Berlin Eastside Substation - 115 kV Electrical Substation in Berlin, New Hampshire

Berlin Eastside Substation is an operational electrical substation located in Berlin, New Hampshire, United States. Operated by Eversource, a major utility in the Northeast, this facility plays a role in the regional transmission and distribution network. The substation operates at a voltage of 115 kV, which is a common sub-transmission level in the United States, typically serving industrial and residential loads. As part of the U.S. electrical infrastructure, this substation operates under the regulatory framework established by the Federal Energy Regulatory Commission (FERC) and the North American Electric Reliability Corporation (NERC). NERC's reliability standards ensure the stability and security of the bulk power system. The 115 kV voltage level places this facility in the medium-voltage range, often used for local distribution and interconnection with smaller industrial customers. Located in the town of Berlin, New Hampshire, the substation supports the local community's electricity needs. The region's cold winters and potential for extreme weather events underscore the importance of reliable electrical infrastructure. The substation's role in the grid contributes to the resilience and operational continuity of the area's power supply.

The substation is situated in a rural area of northern New Hampshire, characterized by forests and mountainous terrain. The local environment includes cold winters with heavy snowfall, which can pose challenges for electrical infrastructure such as ice accumulation on equipment. The facility's location away from dense urban areas reduces some environmental impacts, but its operation still involves electromagnetic fields and potential oil leakage from transformers. Proper maintenance and adherence to environmental regulations help mitigate these risks.
