Frequently Ask Questions

  • Hourly Pricing Open or Close

    • What is ComEd's Hourly Pricing?

      ComEd’s Hourly Pricing is an electric supply rate that lets you pay for electricity at the hourly market price.

      Unlike fixed rates, hourly rates fluctuate up and down throughout the day and night. So when you participate in Hourly Pricing, you can save money on your electric supply costs by shifting some of your energy use to times when the price of electricity is lower.

    • How much can I save?

      Hourly Pricing participants have saved an average of 15% on their electric supply costs compared with what they would have paid on ComEd’s default fixed-price rate.*

      *Savings percentage based on the electric supply section of participants’ energy bills from 2007 to 2023. Savings cannot be guaranteed. Individual bills and savings vary month-to-month based on weather, market conditions, and individual energy usage habits. The more you can shift energy usage to lower-priced times, the more you could save with Hourly Pricing.

    • Is Hourly Pricing right for me?

      You may be a good fit for Hourly Pricing if you can shift energy use to off-peak times, when prices are lower than the default fixed-price rate. Visit ComEd My Rates Comparison and see if Hourly Pricing would work for you. 

    • How will I know when prices will be high?

      You can elect to receive Hourly Pricing Alerts, which will let you know when prices could be high. Alerts can be sent via text message, email, or automated phone call.

      An alert that tells you to save energy immediately is sent when the real-time market price of electricity is trending high. When the 5-minute price is at or above 14 cents per kilowatt-hour (kWh) for 20 consecutive minutes, an alert will be triggered and you will be notified based on the alert method you chose.

      An alert that tells you in advance to reduce your energy use tomorrow during specific hours can help reduce the Capacity Charge on your future bills. This is different from an alert caused by high prices.

      Real-time prices and day-ahead prices (after 5 p.m. CT) are available on the Prices page or by calling 888-202-7787.

    • Are there price caps or other energy price protections in place to help ComEd customers on the Hourly Pricing rate from paying high energy costs?

      Yes. Participants pay a rate based on the market-based hourly energy price for electricity. However, the market operator, PJM, caps the hourly energy price for electricity at a maximum of $3.70 / kWh. But please keep in mind the following important points:

      • Over the long run, most ComEd customers save on Hourly Pricing versus ComEd’s default fixed-price rate. Hourly Pricing has saved participants $40 million since its launch in 2007.
      • Hourly Pricing’s energy supply costs have never reached $3.70 / kWh and have only exceeded $1.00 / kWh for less than 0.1% of hours over five years (15 hours between 2019 and 2023).
      • High-priced spikes for energy in the ComEd service territory are usually temporary and not sustained.
      • Although ComEd doesn’t control the market price of energy and does not mark up the price you pay for any of the energy it delivers, ComEd does offer Budget Billing as a way to smooth out large monthly variations in your electric bill.
    • Is it true I’ll need a new meter to be enroll in Hourly Pricing?

      Enrollment in Hourly Pricing requires an electric meter, like a ComEd smart meter, capable of measuring and recording electric usage at hourly intervals. ComEd’s smart meters are capable of this. Other than your current monthly Standard Metering charge, there is no additional monthly meter lease fee for this hourly recording feature of the smart meter. If you have more than one meter at your premises, then you are currently subject to a regular monthly meter lease fee and that will not change. It is likely that each meter associated with your ComEd account is a smart meter

    • How can I take advantage of the difference between Hourly Pricing and the default fixed-price rate?

      If you shift the use of large appliances like your air conditioner, laundry machines and dishwasher to lower-priced hours – like evenings, nights, and weekends – it potentially could make a difference in your energy bills.

    • How long must I remain on Hourly Pricing? And is there a fee?

      Hourly Pricing participants may request to leave Hourly Pricing at any time; however, you may not rejoin Hourly Pricing for a period of 12 months following the termination. There is no fee to participate in Hourly Pricing.

    • How do I opt out of Hourly Pricing?

      If you decide Hourly Pricing is not the best fit for your household and would like to return to ComEd’s fixed-price rate, please contact us at info@ComEdHourlyPricing.com or 888-202-7787.

