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 account number. 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 households 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” (1.00712) The “forecast pool requirement” (0.9380) The monthly capacity charge rate ($8.331 per Kilowatt-Month) 4. The product of those four numbers is your capacity charge.
