I have some unfortunate news to bring to you all: the beloved South Main Street 13.8/4.8 kV distribution line in Waterbury, Connecticut has met its demise.
EVERSOURCE Energy has replaced every single pole on that line from 1077 to 2180 South Main Street. All the new poles feature fiberglass arms and 35 kV visetops.
In addition, the 4.8 kV underbuild has been stripped from the line over the entire rebuilt span. While any removal of 4.8 kV distribution is cause for concern, the level of concern here is relatively low since it was a spur on the end of one of many distribution lines. All the remaining 4.8 kV trunk and branch lines remain intact, and are likely to stay in service for several years.
This is, however, undoubtably a step in a long-term project to eliminate the extensive 4.8 kV distribution system in Waterbury.
Here is a view of the beginning of the rebuilt segment:

It has been placed on my "concern" list, though, since the 4.8 kV underbuild is a radial line less than a mile long, rather than a trunk line. It may meet its demise through EVERSOURCE's "trimming the ends" philosophy on the 4.8 kV grid.

Also, MDU has converted several 2400V and 7200V delta systems to 4160V and 12.5kV Y systems respectively, and at least 1 more conversion is in the pipeline.
