick diagnostic: 5 questions to know if you need energy consulting
Answer honestly:
- Does your annual electricity cost exceed MXN 10 million?
- Is your contracted demand ≥1 MW or will you reach it in the next 24 months?
- Are you required to deliver ESG reports with specific energy metrics?
- Was your last deep electricity contract review more than 24 months ago?
- Do you see recurring penalties on your bills (power factor, excess demand, Grid Code charges)?
Three or more affirmative answers: specialized energy consulting will probably deliver a multiple of its cost in the first year.
