The Romaine project is for the construction of 4 hydro-electric power stations each of 1.5GW. Such a scheme must already have communications links using either landline or satellite. Even is cellphones don't presently reach the area extending mobile coverage to enhance worker safety (both in construction and operation) might be the way to go.
What is the windspeed monitoring for as it would seem to be an amateur project rather than someting official?
