+/- power=generator Description A Place where power is generated. Used on these elements Useful combination generator:source=* generator:method=* generator:output=* name=* operator=* Status Undefined Tools for this tag Combinations worldwide in Australia/Oceania in Europe (list) in Asia (list) in Central America (list) in South America (list) in Africa (list)  (via overpass turbo - help)

A power generator is a facility for converting energy from one form to another, often for the creation of electrical energy from coal, oil, gas, wind, nuclear etc; a power generator may however also however create heat in the form of hot water as well as, or instead of creating electricity. A electrical power generator is linked to where power is required by power grid consisting of power=lines and power=sub_stations. The man_made=windmill tag should be used for traditional windmills and man_made=windpump for water-pumping wind wheels. The following tags are deprecated: man_made=power_wind, man_made=power_hydro, man_made=power_fossil and man_made=power_nuclear.

How to Map

Geometry

Add a node at the centre of the power generator or preferably create an area around the boundary of the facility using aerial photography if available. Tag with power=generator and also a name=* and operator=* of known. For an electricity generator there is likely to be an associated power=sub_station and power=lines.

Energy source

The energy source for the generator should be identified using the generator:source=* tag (power_source=* is obsolete). Example sources include:

• coal
• gas
• hydro
• nuclear
• oil
• solar
• wind

See generator:source=* for a complete list

Method of generation

The tag generator:method=* is used to describe the technical process or method used to convert the energy source into the energy output.

Suggested values:

generator:method=	combustion	Burning the fuel
	fission	Nuclear fission
	fusion	Nuclear fusion
	thermal	Using heat (e.g. from the sun)
	pumping	e.g. using geothermal heat
	photovoltaic	Using photovoltaic cells
	gasification	Gasifying the fuel, then burning it
	anaerobic_digestion	Breaking the fuel down with microorganisms in the absence of oxygen
	pyrolysis	Decomposing the fuel at a high temperature in the absence of oxygen
	dam	Hydroelectricity comes from the potential energy of dammed water
	pumped-storage	Hydroelectricity produced by moving water between reservoirs at different elevations. See Wikipedia
	run-of-the-river	Run-of-the-river hydroelectric stations are those with small or no reservoir capacity. See Wikipedia

Output power

The tag generator:output=* can be used to specify the forms of energy generated, and the rating if known.

Power generators can output multiple forms of energy. For example, a boiler will only output hot water, but a combined heat and power plant will typically output hot water and electricity. Add as many values as are relevant.

If the rating of the output is known, add a numerical value followed by the unit. Otherwise simply add 'yes'.

generator:output:electricity=*	yes / x W / x kW / x MW / x GW
generator:output:hot_water=*	yes / x W / x kW / x MW / x GW
generator:output:hot_air=*	yes / x W / x kW / x MW / x GW
generator:output:cold_water=*	yes / x W / x kW / x MW / x GW
generator:output:cold_air=*	yes / x W / x kW / x MW / x GW
generator:output:compressed_air=*	yes / x W / x kW / x MW / x GW
generator:output:steam=*	yes / x W / x kW / x MW / x GW
generator:output:vacuum=*	yes / x W / x kW / x MW / x GW
generator:output:battery_charging=*	yes / x W / x kW / x MW / x GW

Example

For example to tag a 15 MW biomass gasification combined-heat-and-power plant use:

power=generator

generator:source=biomass

generator:output:electricity=5 MW

generator:output:hot_water=10 MW

generator:method=gasification

Or to tag a solar thermal panel use:

power=generator

generator:source=solar

generator:output:hot_water=yes

generator:method=thermal

Or to tag a wind turbine (a modern electricity-generating wind mill):

power=generator

generator:source=wind

generator:output:electricity=3 MW
