Open Systems International, Inc. (OSI) and Mexican partner, Automatización y Tecnología Mexicana SA de CV (Atemex), have announced the implementation of a next-generation SCADA system for División de Distribución Noroeste of Comisión Federal de Electricidad (CFE) at its Distribution Control Center located in Hermosillo, Mexico.

División de Distribución Noroeste, who provides electric energy to over 1.7 million customers in the Northwest area of Mexico, is one of several CFE divisions throughout Mexico. The new control center is located in Hermosillo, the largest city and capital of the Mexican state of Sonora, and serves more than 292,000 customers by improving the support, reliability and efficiency of the electrical network.

Atemex and OSI have equipped División de Distribución Noroeste with OSI’s advanced Monarch (Multi-platform Open Network ARCHitecture) technology on the Linux platform, providing a truly open and scalable system to fulfill their needs well into the future. In addition to solving the inherent problems of their former legacy system, the flexibility of the Monarch platform will allow División de Distribución Noroeste to optimally cope with increases in energy demand. OSI, Atemex and División de Distribución Noroeste have formed a strong partnership and implemented a SCADA system with unmatched levels of dependability, effectiveness and maintenance ease.

The new system in Hermosillo includes Supervisory Control and Data Acquisition (SCADA), Web-based Graphical User Interface, Historical Information and Archiving System, Trending and Calculation subsystem, Open Database Connectivity, as well as DNP and ICCP communications.

“With the support and assistance of the CFE team at División de Distribución Noroeste in Zona Hermosillo, we are proud to announce the completed commission of the SCADA system. One hundred percent of the electrical network and distribution substations in the area are now under the supervision and control of an OSI monarch system. Atemex is thoroughly satisfied with the installation of OSI’s first system in Mexico, and we hope that with continued hard work and excellence in customer service, the coming years will see most of the control centers in Mexico using OSI technology,” said Luis Teran, president of Atemex. “With the active participation of the CFE team in Hermosillo, we have added redundancy features to the existing system without interrupting online system operation, which highlights the elegant design, ease of maintenance and use of the monarch system. The CFE and Atemex teams are very pleased with the system and process undertaken”.
