SchlumbergerSema, a business unit of Schlumberger Limited, today announced it has signed a contract with the Los Angeles Department of Water and Power (LADWP) to furnish consulting, integration services and equipment to automate existing electrical substations.

The $56 million contract represents one of the world’s largest substation automation projects, and includes retrofit of 179 existing substations and supply of two development/testing systems and a training simulator system. As lead aggregator, SchlumbergerSema will work together with technology provider Tasnet and subcontracted local minority business enterprises to provide all the services related to the system design, development, procurement, assembly and testing. SchlumbergerSema will also assist with the installation and commissioning of each system, and will provide training services for system operation and maintenance. Deployment of the system is scheduled to begin in late 2002, and is expected to take up to five years to complete.

According to Jack Waizenegger, LADWP’s project manager, automating their substations utilizing the SchlumbergerSema solution will provide the following benefits:

  • Maintain control system integrity by improving the Supervisory Control and Data Acquisition (SCADA)/Remote Terminal Unit (RTU) availability rate and providing expansion capacity
  • Improve operating and maintenance efficiencies resulting in a good return on investment
  • Improve customer reliability
  • Enable easy access to valuable power system information, especially for planning and maintenance management

SchlumbergerSema has adopted Tasnet's substation automation solution to further broaden the digital enablement of transmission networks by providing a foundation layer for delivering critical information to the utility knowledge infrastructure and bringing essential real-time information into the energy community. Utilizing the Tasnet system’s open architecture, utilities can quickly access vast amounts of real-time information crucial to network operation, allowing them to better resolve issues of capacity management and commodity access.
