Electricity Storage Applications

Independent System Operator / Market
  • Frequency regulation
  • Spin/non-spin/replacement reserves
  • Ramp
  • Black start
  • Real time energy balancing
  • Energy price arbitrage
  • Resource adequacy
Variable Energy Resource Generation
  • Intermittent resource integration: wind (ramp/voltage support)
  • Intermittent resource integration: photovoltaic (time shift, voltage sag, rapid demand support)
  • Supply firming
Transmission / Distribution
  • Peak shaving: off-to-on peak energy shifting(operational)
  • Transmission peak capacity support (upgrade deferral)
  • Transmission operation (short duration performance, inertia, system reliability)
  • Transmission congestion relief
  • Distribution peak capacity support (upgrade deferral)
  • Distribution operation (Voltage Support/VAR Support)
  • Outage mitigation: micro-grid
Customer Services
  • Time-of-use /demand charge bill management (load shift)
  • Power quality
  • Peak shaving (demand response), Back-up  power

  • QuESt is a free, open source, Python-based application suite for energy storage simulation and analysis. It was developed to bring Sandia energy storage analytics research tools to the desktop. QuESt currently consists of three distinct yet interconnected applications that individually and collectively will help project engineers and researchers evaluate energy storage systems for different use cases.

  • DOE Global Energy Storage Database provides research-grade information on grid-connected energy storage projects.
