Slide 20 Energy Storage Projects in Development California 1.3 GW Energy Storage Mandate: Will require multiple large and small installations on both sides of meter. Puerto Rico: Energy storage and backup required on all new wind and solar projects (mostly batteries with diesel backup) Pumped Hydro: FERC has issued preliminary permits to 45 projects for over 43,000 MW. CAES: APEX Bethel (Texas); Chamisa Energy (Texas); PG&E (California). Utility Scale Batteries: Large manufacturers (ABB, GE, Hitachi, Tesla) jumping into the space to compete with smaller already in the space (AES Energy Storage, A123, NGK, Xtreme) Slide 21 Conclusions Change has been tremendous over the past ten years Coal retirements will likely accelerate Renewables, advancements in technology and new technologies will be required to fill the coal gap We all get to be a part of modernizing the nations power supply system Slide 22 Slide 23 Slide 24 Slide 25
