72 Hours Into the Event – Nearly 2 Million Customers in the Dark from June 29th Derecho


This has definitely been a significant weather event from the Chicago area through the Upper Midwest and into the Mid-Atlantic.  Throughout the evening of June 29th and into the early morning hours of June 30th, as many as 4 million power customers from Indiana to Virginia lost power as a result of a phenomenon called a derecho.  A derecho is a widespread damaging wind event that lasts for many hours and spans hundreds of miles.  With temperatures in the upper 90’s to near 100 in many of these areas over the coming days, it will be imperative for communities to work together to address the needs.  Please check in on those who are particularly vulnerable to extreme heat.  Remember that each customer without power represents a business, facility or a household, and that many more people are impacted.  Please stay safe, and bring the best out in your communities.  This is an opportunity to help one another recover.

Nearly 2 million customers still in the dark.  Numbers are improving slightly, down slightly from the more than 4 million customers out overnight, but will likely contin`ue for several days.

  1. We were told today that West Virginia has 85% of residents are without power. FEMA is sending generators for nursing homes and hospitals. There are very few gas stations that are operating, too, and the ones that do have a hard time keeping their tanks filled! They are estimating it will take until July 6th to restore all power.

  2. Good summary, thanks.

    I have a list of power outage maps here, organized by state

    http://vielmetti.typepad.com/vacuum/2011/06/power-outage-maps.html

    A few more for your list:

    6200 out in Indianapolis, Indianapolis Power and Light Co. http://apps.iplpower.com/outages/outagemap.aspx

    4291 out in Kentucky, LG&E/KU http://stormcenter.lge-ku.com/default.html

    I wish that somehow power companies could get together and produce a standard format for outage mapping so that it was easy to build an aggregated national map – that could save a lot of time and improve situational awareness for storm tracking.
