Responsibilities

• Develop and assess power-system architectures for utility supply, substations, energy storage, load management, on-site generation, and campus electrical interfaces.
• Produce technical requirements, design criteria, calculations, specifications, and engineering recommendations for site-specific and repeatable fleet solutions.
• Apply established engineering standards and contribute to the development of global design philosophies, modeling methods, technical acceptance criteria, and validation practices.
• Identify technical risks, constraints, and opportunities affecting capacity, schedule, resiliency, operability, and future campus expansion.
• Translate complex grid and power-system issues into clear technical recommendations for project and business stakeholders.
• Perform technical evaluations of utility capacity, transmission and distribution infrastructure, substations, reliability, power quality, fault duty, and expansion requirements.
• Support engagement with utilities, transmission providers, ISOs/RTOs, developers, and engineering partners on interconnection and power-delivery solutions.
• Define and review requirements for interconnection facilities, substations, protection and controls, grounding, and campus electrical interfaces.
• Evaluate alternatives that may accelerate energization, reduce delivery risk, or unlock additional capacity.
• Provide technical analyses and engineering support to Energy Contracting during utility negotiations and commercial discussions.
• Conduct power-system due diligence for prospective data-center sites.
• Develop conceptual power architectures and compare utility and behind-the-meter alternatives during site selection and early development.
• Assess interconnection complexity, infrastructure lead times, system reliability, power quality, and long-term expansion potential.
• Partner with Real Estate, Site Development, Capacity Planning, and Energy Contracting to incorporate power feasibility into site and investment decisions.
• Develop engineering analyses and technical requirements for battery energy storage systems, including sizing, controls, protection, operating modes, safety, degradation, and lifecycle performance.
• Evaluate BESS use cases including resiliency, grid support, load management, transient response, and capacity optimization.
• Analyze load-curtailment, demand-response, flexible-load, ramp-rate-management, and peak-reduction opportunities with utilities.
• Develop and assess architectures coordinating utility supply, data-center load, BESS, UPS systems, and on-site generation.
• Support engineering of natural-gas generation, fuel cells, microgrids, renewable generation, and emerging power technologies.
• Evaluate generation configuration, synchronization, protection, controls, grounding, black-start capability, islanding, fuel supply, emissions constraints, and maintainability.
• Perform or coordinate load-flow, short-circuit, protection coordination, harmonic, transient, dynamic stability, grounding, and arc-flash studies.
• Use PSCAD, ETAP, SKM, EMTP, or comparable tools to model interactions among utility systems, generation, BESS, UPS technologies, and dynamic data-center loads.
• Develop models and analysis methods that account for evolving AI and high-performance-computing load characteristics.
• Support First-of-a-Kind qualification plans, including factory, laboratory, and site testing for power-system technologies.
• Define test scenarios and acceptance criteria covering normal operations, transitions, failure modes, recovery, dynamic response, and system interactions.
• Document results and recommend whether technologies are ready for broader fleet deployment.
• Evaluate emerging technologies that may improve power availability, resiliency, utilization, cost, or deployment speed.
• Work with OEMs, utilities, laboratories, consultants, and engineering partners to resolve technical issues and improve proposed solutions.
• Contribute technical input to technology qualification roadmaps and standardization efforts.
• Support the transition of successful site-specific or FOAK solutions into repeatable engineering practices.
