Ancillary Services

The components of an ARES Energy Storage System may be deployed to create a robust Ancillary Services system which functions as a LESR (Limited Energy Storage Resource). These high-power short-duration energy storage systems are designed to provide grid-scale Regulation-Up, Regulation-Down, Spinning Reserves, VAR Support and Grid Inertia. The ARES Fast Response Ancillary Service 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 hydro.
 


The ARES Ancillary Service 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 80% they have an extremely fast ramp-rate on the order of seconds to ramp to full power.

"Energy and the environment are inextricably linked. How we get our energy, either through oil, gas, coal or renewables, like wind and solar, not only impacts our environment, but also impacts our quality of life and the future of our planet. ARES energy storage allows us to optimize the use of renewables, decrease our reliance on fossil fuels, reach our goals of environmental sustainability and ultimately reduce impacts that lead to climate change."
