On October 3, 2025, the new regulations governing Mexico’s energy sector, covering hydrocarbons, electricity, biofuels and energy transition matters were published in the Diario Oficial de la Federación (Official Gazette of the Federation, “DOF”), among them, the new Reglamento de la Ley de Planeación y Transición Energética (Regulations of the Energy Planning and Transition Law (“Regulations”).

The publication is available here: Reglamento de la Ley de Planeación y Transición Energética (Regulations of the Energy Planning and Transition Law)

• Under the new Regulations, the creation of the National Energy Transition Strategy is established as a medium- and long-term planning instrument for the energy sector.

• The Regulation specifically governs binding planning for the energy sector, which is oriented toward the development of strategic areas and projects that ensure, among other objectives, Energy Justice , as well as the regulation of energy transition obligations. Binding planning must be taken into account by SENER and the Comisión Nacional de Energía (National Energy Commission; “CNE”) when granting assignments, contracts, permits, concessions, and authorizations.

• The National Energy Information System will be created to consolidate, record, organize, update, and disseminate all sectoral information to support SENER in exercising binding planning. The system will publish public information and document repositories on an internet platform.

• The National Energy Information System must begin operations no later than 180 business days from October 6, 2025, that is June 22, 2026.

• SENER will likewise have until June 22, 2026 to issue the obligations and requirements for acquiring clean energy certificates applicable for compliance during 2026–2028.

• The following regulations are repealed:

Repealed	Replaced By
Reglamento de la Ley de Transición Energética (Regulations of the Energy Transition Law). (DOF 4/05/2017)	Reglamento de la Ley de Planeación y Transición Energética (Regulations of the Energy Planning and Transition Law)

I. Content of the Regulations

I.1. General Matters.

• Regulatory authority is granted to SENER, the Comisión Nacional para el Uso Eficiente de la Energía (National Commission for the Efficient Use of Energy; “CONUEE”), the Centro Nacional de Control de Energía (National Energy Control Center; “CENACE”), and the Centro Nacional de Control del Gas Natural (National Natural Gas Control Center “CENAGAS”).

• The Regulation governs the organization and operation of the Energy Planning Council, which will be composed of SENER, CONUEE, CENACE, CENAGAS, CNE, Petróleos Mexicanos (“PEMEX”), the Comisión Federal de Electricidad (Federal Electricity Commission; “CFE”), and LitioMX. The Council will issue opinions on binding planning and on the publication or updating of planning instruments for the energy sector.

• The National Energy Information System will be created to consolidate, record, organize, update, and disseminate all sectoral information to support SENER in exercising binding planning. The system will publish public information and document repositories on an internet platform.
  
• Inspection, oversight, and enforcement powers are also granted to CONUEE.

I.2. Binding Planning and Social Considerations.

• The Regulation develops the components of binding planning for the energy sector, which will be issued by SENER through general administrative provisions and is oriented toward the development of strategic areas and projects that ensure, among other objectives: (i) the predominance of CFE, (ii) the promotion of decarbonization, and (iii) adherence to the principle of Energy Justice.

• Binding planning will be implemented through: (A) the general administrative provisions issued by SENER, and (B) the “Planning Instruments”, consisting of: (i) the National Energy Transition Strategy; (ii) the Sectoral Energy Program (“PROSENER”); (iii) the Energy Transition and Sustainable Energy Use Plan (“PLATEASE”); (iv) the Electric Sector Development Plan (“PLADESE”); and (v) the Hydrocarbons Sector Development Plan (“PLADESHi”).

• The National Energy Transition Strategy, prepared by SENER, will set 15-year and 30-year objectives for renewable-energy transition, sustainable use, energy efficiency, clean energy, Energy Justice, innovation, and technological development.

• PROSENER is defined as the short-term master planning instrument intended to give effect to the objectives of the National Development Plans.

• PLATEASE will establish planning goals for renewable energy, clean energy, energy efficiency, sustainable use, reduction of energy poverty, and the development of biofuels.

• PLADESE will include the regulatory framework for the electric sector, a diagnostic with at least 15 years of historical data, medium-term scenarios, and the investment programs and plans of PEMEX, CFE, and LitioMX.

• PLADESHi will replicate the structure of PLADESE for the hydrocarbons sector, also incorporating CENAGAS’s project portfolio and identifying capacity and infrastructure requirements that must be developed through private investment.

• Binding planning must be considered by SENER and the CNE when granting assignments, contracts, permits, concessions, and authorizations.

I.3. Programación de la planeación vinculante.

• In the electric sector, the PLADESE process begins annually in the year preceding its applicability, when CENACE and CFE submit their binding programs for the installation and retirement of power plants and their expansion and modernization programs for the national transmission grid and the general distribution networks, with a 15-year horizon. These programs will be reviewed and, where appropriate, approved and published as the PLADESE, while the Energy Planning Council oversees implementation.

• In the hydrocarbons sector, the PLADESHi will also follow an annual cycle led by SENER, without specifying the months in which each stage must occur. CENAGAS, PEMEX, and independent system operators will participate by submitting their five-year expansion plans. The CNE will issue a technical opinion on the draft, and the Energy Planning Council will issue observations before SENER approves and publishes the PLADESHi.

II. Transitional Regime.

• The National Energy Information System must begin operations no later than 180 business days after October 6, 2025, that is, by June 22, 2026.

• SENER will likewise have until June 22, 2026 to issue the obligations and requirements for acquiring clean energy certificates applicable for compliance during 2026–2028.

• As a one-time measure, the processes for preparing the Planning Instruments will not be required to follow the procedural steps set out in the Regulation.
