Edison International Announces Winners of Edison Challenge Competition

ROSEMEAD, Calif.--(Business Wire)--
Gabrielino High School in San Gabriel and Eastshore Elementary School in Irvine
were selected as first-place winners in the 2009 Edison Challenge, an
environmental science competition. They were among nine teams to take top honors
in the third annual event co-sponsored by Edison International and the
University of Southern California (USC).

"The Edison Challenge is one of the company`s premier community-based
initiatives designed to expand educational opportunities for young people. The
competition continues to inspire students who exhibit a passion for improving
their environment," said Barbara J. Parsky, senior vice president, Corporate
Communications, Edison International.

Sixty-one student-teacher teams submitted original science projects related to
energy and the environment. Hundreds of students, parents and teachers attended
the awards ceremony held at the California Science Center in Los Angeles on
March 28. Bill Nye, popularly known as "Bill Nye The Science Guy," was a special
guest speaker and presented winners with certificates.

Pedro Pizarro, Southern California Edison`s (SCE`s) executive vice president,
power operations, congratulated winners and competition participants. Edison
International is the parent company of electric utility SCE. Pizarro encouraged
students` interest in learning more about protecting the environment and
exploring renewable and alternative sources of energy. "These students realize
the importance and value of scientific innovation. And they clearly were up to
the Edison Challenge with their submissions of many noteworthy projects," he
said.

Gabrielino High School emerged as the first-place winner for the second year in
a row. The team`s project on access to clean water focused on a community-wide
effort to recycle cans and bottles to earn funds to meet their goal of
purchasing 1 million LifeStraws, a portable water purification system for use in
developing countries.

The winning project in the middle school category, which was open to students in
grades six to eight, came from sixth graders at Eastshore Elementary School who
set up a composting site on their campus. Team members and teachers from both
first-place schools will spend a week on Catalina Island and participate in
activities at the USC Wrigley Marine Science Center.

Second-place winners in the competition were Santa Monica High School in Santa
Monica and Sycamore Canyon School in Newbury Park. Students won a four-day trip
to SCE`s Big Creek Hydroelectric Facility in the Sierra Nevada Mountains.

Honorable mentions were awarded to a second team from Gabrielino High School,
Oak Park High School in Oak Park, Pacific Coast High School in Tustin, St. John
the Baptist School in Baldwin Park and San Gabriel Christian School in San
Gabriel. Each of these schools received a laptop computer. Teachers with teams
named as finalists received stipends ranging from $150 to $500.

Edison International partnered with the USC Wrigley Institute for Environmental
Studies, a unit of the USC College of Letters, Arts & Sciences, to create the
Edison Challenge in 2006.

The company has made a $1 million commitment to fund the program over four
years, the largest environmental education grant ever awarded by Edison.
