Update on CAISO / PacifiCorpEnergy Imbalance Market
Presentation to WECC Market Interface Committee
March 25, 2014
Jim Price, Senior Advisor, Market Development & Analysis, CAISO
What is the Energy Imbalance Market?
• 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.
