  1. Achievability Issues Conservation Resources Advisory Committee March 12, 2009

  2. Outline • How Achievability is Used & Calculated • Consequences of Assumptions • Interaction with Stock Estimates • Near-Term Penetration Assumptions • Long-Term Penetration Assumptions

  3. How Achievability is Used Conservation Resources Generating Resources Demand Response Imports Load Prices for Fuel, Capital, CO2, Siting, … Similarly Reliable & Available Resource Options Reliability Constraints Time-Dependent Cost & Availability Regional Portfolio Model Develops Plans & Analyzes Cost & Risk for Plans (Plans are Amount and Timing of Resource Decisions)

  4. Consequences: • Near-Term Achievability Penetration • Acts as Practical Limit on Deployment • Impacts Near-Term Targets • Impacts Risk-Mitigation Premium • Higher Cost-Effective Limit for Lost-Opportunity • Long-Term Achievability • Recognizes Can’t Get it All • Retain 85% Max Penetration for 6th Plan • Some Less (HPWH, Solar PV, Set-Top, LED Sign)

  5. How Achievability is Calculated Lost Opportunity Remaining Stock Estimate (or Technical Potential) Achievable Penetration x Non-Lost Opportunity Long-Term Achievable over 20 Years Near-Term Penetration Rates Year by Year Maximum Penetration

  6. Lost-Opportunity & RetrofitStock Estimates Lost-Opportunity Conservation Incremental Cost & Savings Compared to New Baseline Limited to Annual Stock or Unit Availability New Homes, Buildings & Equipment (Driven by Population Growth & Equip Saturation) Replacement Systems & Equipment (Driven by Stock Turnover Rates) Retrofit Conservation Incremental Cost & Savings Compared to Retrofit Baseline Limited to Remaining Stock 2029 Existing Building Stock not addressed by turnover (e.g. weatherization) Systems & Equipment with Slow Turnover Rates (e.g. windows)

  7. Applicable Stock Estimates • Estimates are Measure-Specific & Interactive • Lost-Opportunity • New Stock • Function of Population & Employment & Economy • Replacement Equipment • Function of equipment turnover & remodel rates • Ex: Lighting system turnover rate higher in Retail than Schools • Retrofit • Existing Stock • Minus Demolition & Conversion & Replacement • Plus New & Replacement not addressed as Lost-Opps

  8. Applicable Stock EstimateExample

  9. 5th PlanAchievable Penetration Rates Ramp 15% to Max 85% in 12 Years (Ramp Up 14 MWa to 85 MWa per Year @$100/MWh) Lost-Opportunity Conservation Retrofit Conservation Limited to 120 MWa per Year Based on High Historical Performance Max 85%

  10. Developing 6th Plan Achievable Penetration Rates Two Approaches • Historic Perspective • Recent Regional Performance • Forward-Looking • Build from Bottom Up • Measure-by-Measure Penetration Rates

  11. Historic Perspective Program Performance Pace of Codes & Standards Periodic Survey of Current Stock Forward Looking Considers Character of Measures Implementation Strategies Size & Cost Physical Availability of Equipment Training & Education Requirements Near-Term Achievability

  12. BPA, Utility & NEEA Programs Averaged 150 MWa per year since 2001 Over 200 MWa in 2007 Probably >200 MWa in 2008 At $40-50 /MWh Avoided Costs Codes & Standards One third of Savings since 1991 Large Long-Term Potential Near-Term Impact Limited by New Stock Additions & Turnover Rates Historic Perspective

  13. Forward-Looking Use a Bottom-Up Approach to EstimatePenetration Rates • Estimate Annual Penetration Rates by Measure Bundle • Distinguish Features that Impact Penetration Rate • Complexity of Measures • Delivery Mechanisms & Decision Makers • Current Market Saturation • Equipment & Infrastructure Availability • Subject to Code or Standard • Size & Cost • (Annual Penetration Rate) x (Annual Units) x (Unit Savings) • Then Sum of All Measure-Level Supply Curves by Year & Levelized Cost bin
