J.D. Power Names Ameren Illinois in List of Top Utilities for Business Customer Satisfaction

COLLINSVILLE, IL (December 2, 2019) – Ameren Illinois' progress in building a stronger energy infrastructure, offering energy management services, and implementing environmentally-friendly technology has landed the company among J.D. Power's top utilities in the nation for business customer satisfaction. J.D. Power surveyed business customers of 87 large U.S electric utilities; Ameren Illinois ranked 13th nationally and in the top five in the Midwest.

"We know that access to flexible, affordable energy is a key economic development driver, whether to manufacture goods, provide transportation, or run computers," said Richard Mark, Chairman and President, Ameren Illinois. "We're pleased to see that our business customers report that they are seeing the benefits of the investments we have made to strengthen the grid and provide superior service."

J.D. Power researchers conducted online interviews with business customers that spend at least $200 a month on electricity. Overall satisfaction was examined across six different categories: power quality and reliability, corporate citizenship, price, billing and payment, communications and customer service.

"We have worked hard to develop flexible programs that make it easy for our business customers to manage their energy usage and save money," Mark said. "Our Economic Development team is on the front line, providing individualized services that meet the unique needs of our business customers. The J.D. Power ranking is an indication that this strategy is working."

The following are benchmark scores of the top quartile of the Midwest large electric utilities surveyed.  Ameren Illinois sits 10 points above the average with a score of 793.  (All scores are based on an index of 1,000 points.)
