Grid Integration Facilities at Flatirons Campus

Located in Arvada, Colorado, NREL's Flatirons Campus offers similar integration capabilities to the Energy Systems Integration Facility but at a larger (up to 20 MW) scale. Hardware here, such as wind turbines, battery energy storage systems, and solar arrays, can be connected virtually to the Energy System Integration Facility's software modeling and power hardware-in-the-loop capabilities.
