The power generation model was refined in 2013 and include some distinction
between a power plant and a power generator.
It would be convenient and sustainable to take care of this for this
Power generator only regard any kind of device which convert energy from
one sort to another. It should be mapped with power=generator
Power plant is the whole site and can be mapped with an area or a relation
if the power plant isn't enclosed with a fence (which is often the case for
hydro power plant).
power=plant is the tag currently approved.
The hydropower_project tag may be redundant with power=plant.
Currently, it may be useful to map power=plant sites features only.
Generators are supplementary information only used by specialized mappers.
It would be great to don't use any other custom power=* value to allow the
largest amount of mapper to work with these datas.
I'll add some in my spare time.
All the best
