Strategic Investment in Energy Storage
• World class manufacturing facility located at GE campus in Schenectady, New York
• Production commenced in September 2011
• Grand opening in July 2012
• 300+ employees / 220,000 ft2
• Footprint for 1+ GWh / year production at full capacity
• Capacity added as market dictates

Q2 2013
Jobs for Durathon Energy Storage 9. Provide supply / demand balancing for
microgrids
10. Provide grid quality functions
11. Maximize PV to get lower cost than
existing DG solutions
12. Lower cost for end use through lower
demand charge
13. Lower cost of electricity for end user by
maximizing PV self consumption
14. Power backup for end user
1. Meet grid connection requirements to
connect RES plant
2. Increase plant revenue by capturing
more value
3. Increase plant revenue by avoiding
load value of curtailment
4. Extend life of aging substations
5. Lower cost by installing smaller
transformers
6. Provide network power quality
functionality
7. Provide temporary back up
power for substations
8. Provide black start / restart to
substations

Distributed Intelligent Power Network
• In expanding deregulated markets, transactive control of distributed energy assets is how the future grid will be driven
• Storage is the enabler for
this new paradigm in edge energy management
• The ability to integrate,
aggregate, and intelligently control tens of millions of endpoints requires a revolutionary management platform
