About PowerLockdown

PowerLockdown helps households prepare for long power outages, from a 72-hour storm outage to 90 days or more without the grid: the kind caused by hurricanes, ice storms, wildfire power shutoffs, severe geomagnetic storms and a grid under growing strain. We publish practical preparation steps and the sourced data behind them.

What we do

• Score how many days a home could last without the grid with the readiness score, which runs in your browser and is documented on its method page.
• Summarize where the grid is most stretched, using NERC's published reliability assessments (our Grid Risk Outlook).
• Show live space-weather and weather-alert conditions from NOAA and the National Weather Service.
• Publish a printable blackout checklist and plain-language guides built on named public sources such as the EIA, Ready.gov (FEMA), CDC, CPSC and FDA.
• Recommend research-based gear picks, based on manufacturer specs and published data.

What we don't do

• We do not test products, and we never claim to have tested them.
• We do not provide outage alerts for your address. For live outage information, follow your utility and local emergency officials.
• We are not affiliated with any government agency, grid operator or utility.

What is on the site

PowerLockdown has two sections:

• Outage prep: grid-risk summaries, the printable blackout checklist and seasonal guides.
• The Blackout Kit: water, food, heat, light, comms and medical supplies, with a household worksheet. This section was previously published on EnergySavingsAI.

Backup power sizing and gear guides (power stations, generators, solar kits and transfer gear) are published on our sister site, BackupPowerAI, which has the sizing calculator.
