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)
