Position Specific Description

The Principal Substation Engineer - Power Plant is responsible for the engineering, design, integration, and technical oversight of high and medium voltage substations directly supporting natural gas fired power plants, including combined cycle (CC), simple cycle, and peaking facilities. This role requires hands on experience coordinating generator step up transformers (GSUs), plant auxiliaries, protection and control systems, and transmission interconnections to ensure safe, reliable, and code compliant operation of dispatchable generation assets.

Key Responsibilities

Substation & Electrical Design

• Engineer and review plant switchyards and substations (typically 13.8 kV, 18 kV, 22 kV, 34.5 kV, 115-500 kV) supporting natural gas generating units.
• Design and review GSU configurations, including bus arrangements, grounding, protection zones, and insulation coordination.
• Develop single line diagrams, three line diagrams, schematics, wiring diagrams, and equipment layouts specific to thermal power plants.
• Specify and apply:
  
  • Power transformers (GSU, UAT, SAT)
  • Circuit breakers, disconnects, CTs, VTs, surge arresters
  • Station service and auxiliary power systems
• Write, conform and adapt Engineer of Record (EOR), Engineering Consultant, Early Stage Engineering, Construction, Engineer/Procure/Construct (EPC) and Owner furnished equipment specifications and other technical contract documents as needed for each project to put contracts in place (self-performed in areas of expertise, seeks appropriate in-house guidance in areas outside of immediate expertise, and where needed uses 3rd party engineering consultants).

• Review or support electrical studies including:
  • Short circuit, load flow, arc flash
  • Insulation coordination and surge arrester selection
  • Grounding and step and touch analysis

Interconnection & Compliance

• Support ISO/RTO and utility interconnection requirements (e.g., NERC, regional transmission owner standards).
• Coordinate with transmission owners, EPCs, OEMs, and commissioning teams.
• Ensure compliance with:
  • EEE, NESC, NEC, NFPA 850, NERC PRC standards
  • Owner and transmission owner design criteria
