How resilient is your home grid?
VoltOutpost scores major U.S. cities on four factors that shape household energy resilience: solar recharge potential, seasonal solar consistency, disaster exposure and electricity affordability.
Four inputs. One comparable benchmark.
The index is designed as a standardized comparison—not a claim that any location or home will remain powered during an outage.
Built from updateable public data.
The scheduled GitHub workflow refreshes available PVWatts solar output, EIA residential electricity prices and FEMA disaster-declaration exposure, then rebuilds every city and state page.
Solar production
Standardized 10 kW roof-mounted solar simulations provide annual output and month-to-month consistency.
Disaster exposure
County-level federal disaster declaration history is used as a simple, transparent exposure proxy—not as an outage prediction.
Electricity prices
Residential retail electricity prices provide the cost component and refresh when newer data are available.
Use the index in your own work.
