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.
