Open source mapping of US high voltage electrical grid

Possibly of interest for network operators who have inter-city circuits, where the underlying carrier is something on OPGW fiber in high voltage lines.

These people seem to be making an effort at mapping out high voltage lines, hydroelectric dams, substations, etc.

Very cool, thanks, Eric.

I do think the data in OpenStreetMap is undervalued. Lots of stuff there and there are a few projects that exist to better visualize that data. is another using Open Street Map data.
