NREL Energy Systems Integration Facility (ESIF)

The Energy Systems Integration Facility (ESIF) on the campus of the U.S. Department of Energy’s National Renewable Energy Laboratory (NREL) is the nation’s only facility that can conduct integrated megawatt-scale testing of the components and strategies needed in order to safely move clean energy technologies onto the electrical grid “in-flight” at the speed and scale required to meet federal policy.  

The ESIF includes a high-performance computing and data center (HPCDC) that serves the breadth of NREL, expanding the laboratory’s capabilities in modeling and simulation of renewable energy technologies and their integration into the existing energy infrastructure. The petaflop-scale (one petaflop equals one quadrillion floating-point operations per second) high-performance computer enables large-scale modeling and simulation of material properties, processes and fully integrated systems that is too expensive, too dangerous, or even impossible, to study by direct experimentation. 

Not only is the HPCDC the fastest computing system dedicated to renewable energy efficient and renewable energy technologies in the world, it is one of the most energy efficient data centers in the world operating at a power usage effectiveness (PUE) rating of 1.05 annual average.
