February 1, 2012 - San Onofre Nuclear Generating Station Operators Assessing Leak and Shutdown of Reactor Unit

Media Contact: Media Relations, (626) 302-2255

ROSEMEAD, Calif., Feb. 1, 2012 � Southern California Edison (SCE), operator of the San Onofre Nuclear Generating Station, continues to plan for the repair of the steam generator tube leak in Unit 3 following a precautionary shutdown Tuesday. Sensitive monitoring instruments at Unit 3 continue to show no change in radiation levels that would be detectable off-site.

Operators responded quickly yesterday to indications of a steam generator tube leak based on readings from highly sensitive instruments designed to detect this condition, and in time to take action to prevent any potential change in detectable radiation exposure outside the plant boundary. Operators safely shut the plant down and isolated the component that contained the leaking tube within four hours of detecting the indications.

Currently, operators are cooling down Unit 3 and reducing pressure in the plant, which is the method to stop the tube from leaking. They are meticulously following prescribed procedures written specifically for addressing a tube leak condition.

"There was no threat then, nor is there now any danger to the public or to plant workers," said Pete Dietrich, senior vice president and Chief Nuclear Officer for Southern California Edison. "Our operators performed exactly as they are trained to perform and took prompt action to ensure we did not create a situation involving any challenge to the health and safety of the public," Dietrich said.

Unit 2 is currently offline for a planned maintenance, refueling and technology upgrade outage. Service will not be affected; Southern California Edison has ample reserve power to meet customer needs.

San Onofre Nuclear Generating Station Operators Assessing Leak and Shutdown of Reactor Unit

January 31, 2012 - San Onofre Nuclear Generating Station Operators Perform Precautionary Shutdown of Reactor Unit

Media Contact: Gil Alexander, (626) 302-2255

ROSEMEAD, Calif., Jan. 31, 2012 � Southern California Edison (SCE), operator of the San Onofre Nuclear Generating Station, has begun a precautionary shutdown of Unit 3 because sensors installed for this purpose detected a possible leak in one of the unit�s steam generator tubes.

The potential leak poses no imminent danger to the public or plant workers. There has been no release to the atmosphere. San Onofre personnel will evaluate the cause of the leak and the steps required to repair it and resume operations.

Unit 2 is currently offline for a planned maintenance, refueling and technology upgrade outage. Southern California Edison has ample reserve power to meet customer needs while Unit 3 is offline.

The Nuclear Regulatory Commission was immediately informed of this development.

January 27, 2012 - Strong Winds Expected in Southern California Communities, Utility Crews Prepared to Respond to Possible Outages

Media Contact: (626) 302-2255

ROSEMEAD, Calif., Jan. 27, 2012 � High winds are forecast for many areas of Southern California and red flag warnings will be in effect today through Saturday evening. Southern California Edison (SCE) reminds its customers outages might occur and to never approach or touch downed power lines. If you see a downed line or dangling wire � even if it appears not to be live � don�t touch or approach it and call 911 immediately.

Santa Ana wind conditions are expected to peak tonight and early Saturday. The National Weather Service is forecasting strong winds in Los Angeles, San Bernardino, Riverside, Orange, Santa Barbara and Ventura counties.

SCE is closely monitoring the conditions and has crews on standby to respond immediately, should there be outages. If outages occur, customers can get the latest information at www.sce.com, www.Twitter.com/SoCalEdison and www.facebook.com/socaledison.

Customers on the medical baseline program, who require medical equipment powered by electricity, can get information by calling these numbers:

English: (800) 684-8123
Spanish: (800) 441-2233
Chinese: (800) 843-8343
Korean: (800) 628-3061
Vietnamese: (800) 327-3031
Cambodian: (800) 843-1309
TTY (800) 352-8580

Customer safety is a top priority for SCE. Because of the high fire danger, do not use candles for lighting as they pose a significant fire hazard. Also, check emergency supplies to be sure you have a battery-operated radio, a flashlight and fresh, extra batteries.

SCE encourages customers to keep these other safety tips in mind:

Watch for traffic signals that may be out. Approach those intersections as four-way stops.
Do not use any equipment inside that is designed for outdoor heating or outdoor cooking. Such equipment can emit carbon monoxide and other toxic gases.
To prevent loss of data and/or damage to your sensitive electronic equipment, consider surge suppressors or shut off or disconnect all such equipment during the windstorm or until power has been restored to protect against electrical events that can accompany outages or that can occur during service restoration.
If you use a generator, place it outdoors and plug individual appliances directly into the generator, using a heavy-duty extension cord. Connecting generators directly to household circuits creates �backfeed,� which is dangerous to repair crews.
Leave the doors of your refrigerator and freezer closed to keep your food as fresh as possible. Place blocks of ice inside to help keep food cold. Check food carefully for signs of spoilage.
Check on your neighbors to make sure everyone is safe.

SANTA ANA, Calif., Jan. 23, 2012 -- Edison Mission Group (EMG), a subsidiary of Edison International (NYSE:EIX), has announced commissioning of the Pinnacle Wind Farm at NewPage located on Green Mountain, near the Maryland-West Virginia border.

The 23-turbine wind farm has a maximum generating capacity of 55 megawatts (MW), enough electricity to meet the average needs of about 14,000 homes. The project sells two-thirds of its output to the Maryland Department of General Services and one-third to the University of Maryland system. It is the second project to begin commercial operation under the Generating Clean Horizons program of the Maryland Energy Administration (MEA).

Through the Generating Clean Horizons program, the state and university system of Maryland have committed to purchase 78 MW of energy produced from two wind farms and one solar installation over 20 years. According to the MEA, Generating Clean Horizons powers 16 percent of the state�s electricity demand through renewable sources.

�We are excited to help lead the development of clean energy and are especially pleased that our Pinnacle project is able to advance the state of Maryland�s clean energy goals,� said Pedro Pizarro, president of EMG, whose operating companies are among the leading developers and operators of wind energy projects in the U.S.
