Northeast Utilities Service Company (NUSCO), on behalf of its affiliate, Connecticut Light and Power (CL&P), is asking the Connecticut Public Utilities Regulatory Authority (PURA) to approve the method and manner of construction as well as to allow the company to energize the Stevenson to Frost Bridge to Baldwin 115-kV line, also known as the 1990 Line.
“This project construction will involve the daily outage and re-energizing of the circuits as the proposed work is being performed,” the company said. “For this reason CL&P seeks permission to energize during and after the construction period.”
The purpose of the project is to improve the circuit’s reliability and provide increased safety to line workers and the general public by replacing aging structures that were built in the 1920s and 1930s.
The proposed construction will occur between the Stevenson, Frost Bridge and Baldwin substations in the Connecticut municipalities of Monroe, Oxford, Middlebury, Waterbury and Watertown within the existing CL&P right of way.
The entire length of the project is about 20.5 miles, with the total project area divided into three sections of about 10.5 miles – Stevenson substation to Baldwin Junction – 6.9 miles – Baldwin Junction to the Frost Bridge substation – and 3.1 miles – Baldwin Junction to the Baldwin substation.
“The project will construct 148 single circuit tubular steel monopoles, 25 double circuit tubular steel monopoles, and [five] single circuit wood H-frames,” the company added.
The project will cross over or under circuits and facilities of other utilities or municipalities, the company said, adding that the project will affect the facilities of AT&T, Cablevision, Comcast and the Connecticut Department of Transportation (CTDOT).
Letters of no objection from AT&T, Cablevision and Comcast were included in the filing. To date, CL&P has not received a letter of no objection from the CTDOT but will submit it in a supplemental filing upon receipt, according to the filing.
Project construction is scheduled to begin on Sept. 1, with completion expected by Dec. 31, 2014. The project does not include underground line construction.
Among other things, the company said that the Connecticut Siting Council, in a June 13 meeting, ruled that a certificate of environmental compatibility and public need is not required.
