Use the map below to see if there is 3-phase power available to a specified address. Enter an address in the ‘Find Address’ bar nbsp; Zoom into the area of interest. If there is 3 phase available it will appear as a thick green line. This map is based on plant records and does not perfectly represent the presence of energized 3 phase power. It is imperative that the actual availability be confirmed with a Green Mountain Power representative. The lines take a few seconds to paint, please be patient.
