Wide Variations in Networking Technologies Used for Substation Communications Noted

November 8, 2019.  Ellicott City, Maryland.  With nearly 100 officials from 30 countries participating in the 2019 Newton-Evans study of trends in protection and control practices, there were some wide variations noted in the use of networking technologies across the world.

Among 55 North American utility respondents, the most prevalent networking technologies in use during 2019 included SONET/SDH (40%), T1/E1 (33%) and a mix of T1/E1, SONET and packet-based (33%). This seems to imply that SONET is the leading technology among the sample. However, the two networking technologies to watch out for in the next 4 years are IP/MPLS and SDN; 18% plan to use IP/MPLS and 15% plan to use SDN by 2022.

The most prevalent networking technologies used in 2019 among the 42 international utility survey participants included SONET/SDH (31%), Industrial Carrier Ethernet (29%) and IP/MPLS (26%). Based on the survey sample, the leading technologies planned for development by 2020 include MPLS-TP (29%) and SD-WAN (24%).

The Worldwide Study of the Protective Relay Marketplace in Electric Utilities: 2019-2022 measures current market sizes and contains projections on a world region basis for the next few years. More than 35 topics are covered in the utility survey portion of this study with participation from nearly 100 utility P&C officials from countries around the world.  The complete four-volume study of protection and control practices and trends is available from Newton-Evans Research Company.  Details are available at https://www.newton-evans.com/product/the-worldwide-study-of-the-protective-relay-marketplace-in-electric-utilities-2019-2022/ .
