RWE is seeking a technically strong, and motivated (Senior) Grid Modeling Manager to support the development, validation, and maintenance of electrical models across RWE’s multi‑GW renewable energy portfolio. In this highly visible role, you will support application‑stage model development, validation, documentation, and technical inputs for utility‑scale wind, solar, BESS, and gas projects. The role will focus on internal preparation of modeling packages and high‑level design inputs, while coordinating with consultants for specialized PSCAD, TSAT, EMT, benchmarking, and model tuning work.

• Lead and support preparation of ISO/RTO interconnection modeling packages, including application data, PSS®E inputs, DYR files, single‑line diagrams, equipment assumptions, and related technical documentation.
• Have a general understanding of PSCAD, TSAT, and PSS®E benchmarking terminology and workflows, with the ability to coordinate consultant‑led studies, understand key deliverables, and support review of results without requiring hands‑on model tuning experience.
• Develop, maintain, validate, and document electrical models for utility‑scale wind, solar, BESS, and gas projects, with a focus on PSS®E models and interconnection application requirements.
• Prepare and review basic plant representation, inverter selection and sizing assumptions, impedance calculations, transformer assumptions, collector system assumptions, and steady‑state inverter modeling inputs.
• Support short‑circuit and ASPEN One‑liner model development or review where applicable.
• Review consultant outputs for reasonableness, completeness, and alignment with project assumptions, ISO/RTO requirements, and RWE’s development strategy.
• Resolve ISO/RTO modeling deficiencies and support updates related to queue applications, material modification requests, design changes, and project reconfigurations.
• Understand, track, and interpret evolving grid code and modeling requirements, including NERC, ISO/RTO, IEEE , and P2800.2 requirements related to inverter‑based resources.
• Develop and improve internal modeling standards, quality‑control practices, documentation templates, and repeatable study workflows.
• Cross‑train and mentor junior engineers and transmission team members on modeling practices, application package preparation, power system fundamentals, and ISO/RTO modeling expectations.

• Bachelor’s degree in Electrical Engineering, Power Systems, or a related field;
  Master’s degree preferred.
• Minimum of five (5) years of relevant experience in power systems modeling, model development, interconnection support, or grid compliance for utility‑scale generation projects.
• Proficiency with PSS®E, ASPEN One‑liner, and related interconnection modeling inputs.
• Experience preparing or supporting interconnection queue application packages, including model files, single‑line diagrams, application data, equipment assumptions, and deficiency responses.
• Strong understanding of ISO/RTO modeling and interconnection requirements in MISO, PJM, SPP, NYISO, and SERC regions.
• Experience preparing interconnection queue packages and resolving ISO/RTO modeling deficiencies.
• Experience with utility‑scale solar, wind, BESS, and gas projects, including I  behavior, PSS/E DYR files, UDM/generic models, model validation, and dynamic, short‑circuit, reactive power, EMT, and material modification studies.
• Experience with single‑line diagrams, impedance calculations, equipment assumptions, transformer assumptions, high‑level design support, application data preparation, and steady‑state inverter modeling.
• Ability to manage multiple priorities in a fast‑paced and challenging environment.
• Strong written and verbal communication skills, including the ability to explain technical modeling issues to project development, engineering, transmission, and management teams.

• Professional Engineer (PE) license in one or more states.
• In‑depth hands‑on experience with PSCAD, TSAT, and PSS®E benchmarking, model…
