  1. WSWC-WGA Water/Energy Workshop April 2, 2013 Incorporating Water into Electricity Planning Doug Larson Executive Director Western Interstate Energy Board

  2. Outline • Western Interconnection electrical context • Value of water info for -- • Electric transmission planners and policy makers • Utility resource plan developers and reviewers • Generation developers

  3. Western Interconnection context • Load growth • Generation resources • Generation retirements and additions • Technology trends • Drivers

  4. Load growth – low and could be lower Compound Annual Growth Rates (Annual Energy, 2010-2032) Source: Lawrence-Berkeley National Laboratory work for SPSC

  5. Geothermal Solar Wind Generating resources – Renewables, coal Renewable Resources Coal demand and resources Coal plant retirements

  6. Generating resources – natural gas 227,386 GWh 234,683 GWh Source: Western Electricity Coordinating Council

  7. Source: Western Electricity Coordinating Council

  8. Factors driving generation procurement decisions • Cost • State policies • Renewable Portfolio Standards • Greenhouse gas emissions • Resource flexibility

  10. 80% Renewables in 2050 Concentrating solar power Geothermal Source: NREL Electricity Futures Study

  11. Operational water consumption factors for electricity generating technologies Caption or heading (if you have one) Recirculating Cooling Dry Cooling Hybrid Cooling Pond Cooling Once-through Cooling No Cooling Required (insert really cool image/supergraphic from your work) Operational water consumption (Gal/MWh) CSP and PV Biopower Nuclear Natural Gas Coal Source: Macknick et al. 2011

  12. Geothermal Concentrating Solar Power

  13. Users of water information: Electric transmission planners Policy makers 1. Transmission planners • WECC planning • Regional planning groups 2. Utility integrated resource plans • Utility resource planners • PUC reviewers of utility resource plans

  14. Users (cont’d) 4. Generation and transmission developers • Screening tool for where regulators and policy makers may have concerns 5. Policy makers • State energy policy offices and PUCs • Federal land management agencies
