The Energy Systems Integration Facility (ESIF) at the U.S. Department of Energy’s National Renewable Energy Laboratory (NREL) houses an unparalleled collection of state-of-the-art capabilities to study clean energy technologies at all scales—from developing and validating individual appliances or components to running megawatt-sized grid simulations.


The ESIF is the nation’s first research facility that can conduct megawatt-scale research, development, and demonstration (RD&D) of the components and systems needed to seamlessly integrate advanced energy technologies into an evolving grid infrastructure. Through a combination of RD&D tools and approaches, the ESIF helps researchers, entrepreneurs, utilities, and other stakeholders identify and resolve the technical, operational, and financial risks of large-scale integration of renewable energy and energy efficiency technologies.


The ESIF is also home to Eagle—the largest high performance computer (HPC) in the world exclusively dedicated to advancing renewable energy and energy efficiency technologies. Eagle delivers 8 petaflops of computational power that can be used for EERE-funded programs or mission-related work, or for collaborative projects with a growing user community. Designated as an official U.S. Department of Energy (DOE) user facility, ESIF’s scientific capabilities—researchers, instruments and facilities—are available for use by the global research community. Through its user access program, the ESIF allows researchers access to its premier laboratories in support of research and development that aims to optimize our entire energy system at full power.


Requests for access to the ESIF are accepted on an ongoing basis, depending on availability. Various types of solicitations for proposals are also posted throughout the year.
