ComEd Live Prices: The Last 24 Hours, Every Five Minutes

The instrument above shows ComEd's Hourly Pricing rate as it moves. On this program you pay the real hourly market price for the energy part of your bill instead of the flat rate, so the number changes every five minutes. The panel reads the current price, and the trace behind it is the last 24 hours, so you can see the shape of the day at a glance. The prices come straight from ComEd's public pricing feed. We are not affiliated with ComEd and we take no commission on anything.

What is the ComEd hourly price right now?

The large number in the panel is the running average of the current clock hour. That average is the figure you are actually billed on for energy this hour, because each hour's charge is the average of the twelve five minute prices inside it. The trace fills in the rest: every point is one five minute reading, so a calm flat line means a quiet grid and a tall climb in the late afternoon means the grid is straining. The dashed line marks the 24 hour average, so you can tell at a glance whether this moment is above or below a normal day.

How do I read the live price chart?

Three things carry most of the meaning. The current price tells you where you are now. The 24 hour high, low, and average tell you how unusual now is, because on Hourly Pricing the same kilowatt hour can cost a few cents overnight and several times that on a hot afternoon. And the shape of the trace tells you when the cheap and expensive hours tend to fall, which is the pattern a household on this program learns to run its flexible loads around. Hover any point on the trace to read the exact price and time.

One honest caution. A low price right now is a fact about the grid, not advice about your house. Whether running a load in this hour is a good idea depends on your own usage, your own equipment, and the rest of your day, none of which a live price can see. This page shows you what is true; it does not tell you what to do.

Is there a ComEd hourly pricing table or app?

ComEd publishes its own Hourly Pricing app and a table view of the same feed, and the chart on this page is built from that same public data. What this page adds is the shape. A table gives you the raw numbers hour by hour, which is useful when you want the exact figure; a trace gives you the pattern of the whole day in one look, which is what tells you when the cheap and expensive windows actually are. We plan to add a plain table view of the current day here as well, for readers who want the numbers rather than the curve.

How is the real-time price set?

The price on the trace is the wholesale market price for the ComEd region, passed through to you without a markup. The program doing the passing is ComEd Hourly Pricing, which also goes by its formal name, ComEd Real-Time Pricing. Starting in June 2026, Hourly Pricing bills also carry a separate summer Capacity Charge tied to your peak draw during the grid's highest demand hours, which is a residential cousin of a commercial demand charge and is not shown in this energy price. So a full picture of a summer bill on this program has two moving parts: the hourly energy price you see here, and a peak charge set by your worst summer afternoons.

Would hourly pricing have saved you?

The live price answers "what is it doing now." It cannot answer the question that actually matters, which is "would this have saved me." That answer does not live in the price. It lives in your own usage, hour by hour, priced against these rates and compared to the flat rate you pay today. Your own ComEd data holds that answer, and the independent, no commission tool that reconstructs it from your hours is on its way, so you can see what you would have paid rather than trust a generic promise. It reconstructs your own history: not a projection and not a pitch.
