PG&E Installs 100th Automated Valve Since 2011
Utility Continues System Upgrade; Work Enhances Safety and Integrity of
Natural Gas System
SAN FRANCISCO, Nov. 12, 2013
SAN FRANCISCO, Nov. 12, 2013 /PRNewswire/ --Pacific Gas and Electric Company
(PG&E) today announced that it has automated its 100th valve through the
Company's Pipeline Safety Enhancement Plan (PSEP). The valve automation
program, which began in August 2011, improves PG&E's ability to quickly shut
off the flow of gas in the event of a significant change in pressure. Valves
can be opened or closed from PG&E's newly designed Gas Control Center, instead
of requiring an employee to travel to the site to manually open or close the
"We're working every day toward our goal of becoming the safest, most reliable
gas company in the nation," said Nick Stavropoulos, PG&E's executive vice
president of Gas Operations. "We have a lot more work ahead, but the progress
we've made on installing automated valves – which allow us to stop the flow of
gas immediately to reduce damage during an emergency and allow community
firefighters and police to respond more quickly – is unmatched by any other
utility in the country. I'm exceptionally proud of the crews working
around-the-clock to make it happen."
PG&E's valve automation program is roughly at the halfway point in the
Company's PSEP work plan, which sets a target of automating a total of 212
valves by December 31, 2014. The company's proposed plans are to eventually
install approximately 670 valves, with the majority located in densely
PG&E has also installed a total of 14 automatic shutoff valves where its
transmission pipelines cross major fault lines. In these areas, the shutoff
valves have been designed to close automatically when local sensors at the
valve site detect a possible pipe rupture.
PG&E has instituted new training programs and simulations for control center
employees, emphasizing how to use electronic tools that provide a
comprehensive view of pipeline conditions in real-time and how to evaluate the
potential effects of isolating a pipeline segment.
Valve automation is one component of PG&E's system-improvement efforts, such
as strength testing, in-line inspections, leak patrols, pipeline assessment
and integrity management work.
