Building Resiliency into Grand Canyon West Micro-Grid

Summary

The Hualapai Indian Tribe faced challenges with an unreliable and costly diesel-powered micro-grid at Grand Canyon West. Their approach was to build resilience by integrating an 885-kW solar PV array and a 750-kW/2,145-kWh battery energy storage system (BESS) to provide 50% of annual energy needs. The project has been completed and is operational, with monitoring data indicating occasional curtailment due to fully charged batteries and low demand.
