Interchange scheduling is the import/export of energy across an intertie, both static scheduling and dynamic transfers. Static scheduling represent a fixed amount of energy scheduled to flow for the hour. Dynamic transfers is a general term that applies to either dynamic schedules or pseudo-tie transfers. Learn more about how these types of interchanges schedules operate.
The ISO Department of Market Monitoring (DMM) keeps a close watch on the efficiency and the effectiveness of the California ISO markets, and provides recommendations for market design and operational inputs.
