Energy Efficiency in California

Energy Efficiency - Utility Leadership for Over 30 Years_________________________________________________________________________________________________________________________________________________________

• PG&E Customers since 1976– saved enough annual electricity to power over 20 million homes– saved enough annual natural gas to heat 22 million homes– avoided the emission of more than 135 million tons of C02

• Leadership, advice and guidance to help manage energy use


October 13, 2008 5


Energy Efficiency - California’s Highest Priority Resource_________________________________________________________________________________________________________________________________________________________

• “Loading order” to meet new demand1. Energy efficiency and demand response

2. Renewable energy

3. Clean fossil-fueled distributed generation and clean fossil-fueledcentral-station generation

Energy Efficiency Program Funding_________________________________________________________________________________________________________________________________________________________

• 2009 - 2011 Three Year Program Cycle:

$3.7 Billion for efficiency


October 13, 2008 8


California Legislation_________________________________________________________________________________________________________________________________________________________

• Assembly Bill (AB) 1109 - California Lighting Efficiency and Toxics Reduction Act

– Goals: By 2018, reduce lighting energy consumption• By 50% for Residential Indoor• By 25% for Commercial and Outdoor


October 13, 2008 9


• Energy Efficiency and Climate Change– Will be drivers for adoption of emerging energy efficient

technologies, including outdoor lighting

Emerging Technologies: Opportunities for Outdoor Lighting

Street and Area Lighting Energy Use_________________________________________________________________________________________________________________________________________________________

• National Consumption1

– 178,000 GWh/yr– 23% of annual lighting consumption– Over 16 million homes2

• Street and Area Lights– National: 133 million luminaires

• PG&E Streetlights: 730,000

Energy Savings and Carbon Reduction_________________________________________________________________________________________________________________________________________________________

• Street and Area Lighting1

– 44,700 GWh/yr estimated savingsnationwide1

– Avoid output from seven 1,000 MWcoal-fired power plants1

– 30 million tons/yr CO2 reduced2

Maintenance and Operation Cost Savings_________________________________________________________________________________________________________________________________________________________

• Longer life– Reduced replacement part cost– Reduced field labor– Reduced hazardous waste disposal cost– Reduced administration cost

• Difficult to quantify– Range from $12/year/fixture - over $100/year/fixture

• Opportunities

• Issues– Design practices, incentives, rate schedules

Emerging Technologies: Issues for Outdoor Lighting

Outdoor Lighting Practices_________________________________________________________________________________________________________________________________________________________

• Current practices do not fully address the different attributesof various lighting sources

• Outdoor Lighting Symposium - September 2008– Areas identified for research and development

• Lumen effectiveness multipliers• Best practices• Adaptive standards• Development of visibility metrics• Additional demonstrations


October 13, 2008 18


Incentive Program Development Challenges_________________________________________________________________________________________________________________________________________________________

• Variable Product Quality• High Cost - Marginal Total Resource Cost (TRC)• Setting Incentive Levels• Rapid Technology Advancements• Customer Education


October 13, 2008 19


Standards Based Incentive Approach_________________________________________________________________________________________________________________________________________________________

• Benefits– Maintain high quality– Support DOE Energy Star and industry-standard test methods– Send signal to the market that quality matters

• Results– Higher customer satisfaction– Persistent, reliable energy savings


October 13, 2008 20


Proposed DOE Energy Star Category A Criteria_________________________________________________________________________________________________________________________________________________________

• Street and Area Lighting– Minimum Light Output: 2,300 lumens (initial)– Zonal Lumen Density Requirement: 100% below 90o, Dark Sky

compliant– Beam Uniformity: Varies by luminaire classification type– Minimum Luminaire Efficacy: 50 lumens/watt

October 13, 2008 21


Street Light Rate Schedules_________________________________________________________________________________________________________________________________________________________

• Issues– Street Lights are typically unmetered– Rate based on type of lamp, calculated energy use– No “standard” products– Lengthy regulatory process– What about controlled streetlights?


October 13, 2008 22


Street Light Rate Schedules_________________________________________________________________________________________________________________________________________________________

• Proposed Solutions– Develop “wattage categories”

– Validate energy consumption based on IESNA LM-79 test– Adjust controlled streetlights based on confirmed operating

schedule

$????60.0 - 64.9

$????55.0 - 59.9

$????50.0 - 54.9
