We advise auto parts manufacturers with several plants in Mexico on MEM migration, Qualified Supply contracting and plant energy audits. We represent the buyer only and take no commissions from suppliers or equipment vendors.
The monthly bill shows the total. It does not show which line start-up set the peak demand or what each system costs per part produced. The MEP review ties every charge to the operating event that causes it.
Simultaneous start-ups of press lines that set the peak demand for the billing period.
kW · kVA · power factorRobotic cells and resistance welding with intermittent load profiles.
load · operating timeBooths, curing ovens and air handling with high thermal and electrical consumption.
temperature · airflow · fuelInjection machines, mold heating and process cooling.
load · temperatureLeaks, pressure above what the process needs and compressors running unloaded.
pressure · flowFurnaces and thermal processes where scheduling defines the cost in peak hours.
fuel · heat · scheduleEnergy consumption divided by the relevant production variable, for example kWh per stamped part or per painted unit. This metric is the common baseline that aligns plant, finance and procurement.
A plant running two eight-hour shifts, five days a week, produces for 80 of the 168 hours in a week. The meter runs for all 168. MEP measures what your plant consumes in the other 88 hours and turns each load into a measure that finance can rank.
New lines, shifts or programs changed the load. The energy baseline and cost targets still reflect the old plant.
Compressed air, pumping, ventilation, ovens, robots and utilities keep running through breaks, weekends and planned stops, even when volume does not justify the consumption.
Maintenance finds opportunities. Finance needs them on common criteria: investment, annual saving, operating risk and priority.
Hourly consumption and demand, shift schedules, production volume and product mix, planned stops, and the load that remains outside production.

Suppliers compete harder for portfolios with scale and stable load. Auto parts plants running two or three shifts usually meet both conditions. MEP evaluates all of your Load Centers under one contractual and governance framework.
Electricity spend and demand large enough to attract credible competition among suppliers.
Continuous or near-continuous operation, with a high load factor across the billing cycle.
One baseline, one tender and one contract for plants in the Bajío, the north and the center of the country.
Portfolios holding legacy self-supply permits have a defined path to migrate to the Wholesale Electricity Market. With a coordinated plan, first supply arrives 7 to 10 months after the baseline starts. Starting early leaves room to compare offers before the period closes.
Per the SENER guidelines of June 2026.
Standardized service from the basic supplier.
Lower internal administrative load.
No competitive tender among suppliers and no negotiated PPA contracts.
Competitive offers from suppliers and PPA contracts.
The supplier represents the load in the MEM.
The buyer controls exclusions, credit, regulatory change and exit terms.
Recommended model for plant networksRegistration as a Market Participant with CENACE.
Higher systems and governance requirements.
Guarantee, forecasting, settlement and compliance obligations.
The two services can be contracted separately. The baseline we build for the tender also serves to prioritize measures on the plant floor.
For portfolios of two or more plants with continuous operation.
For plants that need to prioritize investment before committing capital.
| Scope | Management use | Output for the decision |
|---|---|---|
| Bill and demand review | Resolve a specific tariff, demand or billing problem. | Preliminary findings and the data needed for the next analysis. |
| Plant energy assessment | Identify and prioritize opportunities before committing capital. | Baseline, systems review and prioritized opportunity register. |
| Detailed energy audit | Support an engineering and investment decision. | Measurements, quantified opportunities, conceptual scope and economic evaluation. |
Each figure states whether the result was achieved or only identified. Client names are shared under a confidentiality agreement.
Results vary by facility. Identified figures are estimates subject to verification and do not constitute verified or guaranteed savings. MEP describes a saving as verified only when measurement and verification under IPMVP exists.
Apply the range of results from MEP reference projects to your annual electricity spend. The confidential review replaces this scenario with your own baseline.
An annual spend of MXN 46.4 M multiplied by a gross market saving of 11.6% equals MXN 5.38 M. A net target of 10.0% equals MXN 4.64 M. MEP always separates the gross value from the net value to the client.
Illustrative scenario. Not an estimate or a guarantee of savings. Results vary by facility and depend on load profile, tariff, market offers and contract terms.
Each stage ends with a deliverable that management approves before moving on. You decide at each point whether to continue.
Baseline, load profile, eligibility and governance.
Month 1Comparable offers, total cost model and preferred supplier.
Months 2 to 4Signed PPA, registrations and confirmed readiness.
Months 4 to 7First supply, settlement audit and savings reporting against the baseline.
From months 7 to 10First supply estimated from month 7. The timeline depends on Load Center documentation and on the authorities' processing times.
May receive referral payments or commissions from the winning supplier or from an equipment brand.
Represents the client exclusively and receives no commissions or referral payments from any participant in the transaction. Executive and technical support in English and Spanish, with one point of contact for energy procurement, regulation and settlements.
| Risk | Control |
|---|---|
| Sensitive plant data | An NDA can be signed before bills, interval data or production information are shared. |
| Production disruption | The site work plan defines access, safety, measurements and operating schedules before any field work. The preliminary review needs no site visit. |
| Vendor bias | MEP receives no commissions on equipment or energy sales and does not act as an installer. |
| Unsupported savings | Every investment case keeps assumptions, dependencies, missing data and measurement requirements visible. |
| Unfavorable contract | Price exclusions, pass-through charges, credit, penalties, regulatory change and exit terms are defined before signature. |
One recent CFE bill per plant or twelve months of monthly consumption, the location of each plant and the type of operation. No site visit and no contact with suppliers at this stage.
Yes, but you can start with indices or aggregated figures. MEP can sign an NDA before you share volumes, schedules or diagrams.
The initial response arrives within one business day. The preliminary assessment covers eligibility, commercial exposure, missing information and the recommended procurement path for your portfolio.
That is the norm in automotive networks. The baseline normalizes each Load Center and defines which plants belong in the tender, which stay on their current scheme and in what order they migrate.
Through fees paid by the client. MEP receives no commissions from suppliers, generators or equipment manufacturers, so the recommendation does not depend on which offer wins.
No. Results depend on your data, operation, engineering, investment and execution. MEP documents every assumption and risk so management can decide before committing capital, and calls a saving verified only after measurement and verification under IPMVP.
Yes. The team works in English and Spanish and prepares deliverables for approval by local management and by corporate.
