How the Hourly Price of Electricity is Set

How the Hourly Price of Electricity is Set

The day-ahead hourly market prices are provided by MISO – the Midcontinent Independent System Operator, Inc. The hourly prices for “tomorrow” are typically made available between 3:30-5:00 p.m. Power Smart Pricing participants are billed based on these hourly prices, rather than the standard flat rate.

Ameren Illinois does not mark up the price of power, nor does Ameren Illinois profit from supplying Power Smart Pricing participants with electricity. You simply pay the market price.
