Kake-to-Petersburg Transmission Line Intertie Project

 

The Kake-to-Petersburg Transmission Line Intertie (KPI) would connect the isolated electric system presently serving the city of Kake with SEAPA’s interconnected electric network, in or near Petersburg. An intertie transmission line from Kake to Petersburg has been discussed for many years and has been the subject of a number of studies dating back to the 1970s. More recent studies include the Southeast Alaska Intertie Study prepared in 2003 and a follow-on study of the KPI Project completed in 2005 and 2010, and subsequently updated in 2014. Several different routes have been evaluated as part of these studies with two primary route corridors identified in the 2005 KPI Project study and updates. Both corridors extend west across the Tongass National Forest from the Petersburg area to Kake on Kupreanof Island. The proposed transmission line would transmit 69 or 138 kilovolts (kV) and consist primarily of single wood pole structures.

The USDA Forest Service is the lead agency for an Environmental Impact Statement (EIS) that assesses the potential environmental impacts of the proposed project in accordance with the National Environmental Policy Act. The EIS describes and analyzes four alternatives, including a no-action alternative. All three action alternatives follow existing NFS system roads to the extent possible. No new roads would be built under any of the alternatives. Construction access in areas without existing roads would be via temporary shovel trails and matting panels, with helicopter support, as needed. Shovel trails would be temporary and decommissioned following project construction.

The following documents provide further insight and updates into the project:

 
 

Draft Environmental Impact Statement

A copy of the Draft EIS is available for review at the Petersburg Ranger District, other Tongass National Forest district offices, and the Forest Supervisor’s Office in Ketchikan. The document is also available for review online at: view link.
