Distributed Energy Testing and Certification

This microturbine is one of many generation technologies tested at NREL's Distributed Energy Resources Test Facility.

For distributed energy resources to become common in our electric power system, they must first be tested, characterized, and certified. Thorough testing and certification will ensure these systems perform safely and reliably.

NREL's distributed energy resource testing and certification activities are performed primarily at the Distributed Energy Resources Test Facility. This state-of-the-art facility includes generation, storage, and interconnection technologies as well as electric power system equipment to simulate a real-world electric system.

Researchers at the facility can vary equipment configurations and introduce common electrical disturbances such as sags, swells, and harmonic issues. These capabilities allow them to evaluate the real-time dynamics of distributed power systems, collect information about the long-term performance of such systems, and test new design concepts.
