Summary

Mexico’s 28 Oct 2019 DOF modification to CEL lineamientos changes certificate issuance and acquisition criteria, affecting obligated entities and certificate market supply. Obligated participants must confirm their status, calculate certificate requirements, acquire and retire CELs through the CRE system, and maintain an audit trail. Key risks are under-procurement, registry errors, and contract delivery failures. Firms should update compliance models and procurement contracts to reflect the revised eligibility and supply dynamics.

What’s Required

Entities involved in CEL compliance must:

  • Confirm obligated status: determine whether the entity is a “Participante Obligado” required to acquire CELs under applicable rules and notices.

  • Acquire sufficient CELs: procure and hold the number of certificates required to cover obligated consumption for the relevant compliance period.

  • Operate through the certificate management system: manage accounts, transfers, and retirements in the official certificate registry/system established by CRE administrative provisions.

  • Track eligibility rules: after the 2019 modification, entities must apply the updated criteria for issuance and acquisition, including how legacy plants may qualify for CELs.

Important Deadlines

  • Modification published: 28 October 2019 (DOF) for the agreement modifying CEL lineamientos.

  • Ongoing compliance: certificate acquisition and reconciliation occur on periodic cycles defined in implementing rules and notices.

Current Status

  • The 2019 modification is published and operative as part of the CEL rule set used by regulators and market participants.

Penalties for Non-Compliance

Potential enforcement consequences include:

  • administrative sanctions for non-fulfillment of acquisition requirements,

  • restrictions or consequences tied to market participation and compliance status.

Examples of Known Violations

  • insufficient CEL holdings at reconciliation,

  • registry operational failures (missed transfers, incorrect retirement),

  • contract failures where suppliers do not deliver bundled CELs,

  • inadequate audit trail demonstrating how obligations were calculated.
