As power grids continue to evolve, they offer utilities and consumers the ability to better control and monitor use and are becoming increasingly important. Connected devices are offering greater control in various industries and smart meters are bringing the benefits of the Internet of Things (IoT) to electricity management. 

In Mexico, increasing attention is being paid to smart meters by the Energy Regulatory Commission (CRE). The CRE wants to ensure that the reporting of the systems in the registry display a more accurate amount of energy consumed. As a result, the new NOM-001-CRE/SCFI-2019 (Electrical Energy Measurement Systems-Instrument Meters and Transformers-Metrolological Specifications, Test Methods and Procedure for Conformity Assessment) is in the final stages of publication in the Official Journal of the Federation, which will in turn become law.   

NOM-001-CRE/SCFI-2019 is applicable to meters and measurement transformers that are used in processes for liquidation and billing purposes, as well as for measuring instantaneous quantities and power quality, which are involved in:

  1. The determination of electricity costs (local marginal price)
  2. The power market (related services)
  3. The availability of controllable demand
  4. The physical model of the network
  5. The evaluation of compliance with obligations and market rules

Prior to these more stringent requirements for Mexico, UL helped customers in meeting requirements set by the Federal Electricity Commission (CFE) by providing testing and certification for smart meters. As the regulations continue to evolve for Mexico, UL can help you obtain a better understanding of the new certification requirements and how they will apply to your products.