      Participants may request to leave Hourly Pricing at any time. Please note that all rate changes occur with a new billing cycle and the opt-out process may take 1-2 billing cycles. However, you may not rejoin the rate for a period of 12 months following the opt-out.

    • Are there any environmental benefits from being in ComEd's Hourly Pricing?

      Yes, Hourly Pricing has made a positive impact on the environment. Managing your energy use more efficiently can lead to cleaner air and a healthier environment for future generations. Hourly Pricing participants develop a higher awareness of their energy usage and, as a result, tend to use less energy overall.

      Since 2007, participants have reduced pollutants that cause acid rain and reduced emissions that contribute to climate change.

    • How are hourly prices determined?

      ComEd does not set the price of each kWh of energy that Hourly Pricing participants pay, nor does ComEd mark up or make any profit on the price of electricity. Market conditions, including weather patterns, determine prices, and the hourly prices are passed along. Transmission constraints can produce higher prices.

  • Billing FAQs Open or Close

    • What are the charges that appear on my Hourly Pricing participant bill?

      Some of the line items and charges will be the same for both participants in ComEd’s Hourly Pricing and for customers on ComEd’s default fixed-price rate. Some line items will be different or will be calculated based on different rates. Below, you will find more information about the line items on your bill and how the charges for Hourly Pricing participants differ from the charges for customers on the default fixed-price rate. All charges on ComEd bills are based on tariffs and riders approved by the Illinois Commerce Commission. ComEd’s full rate book is available online at ComEd.com/Rates and should be considered the official record for these items. The core components of all bills are the same. They include Electricity Supply Charges, Delivery Service Charges, and Taxes and Fees. These components are broken into the following line items on participants’ bills. Most line items appear on both Hourly Pricing bills and default fixed-price rate bills. Those that appear only on Hourly Pricing bills or are calculated differently for Hourly Pricing participants are indicated below.

      A. Electricity Supply Services cover the actual supply of electricity (either ComEd’s fixed-price rate BES Electricity Supply Charges or the special combined hourly rate of Rate BESH and Rider RRTP Electricity Supply Charges).

      • Electricity Supply Charge (calculated differently for Hourly Pricing)
      • Transmission Services Charge (calculated differently for Hourly Pricing)
      • Capacity Charge (this is a separate line item for those participating in Hourly Pricing; the Capacity Charge is already included in the Fixed-Price Rate Electricity Supply Charge)
      • Purchased Electricity Adjustment (calculated differently for Hourly Pricing)
      • Misc Procurement Component Chg (separate Hourly Pricing line item; costs included in Fixed-Price Rate Electricity Supply Charge)

       

      B. Delivery Services – ComEd covers billing and delivering the electricity supply to your home via distribution lines.

      • Customer Charge (same for Fixed-Price Rate and Hourly Pricing)
      • Standard Metering Charge (same for Fixed-Price Rate and Hourly Pricing)
      • Distribution Facilities Charge (same for Fixed-Price Rate and Hourly Pricing)
      • IL Electricity Distribution Charge (same for Fixed-Price Rate and Hourly Pricing)

       

      C. Taxes and Fees

      • Environmental Cost Recovery Adjustment (same for Fixed-Price Rate and Hourly Pricing)
      • Energy Efficiency Programs (same for Fixed-Price Rate and Hourly Pricing)
      • Franchise Costs (same for Fixed-Price Rate and Hourly Pricing)
      • Taxes (same for Fixed-Price Rate and Hourly Pricing)
      • Zero Emission Standard (same for Fixed-Price Rate and Hourly Pricing)
      • Renewable Portfolio Standard (same for Fixed-Price Rate and Hourly Pricing)
      • Energy Transition Assistance Charge (same for Fixed-Price Rate and Hourly Pricing)  
      • Carbon-Free Resource Adjustment (same for Fixed-Price Rate and Hourly Pricing)  
    • How does your Hourly Pricing bill differ from a default fixed-price rate bill?

