I did a fair bit of it on oil wells a few years ago. My understanding was that it paid off for the customer in about 3 months, running 24 hours a day. With over 600 wells for one customer, how could it not pay off for the electrician?
In the case of an oil well, it is easy for the customer to track the savings (one meter per well with nothing else on the meter).
If you need to spend hours talking the customer into trying one, it may not pay off for you, and if they have a lot of other equipment, they may not notice the savings.

e57, The capacitor banks used by utilities are usually only used to correct the p.f on thier Distribution systems, to correct the Inductive effects of transformers, etc. Over here, large users of electricity are penalised by higher Tariffs, that have a power factor under a certain figure (0.65 lagging, I think).
