Southern California Edison Responds to Area Fires

ROSEMEAD, Calif.–(BUSINESS WIRE)–Multiple wind-driven wildfires moving through Southern California are
affecting customers and electric service in Southern California Edison’s
service territory.

Prior to the fires, based on forecasted winds and red flag warnings, SCE
mobilized a full emergency response team, pre-staged critical field
personnel and implemented measures to mitigate impacts of high winds and
potential fires. Driven by public safety concerns for customers in
extremely high-wind areas, these measures included a preventative power
shutoff to the Idyllwild area in Riverside County for portions of the
period from December 7th through December 8th.

The Thomas fire has significantly affected customers in Ventura and
Santa Barbara counties and is continuing to threaten the transmission
lines in the area. The fire has intermittently interrupted service for
the Santa Barbara area, at times leaving more than 85,000 customers
without service. SCE is coordinating its emergency efforts with federal,
state, county and local officials. SCE crews are continuing to monitor
the situation and have developed contingency plans that include the use
of temporary generators and re-routing of power.

Restoration of equipment is important in order to restore and maintain
service for customers. Restoration of SCE equipment damaged by the
Liberty fire is complete. Restoration of equipment damaged in the Rye
and Creek fires is targeted for completion by December 12th,
contingent on fire and weather conditions. Where safe, restoration is
ongoing in the Thomas fire area, although this fire remains largely
uncontained. All restoration work is being conducted in close
coordination with fire agencies and other first responders to ensure
public and employee safety. SCE teams will continue to assess damage and
make repairs when safe to do so.

SCE personnel have completed damage assessments in a majority of the
Thomas fire areas where access has been granted and in all of the areas
impacted by the Creek and Rye fires. More than 600 SCE workers have been
deployed on the wildfires, including those repairing fire-damaged
equipment (including damaged poles, wires and insulators), setting
poles, installing electrical equipment and stringing wire to restore
power to customers as quickly and safely as possible. As of today, in
the areas that have been inspected, crews have replaced over 300 of the
more than 500 poles that were destroyed, while damage assessment
continues in the Thomas fire area. The company continues conducting
inspections on the ground and using aerial resources.

Edison International is supporting customers impacted by the fires
through a $250,000 donation to the Southern California Wildfire Fund
through the United Way of Greater Los Angeles. In addition, the company
has provided a $40,000 grant to United Way Ventura County for local
support of its outreach to fire victims. SCE is working with known
medically sensitive customers in the areas impacted by the fires,
including providing temporary generators and other support for critical
care customer without power. The company also continues to work with
affected customers to offer flexible payment arrangements or bill
forgiveness depending upon the situation.

The causes of the wildfires are being investigated by CAL FIRE, other
fire agencies and the California Public Utilities Commission. The
investigations now include locations beyond those identified last week
as the apparent origin of these fires. SCE believes the investigations
now include the possible role of its facilities. SCE continues to
cooperate with the investigations. The wildfire investigations may take
a considerable amount of time to complete. SCE will provide updated
information as circumstances warrant.

Safety around Power during Outages

• Stay away from downed wires. If you see a wire down, call 911.
• If you are using generators, do not run them inside your home. There
  is a danger of carbon monoxide poisoning from generators used indoors.
  Plug appliances directly into the generator, do not plug the generator
  into the 220v line, as this could cause backfeed which could
  electrocute crews working on the lines.
• Stay away from crews working in or around lines or vehicles. They are
  working as quickly as possible and they should not be distracted from
  this dangerous work.
