Hello, regarding the voltage information JCPL runs a BES Bulk Electric system of  a few 500, essentially all 230 and some 115kv which feeds the rest being 34.5kv substation voltage. Thought this might of been 69kv but clearly wrong. The name is very rough, I need to continue mapping it to figure it out more. Otherwise I hope that answers your question. Oh and if a source is not listed I most likely got the substation name from street level imagery. I had put out some generic map lines at one point working on cleaning them up and adding sources, otherwise essentially all future line mapping will have sources attached or be able to provide them.
