• Identify relevant design criteria for high availability power system supplying data centers. • Define and own the overall power system architecture for data centers from utility point of interconnection through IT load. • Design high-reliability substations aligned with Tier III / Tier IV reliability standards for up to 50MW data centers. • Lead failure modes and effects analysis (FMEA), short-circuit studies, coordination studies, and reliability assessments. • Ensure systems are designed for maintainability without downtime, including concurrent maintenance strategies. • Support black-start, islanded operation, and degraded-mode operating scenarios where applicable. • Design on-site or co-located generation, including: diesel or gas turbine generators; Battery energy storage systems (BESS); Co-located or on-site photovoltaic (PV) systems. • Define control strategies for dispatch, load-shedding, islanding, resynchronization, and grid interaction. • Coordinate integration of DERs with UPS systems, static switches, and data hall distribution. • Lead technical engagement with utilities, ISOs/RTOs, and interconnection authorities. • Support interconnection studies, protection coordination with utility systems, and compliance with grid requirements. • Interface with EPCs, OEMs, and equipment suppliers to ensure design intent is preserved through execution. • Establish and maintain design standards, reference architectures, and technical guidelines across multiple sites or regions. • Provide technical oversight during design reviews, FATs, SATs, commissioning, and energization. • Support operational teams with troubleshooting, root-cause analysis, and system upgrades over the asset lifecycle. • Work cross-functionally with engineering, legal, commercial, and executive teams to align project goals.
