Valley Generating Station (VGS), located in the Sun Valley community, is one of four in-basin natural gas fueled power plants. It has a capacity to generate 576 MW, about 6% of the City’s total power generation capacity.
In early 2000, new efficient units were constructed and put into service, and the old units and stacks were taken out of service. The new efficient units can start up in about 10 minutes.
The plant is also home to LADWP’s Health & Safety Office and Joint Safety and Training Programs. Approximately 300 employees report to VGS daily.
LADWP plans to begin demolition of the old generating units, Units 1–4, in 2023. Also included in the demolition plans are structures and systems associated with Units 1-4, the bearing cooling tower foundation, skim pond, and four concrete foundations of previously demolished cooling towers.
Once the project area is cleared, the space will be available land for installation of future renewable energy projects (refer to Future Plans below). The need, timing, and nature of any future projects at VGS will be subject to additional environmental review prior to any approvals or implementation.
Demolition Construction Schedule: Spring 2023 – Fall 2025
Valley Generating Station’s Open-Path Methane Monitoring System
LADWP is currently monitoring methane at VGS using laser-based Boreal GasFinder3-DC monitors. These open-path gas detection monitors continuously monitor and measure gas concentrations over the entire path of the laser, providing real-time ambient methane concentration readings in parts per million (ppm). Weather conditions such as temperature, wind speed, and direction are available on the map as well. Clicking on a data point will display a table of the monitor readings in five-minute averages over the last 24 hours.
Monitoring map works best with Google Chrome and Firefox. Viewing map with Internet Explorer is not recommended.
Prior to the installation of the laser-based Boreal GasFinder3-DC monitors, LADWP’s Corporate Health and Safety Division conducted daily measurements of methane concentrations at VGS using a GASMET infrared gas analyzer (GASMET). The historical GASMET measurements of methane concentrations taken along the perimeter of the plant are posted below.
