Off-Peak Times
Demand for energy is lower during these times, so you're charged less. These times vary by plan but are typically late at night and in the early morning.
On-Peak Times
Demand for energy is higher during these times, so you're charged more. These times vary by plan but are typically in the afternoon and early evenings.
Ameren Missouri now offers a range of residential rate options, including Off-Peak/On-Peak rates. With these rates, you can save by shifting your energy usage to off-peak hours, when demand is lower and you'll pay less. Finding the rate that's right for your lifestyle can add up to savings for you.
BASIC RATE: Less effort required for success on this rate.
How It Works
You’ll pay the same rate for all the energy you use. You don’t have to change your ways, but to save on this rate you'll have to use less energy.
Is this rate a good fit for you?
Do you want to keep things as simple as possible and keep using energy the way you do today? This is the rate you're familiar with – you are charged one rate for energy no matter when you use it. Residential customers with an AMR or an upgraded AMI-enabled meter qualify for this rate option.
Summer: June through September
Winter: October through May
Note: Rates are rounded to the nearest tenth of a cent.
BASIC RATE: Less effort required for success on this rate.
How It Works
You’ll pay a discounted rate on the energy you use between 9 p.m. and 9 a.m., so you can save if you shift some of your usage to that time window. For example, set the delay function on your dishwasher and other appliances to run at night. You'll be charged a rate that’s slightly lower than what you’ve been paying for energy you use from 9 a.m. to 9 p.m.
Is this rate a good fit for you?
Are you out of the house by 9? Do you spend most of the day at work? Do you run a few errands before coming home? To save on this rate, you need to change when you use energy. Coming in 2021; you must have an upgraded AMI-enabled meter to qualify for this rate.

How It Works

How It Works
You can maximize your savings if you distribute your energy use throughout the day and avoid on-peak hours, when energy is most expensive. For example, stagger the use of major appliances, and schedule usage with smart devices and programmable appliances.
This rate has a demand charge, which means that each month, your hour of highest usage between 6am – 10pm will be charged at a higher per-kW rate (see details below).
Is this rate a good fit for you?
Do you want to closely monitor the way you use energy and focus on off-peak use? Are you able to stagger how you use energy to save even more?
