Legacy self-supply ends. 1,150+ MW migrated at 25.4% average savings.

Legacy autoabasto and cogeneración permits remain valid only to their original expiration. SENER opened a voluntary migration route in June 2026, and it runs on a registration window. MEP assesses eligibility, cost exposure, and the recommended procurement route, with no supplier commissions and no equipment sales.

MEP wrote the handbook on this decision. Buying Power in Mexico, 409 pages, published August 2026.

Part III covers choosing the procurement structure and which risks the buyer should own. Part IV covers running an RFP that suppliers cannot manipulate.

A decision with a deadline

Qualified supply is an enterprise governance decision, and a time-bound route exists for legacy self-supply portfolios. The question is not whether to move but what the portfolio pays under each route, and who inside the company owns that decision.

The permit cannot be renewed

Legacy autoabasto and cogeneración permits remain valid only to their original expiration. There is no renewal. Every holder has a forced decision with a date attached to it.

Evidence to connectPermit type, expiration date, load centers covered

Basic Supply has no competition in it

There are zero competitive supplier RFPs or negotiated PPAs available within Basic Supply. A portfolio that lands back there has no mechanism to price its own power.

Evidence to connectCurrent route, tariff class, delivered cost today

The strongest cases combine three things

Operating scale, enough spend and demand to attract credible supplier competition. Load stability, continuous operation at a high billing-cycle load factor. Portfolio weight, several load centers under one contracting framework.

Evidence to connectCFE bill, interval data, site structure, decision ownership

What the readiness review produces

A defined decision package. The approval package shows the full bridge from baseline spend to gross savings, fees, retained risks, and expected net benefit before the mandate is signed.

Eligibility screen

Preliminary eligibility against operating scale, load stability, and portfolio structure, plus the information gaps that would block a defensible recommendation.

First lookPermit type, contracted demand, site structure

Commercial screen

Tariff structure, load indicators, market route, data gaps, and the likely scope of supplier competition the portfolio can attract.

First lookTariff class, load factor, site count

Gross and net separated

The business case separates gross market savings from client net value, showing baseline spend, gross savings, fees, retained risks, and expected net benefit as distinct lines rather than one number.

Who approves what

No supplier commissions. No equipment sales. One accountable client-side mandate, so remaining on the current route is a valid recommendation when the evidence supports it.

What is the net benefit after fees and retained risk?

Full bridge from baseline spend to expected net benefit

Legal and compliance

What is our position if the legacy permit lapses without a route?

Permit status, migration route, and the fallback if nothing is done

Procurement

Can the portfolio attract credible supplier competition?

Likely competition scope and a normalized RFP structure

Plant and operations

Does the route change onsite responsibilities or continuity?

Site requirements, metering dependencies, and operating handoff

Recent engagements13 to 18%

savings achieved across recent client engagements

A battery and automotive components group achieved 18% on a qualified supply RFP across 45 MW and approximately 305 GWh at 9 plants. An advanced materials producer achieved 13% on a PPA review across 3.7 MW and 20.9 GWh at 5 sites. A multi-site industrial user identified 15% on a savings benchmark across 6 MW and roughly 32 GWh at 3 sites. Each baseline was built from bills and interval data.

Typical billing-cycle load factor across these engagements is near 84%. The 15% figure is identified rather than achieved. Client names are withheld and verification contacts are available during qualified evaluation. Results vary by facility, and MEP does not guarantee savings.
