SAN FRANCISCO, Calif.— Pacific Gas and Electric Company (PG&E) has submitted to the California Public Utilities Commission (CPUC) its final report on the company’s extensive multi-year Pipeline Safety Enhancement Plan (PSEP). This report details the hundreds of projects undertaken by PG&E to implement safety, operational reliability and environmentally-focused upgrades and enhancements to its natural gas transmission pipeline system.

The PSEP was formally submitted to the CPUC on August 26, 2011, with the goal of enhancing safety and improving operations of the gas transmission pipeline system, which now totals approximately 6,600 miles.

The last PSEP project became operational in November 2018.

“This final report outlines a number of important milestones in our commitment to gas safety, reliability, affordability and environmental stewardship. While we have completed the specified enhancements and upgrade projects as they relate to PSEP, our commitment to safety work is ongoing. We are continuously looking to identify new ways to make our extensive natural gas system the safest in the nation, because when it comes to safety, our work is never done,” said PG&E Gas Operations Senior Vice President Jesus Soto.

Upgrades to the gas transmission pipeline system under the PSEP project include:
