Legal News: Energy Regulatory Commission – Grid Code 2.0
Version to print | January 2022
On December 31, 2021, the Energy Regulatory Commission (“CRE”) published, in the Official Gazette of the Federation (“DOF”), the “Resolution No. RES/550/2021 of the Energy Regulatory Commission by which the General Administrative Provisions containing the criteria of efficiency, quality, reliability, continuity, security and sustainability of the National Electric System are issued: Grid Code”[1] (the “Resolution”). This Resolution establishes the regulations on efficiency, quality, reliability, safety and sustainability of the national electric system (“SEN”) that must be applied for its development, maintenance, operation and planning.
The Network Code is the integration of all the general administrative provisions that contemplate the technical requirements for the correct and efficient development of the planning, control, operation, access and use processes of the SEN, therefore, the Resolution has as its main objective the issuance of the criteria that must be followed in order to guarantee the efficiency, quality, reliability, continuity, security and sustainability of the SEN, under an open and non-discriminatory access scheme of the electricity market.
The new Grid Code is composed of two main sections, which are divided into: a) general provisions of the SEN, and b) operational provisions of the SEN. The instrument also includes 12 (twelve) interconnection criteria for power plants, 11 (eleven) connection criteria for load centers and 8 (eight) criteria for electrical substation arrangements for the interconnection of power plants.
In order to achieve the above objective, various modifications were proposed to the Network Code, among which the following stand out:
- The scope of the regulation is modified in relation to the order of the technologies considered for the procedure for reducing generation due to reliability, which leads to greater discretion on the part of the National Energy Control Center (“CENACE”) in the procedure;
- The causes of liability applicable to generators are modified, especially those causes that lead to an interruption in the electricity supply;
- The technical requirements for the interconnection of power plants to the SEN are modified, and
- New requirements are imposed on the control of active and reactive power during power plant failures, which increases the costs of power plants.
In addition to the above, the Resolution is not clear about the regulation that will apply to load centers or power plants that intend to migrate from the legacy regime to the wholesale electricity market, especially regarding which version of the Grid Code would apply to them. That is, those power plants that are in trial periods or in the process of migrating to the MEM should adhere to the previous Grid Code, since their migration process was initiated prior to the entry into force of the Resolution. Otherwise, the application of the new Grid Code could be considered as an act of a retroactive nature, in violation of Article 14 of the Constitution.
