 * Apply and interpret NERC, FERC, ISO/RTO, TSP requirements for both generation and large load interconnections.
 * Develop and validate steady state models in ETAP and PSSE, and dynamic models in PSSE and PSCAD for:
 * Large electronic loads (e.g., data centers)
 * PV, wind, and BESS resources
 * Support development and integration of:
 * Solar/Wind/BESS Power Plant Controllers (PPCs)
 * Master Plant Controllers (MPCs)
 * Participate in EPC HV/MV substation design studies for:
 * Large data center projects
 * Utility-scale PV, wind, and BESS projects
 * Support or lead microgrid design and control studies at MV and HV levels.
 * Support RTDS / RSCAD CHIL testing (Control Hardware-in-the-Loop).
 * Interface with Transmission Service Providers (TSPs), ISO/RTOs (especially ERCOT), developers, OEMs, and project stakeholders.
 * Perform steady-state and short-circuit analyses including: Load flow studies, Short circuit analysis, Protection coordination, Arc-flash studies, Reactive power and energy loss analysis, and Harmonic studies
