After the storms had worked their way across Illinois Sunday evening, about 150,000 customers were without power.
In Illinois, Ameren crews are working to restore power to the remaining 13,000 customers. These include more than 4,500 AmerenCIPS customers, 1,500 AmerenCILCO customers and approximately 7,000 AmerenIP customers.
Ameren officials expect customer service in Illinois will be substantially restored by the end of today. However, scattered isolated outages may persist into tomorrow.
"Our employees and contractors continue to work the necessary extended hours to restore service to all of our customers in a timely and safe manner," says Scott Cisel, president of Ameren Illinois Energy Delivery.
"The loss of electric service not only is inconvenient, but is disruptive. All of us at Ameren appreciate the support and patience our customers have shown during the past few days."
Cisel says the storms brought down hundreds of poles and wires across Southern and Central Illinois.
Ameren's Web site www.ameren.com carries near- real-time information on outage numbers in its "Storm Center."
Ameren serves 2.3 million electric customers and nearly one million natural gas customers in a 64,000 square-mile area of Missouri and Illinois.
