The Big Picture

As a Senior Grid Studies Expert, you will lead and execute power system studies supporting renewable and conventional generation interconnections across US ISOs/RTOs. This role focuses on performing detailed analytical studies, ensuring regulatory compliance, and translating grid requirements into technically robust and commercially viable interconnection solutions. You will work at the intersection of transmission planning, interconnection engineering, and reliability compliance for grids.

What you can expect as a Senior Grid Studies Expert:

• You’ll turn grid rules and market frameworks into forecasting, dispatch, and bidding logic that can be simulated, validated, and deployed with confidence.
• You’ll design and validate control strategies for DERs, BESS, inverters, and grid-interactive assets
• You’ll perform Feasibility, System Impact, and Facilities Studies aligned with US ISO/RTO processes such as PJM Interconnection, MISO, CAISO, ERCOT, and ISO New England
• You’ll conduct load flow, short circuit, contingency and transient stability studies
• You’ll evaluate renewable (Solar/Wind), BESS, and hybrid plant interconnections
• You’ll assess system strength, voltage stability, and reactive power performance
• You’ll identify required transmission upgrades and develop technical justifications
• You’ll perform protection coordination and breaker duty evaluations
• You’ll support compliance with NERC standards (TPL, MOD, PRC)
• You’ll prepare detailed technical study reports for US utility and ISO submissions
• You’ll coordinate with clients, ISO planners, and internal design teams for model validation and comment resolution
• You’ll review dynamic models (GENROU, REGC_A, REEC_B, etc.) for inverter-based resources
• You’ll support regulatory documentation and audit requirements

Essential Qualifications include:

• 6-12 years of experience in Grid Analytics, Power Systems, or Transmission Planning
• Strong foundation in: Power systems fundamentals, Transmission planning principles, Control systems (classical / modern control concepts), Grid dynamics with high renewable and DER penetration, Fault analysis and protection philosophy, Stability analysis of inverter-based resources
• Experience performing interconnection studies for US utilities
• Proficiency in at least one of the following: PSS®E / PSLF / PSCAD / ASPEN / ETAP
• Strong technical documentation and reporting skills aligned with US standards

Great to have:

• Experience in distribution-level hosting capacity or DER impact studies
• Exposure to large-scale renewable portfolios
• Familiarity with FERC-driven interconnection reforms
• Client-facing or consulting experience with US stakeholders
• Exposure to hybrid plants (Solar + BESS) or grid-forming inverters
