SCE and WCEJOINT RATE COMPARISONSAs part of our mutual commitment to better serve customers, Southern California Edison (SCE) andWestern Community Energy (WCE) have jointly created a comparison of our common electric rates,average monthly charges, and generation portfolio contents. To find your specific electric rate,please scroll down. If you are not sure about your specific electric rate, this information can befound on the detailed page of your bill directly beneath the heading that reads "Details of yournew charges."If you have further questions please contact Western Community Energy atwesterncommunityenergy.com or (866) 356-4175 and SCE at sce.com or (800) 974 -2356.DefinitionsGeneration Rate reflects the cost of producing or purchasing electricity to power your home. Thisrate depends on usage, and will vary depending on your service provider and rate plan.SCE Delivery Rate is a charge assessed by SCE to deliver electricity to your home. This ratedepends on usage.Surcharges represents the Cost Responsibility Surcharge (CRS) and Franchise Fee (FF) that areapplicable to Community Choice Aggregation (CCA) customers and SCE customers that elect aGreen Rate. The CRS is a surcharge to recover costs associated with power purchases made onbehalf of customers prior to a customer’s switch to a CCA or SCE Green Rate. The FF recovers taxesowed to a city in exchange for allowing SCE to utilize electrical distribution lines throughout theproperty of the city. SCE acts as the collection agency for the FF surcharge which is levied by citiesand counties for all customers.All comparisons are calculated using SCE’s 2020 static load profiles (typical customer usageprofiles), SCE’s published rates as of February 1, 2021 and WCE's published rates as of March 15,2021.
