Want to estimate your capacity charge before signing up for ComEd’s Hourly Pricing program? Here’s how to calculate it:
1. Go to this page: https://secure.comed.com/MyAccount/MyService/Pages/UsageDataTool.aspx, choose “View Summary Data Online,” and “Add” your ComEd Electric Choice ID. (The ID is located in the “Service Address” section of your bill.)
2. Click “View Usage Data” and it’ll take you to a results screen showing vital stats. The “Capacity PLC” at the top is a calculation that is unique to each customer. (PLC stands for “Peak Load Contribution,” and according to ComEd it represents your expected energy usage during high-demand hours on hot summer afternoons. The PLC is your household electricity usage averaged over 10 system peak periods the previous summer. )
3. Once you find your “Capacity PLC,” you multiply the following four figures:
- The “Capacity PLC” (unique to your account)
- The “scaling factor” (0.97854)
- The “forecast pool requirement” (0.9291)
- The monthly capacity charge rate ($10.11236 per Kilowatt-Month)
4. The product of those four numbers is your capacity charge.
