4. 3 Renewable Energy Breakdown

5. RPS by technology LADWP Energy Mix Note that Coal is being reduced from 39% to 27% as shown Projected 2020 Resource Mix

6. PROJECTS IN SERVICE PROJECTS PLANNED & UNDER CONST. DEFICIT GOAL 33% RPS Deficit without New Solar Projects

7. RPS Project Selection Principles Geographic Diversity of projects is important Maximize use of existing LADWP transmission & land Maintain options/flexibility Regionally “cluster” renewable projects to achieve efficient operation and maintenance Ownership of projects using proven technology

8. Future LADWP Energy Projects Solar: In-Basin Solar (on-going) Pine Tree Solar (Dec 2011) -10 MW Adelanto Solar (Feb 2012) – 10 MW Owens Valley (2018) - 200 MW Wind: Pine Canyon (2018) – 120 MW Geothermal: Imperial County (2017) – 50 MW Power Purchase Agreements: Over 200 responses to Jan 2011 RFP Solar, Geothermal. Wind, and Biogas Transmission Upgrades: Barren Ridge Renewable Energy T/L (2016/17)