      Most line items are the same for all residential customers, and most are charged at the same rate:

      • All standard delivery service related charges are the same.
      • Taxes and Fees will use the same rates for both Hourly Pricing and default fixed-price rate customers.

       

      Some line items and charges on your Hourly Pricing bill will differ from the default fixed-price rate:

      • Under supply related charges, all customers will have an Electricity Supply Charge, a Transmission Services Charge, and a Purchased Electricity Adjustment. However, the rates for these line items are different for Hourly Pricing and default fixed-price rate customers.
      • Hourly Pricing bills include separate line items for the Electricity Supply Charge, the Capacity Charge and the Miscellaneous Procurement Component Charge. Default fixed-price rate bills include the costs for these three items in a single line item (listed as Electricity Supply Charge).
    • What are the differences in how charges are calculated under ComEd's Hourly Pricing vs. ComEd’s default fixed-price rate?

      A. The Electricity Supply Charge

      ComEd’s fixed-price rate Electricity Supply Charge is based on the costs of procuring power, which are incurred pursuant to the Illinois Commerce Commission-approved procurement plan. This Electricity Supply Charge includes the cost for the electric energy, capacity, and other miscellaneous services and procurement costs. All of these components are purchased together and combined into one Electricity Supply Charge for default fixed-price rate customers.

      The Hourly Pricing Electricity Supply Charge is based on the ComEd Zone PJM real-time hourly prices, but it does not include capacity costs or miscellaneous services and procurement costs. Therefore, Hourly Pricing participants have a separate Capacity Charge line item and a Miscellaneous Procurement Component Charge line item.

      ComEd does not profit from the Electricity Supply Charges; it simply passes through the cost of supplying electricity to its customers.

      B. Transmission Services Charge and Purchased Electricity Adjustment

      The Transmission Services Charge is different for Hourly Pricing participants than it is for customers on the default fixed-price rate because the supply for Hourly Pricing participants is procured differently (directly through PJM rather than through the Illinois procurement processes). For a similar reason, Hourly Pricing participants’ Purchased Electricity Adjustment (PEA) charge or credit is different from the charge or credit for default fixed-price rate customers. ComEd does not mark up or profit from these charges. They are simply a pass-through of costs incurred by ComEd.

    • Why do I pay a different Transmission Services Charge with ComEd's Hourly Pricing?

      Transmission Services Charge under ComEd’s default fixed-price rate

      ComEd purchases transmission services for all default fixed-price rate customers in regional markets regulated by the Federal Energy Regulatory Commission (FERC). This charge is then apportioned to different customer groups on the default fixed-price rate, resulting in different Transmission Services Charge rates for residential, commercial and industrial customers.

      Transmission Services Charge with ComEd’s Hourly Pricing

      ComEd purchases transmission services for all hourly rate customers in regional markets regulated by the Federal Energy Regulatory Commission (FERC), so the same Transmission Services Charge rate is charged to all hourly customers (residential, commercial, and industrial).

    • What is the Purchased Electricity Adjustment?

      The Purchased Electricity Adjustment (PEA) acts as the balancing mechanism to assure that ComEd’s supply charges exactly match supply costs over time. This balance is reviewed monthly, and the charge rate is adjusted accordingly. ComEd’s revenues track the actual payments that ComEd must make to procure supply service.

      The PEA can be a charge or a credit that addresses the difference, if any, between the actual amount of money collected from ComEd’s customers for electricity supplied and the cost incurred to supply that electricity.

      The supply costs are tracked (and the PEA is adjusted) separately for different customer groups. As a result, the Purchased Electricity Adjustments may differ between Hourly Pricing participants and customers on the default fixed-price rate.

      Please see ComEd’s Entire Schedule of Rates for Electric Service sheets No. 37-39 for more information related to the PEA Factor.

    • Why do I still have to pay ComEd’s Standard Metering Charges?

      The delivery services that ComEd provides include standard metering charges for all the different customer classes that ComEd supplies. Thus, there is a Standard Metering charge for all ComEd residential customers, and this includes one smart meter per account.   

