Eversource – Sudbury to Hudson Transmission Reliability Project

filing today, April 20, 2017

Dear Mr. Moses,

I am writing to let you know that we plan to file our proposed Sudbury to Hudson Transmission Reliability (Project) Petition with the Massachusetts Energy Facilities Siting Board (EFSB) today, April 20. The Project is a proposed 115-kV transmission line that connects Eversource’s Sudbury Substation, passing through Sudbury, Marlborough, Stow and Hudson, to Hudson Light & Power’s substation on Forest Avenue in Hudson.

The Project is a vital part of the Greater Boston and New Hampshire Solution, a set of transmission projects undertaken by Eversource and National Grid that address system-wide electric reliability and capacity needs, as determined by the independent power system operator for New England, ISO-New England.

During the Project planning stages, we proactively reached out to the local communities, municipal officials, community groups and other stakeholders to gather feedback on the Project. We held public open houses, community meetings and stakeholder discussion sessions, responded to questions, and listened to concerns. We took that feedback to heart and carefully considered all comments and suggestions received. We conducted additional engineering and constructability reviews to determine what changes were feasible, balancing a variety of factors, including system reliability, community impacts, the environment, and cost — while meeting our obligation to reliably serve our customers.

Based on feedback received and our subsequent feasibility analysis, we have altered our “preferred” Project route design to an all underground line along the MBTA property, with the remaining portion underground in the streets in Hudson.

Throughout each phase of the Project’s application, approval process and construction, we will continue to update our Project website on Eversource.com and promptly respond to stakeholder questions, concerns and comments from both our Project hotline (1-800-793-2202) and our Project email address (TransmissionInfo@eversource.com).

Please do not hesitate to contact me if you have any questions about our Project. I can be reached directly at office 508-305-6898 / mobile 508-808-2962 or joanne.oleary@eversource.com . I look forward to staying in close contact as we move forward with the EFSB process. Thank you.
