Eversource planning 115-kV transmission line in Boston area

NSTAR Electric d/b/a Eversource Energy has filed two related petitions with the Massachusetts Energy Facilities Siting Board and the Department of Public Utilities seeking to build a four-mile-plus stretch of 115-kV transmission line in the Greater Boston area.

The 4.2-mile, 115-kV project would be a combination overhead-and-underground transmission line. The stretch would be built in the West Roxbury section of Boston and the Towns of Dedham and Needham.

The company plants to interconnect the new line with two existing substations (Eversource’s Baker Street Substation in West Roxbury (Station #110)) and Needham Substation (Station #148).

The project is proposed in order to address needs on the existing transmission system in the area at peak load levels.

The Siting Board will conduct a public comment hearing on Tuesday, Sept. 27, at the Needham Town Hall.

Pursuant to an Order issued by the chairman of the Department of Public Utilities in August, the two project-related petitions have been consolidated before the Siting Board under the docket number EFSB 16-02/D.P.U. 16-77.

The Siting Board will review the company’s filing to determine whether the project would provide a reliable energy supply with a minimum impact on the environment at the lowest possible cost.

The company’s preferred route between the Baker Street Substation and the Needham Substation is 4.2 miles, including approximately 1.6 miles of overhead line construction parallel to the Massachusetts Bay Transit Authority (MBTA) commuter rail tracks (Needham Line) in Boston, Dedham and Needham, and 2.6 miles of underground cable construction primarily in public roads in Needham.

Eversource has also identified an alternative route of 4.5 miles, including the same 1.6 miles of overhead line construction proposed for the company’s preferred route and approximately 2.9 miles of underground cable construction primarily in public roads in Needham.

There would be no significant substation work for the project at either the Baker Street Substation or the Needham Substation.

Written comments regarding the proposed Project may be filed with the Siting Board until 5 p.m. on Tuesday, Oct. 11.

Anybody wishing to submit written comments should send them by email or email attachment to: (1) dpu.efiling@state.ma.us and (2) kathryn.sedor@state.ma.us.

Alternatively, written comments may be sent by U.S. mail to M. Kathryn Sedor, Esq., Energy Facilities Siting Board, One South Station, Boston, Massachusetts, 02110.

Sedor is the presiding officer in the case. Any party wishing to intervene in the case should file their petition with Sedor by close of business on Oct. 11.
