The numbers quoted for the Queensland plant referenced above would translate to about A$1.50, or US$1, for a thousand gallons. (10c/kWh for electricity according to [0]) There are running costs other than electricity, but it's always talked about as being power-intensive, so it seems fair to assume the cost of electricity dominates. $1 for a thousand gallons seems like a non issue for domestic use in developed countries. It's on par with the cheapest rates consumers currently pay in Europe, while some countries pay 8x more [1]. Even in most poor countries it should be attainable.
