Values

See below for common usage of the power tag:

Key	Value	Element	Comment	Rendering	Photo
power	plant		A place/industrial facility where power is generated (electricity, heat, cold water, biogas...). Individual generating units within the facility should be tagged as power=generator.
power	cable		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	catenary_mast		A catenary mast supports system of overhead wires used to supply electricity to electricaly powered vehicle equipped with a pantograph.
power	compensator		Several kind of power devices used to insure of power quality and network resilience.
power	connection		A freestanding electrical connection between two or more overhead wires
power	converter		An HVDC converter converts electric power from high voltage alternating current (AC) to high-voltage direct current (HVDC), or vice-versa.
power	generator		A device used to convert power from one form to another. Use in combination with generator:source=*, generator:method=* and generator:output=*.	Depends on generator type
power	heliostat		A mirror of a heliostat device.
power	insulator		A device to protect a power line from grounding on supports
power	line		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.
line	busbar		Determines a power=line to a busbar.
line	bay		A bay connects an incoming circuit to a busbar assembly.
power	marker		A separate pole or pedestal sticking out of the ground, or a wall marker describing the distance to a cable or other feature.
power	minor_line		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		Poles supporting low to medium voltage lines (power=minor_line) and high voltage lines (power=line) up to 161,000 volts (161 kV).
power	portal		Power supporting structure composed of vertical legs with cables between them attached to a horizontal crossarm
power	substation		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		A tag for electricity switches which are devices which allow operators to power up & down lines and transformer in substations or outside.
power	switchgear		The switchgear comprises one or more busbar assemblies and a number of bays each connecting a circuit to the busbar assembly.
power	terminal		Point of connection between overhead power lines to buildings or walls
power	tower		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		A static device for transferring electric energy by inductive coupling between its windings. Large power transformers are typically located inside substations.
power	User Defined		All commonly used values according to Taginfo
