  • Working knowledge of modeling renewable generation in PowerWorld, PSSE, and/or PSLF, with ability to learn and apply company standards.
  • PSCAD modeling experience is a plus.
  • Familiarity with interconnection study models and interconnection request packages (or demonstrated ability to learn quickly).
  • Understanding of model verification/validation concepts (e.g., ride-through and stability tests) and willingness to develop hands-on experience.
  • Familiarity with steady-state, dynamics, and short-circuit data requirements and reporting procedures, including required model inputs.
  • Works effectively across internal teams and external partners (consultants, EPCs, and utilities), tracking action items and communicating status under the guidance of senior team members.
  • Completes assigned work with supervision; takes initiative, communicates progress, and escalates questions and risks appropriately.

  • Identify opportunities to improve modeling workflows and documentation; propose changes for review and implementation by the team.
  • Prepare draft generator models and supporting documentation for interconnection request packages, as-built submittals, and ISO/NERC requirements under supervision and review.
  • Support consultant-delivered plant models (PSLF, PSSE, PSCAD, Aspen) by reviewing inputs/assumptions, tracking comments, and coordinating updates with the project team.
  • Assist with ensuring generator model builds align with Transmission Planner and Planning Coordinator expectations (e.g., ride-through and reactive power requirements) and help confirm parameters are reasonable.
  • Gather and document model input data from manufacturers, contractors, and consultants, including sources and assumptions, for review.
  • Verify generator models with substation schematics, inverter/turbine settings, power plant controller behavior, and generator properties.
  • Support tracking and implementation of generator model requirements per ISO, NERC, and IEEE, escalating impacts and questions to senior engineers.
  • Support model validation field tests for MOD-025, MOD-026, and MOD-027 verifications, including planning support, data review, and documentation.
  • Support project compliance activities related to PRC-019, PRC-029, and IEEE2800/IEEE2800.2 under the direction of senior engineers.

Desired Education, Skills and Experience:

  • Bachelor’s degree in engineering
  • 0-3 years of experience with modeling software (power system modeling preferred); relevant internships/co-ops count.
  • Strong organizational skills and ability to prioritize projects and tasks.
  • Understanding of modeling simulation requirements (NERC MOD, PRC, IEEE).
  • Excellent understanding of inverter-based technology operations and inverter settings.
  • Proficient in reading substation schematics and understanding inverter/turbine/control settings.
  • Strong communication skills and ability to contribute to technical discussions with EPCs, ISOs/Utilities, consultants, and internal stakeholders.
