4. Interaction with other sectors

The planning and installation of power transmission and distribution systems depend on decisions deriving from higher-level (national, regional) planning processes devoted to regional development, general energy development, town and country planning, general power supply measures, etc. (cf. corresponding environmental briefs).

There is a direct connection to the power generating sector (cf. environmental brief Thermal Power Stations). As soon as power transmission is correlated to a particular power source, the environmental impacts of the latter, i.e., of power generation, demand consideration; high transmission losses also have environmental consequences in that they necessitate the generation of additional power.

The rights of way for transmission lines are extensively determined by the relative locations of the power plant and the power consumers. Particularly valuable biotopes and landscapes must be protected by routing such rights of way around them.

Coordination with existing or still-to-be-installed technical infrastructure (roads, railways, waterways, other supply lines, etc.) is not only possible but even necessary for, say, crossing airports, waterways, roads, etc. and for the parallel routing of power transmission and telecommunication lines - all in order to ensure the safe, reliable operation of all facilities concerned.

With regard to the reprocessing and disposal of transformer oil (with or without PCB content), please refer to the environmental brief Disposal of Hazardous Waste.
