Principal Project Engineer - Substations Power Generation

Your Impact as a Principal Project Engineer

We seek an experienced electrical Project Engineer to lead engineering and design integration for utility-scale and behind-the-meter power projects, with primary responsibility for high- and medium-voltage substations and the electrical balance of plant. The role spans concept development, utility interconnection, detailed design, procurement, construction support, commissioning, and energization.

• Establish the electrical design basis, scope boundaries, interface matrix, deliverable register, design schedule, and technical risk register;
• Identify and close scope gaps across owners, EPC contractors, utilities, consultants, and equipment suppliers;
• Review electrical design packages including: single-line and three-line diagrams, wiring diagrams, cable schedules, equipment layouts, grounding and lightning-protection designs;
• Create or technically evaluate specifications for all major equipment including: transformers, HV/MV switchgear, disconnect switches, power cables, CTs/VTs, metering and protection relays and UPS systems;
• Coverge electrical interfaces with natural-gas engine-generator OEMs, including alternator ratings, neutral grounding, excitation/AVR, governor and synchronizing controls, generator protection, starting systems, plant auxiliaries, black-start or islanding requirements, and CHP interfaces where applicable;
• Review load-flow, short-circuit, protection-coordination, grounding, arc-flash, cable-ampacity; ensure study assumptions remain aligned with the issued-for-construction design;
• Coordinate with utilities for utility interconnection requirements, including point-of-interconnection design, revenue metering, communications and relay settings;
• Review EPC and vendor drawings, calculations, equipment data sheets, test plans, FAT/SAT reports, deviations, and technical submittals; provide clear dispositions and maintain design configuration control;
• Manage procurement through equipment specifications, technical bid evaluations, supplier selection and vendor-document review;
• Support procurement through equipment specifications, technical bid evaluations, supplier selection and vendor-document review;
• Provide construction engineering support, respond to RFIs and field changes, participate in site walkdowns, and verify that installations conform to the design, applicable codes, and approved quality plans;
• Plan and support substation energization, generator synchronization, commissioning, and turnover, including test procedures, protection and control testing, punch-list closure, and coordination with utilities, commissioning agents, and plant operations.
