Unlike chemical batteries that have a limited power output and diminishing cycle lives, flywheel batteries can supply quick surges of power in milliseconds with a reliable 20-30 year lifespan. The small footprint of flywheel batteries makes them easily deployable in any environment. Near Zero’s rapid ramping abilities, high cycle life, and low maintenance make it an ideal supplement to current regulation plant operations. While current installed storage capacity is seeking to compete with fossil fuel regulation plants, Near Zero aims to enable more efficient operation of these plants in a collaborative integration. The ability to provide both energy absorption and generation services at fast ramp rates means that less capacity is needed per regulation event, which enables the plant to increase the number of ancillary service market bids and reduce idle time. While the flywheel is ideal for the initial ramping of supply, Near Zero’s customers will increase asset utilization after the ramping period has ended or when installed flywheel capacity has been discharged.
