CA Needs Energy Storage

Unlike Batteries, Incremental Cost to Store More is Minimal (MW vs MWh) Storage System Capital Cost 600 500 400 P2G2P - Existing Generation $/kWh 300 Li-Ion Battery 200 100 0 5 15 25 35 45 55 65 75 Discharge Time (h) 5

P2G Provides Seasonal Storage

P2G Creates Flexibility 7
