Heat waves, hurricanes, wildfires, and ice storms knock out power for days at a time. Community resilience hubs can fill the gap, but only if they have backup power. Solar alone won't help (it shuts off when the grid does, by design). Solar paired with battery storage keeps the lights on, fridges running, and devices charged when neighbors need it most. RE-volv's recoverable grant covers the full system at zero upfront cost.
What is a community resilience hub?
A community resilience hub is a trusted, community-serving facility designated to provide critical services during emergencies and grid outages. Common examples:
- Community centers serving low-income or vulnerable neighborhoods
- Libraries (already public-serving and AC'd)
- Faith centers (often have large gathering spaces and community trust)
- Schools (large, climate-controlled, dispersed across neighborhoods)
- Senior centers (already serving medically dependent residents)
- Health clinics (critical services during emergencies)
Many cities and states have begun formally designating resilience hubs (USDN, Resilient Cities Catalyst, BRIC). If your nonprofit fits this role, formally designated or not, solar + storage turns it into a genuine asset for your community during crisis.
Why solar alone isn't enough
Most rooftop solar systems shut off automatically during grid outages. This is required by "anti-islanding" rules, for safety of utility workers fixing the grid. Without batteries, your solar system is dark exactly when neighbors need power most.
Solar + battery storage solves this. The battery isolates from the grid during an outage, running the building from stored energy and ongoing solar production. Critical loads, lights, outlets, refrigeration, medical equipment, communication, keep running.
What solar + storage typically powers during an outage
Hub systems are typically sized for "critical loads" rather than full building operation:
- Lighting, life safety, navigation, calm
- Outlets, phone/device charging for evacuees
- Refrigeration, food, refrigerated medications
- Medical equipment, oxygen concentrators, dialysis pumps, CPAP machines
- HVAC zones, at least one cooling/warming room
- Internet/communication, coordinating with emergency services and family
A typical hub system provides 24-72 hours of backup for critical loads. Larger systems can run indefinitely if the sun is out.
Stacking with FEMA, BRIC, CDBG-DR, and state resilience grants
Many resilience hub partners stack RE-volv's recoverable grant with disaster preparedness funding from federal and state programs:
- FEMA BRIC (Building Resilient Infrastructure and Communities), federal pre-disaster mitigation
- CDBG-DR, Community Development Block Grant Disaster Recovery
- State resilience funds, many states (CA, NY, MA, NJ, etc.) have hub-specific funding
- USDN, Urban Sustainability Directors Network grants
We provide documentation funders need (project specifications, resilience case study, community-impact metrics).
The application process for resilience hubs
- Apply, note your hub designation status and resilience use case.
- Resilience assessment, we identify critical loads (medically dependent neighbors? cooling room? refrigeration?) and size storage accordingly.
- System design, solar + battery configured to your specific resilience scenarios.
- Stacking review, if you're applying for FEMA BRIC, state resilience funds, or other grants, we coordinate.
- Installation, local installer handles solar + storage. 4-8 months for combined systems.
- Operation, daily savings + ready-to-deploy backup.
Real-world resilience hub scenarios
Imagine these moments, they happen every year somewhere in the U.S.:
- Heat dome: Three days of 105°F+ temperatures + grid outages. Your hub keeps cooling rooms operational for elderly residents without home AC.
- Hurricane aftermath: A week without power. Your hub charges 100+ phones a day, refrigerates donated food, runs medical equipment.
- Ice storm: Day-long outage in winter. Your hub provides warming center for families with no heat.
- Wildfire smoke: Air-quality emergency for vulnerable populations. Your hub provides clean filtered air with HEPA systems running on solar+storage.
The pattern: your hub becomes the place neighbors can count on when the grid fails.
Frequently asked questions
Do we need formal hub designation?
Not strictly required, but designation often helps with stacking grant funding. If your state, county, or city has a resilience hub designation program, get on it.
How much does battery storage add to system cost?
Storage roughly doubles total project cost vs. solar alone. With our recoverable grant, this is still zero upfront, payments may be slightly higher, but storage value during outages is hard to overstate.
What kind of battery technology?
Lithium iron phosphate (LFP) is the current standard for commercial nonprofit hubs, long lifespan, safe chemistry, established warranties. Tesla, Enphase, Generac, and others all make products in this space.
Can we add storage to existing solar?
Sometimes, depends on your existing inverter and electrical infrastructure. We'll review your specific situation.
