Originally proposed at Wikidata:Property proposal/Generic

   Done: annual energy output (P4131) (Talk and documentation)

Description	Annual energy output of a power plant
Represents	electricity generation (Q383973) (for electric power plants)
Data type	Quantity
Template parameter	"annual_generation" in en:template:infobox power station
Domain	power station (Q159719)
Allowed units	all energy units
Example	Three Gorges Dam (Q12514) → 87 TWh (2015)
Planned use	Add property to power station items
See also	nominal power capacity (P2109)

Motivation

There currently is no property to specify the annual output of a power plant. Ita140188 (talk) 03:28, 7 July 2017 (UTC)

Discussion

•  Comment There is nominal power capacity (P2109), but this would be different. I added it to the see also above.

Thank you. As you mentioned, this is different from capacity, as it refers to the actual generation in a given year. This is related to installed capacity by the capacity factor (which can be also calculated once both values are given) --Ita140188 (talk) 09:55, 10 July 2017 (UTC)

•  Comment A more generic "power output" property would be better. It can then have quantities added in "Kw per hour" or "Twh per year", or whatever, with our without a timestamp. Andy Mabbett (Pigsonthewing); Talk to Andy; Andy's edits 16:22, 7 July 2017 (UTC)

I think that in practice energy output is always given per year at the level of detail of Wikipedia, so it would be easier to just specify annual output, also for consistency Ita140188 (talk) 07:32, 8 July 2017 (UTC)

 Support I modified the suggested label, hope this is ok. ArthurPSmith (talk) 15:05, 10 July 2017 (UTC)

Hi, thank you for the support. However, I am not sure it is a good idea to use the word "power". The value should be an energy quantity (in a specified year), for example "kWh" or "MJ", as opposed to "kW". I think calling it "power output" could be confusing. Maybe "annual energy generation" or "annual energy output" would be preferable. --Ita140188 (talk) 06:04, 11 July 2017 (UTC)

good point - I changed it again to "annual energy output" ArthurPSmith (talk) 17:59, 11 July 2017 (UTC)

•  Done @Ita140188, ArthurPSmith: please make good use of it.
