During the next decade, many utilities worldwide will undertake significant investments in their substation, feeder, and transformer automation technologies and solutions. All types of utilities, including investor-owned, municipal, vertically integrated, and distribution system operators (DSOs), seek to improve reliability, upgrade and replace aging infrastructure, and integrate new distributed generation (DG) resources into the grid. Navigant Research expects automation investments to cover many of the medium-voltage (MV) primary substations, MV distribution feeders, and low-voltage (LV) transformers and transformer substations worldwide through 2025. Among global regions, North America, Europe, and Asia Pacific have experienced the greatest penetration of distributed renewables and other resources that could cause disruptions to the grid. Distribution automation (DA) and substation automation (SA) solutions will enable all utilities to deliver on the promise of a self-healing smart grid. The next generation of digital automated distribution and substation feeders will use increasingly sophisticated digital and wireless monitoring, expanded functionality intelligent electronic devices, and increasing levels of automation. These feeders will also use new automated approaches via autonomous networking intelligent devices. According to Navigant Research, global annual DA and SA revenue is expected to grow from $7.6 billion in 2016 to $12.2 billion in 2025. This Navigant Research report analyzes the global market for DA and SA technologies, with a focus on three categories: distribution substation automation, feeder automation, and transformer automation. The report provides an analysis of the market issues, including drivers, barriers, and regulatory factors, and case studies associated with these solutions. Global market forecasts for revenue, segmented by category and region, extend through 2025. The study also examines the key technologies related to DA and SA, as well as the competitive landscape.
