RNI (Renewable Energy Installations)

This page is designed to assist developers of Offshore Renewable Energy Installations (OREI) with the design and planning of these projects in Oregon, Washington, Idaho and Montana. The term OREI is used by the Coast Guard to describe any individual structure or apparatus placed in the navigable waters of the United States that creates electricity by using sources other than oil or gas. Examples include wind farms and hydrokinetic apparatus such as buoys or wave and current turbines.

The Coast Guard oversees two aspects of OREI projects:

1.  Risk Assessment: 

Reviewing the applicant's Navigation Safety Plan to determine if the installation will pose potential adverse impacts to the users of the waterway. This is accomplished by conducting a Risk Assessment.

Risk Assessments are conducted by the USCG Sector Puget Sound Waterways Management Branch office located in Seattle for projects north of Grays Harbor including the Strait of Juan De Fuca and Puget Sound as well as the northern part of Idaho and all of Montana.

Risk Assessments are conducted by the USCG Sector Columbia River Waterways Management Branch office located at Marine Safety Unit Portland for project in Grays Harbor and south to the California boarder including the Columbia and Snake Rivers as well as southern Idaho.

2.  PATON Requirements:

Determining if the installation will require Private Aids to Navigation (PATON), which include the use of navigation lights and/or regulatory signs as well as buoys. These are used to warn mariners of the presence of the installation. For more information regarding what a PATON is click here.

USCG District 13 Waterways Management Branch located in Seattle is responsible for the permitting of Private Aids to Navigation (PATON) in Oregon, Washington, Idaho and Montana.
