A spike in the cost of wholesale electricity is impacting summer cooling bills. Ameren Illinois does not generate electricity; it is purchased for our customers by a state agency and the costs are passed directly, dollar-for-dollar with no profit. This video provides a brief explanation of energy supply and delivery, along with steps you can take to lower your usage and save money. If you're having difficulty paying your energy bill, please explore AmerenIllinois.com/EnergyAssistance.
