I don't know about hilly areas (many stations are next to dams), but they have to be built where the water flows through the turbines by gravity (i.e., does not have to be pumped).

Long Distance Communications these days is handled by Microwave Towers. The good news is that these towers can be placed large distances away from each other so large distances are covered.

The Romans built stone-paved roads which were covered with local rocks cut into squares or polygonal slabs of lava. These roads had a military purpose. They made the movement of soldiers and the delivery of supplies to troops at the front or stationed in garrisons much easier and faster. Their military nature was also shown in by the fact that they were usually built on a straight line, even when they crossed hilly areas. Traders also used these roads to transport their goods. They complained that the straight tracts over steep gradients made it very difficult for their laden wagons. After these complaints at least some of these tracts were redesigned to allow for less steep gradients. The paved roads covered 20% (80,500 kilometres, 50,313 miles) of the total network of roads (400,000 kilometres, 250,000 miles) in the Roman Empire.
