Item Identification

Title: Power Plants
Status: Completed
Revision Date: 2022-02-16

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.


To support ocean planning activities pursuant to the Executive Order Regarding the Ocean Policy to Advance the Economic, Security, and Environmental Interests of the United States, the Energy Policy Act, the National Environmental Policy Act, the Rivers and Harbors Act, and the Coastal Zone Management Act.
