Hurricane Sandy: power outage tracking and mapping

Hurricane Sandy hit the US East Coast earlier this week, knocking out power to more than 8 million subscribers. The damage to the infrastructure was so severe that it's expected to take more than a week to bring service back.

Here are a few of the better projects online to track the progress of service restoration.

NY Times

The New York Times is tracking power outages and restoration for the Con Edison service. They're pulling county by county data from the utility company web site and tracking and visualizing it over time. More detailed reporting also covers surrounding states, including hard-hit New Jersey and Long Island. Sample graphic:

Con Edison Charts

Another tracker for Con Edison outage information has been done by Cameron Cundiff (@ckundo) from Pivotal Labs. This one features source code on Github and a chart on

iFactor’s Storm Center

The "Storm Center" application from iFactor powers the web sites for a number of the larger utilities affected by Hurricane Sandy. In Storm Center put to the test during Sandy, they discuss how the systems held up in the storm. Some 3,500,000 visits were logged to the mapping pages, and of those 20-50% were from mobile devices.

NYC Power Status

Does NYC have power? A simple page shows current restoration status by borough. "Con Edison is working on it." See

The trouble with utility outage tracking

The hardest part about tracking utility outages across a broad area is that there's wide variety in how each utility reports outages. It would be useful to a lot of organizations to have a single map covering the whole storm area, but instead we have little pieces of a big picture.
