High-Performance Computing and Data Visualization

NREL's High-Performance Computing (HPC) Data Center, supercomputing systems, and visualization capabilities propel technology innovation by tackling energy challenges that cannot be addressed through traditional experimentation alone.

NREL's supercomputer, Kestrel, which resides in the Energy Systems Integration Facility.

NREL's HPC experts collaborate with scientists and engineers to take full advantage of advanced computing hardware and software resources that provide the computing scale and speed necessary to advance renewable energy and energy-efficiency technologies. Advanced visualization technology helps researchers explore and interact with data in new ways that accelerate understanding and innovation. Computational science is a key driver of energy systems integration research in the ESIF.

NREL is installing our third-generation HPC system, Kestrel. Kestrel’s approximately 44 petaflops of computing power will accelerate energy efficiency and renewable energy research at a pace and scale more than five times greater than Eagle. See how Kestrel stacks up against the previous system, Eagle, and follow our Countdown to Kestrel Blog for installation updates.
