9 Capturing immense potential in lighting requires maximizing cost-effective CFLs Our proposed portfolio mix corresponds to the technology mix within the energy efficiency potential study findings. It is not out of line to consider the need for a large portion of the portfolio to be in lighting when a consistently large portion of the opportunity potential is in lighting.

10 IOU Portfolios respond to the California Long- Term Energy Efficiency Strategic Plan CLTEESP: Goals. #4 (page 11): “Utilities will begin to phase traditional mass market CFL bulbs promotions and giveaways out of program portfolios and shift focus toward new lighting technologies and other innovative programs that focus on lasting energy savings and improved customer uptake.” Strategies for Goal 4 (page 24)IOU Portfolio Activity 4.1 Drive advances through R&D and competitions The IOU’s Emerging Technology and Rebate Programs work closely with DOE on SSL technology transfer, CALiPER testing, L-Prize, and also with CLTC and PIER projects. 4-2: Create demand for improved lighting products through demonstration projects, marketing efforts, and utility programs The proposed Lighting Market Transformation Program will coordinate across programs to optimize market transformation strategies and practices including improved marketing and program design. It will coordinate with other programs for demonstration projects and technology assessments. 4-3: Continuously strengthen standards. Lighting and Codes & Standards programs will coordinate alignment with AB1109 and other legislation 4-4: Coordinated phase out of Utility incentives for CFLs Gradual - beginning by 2011increasing thereafter as EM&V and market status shows appropriate. 4-5: Ensure environmental safety of CFLs merging lighting solutions Aggressive efforts in limiting mercury in program products, and providing disposal education. Coordination with retailers that house collection sites, and with other agencies.

11 IOU residential replacement lamp transition strategy: CFLs Basic CFLs  Consumer accepted for many applications  Widely available  IOU programs have reduced focus on Basic CFLs: Smaller percentage of portfolio compared to previous years Promotional Focus Away From Basic CFLs Split Upstream Lighting into two programs, Basic & Advanced to give visibility to reduction in basic CFL presence  IOUs can leverage upstream relationships for future product development  For many consumers, a cost-effective gateway to other energy efficiency purchases  For California, a cost-effective way to achieve GHG reductions  Strategic Plan Indicates Phase Out of Promotion Should Begin by 2011, Increase Thereafter 2009 Phase Out of Basic CFL Incentives 2020

12 IOU residential replacement lamp transition strategy: Specialty CFLs Super Lamp LEDs Specialty CFLs Increase Quality –Selectivity of products for allocations by quality (relative to incandescent/halogen performance) Increase Consumer Familiarity –Education and promotion, paid from the applicable program’s budgets. Increase Market Acceptance –Manufacturer signage requirements to include features and benefits of specialty products

13 IOU residential replacement lamp transition strategy: Super Lamp Super Lamp Product does not yet exist; IOU’s working with manufacturers to develop IOUs incentives planned Goals, aimed at removing qualitative barriers to adoption, include improved start up, improved CRI, etc. Goals are technology neutral; LEDs are acceptable, as are induction, cold cathode, or other light sources. CFLs LEDs Specialty CFLs

14 IOU residential replacement lamp transition strategy: LEDs LEDs IOUs, DOE, and CEE engaged to avoid CFL mistakes Most products tested in DOE CALiPER program do not yet meet claims or match incumbent performance Incentives upon program rollout for niche LEDs that are market ready. Energy Star Spec expected in 2009 Cost for Energy Star products likely to be very high: –Manufacturer estimates $200+ for LED vs. $10 for a Par 38 lamp; As eligible market-ready LEDs become available, IOUs will grant allocations and begin to promote ET strategies include: –Work with DOE, CEE –Prepare market: Fact sheets/field placements Super Lamp Specialty CFLs CFLs

15 Transition timing and incentive levels will be guided by new product availability and EM&V studies ProductTimingIncentives Basic Bare Spiral Non- dimmable CFLs Gradual incentive phase out begins by between 2010 and 2011, monitoring snap back to incandescent Gradual decrease in percentage of total incentive budget, as guided by ongoing EM&V and market entry of new products Specialty CFLs Incentives for eligible lamps Incentives now available; Eligible lamps could account for 38% of upstream lighting incentives by 2011 Super Lamps Roll Out Anticipated Complete By Mid 2011 Introductory Incentive High. Reduce When Costs Drop. LEDsAs Ready For Market and Qualified Through Energy Star Not yet determined. Need balance between driving sales and cost-effectiveness.
