Substation Engineer

Description

Coordination and Review

The Substation Engineer will prepare technical documentation, electrical studies, and construction deliverables and collaborate with multidisciplinary teams to successfully deliver complete, buildable designs.

The Substation Engineer is responsible for the engineering design and analysis of substations and high-voltage lines (Gen-Tie) for utility-scale PV projects. This includes the development of substations, overhead and underground transmission (Gen-Tie) lines, protection and control systems, and interconnection facilities. The role requires ensuring compliance with applicable codes, standards, and grid regulations, while optimizing designs for safety, reliability, and cost efficiency.

• Participate in meetings with the Owner’s Engineer and other project stakeholders to ensure technical alignment.
• Review Owner’s Requirements, contractual specifications, and ensure design compliance with applicable standards (IEEE, IEC, ANSI, NFPA, NEC, NESC, etc.).
• Prepare interlocking logic, communication architectures, and detailed schematics for protection and control systems.
• Conduct route selection, feasibility, and techno-economic studies for HV transmission lines.
• Prepare technical reports and perform electrical and mechanical calculations for overhead and underground lines, including conductor sizing and auxiliary systems (AC/DC).
• Conduct technical assessments and validations of HV equipment, materials, and system supplies (e.g., transformers, breakers, switchgear, towers).
• Review and provide technical feedback on engineering documentation prepared by subcontractors or external consultants.
• Perform basic and detailed design of HV substations and transmission lines, including electrical studies, calculations, and system analysis.
• Coordinate with civil and structural teams on substation and transmission line design requirements.
• Prepare detailed technical specifications, Bill of Quantities (BoQ), and design deliverables for procurement and construction.
• Conduct short-circuit studies, grounding grid calculations, insulation coordination, lightning protection analysis, and instrument transformer loading assessments.
• Ensure interconnection and grid code compliance (reactive power, short-circuit levels, and power quality).
• Hold meetings with suppliers for technical evaluation, clarification, and equipment selection.
• Manage interfaces between HV and PV plant designs across electrical, civil, structural, and instrumentation disciplines.
• Develop and review protection coordination studies and relay settings.
• Develop single-line diagrams (SLDs), protection and control SLDs, wiring and communication diagrams, and signal lists.

Requirements

• Ability to work collaboratively across multiple departments and with external partners.
• Advanced proficiency with Microsoft Excel, AutoCAD, Bluebeam, CYMCAP, CDEGS, PLSCADD.
• 2+ years of experience in HV engineering, preferably within the renewable energy, transmission, or utility industries.
• Familiarity with NEC, NESC, IEEE, and IEC codes and standards.
• Proven experience in substation and transmission line design.
• Bachelor’s degree in Electrical Engineering, Power Systems focus preferred.
• Direct experience with EPC or self-perform construction in solar PV and/or BESS projects, preferably within U.S.-based EPCs or Prime Contractors.
• Strong analytical, organizational, and communication skills, with a high level of attention to detail.

Benefits

• Competitive compensation and comprehensive benefits.
• Opportunity to shape the construction strategy and culture of a rapidly growing renewable energy company.
• Entrepreneurial environment with direct impact on company success and growth trajectory.
