As threats from extreme weather, aging infrastructure, and grid disruptions increase, local leaders are searching for ways to keep critical services running for communities when the power goes out.
One of the most promising solutions is the microgrid.
A microgrid is a localized energy system that can operate independently from the utility grid when outages occur. By providing reliable backup power to essential facilities, microgrids are helping communities strengthen resilience and maintain critical services when they are needed most.
What is a Microgrid?
A microgrid is a self-contained energy system that combines energy resources such as solar panels, wind turbines, battery energy storage systems, and backup generators with advanced control technology.
Under normal conditions, a microgrid operates alongside the utility grid. During a power outage, however, it can disconnect and continue supplying electricity to designated facilities and services. This capability, known as “islanding,” allows critical operations to remain powered even when the surrounding area loses service.
Because of this flexibility, microgrids are increasingly being deployed at:
- Community centers
- Schools
- Healthcare facilities
- Emergency shelters
- Public safety buildings
- Critical infrastructure sites
Why Community Resilience Matters
Community resilience is about more than simply keeping the lights on.
During prolonged power outages, residents can lose access to:
- Heating and cooling
- Communications systems
- Refrigeration for food and medicine
- Medical equipment
- Device charging
- Emergency services
These disruptions often affect vulnerable populations first and most severely.
Microgrids help communities prepare for these situations by supporting resilience hubs—facilities that remain operational during emergencies and provide essential services to residents.
These hubs can serve as locations for:
- Charging phones and devices
- Preserving medications
- Distributing food and supplies
- Accessing information and communications
- Providing shelter and community support
In addition to improving emergency preparedness, microgrids can reduce energy costs, support renewable energy adoption, and increase local energy independence throughout the year.
Resilience Hubs Powered by Microgrids
Across the United States, communities are transforming trusted public spaces into resilience hubs powered by microgrids.
Schools, libraries, senior centers, nonprofit organizations, and community centers are investing in solar energy, battery storage, and advanced control systems that allow them to remain operational during grid disruptions.
These projects demonstrate that resilient energy infrastructure is not only an engineering solution—it’s a community investment that improves public safety, strengthens local services, and supports long-term sustainability goals.
Spotlight: ELM MicroGrid and the MLK Resilience Community Center
A compelling example of community resilience in action can be found at the Dr. Martin Luther King Jr. Family Outreach Center in Spokane, Washington.
The MLK Center provides numerous services to local families, including:
- Food assistance
- Childcare programs
- Educational resources
- Senior support services
Avista and ELM MicroGrid to create one of Eastern Washington’s first community-based resilience hubs powered by a microgrid.
The system combines:
- Rooftop solar generation
- Battery energy storage
- Backup generation
- Advanced microgrid controls
Together, these technologies allow the facility to continue operating during extended power outages.
When the grid goes down, the center can remain open and serve residents as a safe gathering place while supporting critical community services.
For ELM MicroGrid, the project reflects a commitment to developing resilient, community-focused energy solutions that prioritize reliability, continuity of service, and local impact.
The MLK Center demonstrates how advanced energy technologies and strong community partnerships can work together to create meaningful, long-term resilience.

Building a More Resilient Future
As climate risks and grid reliability challenges continue to grow, microgrids offer communities a practical path toward greater resilience.
By supporting critical infrastructure, powering resilience hubs, and maintaining essential services during emergencies, microgrids help communities prepare for the unexpected while advancing long-term sustainability goals.
Projects like the MLK Center show that microgrids do far more than provide electricity. They help communities stay connected, supported, and operational when it matters most.
Through collaboration among utilities, community organizations, public agencies, and technology providers such as ELM MicroGrid, resilient local energy systems are becoming an increasingly important part of the future energy landscape.
