Kentucky American Water files rate case with Kentucky PSC Kentucky American Water filed an application with the Kentucky Public Service Commission requesting a general rate increase for its customers. The request is driven by the approximately $58M in capital investments the company has made since last filing for a rate increase nearly three years ago, in February 2010. The company’s request, if granted in full, would increase the average residential customer rate by $5.76 per month -- from the current average of $32.75 per month to $38.51 per month -- based on an average monthly usage of 4,500 gallons. Even with this proposed increase, the cost of tap water for residential customers would remain at less than one penny per gallon, with the average residential customer receiving a day’s worth of quality tap water for approximately $1.27. Today’s request seeks an increase in total revenue of approximately $12.3M.
