Leverages existing CAISO market, for financial benefits at low cost & with low risk –Starting from forecasted load and balanced generation, EIM’s security constrained unit commitment and economic dispatch: Automatically dispatch least cost resources to solve imbalances, Avoid congestion. Enhances reliability with improved situational awareness Captures geographical diversity of load and resources Potentially reduces flexible reserve requirements Provides easy entry/exit for EIM participation –No critical mass – each participant enters when they are ready –New participants pay their way through a front end charge based on size, and ongoing charges based on participation.
