California ISO Issues Stage Two Electrical Emergency.News Editors FOLSOM, Calif.--(BUSINESS WIRE)--Dec. 12, 2000 The California Independent System Operator (California ISO (1) See ISO speed. (2) (International Organization for Standardization, Geneva, Switzerland, www.iso.ch) An organization that sets international standards, founded in 1946. The U.S. member body is ANSI. ) is declaring a Stage Two Electrical Emergency today, Tuesday, December 12, 2000, after a large power plant in Southern California Southern California, also colloquially known as SoCal, is the southern portion of the U.S. state of California. Centered on the cities of Los Angeles and San Diego, Southern California is home to nearly 24 million people and is the nation's second most populated region, tripped off line. The Stage Two is in effect from 5:10 to 10:00 p.m. Demand across the California ISO Control Area is expected to peak at 33,000 megawatts around 6:00 p.m. tonight. At this time, California ISO will attempt to maintain stability of transmission system without activating voluntary load management programs. However, the California ISO may implement interruptible programs if reserves dip to lower levels. The ISO urges interruptible customers to wait to shed their contracted electrical load If an electric circuit has a well-defined output terminal, the circuit connected to this terminal (or its input impedance) is the load. (The term 'load' may also refer to the power consumed by a circuit; that topic is not discussed here. until specified to do so by their local utility. Interruptible customers, mainly commercial and industrial users, receive a reduced rate in exchange for a commitment to come off line when asked to do so for reliability purposes. The California ISO encourages state residents to continue their energy conservation efforts. Electricity in the state remains in short supply due to cold temperatures in the Northwest that have limited energy imports and approximately 8,500 megawatts worth of in-state power generation that continues to be off line due to planned and unplanned outages. A Stage Two Emergency is declared when 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. 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. A Stage One Emergency, urging Californians to conserve as much energy as possible, was called at 9:30 a.m., and is effective through 10:00 p.m. this evening. 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."
