Hardware-in-the-Loop at Megawatt-Scale Power: Megawatt-scale power-in-the-loop allows researchers and manufacturers to conduct integration tests at full power and actual load levels in real-time simulations and evaluate component and system performance before going to market.
High Performance Computing Data Center: Petascale computing at the High Performance Computing Data Center enables unprecedented large-scale modeling and simulation of material properties, processes, and fully integrated systems that would otherwise be too expensive, too dangerous, or even impossible to study by direct experimentation.
Uniquely Connected: Each lab in the ESIF has its own niche with different kinds of equipment and functionality fostering research on all aspects of energy integration. The Research Electrical Distribution Bus, the ultimate power integration circuit, is made up of two AC and two DC ring buses that connect multiple sources of energy and interconnect "plug-and-play" testing components in all the labs.
Supervisory Control and Data Acquisition System: Integrated throughout the ESIF, a SCADA system monitors and controls the Research Electrical Distribution Bus operations and safety and gathers real-time, high-resolution data for collaboration and visualization.
Data Analysis and Visualization: Analysis and visualization capabilities at the ESIF go beyond what is found in a typical utility operations center. Fully integrated with hardware-in-the-loop at power capabilities, an electrical distribution bus, a SCADA system, and petascale computing, the ESIF allows researchers and NREL partners to visualize complex systems and operations in a completely virtual environment.
NREL sponsored ESIF workshops to solicit insight from energy stakeholders and potential partners on the design and functionality of the facility, to identify priority R&D needs related to transforming our nation's energy system, and to raise awareness of the ESIF's innovative capabilities and partnering opportunities.
