Senior Engineer, Transmission System Planning

Senior Engineer Position

We seek a highly experienced Senior Engineer to conduct system studies of electric transmission system planning related to clean energy and large load integration. Familiar with technical studies such as load flows, stability studies, and transient network, short circuit analysis, and Electromagnetic Transient Analysis (EMT) to support clean energy and large load interconnections. Authorization to work in the United States is a precondition to employment in this position. Eversource will not sponsor candidates for work visas for this position. We seek a highly experienced Senior Engineer to lead technical studies for the interconnection of large-scale Distributed Energy Resources (DER) and Data Centers to the transmission and distribution grid. You will be instrumental in ensuring the reliable, safe, and efficient integration of these critical assets, solving complex power system challenges and supporting our clients' decarbonization and digital infrastructure goals. This is a hybrid position. The first 3 months are in the office.

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., PSSE, 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
