Level: Intermediate

REopt® is a techno-economic optimization platform that can be used to evaluate distributed energy resources (DERs) to support energy cost savings, resilience, and decarbonization goals.

This training will dive into REopt's decarbonization and resilience modeling capabilities and how federal agencies can use REopt to evaluate how DERs can support federal decarbonization and resilience goals.

This is the final training of three in the REopt and Federal On-Site Clean Energy Training Series.

Learning Objectives

Upon completion of the course, attendees will be able to:

  • Recognize how REopt can be used to evaluate DERs towards Executive Order 14057 federal decarbonization targets
  • Identify grid emissions rate types, data sources, and applicability (e.g., marginal vs. average emissions rates; EPA's eGRID, EPA's AVERT, and NREL's Cambium datasets)
  • Explain how onsite DERs can support site energy resilience
  • Use REopt to evaluate DERs for resilience and how to interpret and communicate REopt results, especially critical loads, outage survivability, and quantifying the costs and value of resilience to a site.


Kathleen Krah is a research engineer at the National Renewable Energy Laboratory (NREL). Her work centers around NREL's REopt tool, a techno-economic optimization tool for distributed energy systems.

Kathleen leads techno-economic analysis projects to support domestic and international communities, government agencies, and other public- and private-sector organizations seeking to cost-optimally achieve their energy goals—including decarbonization, resilience, and cost-savings priorities.

Additionally, she contributes to REopt tool development, with a focus on expanding emissions and renewable energy modeling capabilities, and now leads the REopt team at the program level.

Kathleen holds an MEngSc in Sustainable Energy Engineering from University College Cork (Ireland) and a BS in Chemical and Biomolecular Engineering from the University of Notre Dame.
