Mexico: New requirements for interconnected self-supply generation permits have been published

In brief

On 6 August 2025, the National Energy Commission (CNE) published in the Official Federal Gazette an Accord that establishes the requirements to obtain a generation permit for interconnected self-consumption in electrical centers with a capacity of between 0.7 and 20 megawatts (MW). (“Accord”). 

Given that the Electricity Sector Law1 (“LSE”) introduced a new type of permitted generation activity known as interconnected self-supply, whose excess energy may be supplied to the National Electrical System (SEN) and sold to the Federal Electricity Commission (“CFE”), the Accord is meant to establish a clear, accessible, and digitalized process for the reception, analysis and resolution of permit applications in this modality, applicable to individuals, legal entities or public entities interested in developing self-consumption projects interconnected to the National Transmission Grid or to the General Distribution Grid.

Key points

1.    Applicability

The Accord is applicable to all individuals, legal entities, or public entities interested in obtaining an electrical generation permit in the modality of interconnected self-supply, whose capacity is equal to, or greater than, 0.7 MW and less than 20 MW, who intend to connect themselves to the National Transmission Grid or the General Distribution Grid.

2.    Formalities for obtaining a self-supply permit

To receive, transmit, attend to, and resolve permit applications for interconnected self-consumptive generation, the CNE must consider the following rules:

  1. Applications must pass through the CNE’s electronic receipt portal or the CNE’s office.
  2. The applicant must present a format approved by the CNE containing the applicant’s corporate and financial information, the technical characteristics of the project, Energy Sector Social Impact authorization and results from studies conducted by the National Center for Energy Control.

3.    Enforcement and additional considerations

The Accord will become effective once the Regulations of the Electrical Sector and Planning and Energy Transition Laws are published and enter into force.

  • Suspension of terms and deadlines: It should be noted that the CNE2 maintains the suspension of the reception, attention, and resolution of new electric energy generation permits, including those regarding interconnected self-supply, unless they relate to priority projects in order to guarantee energy supply in deficient regions in the national territory.3
