How do peak-rate anomalies happen for Comed customers?
Comed serves approximately four million electric customers in Northern Illinois, including Chicago and its surrounding suburbs. The utility operates within the America/Chicago timezone and primarily utilizes Itron AMI smart meters to track energy usage. Customers can access their data through Green Button Connect My Data using OAuth 2.0 authorization_code or via a companion app API sync. This infrastructure supports various rate structures, including Hourly Pricing, Delivery Time-of-Day (DTOD), Peak Time Savings, and standard delivery options. Understanding how these rates interact is crucial for managing electricity costs, particularly during periods of high demand.
Peak-rate anomalies for Comed customers often stem from the specific timing of the Mid-Day Peak window. Under the Delivery Time-of-Day structure, this peak period runs from 1 PM to 7 PM. However, historical data indicates that hourly pricing tends to be highest between 3 PM and 7 PM on hot summer weekdays. This discrepancy creates a scenario where the official peak band begins earlier than the actual highest cost hours. Consequently, customers who shift usage to just after 1 PM might still incur high costs if they remain active during the 3 PM to 7 PM window, leading to unexpected charges that do not align with their perceived off-peak behavior.
The financial impact of these timing differences is significant. The DTOD Mid-Day Peak represents the highest delivery band, costing about 11.65 cents per kilowatt-hour for a published single-family gas-heat example in 2026. In contrast, traditional delivery costs about 5.9 cents per kilowatt-hour. This means the peak rate is nearly double the standard delivery cost. Furthermore, the cheapest delivery band occurs overnight from 9 PM to 6 AM, costing about 3.29 cents per kilowatt-hour on the same example. Hourly Pricing supply is also cheapest during nights and weekends. The difference between the peak rate and the overnight low rate highlights the substantial savings potential for customers who can accurately shift their consumption.
Interval monitoring is the key to navigating these complex rate structures. Comed provides hourly interval reads via Green Button Connect My Data or the companion-app API sync. This granular data allows customers to see exactly when they are using electricity relative to the changing rates. Youtilitics serves as a dashboard that charts this interval data, helping users visualize their usage patterns against the peak and off-peak windows. By analyzing these hourly reads, customers can identify if their usage aligns with the highest cost periods, such as the 3 PM to 7 PM window on hot days, and adjust their habits to avoid peak-rate anomalies. This proactive approach ensures that customers maximize savings by leveraging the lowest rates during overnight hours and weekends.
How do I interpret my Comed bill?
A Comed statement usually mixes fixed fees with usage-based charges. Reading line items alongside interval data is the fastest way to explain a surprise total.
- Customer/service charge — fixed fee independent of usage
- Usage (volumetric) charge — multiplies kWh, therms, or gallons by the rate or tier
- Delivery vs generation (electric) — sometimes shown as separate line items
- Taxes, franchise fees, and riders — vary by city and utility
- Time-of-use or tiered pricing — the same kWh can cost more at peak hours or higher tiers
- Compare your Comed usage history month to month; dollar totals alone hide weather and rate changes
What is a typical monthly usage for Comed customers?
There is no single “correct” monthly use—climate, home size, and appliances matter more than the utility brand. Use these U.S. residential electricity benchmarks as a starting point, then compare against your own Comed history:
- Typical U.S. household electricity use: about 855 kWh/month
- National-average residential rate context: about 16.2¢/kWh (approx. 2024–2025 EIA ranges)
- Illustrative energy cost at those averages: roughly $140/month before fixed fees
- Your best benchmark is last year’s same month from Comed, not a national average

How can I lower my Comed bill?
- Track daily or hourly usage so a single high bill does not stay a mystery
- Cut continuous loads first (leaks, stuck valves, always-on equipment)
- Shift flexible loads (EV, dishwasher, laundry) to off-peak windows when available
- Identify baseline kW at night; vampire load often costs ~$100+/year per household
- Tune HVAC: 1–2°F setback, filter changes, and sealing duct leaks
- Upgrade high-use lighting and appliances to ENERGY STAR where payback is clear
- Re-check charts after each change to confirm the drop before the next bill
What features help with Comed data?
- Automatic or regular sync of electricity history from Comed
- Clear charts that show how much you use and when
- Alerts when usage jumps—useful for leaks, irrigation faults, or HVAC issues
- One place to track electricity trends without digging through PDFs

How does it work with Comed?
Youtilitics analyzes your electricity consumption with Comed. Follow these steps:
- Connect your utility account. Link Comed (or upload Green Button / usage files) so Youtilitics can import meter history.
- Review charts for spikes and baseline load. Look for overnight baseline, irrigation peaks, EV charging windows, and HVAC ramps that drive the bill.
- Fix or schedule the biggest loads. Repair leaks, reprogram irrigation, move EV charging off-peak, and adjust thermostat schedules.
- Confirm savings with alerts and follow-up charts. Use spike alerts and month-over-month charts to verify usage dropped after each change.
This utility is supported by the Youtilitics app. Create an account and download the app to track your usage.
Do I need to check Youtilitics every day?
No. Systems check your usage routinely and can alert you if there is a sudden spike—so you hear about problems before the paper bill arrives.

Frequently asked questions
How do I interpret my Comed bill?
Most Comed bills combine fixed charges (service/customer fees) with usage charges based on electricity consumed. Compare total usage to prior months, note any tier or time-of-use periods, and look for unusual spikes. Youtilitics charts the same meter data so you can see when usage rose instead of only seeing a dollar total.
When are Comed peak hours?
Comed peak hours are Mid-Day Peak 1 PM – 7 PM on Delivery Time-of-Day; Hourly Pricing historically highest ~3 PM – 7 PM on hot summer weekdays. Published context: DTOD Mid-Day Peak is the highest delivery band (about 11.65¢/kWh for a published single-family gas-heat example vs about 5.9¢/kWh traditional delivery in 2026) versus DTOD overnight 9 PM – 6 AM is the cheapest delivery band (about 3.29¢/kWh on that same published example); Hourly Pricing supply is cheapest nights and weekends. Interval charts show whether EV charging, HVAC, or appliances actually landed in that window.
What is a typical monthly usage for Comed customers?
Usage varies by home size, climate, and appliances. As a U.S. residential electricity benchmark, many households use roughly 855 kWh per month (about $139 at a national-average rate near 16.2¢/kWh). Your Comed history is the best baseline—compare your own months rather than a single national figure.
Can Youtilitics connect to Comed?
Yes. Comed is certified for Green Button Connect My Data (OAuth 2.0). Link your account once and Youtilitics imports interval history automatically.
How can I lower my Comed bill?
Start with visibility: track electricity daily or hourly to find peaks. Common wins include fixing leaks or continuous irrigation, shifting EV charging off-peak, reducing baseline “always-on” load, and tuning HVAC setpoints. Then re-check the same charts after each change to confirm savings.
