Drivers for Electric Energy Storage Solutions in the U.S.
• Managing Increased Wind and PV Penetration on the Grid
• Increased need for Flexible Grid: Ancillary Services / Balancing
• Transission and Distribution Grid Asset Management
– Managing Grid Peaks,T&D Capital Deployment, Outage Mitigation
• High Penetration of Distributed Photovoltaic systems on the Grid
• Enhancing the value of a Smart Grid: Peak Energy Management; End-use energy management.

Opportunities for Energy Storage in the Industrial Sector
Opportunities and Solution Applications:
• Reliability, Back-up, Energy Mgt.
• Power Quality, UPS, Energy Mgt.
• Energy Mgt. and T&D Grid Support
• Energy Mgt. with Renewables
• Energy Mgt. with CHP
Challenges:
• Need low cost storage systems: <<$500 / kW-h installed
• Technical Risk >> Need demostrated solutions
• Options offer Limited Energy >> Hybrid systems with DG
• Business Model >> that maximizies benefits

Challenges: Need Low Cost Storage Systems Energy Storage Application Value Analysis Total Resource Cost Test (TRC) as a Proxy for Allowabe Storage System Cost
Value: $/kW-h of usable energy storage
Caveat: Energy storage systems to address
each application will vary in cost, depending on
size, location, and system power-to-energy ratio.
