The system will be a 6 MW wayside energy storage system (WESS) type installation when complete. The 1st phase is a 2 MW flywheel based energy storage system, consisting of 4 units (500 kW) each capable of producing 2.08 kWh of usable energy.

The goal is to reduce the transit authority's utility bill by absorbing regenerative braking energy and delivering it back when the train accelerates away from the station.

A controller, independent of the WESS, will be utilized to command the WESS to charge and discharge as required.
