Senior Engineer, Transmission System Planning (Hybrid)

Essential Functions

Perform large-scale integration studies (DER, Data Centers, and more) across CT, MA, and NH.

Conduct and manage comprehensive power system impact studies (Feasibility, System Impact Studies) for utility-scale DER projects (Solar PV, Wind, BESS) and large Data Center interconnections (ranging from tens to hundreds of MWs).

Responsible to perform detailed analysis using industry-standard tools (e.g., PSS®E, PSCAD, TARA, Synergi) including :

Validate the inverter models to ensure they meet relevant industry standards

Steady-State Analysis (Power Flow, Short Circuit, Voltage Stability, Thermal Loading)

Dynamic Analysis (Transient Stability, Voltage Ride-Through, Frequency Response)

Electromagnetic Transient (EMT) Studies for inverter-based resources (IBR) and complex interactions.

DER & IBR Focus : Model and analyze the behavior and grid impact of inverter-based resources (solar, wind, BESS), including compliance with modern grid codes (IEEE 1547, ISO-NE PP5-6, IEEE 2800, UL 1741 SB, etc). Participates with other utilities and the planning staff of the Independent System Operator (ISO) in the preparation of regional transmission expansion studies

Identify potential grid issues and develop technically sound and cost-effective mitigation solutions (e.g., upgrades, FACTS devices, control settings).

Serve as the primary technical point of contact for utilities (ISOs, Transmission Owners, Distribution Utilities) throughout the interconnection process.

Prepare clear, concise, and comprehensive technical reports, study results, and presentations for internal stakeholders and external clients / utilities.

Provide technical guidance and mentorship to junior engineers. Contribute to the development of internal study methodologies, standards, and tools

Maintain deep understanding of relevant interconnection procedures (FERC, NERC, state-specific), technical standards (NERC PRC, TPL, IEEE), and evolving grid requirements.
