DOE Federal Energy Management Program - FEMP

This training program is designed to educate agencies on geothermal heat pumps (GHP) and equip them with the skills to model and evaluate these systems for their specific site(s) using the National Renewable Energy Laboratory's (NREL) REopt tool. The REopt tool, available for free, offers a user-friendly web interface and open-source code, enabling users to assess the techno-economic feasibility of distributed energy resources, including solar photovoltaics, wind turbines, battery storage, geothermal heat pumps, combined heat and power, and thermal energy storage. Participants in this training will gain insights into GHP technology, receive an introduction to the comprehensive REopt tool, delve into the specifics of REopt's GHP model, and learn how to effectively utilize it for site-specific evaluations.


Dan Olis, Research Engineer, National Renewable Energy Laboratory  

Dan Olis is a research engineer at the National Renewable Energy Laboratory. He is a mechanical engineer with experience in mechanical and systems design, plant operations, testing and commissioning, and project management. Currently Dan's focus is techno-economic analyses of distributed energy resources, renewable energy systems integration, and project development. Dan has supported work for private industry, utilities, remote communities, the U.S. Department of Energy, Department of Defense, Department of the Interior, and the Federal Energy Management Agency in the U.S., Caribbean, and Pacific regions. In addition, he is a key contributor to NREL's REopt software tool, a techno-economic decision support platform used by researchers, developers, utilities, and energy managers for identifying distributed energy resources to meet their energy savings, emissions, and resilience goals.

An Pham, Research Engineer, National Renewable Energy Lab  

An Pham is a research engineer in the Modeling and Analysis group in the Accelerated Deployment and Decision Support Center and the Capacity Expansion and Electricity Markets Group in the Grid Planning and Analysis Center. Her work uses macro- and micro-scale energy systems models to inform planning for energy systems transition. Prior to joining NREL, Pham was a postdoctoral research fellow at University of Michigan, where her research focused on grid-scale deployment of negative emissions technologies and techno-economic analysis of emerging distributed energy resource technologies, including thermal energy storage in residential households and small modular reactors in the transportation sector.
