I am working on a survey report on Bullendale, a remote gold mining 
settlement in southern New Zealand, where the first industrial 
hydro-electric generating plant in NZ was commissioned in early 1886. 
The original dynamos and original electric motor are all still on site 
(although ruinous). I am trying to find out if any other such early 
hydro-electric schemes survive (either intact or archæologically) 
anywhere else in the world, with both generators and motors still in 
place.

Any information would be welcome.
