Flexible AC Transmission System technology is used in the power industry to improve the control and performance of transmission networks. By dynamically managing voltage and power flow on transmission lines through electronic devices, this technology enhances system operational flexibility, efficiency, and reliability.

The implementation of this technology provides the Brazilian power system with greater operational flexibility, enabling dynamic management of power flow and optimizing the utilization of existing transmission infrastructure. This enhances the utilization capacity of the installed network, mitigates overload risks, improves power supply reliability, and promotes operational efficiency gains in the National Interconnected System.

The deployment of this solution was facilitated by a structured planning process coordinated by the Ministry of Mines and Energy (MME). Based on studies conducted by the Energy Research Institute (EPE), it was determined that innovative technologies capable of increasing transmission capacity and optimizing the use of existing infrastructure were required.

Based on the technical recommendations from the studies, the MME incorporated the solution into the Electric Power Transmission Concession Plan (POTEE), which governs the expansion and reinforcement of the national transmission network. In subsequent steps, the National Electric Energy Agency (Aneel) authorized the execution of the works and established regulatory deadlines for the project to commence commercial operation.

The commissioning ceremony was attended by representatives from MME, Aneel, and EPE.
