See below for common usage of the power tag:

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.

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 location=underground;underwater;overground.

power cable_distribution_cabinet Node In these cabinets, the 400-V circuits to the house connections, connection and transfer points of the regional utilities are branched. Other uses include distributions of the municipal street lighting.
power converter Node 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 Relation 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 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.

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 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.

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.

cables 2 / 3 / 4 / 6 / 9 / 12 / etc... Way Number of power-carrying cables represented by this way. The power line on the photo (click on it to see more details) has 6 double cables (the cable on top does not carry power) and thus may be tagged as cables=6 and wires=double.
circuits 1 / 2 / 3 / etc... Way Number of electrical circuits represented by this way. The tag may be used when the number of physical cables is unknown (often the case for underground cable connections) or when the number of circuits is different from cables=* divided by 3. The photo shows a power line that connects to a cable connection having two circuits and thus may be tagged as circuits=2.
Onder- en bovengronds.jpg
tunnel yes Way Notes that a line or cable is contained in a self-supporting tunnel that may also be used for other purposes such as road traffic or be provided for maintenance purposes. Cables buried underground should not use this tag but be tagged as power=cable and location=underground;underwater.
voltage … / 110000 / 220000 / 380000 / etc... Way Voltage of the power line.
Tower reference sign.jpg
wires single / double / triple / quad Way Number of wires per power cable. "single" (1), "double" (2), "triple" (3) or "quad" (4). The photo shows an example of "double".
power User Defined Node Way Area All commonly used values according to Taginfo
