Electric and natural gas utility Aquila Incorporated has sold off some of its properties. The Kansas City-based company says this week it sold natural gas operations in Minnesota, Michigan, and Missouri, and its electric operation in Kansas. All told, the spinoff nets Aquila almost 897-million dollars, which will make a big dent in the big debt that’s plagued the utility company. The uproar following Enron’s exposure and bankruptcy shook several energy traders including Aquila, and it left the market three years ago to get back to its core business, as a domestic natural gas and electric utility. Today, Aquila serves more than one-point-three million customers in Kansas, Colorado, Missouri, Nebraska, Michigan, Minnesota and Iowa.
