charging station announcements are almost becoming commonplace (keyword: almost), but not so much that we aren't happy to welcome one more. This week NRG Energy unveiled it's first eVgo branded "Freedom Station" at a Dallas Walgreens, and aims to pepper the map with a total of 60 such units by Labor Day. Each eVgo freedom station will pack both a quick charging 480V AC/DC converter (juicing up a Nissan Leaf to 80 percent in about 30 minutes), as well as a 240V Level 2 charger (netting 25 miles of "go" per charging hour). NRG plans to cover the Dallas / Fort Worth and Houston areas with 120 of these guys by the end of 2012. Like others before it, the eVgo network plans to follow a subscription model -- with the premiere plan ($89 a month on a three year contract) not only covering the cost of usage at eVgo charging stations, but that of electricity used at your home charging dock, too. Toss in a handful of generous EV owners rocking PlugShare, and Dallas has the makings of a low-emissions wonderland.
