Buy power in the MEM on terms your CFO can defend

For users above 1 MW, moving off CFE basic supply to Suministro Calificado can lower energy cost. Whether it actually does depends on the whole cost of service, not the price per MWh. MEP helps you see the difference before you sign, with no supplier, no equipment, and no commission on the other side of the table.

Buying Power in Mexico

409 pages on industrial electricity procurement, PPAs, and the MEM, written for the CFO, the procurement lead, and the plant. Published August 2026, data current to 20 August 2026.

  • Why the generator price is not the plant price, and how to read the six charges that sit between them.
  • An RFP suppliers cannot manipulate, with every offer normalized to the meter before it is compared.
  • The 22-tool buyer toolkit, from mandate to renewal, so the buyer’s position is the controlled version.
Chart from the handbook: Basic Supply counterfactual against Qualified Supply recurring cost over five years for a 24,000 MWh per year composite case, with base and downside post-tax NPV
From the handbook. A composite Qualified Supply migration case where the base case clears the approved hurdle and the downside does not. The book shows how to test a supplier offer against both before signing.

One charge becomes six

Qualified supply is a real opportunity to lower and stabilize energy cost. It is also a multi-year commitment, and getting one cost down while the others climb is a common and expensive outcome. The price per MWh is not the answer.

The stack behind the headline rate

Leaving basic supply unbundles a single CFE charge into energy, capacity and demand credits, TDU and transmission, penalties, power quality, and basis risk. Six components, each with its own behavior.

Evidence to connectCurrent bill breakdown, tariff class, contracted demand

Node alignment can decide it

Whether the injection node aligns with your load node in the same grid system, SIN, BCA, or BCS, can determine whether a PPA works at all. Congestion between injection and load is a genuine risk inside many contracts.

Evidence to connectLoad node, grid system, proposed injection point

Everyone quoting you sells something

Suppliers, brokers, and developers each arrive with a preferred answer and a placement fee behind it. MEP is compensated only by you, so remaining on basic supply is a valid recommendation when the evidence supports it.

What we measure

From total-cost model through filings and first invoice. Every assumption is traceable and documented to withstand review by your finance department, your procurement committee, and external auditors.

Total cost of service

Model the full cost under each option, check node alignment and basis risk, and run a contracting-split analysis with a defined CFE fallback. Weeks 1 to 3.

First lookTariff class, contracted demand, load profile

Supplier shortlisting

Qualified suppliers evaluated on total cost of service rather than headline rate, on identical terms. Weeks 3 to 6.

First lookDecision criteria, bidder list, schedule, approvals

Negotiation through signature

MEP represents you in negotiation with specialized Mexican energy-law counsel, reviews the PPA clause by clause, and coordinates signature with your legal team. Weeks 5 to 9.

First lookTerm sheet, draft PPA, credit and security terms

Filings and switch-over

Usuario Calificado registration with CENACE, interconnection and metering with CFE, and CNE filings, run in parallel and paced by the regulators. MEP then reconciles the first billing cycles against the contract.

First lookRegistration status, metering, first invoices

Who approves what

MEP is compensated only by the client, with no supplier affiliation, placement fee, or referral fee. The recommendation is the same whether you sign a PPA, renegotiate, or stay on basic supply.

Reference engagement18%

achieved on a qualified supply RFP across 45 MW and 9 plants

A battery and automotive components group ran a qualified supply RFP across 45 MW and approximately 305 GWh at 9 plants, with the baseline built from bills and interval data. Two further reference engagements: an advanced materials producer achieved 13% on a PPA review across 3.7 MW and 20.9 GWh at 5 sites, and a multi-site industrial user identified 15% on a savings benchmark across 6 MW and roughly 32 GWh at 3 sites.

Savings across MEP reference engagements range from 13% to 18%, at a typical billing-cycle load factor near 84%. Client names are withheld and verification contacts are available during qualified evaluation. Results vary by facility, and MEP does not guarantee savings. MEP does not sell electricity, equipment, or supplier contracts.

Total cost of service analysis

To begin, MEP needs your tariff classification, contracted demand, and the grid system for each load node. For the full analysis: demand history, load profile or interval data, and any existing contract, PPA, or proposal you want benchmarked, all requested after the first conversation under NDA.

Start with one plant

The useful first step is not another supplier quote. It is a total cost of service analysis of what you pay today and what each option would really cost. Request the assessment and MEP will show you where you actually stand. NDA signed first.

Feedback from operating and procurement teams

Organizations remain confidential. Verification contacts are available during qualified evaluation.

The energy audit recommendations were practical and supported by solid financial and operational rationale, making them easy to evaluate and act upon.

Lori C. Procurement Manager, Global Auto Parts Supplier

The energy study was very well done and delivered real results. The team took the time to understand how our plant actually operates and provided clear, practical recommendations.

Ismael H. Plant Manager, Global Mining Company

The support we received on our Power Purchase Agreement was excellent. The team conducted a detailed and professional review.
