Major Accountabilities
1) Perform site evaluations using one-line diagrams to validate field conditions. Interpret Engineering drawings, Construction Standards Manual, survey notes, Accident Prevention Manual, and other drawings
2) Work in coordination with operations for outage scheduling in Transmission Outage Application (TOA) system and switching order development.
3) Develop new and/or redline existing control drawings for field engineered plant, substation and/or supervisory or automated transmission and distribution line equipment construction projects. Assist project coordinator by yellow lining and modifying (if necessary) primarily complex projects. Must have ability to field engineer, modify diagram prints/schematics per design standards as it relates to actual field conditions. Respond to emergent call outs, troubleshoot protection and control systems, and restore system(s) back to a normal state for distribution, EHV and fossil generation systems. Provide protection, metering, and control technical services that are integrated with planning and operational needs, reliably and cost effectively: troubleshoot protection, metering, and control system failures and problems.
4) Conduct shakedown, modify, calibrate and functional test new and existing power plant, substation and/or supervisory or automated transmission and distribution line equipment electrical equipment.
5) Lead evaluation and integration projects of new technology in order to reduce capital and O&M costs and improve overall system reliability.
6) Install and integrate new electrical equipment into new or existing energized substation of transmission and distribution lines for primarily complex jobs.
7) Assume a leadership role in the continuous development and application of company and industry standards wherever appropriate and maintain thorough documentation of all system designs and field changes. Demonstrate leadership with the ability to Project Manage resources and scope of work independently and document work performed and communicate progress updates, including administrative tasks.
8) Responsible to perform as site superintendent or inspector for multiple construction workgroups, maintenance of substation equipment and fossil power plant equipment. Independently plan and conduct work to meet required deadlines. Strong organizational skills with ability to optimize resources reducing costs and outage schedules.
9) Responsible for the planning, scheduling and testing of activities on-time without service interruptions. Inspection and Commissioning activities of all substation and fossil power plant equipment used in the delivery and control of power from AC/DC control voltage to EHV.
10) Perform electromechanical and microprocessor functional testing per regulatory requirements. Provide all testing and commissioning necessary to safely and effectively energize and release equipment to operations for remote control.
11) Functional test new and modified control schemes in preparation for energizing new or simple and complex retrofitted electrical equipment. Assure operations personnel that new substation and supervisory or automated transmission and distribution line electrical equipment can be safely energized and placed in normal operation.
12) Participate on project teams to assist in the development of project scope, schedules, and cost estimates for construction.
13) Effectively communicate with our internal customers to assess their needs and facilitate their understanding of any technical opportunities or limitations that may exist.
14) Assure operations personnel that new power plant, substation and/or supervisory or automated transmission and distribution line electricity.
