transmission lines in Memphis, TN with some pylons

This is a project to map and document all power facilities on the planet. This could be power lines, tower and substations. But also gas or oil lines.

Electric power

An ITO Map layer shows power=* and voltage=* on ways and areas.

Physical components


See Key:power.

Key Value Element Comment Rendering Photo
power plant Area Relation A place/industrial facility where power is generated. Individual generating units within the facility should be tagged as power=generator.
Huntly Power Station.JPG
power cable Way A way following the path of underground cables, such as the local 0.4 kV network between transformer stations, distribution boxes and cable connection points, or sea cables. Not to be confused with non-power supply cables such as cables for telecommunication. May be combined with voltage=*, circuits=* and location=*.

power compensator Node Area Several kind of power devices used to insure of power quality and network resilience.
Static VAR Compensator 2a.png
power converter Node Area An HVDC converter converts electric power from high voltage alternating current (AC) to high-voltage direct current (HVDC), or vice-versa.
Pole 2 Thyristor Valve.jpg
power generator Node Area A device used to convert power from one form to another. Use in combination with generator:source=*, generator:method=* and generator:output=*.

power heliostat Node A mirror of a heliostat device.
power insulator Node Way A device to protect a power line from grounding on supports
Power insulator.png
power line Way A way following the path of (overground) power cables. For minor power lines with poles and not towers, you may want to use power=minor_line. Useful combinations: voltage=*, cables=* and wires=*. Please see the respective feature pages for details.

Electric transmission lines.jpg
power minor_line Way A way following the path of (overground) minor power cables, supported by poles and not towers/pylons. (This isn't quite so simple, as sometimes larger towers are replaced by smaller poles made with a stronger material; a better distinction might be based on voltage).

power pole Node For single (often wooden or concrete) poles carrying medium/low voltage electricity cables.

power portal NodeWay Power supporting structure composed of vertical legs with cables between them attached to a horizontal crossarm
Power substation portal.jpg
power catenary_mast Node A catenary mast supports system of overhead wires used to supply electricity to electricaly powered vehicle equipped with a pantograph.
power substation Node Area A tag for electricity substations. These provide voltage step-up/step-down, switching, conditioning, etc. Substations may be large facilities (up to several acres) for very high voltage transmission lines or just small buildings or kiosks near the street for low voltage distribution lines. Useful combinations: voltage=*, substation=* and location=*, see the feature page for details.
power switch Node A tag for electricity switches which are devices which allow operators to power up & down lines and transformer in substations or outside.
French overhead power switch pole.jpg
power terminal Node Point of connection between overhead power lines to buildings or walls
power tower Node For towers or pylons carrying high voltage electricity cables. Normally constructed from steel latticework but tubular or solid pylons are also commonly used. Should not be used for medium or low voltage electricity conductors carried on single wooden poles which might be tagged power=pole. See power=tower for detailed tagging of tower types.

power transformer Node A static device for transferring electric energy by inductive coupling between its windings. Large power transformers are typically located inside substations.

Oil and gas power

An ITO Map layer shows man_made=pipeline and type=* on ways and areas.


  • man_made=pipeline "Here is a pipeline"
  • location=* underground|underwater|overground (optional)
  • type=value This can be <water|oil|gas|sewage|any substance> (optional)
  • operator=name <name of the company operating the pipeline> (optional)
