Regulation Energy Manangement

The components of an ARES Energy Storage System may also be deployed to create a robust Regulation Energy Management (REM) system which functions as a LESR (Limited Energy Storage Resource).  These systems provide grid-scale Ancillary Services including Regulation-Up, Regulation Down, Spinning Reserves, VAR Support and Grid Inertia.  The ARES Fast Response REM technology bridges the power gap between large scale battery and flywheel installations and far larger pumped-storage hydro -- at a lower life-cycle cost than batteries, a higher energy-to-power ratio than flywheels and a greater efficiency and far faster ramp-rate than pumped-storage.
 
The ARES REM facilities typically utilizes a single uphill track with a central queue of loaded shuttle-trains that travel up and down grade in response to an ISO (Independent System Operator) command to provide Reg-UP or Reg-Down frequency adjustment.  In addition to its high charge / discharge efficiency of 86% it has extremely fast ramp-rate on the order of seconds to ramp to full power.
