This project by North Carolina's Electric Cooperatives (the power supplier for North Carolina's network of electric cooperatives) and Brunswick EMC (the local distribution cooperative) uses DERs to create a microgrid in a residential neighborhood called Heron's Nest.

On-site generation is provided in Heron's Nest by a community solar array and a Battery Energy Storage System (BESS). OATI's GridMind™ microgrid controller software is used to island the neighborhood from the distribution system during a loss of power to the site. While in "island mode," the microgrid controller provides alarm notification and visualization of the system, exercises load shed, and executes command and control over the BESS and other system components to carry the system load for as long as possible.

When not controlling for resiliency, the microgrid controller controls BESS charge and discharge during peak periods, allowing the microgrid to act as a callable DR asset from the cooperatives' centralized DERMS system.
