Brazil's electricity distribution network faces a modernization challenge: integrating 30+ GW of distributed solar generation into a grid designed for one-way power flow, while reducing technical and non-technical losses that exceed 15% in some regions.

ANEEL's Resolution 111/25 (June 2025) established 13 guidelines for distribution network digitalization, covering advanced metering infrastructure (AMI), real-time monitoring, demand response, and resilience to extreme weather. Utilities like CPFL, EDP, and Enel are deploying smart meters, automated reclosers, and distribution management systems.

The scale is enormous: Brazil has over 90 million electricity consumers across a territory larger than continental Europe. Smart grid infrastructure must work across dense urban São Paulo and remote Amazonian communities connected by single-phase lines. The technical challenge of managing bidirectional power flows from millions of rooftop solar installations — while preventing grid instability — is driving real innovation in distribution automation.
