 As battery technologies progress it becomes
more economical to use larger batteries
 More applications and duty cycles can be
electrified
 Requires more infrastructure and power to
deliver the energy

 Siting decision factors:
Can you locate near power?
Cost to bring power?
 Energy Management Tools:
Distributed Generation
Energy Storage
Smart Charging
 Microgrids
The Grid has enough energy but not always in the right places.

 Storage with & without wheels
 Access to more value streams
the closer to the grid edge
 Multiple roles & Network Effect
 Variable Renewables Energy
Integration
 Geographic, Locational Value
 Autonomous Vehicles, Car Share
Behind the Meter Energy Storage
