es .. it does seem strange. Yet it is used for landuse=aquaculture so 
other 'land use' can be applied over water too .. at least that is the 
present situation.

Err the wiki https://wiki.openstreetmap.org/wiki/Tag:power%3Dgenerator 
says ...

small independent generators (such as domestic solar panels), especially 
those generating less than 1 MW, should not be tagged as a power plant. 
This is known as distributed generation.
