NLR is located at the foothills of the Rocky Mountains in Golden, Colorado is the nation's primary laboratory for energy systems research and development. Join the National Laboratory of the Rockies (NLR), where world‑class scientists, engineers, and experts are accelerating energy innovation through breakthrough research and systems integration. From our mission to our collaborative culture, NLR stands out in the research community for its commitment to an affordable and secure energy future.

Spanning foundational science to applied systems engineering and analysis, we focus on solving complex challenges to deliver advanced, secure, reliable, and cost‑effective energy solutions. Our work helps strengthen U.S. industries, support job creation, and promote national economic growth.

At NLR, you'll find a mission-driven environment supported by state‑of‑the‑art facilities, multidisciplinary research teams, and strong collaborations with industry, academia, and other national laboratories. We offer robust professional development opportunities, and a competitive benefits package designed to support your career and well‑being.

This employee will collect the required data and develop fundamental methods and software tools and interfaces required to support large scale electric system capacity expansion. The developed data sets, data specifications, and tools will help inform future planning, policy and infrastructure development.

• Develop the generalized frameworks to link capacity expansion models (CEM), such as GenX and ReEDS, and production cost models (PCM), such as Sienna ps, including automated methods to translate data inputs and results from one form of model to another (leveraging the Sienna ata package).
• Develop automated workflows to estimate maximum power flow transfer constraints between any arbitrary set of aggregated spatial regions (or “zones”) based on a nodal/line‑by‑line model of the continental US transmission system composed from utility-sourced data with power flow simulation capabilities in Sienna ps.
• Work towards automating transmission network designs to enable generation interconnections and transmission capacity augmentations consistent with results from CEMs and develop methods for automated downscaling of zonal CEM results to a nodal PCM for further reliability analysis (and eventually stability analysis) and confirm costs used for transmission expansion used in the CEM.
