Overview of Presentation

Program background Recent evaluation results that pertain to lighting

– CFL Metering Study– Consumer and supplier lighting market

characterization 2004-2005 program evaluation scope

Single-Family Rebate Program: Lighting component background

Statewide program: PG&G, SDG&E, So Cal Gas, SCE

1998 market transformation initiative - California Residential Lighting and Appliance Program

2001 resource acquisition focus: over 8 million CFL product incentives

2002-2003 Statewide Crosscutting Residential Lighting Program – 4 million CFL product incentives per year

Single-Family Rebate Program: Lighting component background

2004-2005 Statewide Single-Family Retrofit Program – 10 million CFL product incentives per year

(procurement funding accounts for half)– 92% of energy savings goals met through lighting

measures

CFL Metering Study – Objective and Approach

Update CFL energy savings parameters Monitor interior fixtures with CFLs to obtain time-of-

use data– Sample frame: CA residents with CFLs installed,

7 regional strata from San Diego to Chico– Sample size: 375 homes, 891 interior fixtures, 983

CFLs– Monitoring: on/off time and date stamp light

meters; 6-12 months of metering from June 2003 – October 2004

CFL Metering Study – Results

Average hours of use: 2.3 hours per day for interior fixtures

No different from standard lighting usage (based on 1997 HMG study)

Drivers of variation:– Room type– Fixture and control type– CFL vintage

Usage peaks between 8 and 9pm; less than 10% of CFLs operate during summer weekday afternoons

Lighting Market Characterization – Objectives and Approach

2002 Statewide Crosscutting Residential Lighting Program evaluation

Update prior consumer and supplier lighting market characterizations– 1000 residential population surveys (split evenly

between CFL purchaser/non-purchaser) conducted in June 2003

– 50 market actor interviews conducted in June 2003

Lighting Market Characterization – Key Consumer Findings

CFL Awareness, Purchase and Satisfaction

0% 10% 20% 30% 40% 50% 60% 70% 80% 90%

First purchased CFLs since 2001

Purchased CFL torchiere/fixture

Very satisfied with CFLs

Somewhat satisfied with CFLs

Dissatisfied with CFLs

2001

2003

Lighting Market Characterization – Key Supplier Findings Prices have declined – wholesale below $1, retail

between $2-$3 (down from $6 in 2001) – most manufacturers expect prices to decline further

Product diversity has increased – more manufacturers in the market; more designs, shapes and sizes of CFLs; elimination of objectionable features such as oversized bulbs, poor light quality, color rendering

Lighting Market Characterization – Key Supplier Findings, continued

Most products are ENERGY STAR certified Expectations for increased sales in the future due to

declining price and expanding diversity

2004-2005 Single-Family Program Evaluation Scope: Lighting

Consumer CFL survey (CFL purchaser and non-purchasers)

Interviews with lighting retailers, manufacturers and stakeholders

Process evaluation Gross impact assessment (on-site surveys with CFL

purchasers from 2004-2005) CFL Net-to-gross assessment (TBD – may include a

combination of approaches)
