Integrated balancing authority areas
The California ISO is holding stakeholder discussions on the ISO's efforts to model the systems of Integrated Balancing Authority Areas (IBAA) under the ISO's Market Redesign and Technology Upgrade (MRTU) program. The ISO MRTU program encompasses a comprehensive overhaul of the ISO electricity markets designed to both enhance reliability and increase the efficient utilization of the transmission system. As part of its larger effort to improve its ability to reliably manage congestion on the transmission system, the ISO has identified needed improvements to how it models and prices transactions to and from IBAA. IBAA are those Balancing Authority Areas or systems that are not part of the ISO Balancing Authority Area but are closely interconnected/integrated with the ISO's system.
- Outcome
  The ISO implemented a single-hub modeling and pricing approach for interchange transactions with the Sacramento Municipal Utility District and Turlock Irrigation District Integrated Balancing Authority Area (IBAA) in order to predict the actual location of resources used to support these interchange transactions. The ISO also implemented tariff provisions to permit alternative pricing under a Market Efficiency Enhancement Agreement (MEEA), if a MEEA signatory provides the ISO with information concerning the location and operation of resources within the IBAA to support its interchange transactions. — Implemented: April 1, 2009; FERC Order: Sept. 19, 2008; Board of Governors approval: May 21-23, 2008
