1 Seattle City Light Residential Sector Background: Key Facts from the RCCS February 2013 “C”

2  Data from the 2009 Residential Customer Characteristics Survey (RCCS) is summarized below. The RCCS was a mail-out survey to randomly selected residential customers. A total of 2,356 surveys were returned.  Provided below is data relevant to some of the specific questions posed by the Review Panel and additional examples of the data found in the RCCS (available on the web)  and Residential Customer Characteristics Survey

3 Accounts & Building Types  Total Residential Accounts: 100% 360,000 (approx) (Source Annual Report.)  Single-Family 51% 183,600  Multiplex (2- to 4-unit) 11% 39,600  Multifamily (5+ units) 38% 136,800

4 Electric Space Heat Saturation % of living units that use electricity as their primary source of space heat  Single-Family 22%  Multiplex (2- to 4-unit) 54%  Multifamily (5+ units) 85%

5 Water Heat Saturation % of living units that use electricity as their primary source of water heat  Single-Family 54%  Multiplex (2- to 4-unit) 60%  Multifamily (5+ units) 76%

6 Water Heat Saturation: Trends

7 Appliances & Electronics 32% of single-family customers have more than one refrigerator Computers  1.7 per household  12% reported none

8 Lighting: CFLs  Only 10% of single-family customers reported having no CFLs, compared to 24% of multifamily customers.

9 CFLs: Increased Saturation CFL Bulbs Installed: From 2007 CFL Saturation Study & From 2009 Residential Survey

10 Windows & Insulation  Customers reporting having all double pane windows, by space heat source 62% electric 60% natural gas 58% fuel oil  Customers reporting having crawl space/basement ceiling fully insulated, by space heat source 48% electric 36% natural gas 24% fuel oil

11 Electric Energy Use Per Household Average consumption, kWh per year  All Fuels Single Family (SF) 11,165 Multiplex 9,549 Multifamily 7,119  Electric Space Heat Single Family (SF) 16,215 Multiplex 11,896 Multifamily 7,523  SF - electric space heat 16,215  SF - non-electric space heat 9,689

12 Electric Energy Use Per Household Trends

13 Electric Energy Use Per Household All Electric vs Non-Electric ALL-Electric Home (Elec. space + Elec. water) & NON-Electric Home (gas-oil space + gas water)