      Enrollment in Hourly Pricing requires an electric meter capable of measuring and recording electric usage in hourly intervals. ComEd’s smart meters are capable of this. Other than your current monthly Standard Metering charge, there is no additional monthly meter lease fee for this hourly recording feature of the smart meter. If you have more than one meter at your premises, then you are currently subject to a regular monthly meter lease fee and that will not change. Each meter associated with your ComEd account must be a smart meter with the hourly recording feature in order to participate in Hourly Pricing.

    • What is the Capacity Charge?

      The Capacity Charge covers ComEd’s costs to reserve enough electricity to meet demand at all times, including peak hours. Capacity Charges essentially allow ComEd to reserve generating capacity in advance, ensuring that enough electricity will be available when it is needed. All electricity suppliers are required to reserve capacity to cover their customer’s Capacity Obligation. The Capacity Obligation represents your expected level of hourly usage in the afternoon on a hot summer day.

      For residential customers who pay the default fixed-price rate, capacity costs are included in the Electricity Supply Charge. For Hourly Pricing participants, the Electricity Supply Charge does not include these capacity costs. Instead ComEd lists this charge as a separate line item on Hourly Pricing bills (labeled as the Capacity Charge). As the market price of capacity fluctuates, both default fixed-price rate customers and Hourly Pricing participants will see adjustments to their rate. The Capacity Charge item on your bill is adjusted every year in June. ComEd does not profit from the Capacity Charge. Instead, ComEd simply passes through capacity costs to its customers without mark up.

      Check out these two videos to learn more about your Capacity Charge and how you can save even more when you reduce it.

       

    • How is the Capacity Charge calculated?

      There are two components to this charge, your Capacity Obligation and the Capacity Charge rate. Multiplied together, they make up the Capacity Charge item on your bill. The method used to calculate your individual Capacity Charge depends on when your Hourly Pricing meter was first installed.

      Capacity Obligation

      If you were enrolled in Hourly Pricing during the previous summer, your Capacity Obligation starting in June is calculated based on your individual hourly electric energy usage data from the previous summer. In this case, ComEd calculates your highest electricity demand (adjusted for Transmission and Distribution losses) coincident with the five hours of the summer when the overall PJM System demand was highest (PJM Coincident Demand) (this has historically occurred between noon and 6 p.m. on weekdays) and the five hours of the summer when ComEd’s System demand was highest (ComEd Coincident Demand). These two sets of five coincident demands are averaged and adjusted for certain PJM factors to determine your contribution to the system load, creating your Capacity Obligation.

      Your Capacity Obligation is then used to calculate your individual Capacity Charge. So, the higher or lower your demand was during those ten peak hours (coincident with the five PJM System peak hours and the five ComEd System peak hours) of last summer, the higher or lower your Capacity Charge will be this year beginning with your June Billing Period.

      Similarly, if you had a smart meter the previous summer, but were not on Hourly Pricing, your Capacity Obligation is based on your individual hourly electric energy usage data from the previous summer, as long as the data can be validated. For months it can’t be validated, the class average method described below is used.

      If you had an older style meter (non-smart meter), your Capacity Obligation starting in June is based on the class average profile adjusted for your individual electric energy usage data from that previous summer. (ComEd’s four residential customer classes are: Single Family Non-Electric Space Heating, Single Family Electric Space Heating, Multi-Family Non-Electric Space Heating, and Multi-Family Electric Space Heating).

      Capacity Charge Rate
      The Capacity Charge Rate is updated each June based on the cost of capacity in the PJM wholesale market.

    • How can I reduce my Capacity Charge in the future?

      Reducing your electric energy usage during peak hours (which have historically occurred between 2 p.m. and 6 p.m. on the hottest weekdays of the summer) could lower your Capacity Charge on future bills.

      In general, the price of electricity goes up when demand is high, so the peak system load is likely to correspond with higher real-time prices. This means that if you can reduce your electric energy usage when prices are high, you’ll also have a good chance of reducing your demand during peak system load. This in turn may result in a lower Capacity Obligation, and thus, a lower Capacity Charge in the future.

    • What is the Miscellaneous Procurement Component Charge?

