Large HVAC systems are often overlooked as a large energy consumer

Lights use only 20% of US electric energy compared to 60 to 70% motors use.

UCR New Grid Research Goals

• Integrate utility scale renewable energy, energy storage,

and EV charging

• Demonstrate the functionality of Smart Grid protocols

• Provide EV charging demand without increased grid loads

• Provide real world Smart Grid test-bed platform

• Evaluate efficiency of energy storage

• Evaluate power quality issues

• Demonstrate battery electric bus transit operating in the

Riverside community
