Grid Facilities

NREL's state-of-the-art research facilities provide the venue for groundbreaking innovations and collaboration in grid research.

Energy Systems Integration Facility

The Energy Systems Integration Facility is the nation's premier user facility for research, development, and demonstration of the components and strategies needed to optimize our entire energy system.

National Wind Technology Center

Located in Boulder, Colorado, the National Wind Technology Center (NWTC) offers similar integration capabilities to the Energy Systems Integration Facility but at a larger 1- to 10-MW scale that goes beyond the physical limitations of the ESIF. Hardware here can be connected virtually to the Energy System Integration Facility's software modeling and power hardware-in-the-loop capabilities—allowing NREL researchers and collaborators to simulate operation of the national electric grid while introducing the effects of renewable energy sources such as wind and solar.

Distributed Energy Resources Test Facility

Our Distributed Energy Resources Test Facility offers state-of-the-art laboratories and outdoor test beds used to characterize the performance and reliability of distributed power systems, support standards development, and investigate emerging and complex system integration issues.
