Francois, I'm aware of all that, I was just mentioning that unusual tag
because it was relevant in the current context. GautamPratik has not made
any changesets since the earthquake (
http://www.openstreetmap.org/user/GautamPratik/history), but maybe you
could send a message so if they do have a chance to get back to mapping
hydropower in the future, you could help them to use better tagging.
