SAN FRANCISCO--(BUSINESS WIRE)--
Pacific Gas and Electric Company (PG&E) delivered excellent electric
reliability in 2016 with the average customer experiencing one outage
during the year. PG&E’s sizable investment in its electric
infrastructure and its robust commitment to integrating innovative
technology continues to pay dividends for its customers.
In 2016, the average duration of power outages for a PG&E customer was
109 minutes. That was up slightly from 96 minutes in 2015, but still
represented the second-lowest total in history and reflects a 35 percent
improvement over the past decade. The slight decline in year-over-year
reliability can mostly be attributed to stormy El Nino weather early in
the year.
“It’s our job to provide safe and reliable power to our customers, and
I’m proud to say that that is exactly what the men and women of PG&E
delivered in 2016. The hard work of our employees coupled with the
investments we continue to make to create a smarter, more reliable grid
benefit all of us,” said Pat Hogan, senior vice president, PG&E Electric
Operations.
What’s behind the solid electric reliability performance in 2016? The
integration of advanced communications and control technologies
throughout the electric grid continues to enhance the resiliency of the
system and helps identify and restore power outages more quickly. In the
last five years, PG&E has invested $15 billion to enhance and harden its
electric transmission and distribution system assets. A wide range of
factors, from the operation of new distribution control centers to the
building of a smarter energy infrastructure to advances in forecasting
and emergency planning, all contributed to reliability progress.
New Distribution Control Centers
Since 2014, PG&E has opened three state-of-the-art electric distribution
control centers that manage more than 140,000 miles of electric
distribution power lines throughout Northern and Central California. The
third of these – in Rocklin in Placer County – opened in 2016. These
facilities are the nerve centers of the grid that delivers energy to the
homes and businesses of more than 16 million Californians. The Rocklin,
Fresno and Concord centers have enhanced electric reliability for PG&E
customers while incorporating clean, renewable energy into the grid.
Smart Grid
PG&E continues to install advanced automated technology on power lines
throughout its service area. This technology can automatically
“self-heal” the grid by re-routing the flow of electricity around a
damaged power line and effectively restore power to the majority of
impacted customers within minutes. These systems have been installed on
more than 25 percent of PG&E’s electrical distribution circuits, helping
the company avoid more than 160 million customer outage minutes and
saving more than 1.6 million customers from a sustained outage since the
program began in 2012. Other advances, such as line sensors that help
pinpoint the specific location of an outage, continue to be integrated
into the system.
Advance Forecasting
PG&E’s meteorology team has developed a Storm Outage Prediction Model
(SOPP) that incorporates real-time weather forecasts, historic data and
system knowledge to accurately show where and when storm impacts will be
most severe. This model enables the company to pre-stage crews and
equipment as storms approach to enable rapid response to outages.
