Modernizing Brazil’s energy network management system



In recent years, Brazil has experienced robust economic development, evolving energy systems, growth of renewable and distributed energy generation methods, and uncertainties that are characteristic of an aging power grid infrastructure.


Brazilian Electric Sector (BES) provides electric service to 98 percent of the country’s population. The company believed that deployment and utilization of a modernized infrastructure was critical in order to meet the growing demand for high-quality service.#


High on their list of power grid priorities was investment in smart technologies that would help them meet the growing demand, reduce non-technical losses, provide redundancy, and capture real-time operating data.


Deployment of management systems, along with supervision and control systems that are geographically distributed nationwide – plus fully integrated and redundant – was essential to achieving the goal of a modernized electric infrastructure.


Addressing the national energy network management challenge meant integrating five energy management systems associated with the National Operations Center of the System (CNOS) and four regional operations centers. The new multi-site system – known as Reger (energy management system) – will support a completely integrated national network. Reger is based on a combination of well-established products, including Siemens’ Spectrum PowerCC Information Model Manager and Cepel’s Sage (open energy management system). It will provide consistent access to network management resources and ensure backup of valuable operating data.


The solution includes a world-class project architecture with associated resources and the latest-generation hardware platform with redundancy. There is resource allocation between operations centers and integration between the centers and the ONS technical database, reinforced with robust cyber security. A global database ensures information updating and consistency between all operations centers in real time. Geographically distributed, redundant, and integrated supervision and control systems are capable of supporting all operational functions. An innovative “evergreen” concept that guarantees critical information is continuously updated through the use of the latest available technology. 


The initiative establishes a unified supervision and control platform in the ONS operations centers, and each of them is capable of having their attributes assumed by another without jeopardizing the system. In addition to its greater reliability, the network is unifying and makes data more secure, giving operators better conditions for guaranteeing continuity in their supervision and control processes.
