304 <br />WORK STUDY SESSION <br />WS.A. SOUTHERN CALIFORNIA EDISON COMPANY RELATIVE TO <br />ELECTRICAL DEREGULATION AND POSSIBLE POWER OUTAGES <br />Eric Little, representing Southern California Edison (SCE), briefed the <br />Council regarding the reasons for higher load electricity interruption <br />exposure this summer, including load growth, little new generating <br />capacity, and more limited import availability from neighboring states. <br />He further explained that due to the fact that loads in California have <br />grown significantly for several years without adequate generation <br />addition, SCE is predicting increased activation of interruptible programs <br />for this summer and 2001. <br />Mr. Little outlined the following notification procedures used in <br />emergency situations: <br />♦ Alert — a notice issued that, according to the day -ahead forecast, <br />operating reserves will fall below 7% <br />♦ Warning — a notice issued that, according to the hour -ahead <br />forecast, operation reserves will fall below 7% <br />♦ Stage 1 Emergency — a notice issued when reserves fall below 7% in <br />real-time <br />♦ Stage 2 Emergency — a notice issued when reserves fall below 5% in <br />real-time <br />♦ Stage 3 Emergency — a notice issued when reserves fall below 1.5% <br />in real-time <br />Mr. Little noted that there have been no Stage 3 emergencies called this <br />year, however, there have been thirty Stage 1 emergencies, and <br />seventeen Stage 2 emergencies. In a Stage 3 emergency, SCE has as <br />few as ten minutes to shed firm load. <br />Mr. Little also discussed the approved rotating outage plan and <br />explained how it is implemented. He reported that circuits are <br />aggregated into groups of approximately 100MW, and each group has <br />load dispersed throughout service territory, with customers from multiple <br />classes (e.g. residential, commercial, industrial). Service to any one <br />group will be interrupted for about one hour at a time, and interruptions <br />will rotate among groups in sequence. Circuits servicing essential use <br />customers are normally exempt from rotating outages. <br />Following the presentation, Councilmembers asked several questions <br />relating to anticipated outages for this year and next year. <br />Mr. Alan Llorens, representing Edison Carrier Solutions (ECS), a <br />division of Southern California Edison, gave a presentation to the <br />Council explaining the services ECS supplies. He explained that ECS is <br />a "carriers' carrier" and offers fiber optic capacity to all types of carriers. <br />He noted that ECS provides metropolitan access in the central, coastal <br />and southern regions of California, and offers the advantage of being a <br />CITY COUNCIL MINUTES 299 SEPTEMBER 18, 2000 <br />
