"Much of this country has overhead service and switching to underground is prohibitively expensive."
That overhead HVMV service caused catastrophical fires in California and I think it also led to the utility went broke.
Some of the fire problems may have been the result of very poor relay protection systems.
A large number of utilities around the world use HV cable networks, and the longer ones must be HVDC.
Reduces the cost for purchasing right of way and yearly tree felling.
And does away with fire hazard and lightning power cuts
Many of the substations are also indoor GIS, which occupy around 12 % of an outdoor substation.
(My favorite outdoor substation in the US is the one near the Audubon facility close to the river in New Orleans, where large birds nest close to phases. Station also occupies a large area where I BELIEVE that real estate is very expensive)
And energy cost for consumers is around the same as in the US.
For off shore wind farms there is no alternative to cable.
