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
