Ventura Compressor Modernization Project


  • Compressor Map
    Project Overview
    Being part of the Ventura community is something SoCalGas takes pride in, and we always strive to be a good neighbor. As we continue delivering natural gas in a safe, reliable, and affordable manner, SoCalGas has renewed our commitment to enhanced transparency with the community regarding the operation of our Ventura Compressor Station and the planned Modernization Project.


The Ventura Compressor Station is the only compressor station on the SoCalGas coastal transmission system and has been operating safely and reliably for decades. SoCalGas plans to replace and modernize the 40-year-old compressors at the Ventura Compressor Station with new units that can accommodate day-to-day changes in the use of the station. As more renewable energy comes online, the need for this system increases to help support reliability and resiliency, along with an integrated electric and gas system. The facility currently supplies natural gas for heat, hot water and other uses to over a quarter of a million customers in Ventura and the Central Coast, including residential, business, industrial, and agricultural customers.

Feasibility Analysis

We completed the feasibility study, consistent with the CPUC’s request to evaluate potential alternatives to the planned Ventura Compressor Station Modernization Project, including alternative site locations and equipment configurations. We appreciated receiving your feedback and comments on the Ventura Compressor Station Modernization Project during our community workshops and town hall meetings last year and incorporated your suggestions into the analysis. Below are links to the Feasibility Analysis and Executive Summary. We will continue to hold true to our commitment to remain clear and transparent regarding the operation of the Ventura Compressor Station and the planned Modernization Project.

Frequently Asked Questions

Methane Detector Project

SoCalGas will install fence-line methane monitoring equipment along the perimeter of the Ventura Compressor Station beginning the week of July 5, 2022. The system will continuously monitor for methane to provide additional transparency about operations at the facility.  

The City of Ventura approved the construction permits for installation activities, which are anticipated to take approximately 9 to 12 weeks to complete and will occur between 7 a.m. and 6 p.m. Monday through Friday. After being installed, calibrated, and tested, the fence-line methane monitoring system will monitor methane on all four sides of the station and the data will be shared on   

Soil Remediation Project 

SoCalGas recently informed the CPUC and the Department of Toxic Substance Control (DTSC) that we plan to move forward with our soil remediation project. SoCalGas provided public notice on June 23, 2022, that this work would begin no sooner than July 23, 2022. The project will remove impacted soil associated with historical industrial uses on the property. This work will be performed in compliance with applicable environmental, safety and public health laws and includes on-site air monitoring. Prior to remediating the soil, lead paint and asbestos will be removed at the existing office and warehouse by certified contractors and inspectors. The existing buildings will then be demolished, and the soil remediation will commence thereafter. The project could take up to 30 weeks to complete.  

Additional Background on Safety Systems

The Ventura Compressor Station has been operating safely and reliably since 1923. The facility is equipped with a series of safety systems that protect our employees, contractors, and the neighboring community. All of these systems are routinely checked and verified for proper operations. Safety systems include:

  • Emergency shutdown system that is designed to depressurize (within three minutes) and isolate the station from all energy sources if fire or methane leaks are detected inside the compressor station.
  • Pressure safety valves (relief valves) are installed on all gas-carrying pipes to prevent over pressurization.
  • Methane detection sensors and fire detection systems are installed in the compressor building to closely monitor for methane leaks and sparks.
  • The compressor units are also equipped with vibration sensors that will trigger unit shutdown if excessive vibration is detected in order to prevent mechanical damage.
  • The station is staffed by onsite employees who maintain the station, and the station is monitored 24-hours a day, seven days a week.
