The Los Angeles Department of Water and Power owes its customers at least $67.5 million after the utility company overbilled them because of a faulty computer billing system that was launched in 2013, the Los Angeles Times reports. Because of a class-action settlement, customers will be refunded 100 percent of the amount they were owed by early next summer, and ratepayers have the right to make claims for “consequential damages” stemming from the billing problem.
