California’s subhourly wholesale electricity market opens to systems outside its footprint

On October 1, the grid operator for most of California will begin simulating the balancing of subhourly electricity supply and demand for PacifiCorp's electric service areas in the western United States through an energy imbalance market. After a month of simulation, financially binding operations will begin on November 1. By adding its generation resources to the resource pool of the California ISO to meet subhourly electricity imbalances, PacifiCorp anticipates enhanced reliability and cost savings, particularly in the face of higher levels of renewable energy generation in the West.
