Energy StorageGrid-tied Megawatt Storage for Wind Energy
• First full utility-scale deployment in 2009 1.0 MWh storage coupled with 30 MW wind farm
on a 80-200 MW grid• Energy storage platform capable of:
Transmission Curtailment Ramp Control / Time Shifting Grid Frequency / Voltage Regulation Support
• National Instruments platforms used for: Battery management and monitoring High speed / subcycle supervisory control

Inverter Control TechnologyDesign, prototype and deploy next generation inverter control system
SB-RIO General Purpose Inverter Controller (GPIC)
• California Energy Commission identified that over 80% of their solar farms’ failures are related to inverters
• Improve efficiency and reliability• Fast HIL inverter simulator with loop rates over 3M/sec• Read inputs, calculate simulation, update outputs
