Connecticut regulators approve CL&P’s proposed 115-kV line construction

Connecticut state regulators have approved the request of Northeast Utilities Service Company (NUSCO), on behalf of its affiliate, Connecticut Light and Power (CL&P), to approve construction of the Stevenson to Frost Bridge to Baldwin 115-kV line, also known as the 1990 Line.

In its Aug. 14 decision, the state Public Utilities Regulatory Authority (PURA) said that it received on July 11 an application from NUSCO, on behalf of CL&P, requesting approval of the method and manner of construction of modifications to its Stevenson substation to Frost Bridge substation to Baldwin substation 115-kV transmission line.

The company is undertaking the project to improve safety and reliability by replacing aging structures that were built in the 1920s and 1930s.

PURA also noted that the project area is 20.5 miles long and materials to be used in the construction include: 173 tubular steel structures ranging in height from 70 feet to 180 feet above ground; five wood H-frame structures ranging in height from 36 feet to 48 feet above ground; and ceramic insulators.

The project includes construction in Watertown, Monroe and Waterbury in Connecticut, and it involves crossing of facilities of The Southern New England Telephone Company d/b/a AT&T Connecticut, Cablevision Systems Corporation, Comcast Cable of Connecticut and the Connecticut Department of Transportation.

The company filed copies of letters from each of those entities indicating that they have no objection to the proposed construction, PURA added.

Construction is scheduled to begin in September, PURA said, noting that all construction is in compliance with the current edition of the National Electrical Safety Code.

PURA said it “finds that the company satisfied all of the application requirements and grants approval of construction at the location cited” by the company.

PURA also granted approval to conduct commissioning tests and energize the facilities as necessary during construction, and following completion of the project.

The order further stated that the company is to advise PURA of the date on which construction is completed, and PURA will not require a field inspection.

NUSCO and CL&P are part of Northeast Utilities (NYSE:NU).
