I am looking for an electric lines shapefile for Mexico and other Central and South American countries. Do you have any idea where I can get this data?
Check out the Topographic chart 1:50,000 freely available at inegi.org.mx it has the layer of electric lines (http://www.inegi.org.mx/geo/contenidos/topografia/default.aspx)

Not sure if this will have everything you are looking for but its free. You have to create an account with them before you can download though. Additionally, Power lines in the US are at least partially represented in the CENSUS "all lines" Tiger/line shapefile. Check out this link for other countries. http://data.geocomm.com/catalog/
