Description: These data represent operable electric generating plants within the vicinity of the U.S. coastline by energy source. This includes all plants that are operating, on standby, or short or long-term out of service with a combined nameplate capacity of 1 megawatt or more. The presence of a facility may indicate that power transmission infrastructure exists nearby. The absence of a facility or lack of sufficient capacity at a facility in a given area may be an important characteristic in future energy planning activities.
