Battery Storage (1439)

Battery Storage is a 151.3 MW battery interconnection project in Hampshire, Massachusetts with a current status of withdrawn. It is proposed to connect at The Primary Point of Interconnection will be a new 3-breaker ring bus located on the IC’s property which connects to Eversource T line 1113 (Fairmont to Tillson) at 115 KV. The break in the line will take place 4.52 miles from the Fairmont Substation and 10.55 miles from the Tillson substation. The distance from the line break to the 3-breaker ring bus located on the IC’s property will be approximately 0.22 miles. The approximate latitude/longitude coordinates of the 3-breaker ring bus is 42.249111, -72.533752. The Alternative Point of Interconnection will be a new 3-breaker ring bus located on the IC’s property which connects to Eversource T line 1134 (Fairmont to Five Corners) at 115 KV. The break in the line will take place 4.52 miles from the Fairmont Substation and 0.11 miles from the Five Corners Substation. The distance from the line break to the 3-breaker ring bus located on the IC’s property will be approximately 0.22 miles. The approximate latitude/longitude coordinates of the 3-breaker ring bus is 42.249111, -72.533752..
