Demonstrating a Long-duration Flywheel Energy Storage System
The kick-off meeting was held on September 18, 2020. The flywheel technology provider is working on the development, design and construction of the initial unit for this project. The estimated timeframe for the construction and remote testing of this unit is January 31, 2021.
The Recipient will install a practical and low-cost kinetic energy flywheel energy storage system and a solar photovoltaic (PV) array to provide energy to the Viejas Tribal Land. The device consists of a rotating disk that is spun up by a motor to store energy; switching the motor to generation mode causes the disk to spin down and discharge energy to the load. Long duration is achieved by using an innovative technology that employs a large rotor with sufficient inertia to store the required energy with very low loss by employing a proprietary electromagnetic off-loading arrangement. The project will prepare a Multi-Unit Operation Report that describes the layout, instrumentation used, and Measurement and Verification data.
This Agreement will provide Native American Tribes and their communities increased reliability and resiliency services during times of power interruptions caused by weather, grid system failures, or public safety power shutoffs by demonstrating the use of a kinetic energy storage device to provide power during these identified events.
