Overall customer satisfaction was measured based on power quality and reliability; customer service; company image; billing and payment; price; and communications. The ratings are translated to a point system, for which 1,000 would be a perfect score. In the Midwest, customers of 16 utilities were surveyed, and the average utility score was 686. Aquila scored 719, good for third place behind E.ON U.S. and MidAmerican Energy.
KCP&L was No. 7 with a 704 score, and Westar was next to last at 641.
Ameren which serves parts of eastern Missouri and Illinois, was last in the Midwest at 612. Nationwide, businesses served by the 58 largest U.S. electric utilities reported improvements in four of the six factors measured, with customer service and billing and payment factors registering the largest increases. Ratings for power quality and reliability and communications factors have also increased, but company image and price ratings were flat.
The national average score was 697, its highest ever, and continued a steady upward trend since 2004.
The area utilities fared differently last summer in J.D. Power's survey of general electric customers. Seventeen Midwest utilities were included in that survey, and KCP&L improved to fifth in that group. Westar ranked eighth and was the most improved utility in the study. But Aquila didn't do so well, ranking 16 out of 20 utilities in a separate category for medium-size utilities.
