Energy pricing bleg

GM asks:
Do you know whether power plants in the US are charged marginal rates for water withdrawals and "consumption" (e.g. through evaporation)?
I don't know, but I guess that they pay little or nothing, since their water either comes from a stream or their own wells, and marginal prices apply to treated water. (If there was a water market, we'd see the effects of marginal prices.)

Do you guys know?
