The 115kV Connections would extend from the new Schaghticoke Transmission Switching Station (“Station”) and tie into the existing 115kV Mohican –Luther Forest Line 3 and its existing 115kV Battenkill –Eastover Road Line 10 (the “Project”). The Station will be located south of the Hoosic River and north of New York State Route 67 in the Town of Schaghticoke, Rensselaer County, New York (see Figure 1). 1.2 Need for Project The Project is necessary to provide system reliability to the electric utility end users and to support demand from the expansion of the Global Foundries computer chip fabrication facility at the Luther Forest Technology Campus. Table 1 below presents a summary of the scope of work involved in the Project and Figure 2 contains mapping that includes Project structure locations. No grading is proposed for the 115kV Connections and, therefore, the locations of the new structures will not be impacted.
