Most states have multiple electric utilities, many small, some big. With these large numbers of companies, it can be hard to get a true overall status of the power grid in a particular area. This project collects information from over 800 Utilities into one place, with more being added all the time: Making this site the most complete source of power outage information currently available.

Most utilities put few resources behind their publicly facing OMSs (Outage Management Systems). They are focused on getting their customers reconnected, as they should be. However, this means that during big outage events where many people want to know the status of the power in a particular area, the utility’s OMS will can be overwhelmed if not completely unresponsive. Meanwhile PowerOutage.us has stands to heavy web traffic without faltering. Allowing people directly affected by an outage event and onlookers to stay informed and up to date. PowerOutage.us is one of the most reliable sources of power outage information available.

In addition, no utility releases detailed historical power outage information, so we store all the information we collect; Making this project the only source of detailed historical power outage information. While this historical data is not available dirrectly on the site, you can contact us for more information.

I created this system out of a fascination with watching power outage maps during big storms as a kid and unique datasets as an adult. I like working on interesting projects and for a while had wanted to build something big that others could use and find interest in.

Since I started this in 2016, it has grown way beyond what I could have ever hoped for, now as my full-time job, and even employing others. It continues to bring me great satisfaction in building something used by millions of people.

US Census Bureau: the geometry data for the detailed US maps.

MapBox: the code for drawing the detailed maps.

gadm.org: the geometry data for the UK maps.

Outage data will only be as accurate as the Utility reports it. We detect and adapt when a utility site breaks and/or reports inaccurate data but in some cases it is essentially impossible to discern the difference. During major events, We will be activly monitoring the status of many parts of PowerOutage.us including the data imports and will address any unhandled issues ASAP.

Many small companies do not report outage information online, and in these cases there is nothing we can do to collect this information. If your utility is one of these then you can help! Call them up, E-mail them, or reach out to them on social media and let them know you want to have them add a public outage reporting system.

If you have any questions, or see any issues on the site, please reach out to us!