      The Miscellaneous Procurement Component Charge is a line item for Hourly Pricing participants only. It is itemized on your bill to make it easier to compare the total supply costs under Hourly Pricing to those on the default fixed-price rate. This charge recovers the costs that ComEd incurs related to procuring electric power and energy directly from PJM-administered markets for customers with hourly energy pricing that are not recovered through the application of the Capacity Charge, the Electricity Supply Charge, and the Transmission Charge. Similar costs for customers on the default fixed-price rate are included in their Electricity Supply Charge.

    • What is the IL Electricity Distribution Charge?

      The IL Electricity Distribution Charge is the same for both Hourly Pricing participants and customers on the default fixed-price rate. This charge recovers the Illinois Electricity Distribution Tax and uncollectible costs associated with the application of that tax. This is not a new charge. It appears as a separate line item in the Delivery Services section of the bill.

    • What is the Customer Charge?

      The Customer Charge is calculated the same way for both Hourly Pricing participants and customers on the default fixed-price rate. The Customer Charge recovers costs such as the standard service connection, customer service operations and billing. The Customer Charge also includes charges from Rider RCA for state funds for renewable energy resources, coal technology development, low-income energy assistance and Hourly Pricing cost recovery charges. This is a $0.06 monthly charge that all residential retail customers (including those taking service under Hourly Pricing) are billed. This charge is subject to change as allowed by the Illinois Public Utilities Act.

    • What is the Renewable Portfolio Standard?

      This charge helps support the procurement of renewable energy credits (RECs) to meet requirements set forth in the Illinois Power Agency Act. The Renewable Portfolio Standard rate is 0.502 cents per kWh for all ComEd Retail customers. These rates are currently applicable through August 2023. For more information on the Renewable Portfolio Standard, visit Renewable Energy 101.

    • What is the Zero Emission Standard?

      This line item supports zero-carbon energy supplied to Illinois and is the same rate for all residential customers.

    • What is the Energy Efficiency Programs charge?

      The Energy Efficiency Programs charge is the same for all residential customers. This charge recovers costs related to ComEd’s energy efficiency and demand response plans, which were approved by the Illinois Commerce Commission. This includes programs that are developed, implemented, or administered by or for ComEd or the Department of Commerce and Economic Opportunity (DCEO). ComEd does not mark up or profit from these charges.

    • What if I am a Net Metering customer?

      If you are currently participating in ComEd’s Net Metering program, you could maximize your excess energy generation credit when switching to the Hourly Pricing rate. On Hourly Pricing, net metering credits are calculated as a dollar value at the time of generation and at the hourly market price. If credits exceed the cost of your bill, excess credits are applied to the following billing cycle.

      Learn how you could maximize your energy savings with Net Metering and Hourly Pricing by visiting our Solar Generation page.

      For more information on your current credits or the Net Metering program in general, call 800‑825-5436 or visit the ComEd Net Metering webpage.

      Community solar customers can also apply for Hourly Pricing! Please contact us for more information.

    • What if I’m a customer who uses electricity to heat my home?

      Customers who heat their homes with electricity (via an air source heat pump, for example) tend to have higher energy usage in the fall, winter, and spring. Historically, hourly market energy prices tend to be lower during the colder months and overnight, meaning you could save money when heating your home on Hourly Pricing.

      Learn how you could create a home full of savings with Hourly Pricing by visiting our Electric Heating page.

    • Does Hourly Pricing work with Budget Billing? 

      Yes! With Budget Billing, you can enjoy a consistent and predictable monthly payment throughout the year that eliminates monthly or seasonal variation. Budget Billing spreads costs evenly month to month by charging a pre-arranged amount with each bill.

      Your monthly bill payment is based on your usage during the last 12 months. 

      Your actual usage will continue to be shown on your monthly bill. 

  • Price Alerts / Notifications Open or Close

    • How and when will I know the best times to save energy?

      Hourly Pricing Alerts will tell you to either reduce now or tomorrow. Alerts are sent when electricity prices are trending high or when energy is expected to be in high demand the following day. No matter when an alert tells you to reduce, just take the same actions you normally would, like delaying the start of major appliances or raising your air conditioner thermostat by a few degrees.

