SEMINAR: What the heck is up with the WECC? Expanding the EIM into the Day-Ahead Market: A case study in regional grid integration.
Over the past several years, the California Independent System Operator (CAISO) has explored options for expanding to become a multi-state regional transmission operator, with a footprint extending beyond California into the rest of the WECC (Western US and Canada). One current proposal considers the extension of the CAISO’s Energy Imbalance Market (EIM) from real-time only into the Day Ahead Market (DAM). CAISO sees this as a way to move forward on capturing the efficiencies of regional markets, while maintaining the current voluntary nature of participation in EIM and avoiding some of the political pitfalls associated with a multi-state RTO, such as shared governance, resource planning, and transmission cost allocation.
The presentation will explore some of the important initiatives CAISO is already undertaking to better align itself for eventual EIM expansion: the Day Ahead Market Enhancements (DAME), Flexible Resource Adequacy Criteria and Must Offer Obligation (FRACMOO), GHG accounting, and other market design changes. Drawing on the experience of a variety of subject matter experts within PG&E and CAISO, we will explain the context of each initiative and offer recommendations for moving forward with an eye towards future regional integration.
