Perform and review generation interconnection analysis, deliverability analysis and contingency analysis using study tools such as TARA, PSSE and Power world as needed.
Review interconnection study results, quantify risks and identify opportunities to reduce the network upgrade cost exposure during the interconnection queue studies.
Review transmission plans for various regions and ensure that powerflow models are up to date for internal analysis to support company’s strategic growth.
Conduct screening and identify transmission capacity across areas of interest for high-quality development locations (green field development)
Gather the data and intelligence from Interconnection queues and utility IRPs for developing scenarios.
Use Python to automate modeling, processing frequently used large data sets, inputs and outputs for the various study processes.

Requirements

Ability to prepare high-quality model quality reports, presentations, documentation, and market data to support project development efforts.
Ability to function in a team and demonstrate a strong motivation to succeed in a very fast-paced environment.
Ability to perform detailed technical analysis, synthesize results and automate repeatable processes.
Ability to communicate technical issues effectively to non-technical audiences and higher management.
Technical Skills:
Demonstrated proficiency with TARA, PSSE, Powerworld or similar powerflow tools; PROMOD, PLEXOS, PROBE or similar production cost tools;
Working knowledge of the interconnection procedures in MISO, PJM, SPP, CAISO and/or ERCOT
Proficiency with Python, excel and MS Office Suite

Education/ Experience

Must be authorized to work for any US employer, without the need for work visa sponsorship now or in the future.
Bachelor’s degree or higher in electrical engineering or related quantitative discipline.
Minimum 4 years of experience is required in:
Economic modeling and/or energy market data analysis with PROMOD, PLEXOS, PROBE or UPLAN (or)
Powerflow analysis (NERC TPL assessment and/or reliability analysis), generation interconnection studies, or power system dynamic simulations with TARA, PSSE, Powerworld or PSAT/TSAT.
