2008, August 7: Petition for crossing Merrimack River, reliability upgrade; "In order to continue to meet the reasonable requirements of service to the public, PSNH has determined it is necessary to upgrade the A-152 line conductors to increase the power transfer capability of the line. This need is a result of load growth in the central part of New Hampshire. The entire length of the A- 152 line between Keene and Swanzey is constructed of 477 ACSR. The remainder of this line, between the Swanzey substation and Vermont Yankee generating plant in Vermont, is 795 ACSR. This project will remove all of the 477 ACSR and replace it with 1590 ACSR between the Emerald Street and Swanzey Substations. Upgrading this portion of the A-152 line will allow PSNH to continue to provide reliable electric service to its customers in this area of the State"
