What is “imbalance” and how does EIM help
• Balancing authorities (BA) start the hour with matched generation and forecasted load.
• Imbalances are load and generation deviations that occur within hour.
• Most BAs must procure extra reserves and dispatch manually to meet these imbalances.
• Five minute dispatch: – Finds least cost resources to solve imbalance, – Avoids congestion – Dispatches them automatically

EIM preserves participants’ autonomy and current practices

• Balancing authorities retain reliability compliance obligations
• Balancing authorities balance and provide their own ancillary services
• Balancing authorities can trade bilaterally
• Participants retain all physical scheduling rights

Stakeholder Process – Design evolution • Transmission usage fees – no charge initially between PAC
and ISO
• GHG proposal – achieves compliance and addresses load outside California
• EIM leverages full capability of Order 764 enhancements
• Resource sufficiency evaluation addresses “leaning” concerns – Under-scheduling penalty – Infeasible schedules isolated – Flexible ramping requirement ensures entity can meet
dispatch requirements
• Real-time unit commitment added

Benefits of an Energy Imbalance Market
• Enhances the ability to integrate renewable resources by dispatching every five minutes.
• Provides reliability and economic benefits to all participants.
– Enhances reliability through real-time visibility across all balancing authorities
– Captures benefits of geographical diversity of load and resources
– Balances in real-time with least cost generation

EIM Governance proposal • The goal is to provide a meaningful voice to in-state and
out-of-state entities during the implementation of EIM and the design of an “Independent EIM Structure.”
• The “Transitional Committee”, scheduled to be appointed by the board in the spring of 2014, will be an advisory committee of the Board.
• The Transitional Committee will work on developing recommendations on independent EIM structure over the next few years and will go to the Board for its consideration
