I work for a utility company and this is brilliant. One other issue that comes into play for inspections is right of way. My understanding of this is a bit fuzzy but is very interesting. Back in the day, if a power company had a transmission line on the property, they could just go out and service it. With modern infrastructure frequently being on top of one another, power lines, internet cables, pipes, this becomes a more complicated issue and so property management and the ability to access sites becomes a question. Drones can frequently go where people can't so in thick vegetation I can see this really working for surveying. Very cool.
