Operating reserves In power systems, the operating reserve is the generating capacity available to the system operator within a short interval of time to meet demand in case a generator is lost or there is another disruption to the supply. the ISO maintains to ensure reliability of the Grid were impacted after imported power from the Northwest was reduced by approximately 1,600 megawatts from yesterday. Only 1,500 megawatts are currently flowing into California from Oregon, Washington and Canada vs. approximately 2,700 megawatts yesterday. Megawatt-savings through conservation are extremely helpful to the California ISO's efforts to manage the state's electricity grid during these instances of short supply. Californians are encouraged to increase their conservation efforts as much as possible today. Demand across the California ISO Control Area is expected to peak at 28,675 megawatts around 6:00 p.m. this evening.

With the Stage Two declaration, the California ISO is able to access emergency resources that will help maintain operating reserves today. At this time, the ISO has not requested that the utilities' voluntary interruptible customers, mainly commercial and industrial users, come off line. A Stage Two Emergency is declared when operating reserves dip below five percent or are expected to within the next two hours.

The California ISO's Electrical Emergency Plan (EEP EEP Export Enhancement Program EEP Ecosystem Enhancement Program EEP Early Entrance Program (University of Washington) EEP Equal Error Protection EEP Einstein Equivalence Principle EEP Emergency Evacuation Plan ) is part of the State's enhanced reliability standards created by landmark legislation Assembly Bill 1890, which restructured California's electricity industry. The California ISO is charged with managing the flow of electricity along the long-distance, high-voltage power lines that make up the bulk of California's transmission system. The not-for-profit public-benefit corporation assumed the responsibility in March, 1998, when California opened its energy markets to competition and the state's investor-owned utilities turned their private transmission power lines over to the California ISO to manage. The mission of the California ISO is to safeguard the reliable delivery of electricity, facilitate markets and ensure equal access to a 12,500 circuit mile "electron highway."
