Basic Function

The Electrical Engineer - Data Center Power Generation will serve as SB Energy’s owner-side electrical engineering subject matter expert for simple-cycle and combined-cycle gas power generation projects. This role will provide technical oversight throughout engineering, procurement, construction, commissioning, and turnover, helping ensure electrical systems meet project requirements and support safe, reliable plant operation.

The engineer will coordinate electrical design interfaces among original equipment manufacturers (OEMs), engineering, procurement, and construction (EPC) contractors, consultants, and SB Energy’s internal teams. Key responsibilities include reviewing design packages, resolving technical questions, and developing coordinated owner responses to requests for information (RFIs), submittals, and proposed design changes.

Responsibilities

Electrical Engineering and Design Oversight

• Serve as the owner’s electrical engineering SME for simple-cycle and combined-cycle gas generation projects, providing technical guidance from initial design through commissioning and closeout.
• Review electrical design criteria, specifications, calculations, drawings, and equipment selections for alignment with contractual requirements, applicable codes and standards, and plant operating needs.
• Review plant electrical systems, including generator connections, generator step-up and auxiliary transformers, medium- and low-voltage distribution, switchgear, motor control centers, emergency power, DC and UPS systems, grounding, lightning protection, and cable systems.
• Review electrical studies, including load flow, short circuit, protective device coordination, arc flash, motor starting, and grounding; coordinate specialized analyses with qualified internal and external resources.
• Evaluate designs for constructability, maintainability, equipment access, system reliability, and integration with plant operations.
• Identify technical gaps, conflicting requirements, and design risks; track resolution and escalate issues affecting safety, performance, cost, or schedule.

OEM and EPC Interface Coordination

• Coordinate electrical interfaces among gas turbine, steam turbine, generator, and balance-of-plant OEMs and the EPC contractor, as applicable to each project configuration.
• Establish and maintain clear interface requirements, scope boundaries, responsibilities, and required engineering deliverables.
• Coordinate OEM electrical data, equipment ratings, auxiliary load requirements, protection requirements, connection details, and control interfaces for incorporation into the EPC design.
• Verify alignment among OEM package designs, plant distribution systems, protection and controls, plant control systems, and grid interconnection requirements.
• Coordinate with the data center electrical design team, generation OEMs, and EPC contractor to align generation capabilities with campus load requirements, including load ramping, operating modes, protection, controls, and energization sequencing.
• Lead technical interface meetings, document decisions and action items, and drive timely resolution of open issues.
• Work with project management and project engineering personnel to align technical deliverables and decisions with procurement, construction, and commissioning milestones.

Design Reviews RFIs and Submittals

• Lead or participate in electrical design reviews at key project milestones, consolidating owner comments and tracking their disposition through closure.
• Develop and coordinate SB Energy’s technical responses to electrical RFIs, equipment submittals, shop drawings, technical deviations, and proposed substitutions.
• Engage other engineering disciplines, operations personnel, consultants, and OEM specialists when responses affect systems beyond the electrical scope.
• Review proposed design changes for impacts on equipment ratings, protection, reliability, operability, cost, and schedule; provide recommendations to project leadership.
• Maintain clear records of technical decisions, review comments, accepted deviations, and outstanding engineering issues.
• Coordinate reviews with the Owner’s Engineer and support responses to Independent Engineer questions and document requests.

Equipment and Procurement Support

• Develop or review electrical equipment specifications, technical requisitions, and procurement package requirements.
• Perform technical bid evaluations, identify exceptions, and support clarification of supplier proposals.
• Review vendor drawings, calculations, test plans, and technical documentation for compliance with project requirements and coordination with connected systems.
• Support factory acceptance testing and equipment inspections, as required, and coordinate resolution of technical deficiencies.
• Work with procurement and project teams to address technical issues affecting long-lead electrical equipment and delivery schedules.

Utility and Interconnection Coordination

• Coordinate with utilities, ISOs/RTOs, OEMs, and the EPC contractor to address interconnection requirements, resolve technical comments, and align protection, metering, telemetry, and controls interfaces.
• Support interconnection-related energization and commissioning, including outage coordination, required documentation, witness testing, and verification of readiness for grid connection and operation.
• Construction Commissioning and Turnover Support
• Provide owner-side technical support for electrical installation questions, field changes, nonconformances, and construction issues.
