In France underground power lines maps are publicly available (and it
should be a standard practice, INSPIRE from EU encourage it)
Most of them aren't visible from the surface, sometimes you have red
markers and that's all.
Nevertheless it's useful to add them (with careful integration as to not
interfer with roads or something not related to) in OSM and there are no
issue with verifiability since the operator gives many information
All the best
