Battery Storage (1452)

Battery Storage is a 151.3 MW battery interconnection project in Worcester, Massachusetts with a current status of withdrawn.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 (Lat, long: 42.322909, -71.984654) which connects to T line A127-4 at 115 KV (Barre Substation to Paxton Substation). The POI distance following the T Line is approximately 7.66 miles from the Barre Substation and approximately 3.04 miles from the Paxton Substation. The Alternative Point of Interconnection will be a new 3-breaker ring bus located on the IC’s property (Lat, long: 42.322909, -71.984654) which connects to T line B128-5 at 115 KV (Treasure Valley Substation to Barre Substation). The POI distance following the T Line is approximately 0.2 miles from the Treasure Valley Substation and 7.66 miles from the Barre Substation..
