The honest answer is that it depends on your home, and anyone who gives you a confident yes or no without looking at your usage is guessing. What follows is how the program actually works and the one thing that decides it, so you can tell whether it is worth looking at for your house.
What is ComEd Hourly Pricing?
Hourly Pricing changes the supply half of your bill, the energy itself. Instead of a flat cents per kilowatt hour rate, you pay the real hourly wholesale market price, which ComEd passes through without a markup. That price is set by the regional grid market and is averaged over each hour, so it moves all day and is not fully known until the hour has passed. ComEd publishes the live and day-ahead prices so participants can see them.
It does not touch delivery. ComEd still delivers your power and bills the delivery charges the same way regardless of the supply rate you are on.
What decides whether it saves you: when you use power
Because the price changes hour to hour, the entire question of whether Hourly Pricing saves you comes down to timing. A home that runs most of its load overnight and on mild days tends to sit in cheaper hours than the flat rate. A home that runs heavy air conditioning on hot summer afternoons sits in the most expensive hours of the year.
Those summer afternoons are the crux. Grid prices spike hardest on hot weekday afternoons, and starting in June 2026 ComEd also applies a Capacity Charge tied to how much power your home draws during those high demand summer hours. That second piece behaves like a residential version of a commercial demand charge: it is not about how much energy you use over the month, it is about your draw at the worst moments. Two homes using the same total energy can land very differently on both counts, depending on when that energy is used.
Does ComEd Hourly Pricing actually save money?
This is why a blanket "hourly pricing saves you 10 to 15 percent" claim is meaningless. The program can save a well timed home money and cost a poorly timed one more, and nothing about the average tells you which one you are. The variable that decides it, your hourly usage shape, is specific to your house and is exactly the variable a generic calculator does not have.
How to know if it is worth it for your home
There is a real answer, and it is not a forecast. Your meter already recorded your usage hour by hour, and the market already recorded what each hour actually cost. Put the two together and you can reconstruct exactly what you would have paid on Hourly Pricing over the last year versus the flat rate. That is a reconstruction of what already happened, not a projection of what might, which is the only honest way to answer the question.
We are building an independent tool to do exactly that on your own ComEd usage, with no commission and nothing to sell you. Until then, the takeaway is simple: do not switch on a general promise, and do not stay on a general fear. The answer is in your own hours, and it is knowable.
