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.

The training will dive into site data requirements for REopt analyses, with a specific focus on load profiles and utility rate tariffs—two major drivers of DER project economics.

This is the second training of three in the REopt and Federal On-Site Clean Energy Training Series. The final training, Meeting Decarbonization and Resilience Goals, will be held on March 21, 2023.

Learning Objectives

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

  • Describe why load profiles and utility rates are important drivers of DER project economics
  • Clean up metered interval data for use in REopt
  • Simulate interval data using monthly or annual energy consumption data and DOE Commercial Reference Building profiles
  • Describe common types of electric utility rate components
  • Interpret utility bills and model them in REopt.


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.