      You can choose to receive alerts via text message, email, or automated phone call. To make changes to your alert communication preferences, sign in to your My Hourly Pricing Account or email us at info@ComEdHourlyPricing.com.

      Check out the video below to learn how Hourly Pricing Alerts can help you save now and in the future.

    • How do Hourly Pricing Alerts work?

      An alert that tells you to save energy immediately is sent when the real-time market price of electricity is trending high. When the 5-minute price is at or above 14 cents per kilowatt-hour (kWh) for 20 consecutive minutes, an alert will be triggered, and you will be notified based on your personal preference.

      An alert that tells you in advance to reduce your electricity use tomorrow during specific hours can help reduce the capacity charge on your future electricity bills. This is different from an alert caused by high prices, but the idea is the same: reduce to save.

      You can learn more or change your alert communication options in your My Hourly Pricing Account or you can email us at info@ComEdHourlyPricing.com.

  • Central AC Cycling Open or Close

    • What is ComEd’s Central AC Cycling?

      ComEd’s Central Air Conditioning (AC) Cycling is a demand response program for central air conditioners that allows homeowners like you to earn credits on your bill.

      Customers enrolled in ComEd’s Peak Time Savings program are ineligible to enroll in Central AC Cycling. If you wish to enroll in Central AC Cycling, please visit the Peak Time Savings enrollment page to remove your home from the program before enrolling in Central AC Cycling.

    • How does ComEd’s Central AC Cycling work?

      Once you enroll, ComEd will install a special switch on your central air conditioning unit that allows them to cycle your air conditioner’s compressor off and on during hot summer days when demand for energy is highest. In return, you will receive a credit on your June through September ComEd bills.

    • How much can I earn?

      Depending upon which option you choose, you can earn a total annual credit of either $20 or $40 by giving up a few degrees of cooling during certain summer days. If you select the 50% option, you will receive a $5 credit on your June through September bills. If you select the 100% option, you will receive a $10 credit on your June through September bills. If you have more than one central air conditioning unit, all units in your household will need to have a switch installed to participate, but the credit remains $5 or $10 per household per month.

    • Will the switch that ComEd installs harm my air conditioner?

      No. Each switch is tested before installation. Use of the switch has been approved by top air conditioner manufacturers including Carrier, York, Lennox, and Trane and will not affect the warranty of your unit.

    • Can I really make a difference by signing up?

      Yes! Managing your energy use more efficiently can lead to cleaner air and a healthier environment for future generations. By participating in ComEd’s Central AC Cycling, you can reduce your energy use while earning bill credits. In addition, even the smallest energy reduction helps save natural resources. Each summer that ComEd has used the switch, ComEd’s Central AC Cycling participants have reduced greenhouse gas emissions that contribute to global warming and acid rain.

    • I have more than one air conditioning unit. Can I get more credits?

      No. Since air conditioner efficiency varies, ComEd can only offer a $5 or $10 credit per household per month. If you have more than one central air conditioning unit, all units in your household will need to have a switch installed to participate.

    • I have a portable or window air conditioning unit but not a central air conditioner. Am I able to participate?

      No. ComEd’s Central AC Cycling program requires your household to have a central air conditioning unit.

    • Will ComEd continue to maintain the control switch to ensure that it is operating correctly?

      Yes, ComEd will inspect the control switch periodically. If the control switch becomes disconnected or you install a new unit, you will need to contact ComEd.

    • How does ComEd decide when to use the switch?

      It depends on overall demand for electricity, which is usually dictated by the weather. Typical peak demand occurs on summer weekday afternoons when the temperature is extremely hot and the humidity is high.

    • Will I notice a change in the temperature inside my house when the switch is activated?

      Only your air conditioner’s compressor is cycled. The fan stays on, circulating cool air and keeping your home comfortable. In fact, participants report very little difference in the comfort level of their homes. To keep your home cool on hot days, keep window shades closed, turn on ceiling fans, and refrain from using heat-generating appliances.
