There is a good article in the September issue of Transmission & Distribution World titled Customers Access Online Outage Data. It was written by Barry Owens of SECO Energy. In case you missed it, Barry also gave the featured Customer Presentation at the recent Smallworld 2007 Americas Users Conference (presentations are here).
This is a project that I had heard about before and one of the things I had wondered was: "in a power outage situation, how will affected customers have the power to run their computers to check their outage status online?". Barry answers that question (and many others) in a well written presentation of their project.
Congratulations also to Peter Manskopf at GE for leading this successful project.
