20. UCSD’s Perspective on Energy
Storage
Energy storage is the missing link and enabler technology
UCSD is pursuing 4 energy storage projects
• Distributed Energy Storage
• Frequency Regulation
• Optimized Thermal Energy Storage
• Grid to Vehicle Integration
UCSD has issued a $3.4M RFP for 2 MW
/ 10 MWH of Advanced Energy Storage,
and bids are due December 15, 2009
The result will be a smart microgrid that
is nationally replicable and scalable
