Technical Specialist

The Technical Specialist I-III Transmission and Distribution (T&D) Services (DATA) is a member of a team responsible for the development and maintenance of the digital connectivity model for Oncor’s 69kV, 138kV and 345kV bulk power grid, within the Energy Management System (EMS). This model represents approximate one-third of the state’s bulk power grid, data for over 2000 stations, 10 million meters and is used 24x7 by Transmission Grid Operations to safely and reliable deliver electricity to Texans. The incumbent will also work with highly trained individuals to build and enhance the application’s configuration and displays to improve the real time operational experience of the Grid Operators.

Key Roles & Responsibilities

Other duties may be assigned. Directly or through others, the incumbent:

• Performs all essential functions and aspects of the job including any other duties as assigned.
• Using engineering one-line drawings, assist other Technical Specialists in the work group to create the database and/or display representation of substations, and associated transmission lines, including the definition of electrical connectivity and graphical information.
• Using appropriate EMS editors, assist other Technical Specialists in the work group to develop the SCADA (supervisory control and data acquisition) definitions for the integration of Remote Terminal Units (RTUs).
• Responsible for updating Transmission Management System (TMS) databases, and the associated Common Information Model (CIM) Studio connectivity model, as necessary to represent topology changes based on engineering one-line diagrams and RTU point assignment sheets.
• Responsible for designing and sequencing display updates to support RTU checkout, asset commissioning and equipment energization using available documentation such as engineering one-line diagrams and construction sequence drawings.
• Responsible for supporting database synchronization and validation between the EMS Program and Development System (PDS), Quality Assurance System (QAS), and Production system (PROD).
• Respond to problem reports from the Grid Operators and the EMS user community.
• Assist in testing code updates to the EMS prior to implementation on the production system.
• Assist in monitoring the status and troubleshooting of the EMS database/display applications.
• Review and implement design configuration changes to support modifications to the EMS application.
