    Case Study

    A Community-Driven Island Microgrid

    Powered by a single undersea transmission line and accessible only by ferry or small plane, Orcas Island is uniquely vulnerable to disruption. In the event of an earthquake, wildfire, or severe weather, residents could be cut off from critical supplies and services for days.

    The San Juan County Emergency Management (SJCEM) agency identified the Orcas Center as a facility that could function as a critical emergency support hub if reliable backup power could be installed. At the time, however, the Center had no energy resilience infrastructure. A prolonged outage would leave it dark and inaccessible just when the island needed it most.

    Recognizing this gap, SJCEM began exploring options for a solar- and battery-based microgrid system that could keep essential services online during emergencies while reducing operating costs under normal conditions.

    In other words, this island facility was interested in “islanding” from the grid.
