Call for Conservation Comes as California ISO Issues Stage Two Electrical Emergency.News Editors/Energy Writers FOLSOM, Calif.--(BUSINESS WIRE)--March 27, 2001 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. ) declared a Stage Two Electrical Emergency today, Tuesday, March 27, 2001, at 1:20 p.m. 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. are low today because imported power from outside the state suddenly dropped by about 1,100 megawatts within a two-hour period this afternoon. Additionally, more than 10,500 megawatts of in-state generation is unavailable due to repairs and some 2,900 megawatts of Qualifying Facilities (QFs), or small independent generators, remain off line. Consumers are asked to step up conservation efforts as the California ISO's job of balancing the supply and demand for power becomes more challenging this afternoon and into the evening peak hours peak hours npl, peak period n → horas fpl punta peak hours peak npl → heures fpl d'affluence or de pointe . Demand across the California ISO Control Area is expected to peak at 29,250 megawatts around 6:00 p.m. this evening. Today's Stage Two Emergency is in effect until 10:00 p.m. With the Stage Two declaration, the California ISO is able to access emergency resources that will help maintain operating reserves. Voluntary load interruption programs have also been activated. A Stage Two Emergency is declared when operating reserves dip below five percent or are expected to within the next two hours. If an operating reserve shortfall of less than one-and-a-half percent is unavoidable, Stage Three will be initiated. Involuntary involuntary adj. or adv. without intent, will, or choice.

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 25,526 circuit mile "electron highway."
