J136S Tap and I135/J136S Mainline

Project

About the Project

J136S Tap Line:

The J136S Tap Line Rebuild Project will improve about 3.1 miles of the existing J136S Tap Line. The line will stay in service as a 115-kilovolt transmission line during the work. The project includes several upgrades. The current line has 42 structures and will be rebuilt with modern steel structures. The new line will be moved about 40 feet east of its current location. Two structures will be removed by re-positioning the lines, leaving a total of 40 structures once the work is complete. The project also includes replacing existing conductors and adding optical ground wire within the current right of way. Vegetation management will increase the maintained area in the right of way by 40-50 feet. The work will also include building new and improved access routes.

Mainline:

As one of the regional electricity providers, National Grid regularly upgrades its equipment to provide reliable electric service to homes and businesses. We are improving part of the electric transmission system to increase reliability, improve communication, and strengthen long-term performance. The project includes updating existing transmission structures and installing new optical ground wire along about 8.1 miles of the I135S/J136S transmission line. The work will replace three existing structures with three H-frame structures, add one new H-frame switch structure, replace some power lines, and install optical ground wire within the current right-of-way. When needed, the project will also include access-road improvements and vegetation management.

Phases of Construction

  1. Site Preparation

    The first step is clearing trees and brush. This work allows construction crews to safely build access roads and remove trees that could fall onto the power lines.

  1. Environmental Controls

    Next, steps are taken to protect the area during construction. These may include placing mats, silt fences, and containers for construction materials.

  1. Transmission Line Rebuilding

    New foundations and structures are installed, along with fiber-optic cable and new wires. Old structures are removed, and new wires are energized. Crews use heavy equipment, including cranes.

  1. Restoration

    Once construction is finished, crews will restore the work areas to their original condition as much as possible, unless permits or land agreements specify otherwise.

    Weather Icon

    The J136S Tap Line construction work will help meet future power needs. Adding optical ground wire will improve communication between substations and make the line more resistant to severe weather, such as lightning. The project will also replace damaged wooden structures with stronger steel structures.
