Risk: Medium Substation Operational

Dewar Street Substation - 115 kV Electrical Substation in the United States

United States

Overview

Dewar Street Substation is an operational electrical substation in the United States, operating at 115 kV. It plays a role in regional grid stability and power distribution.

Dewar Street Substation is an operational electrical substation located in the United States, with coordinates 42.308785, -71.055098. Operating at a voltage of 115 kV, it is classified as a high-voltage substation, critical for stepping down transmission-level power for local distribution. The facility is part of the broader North American power grid, which is regulated by NERC reliability standards and FERC oversight for transmission assets. The substation's 115 kV voltage level indicates it serves as a key node in the regional electrical infrastructure, likely connecting transmission lines to distribution networks. In the United States, substations of this scale are typically equipped with modern switchgear and automation systems compliant with ISO/IEC 61850 standards to ensure reliable operation. The facility's location near urban areas suggests it supports dense population centers or industrial zones. Environmentally, the substation's operation is subject to stringent regulatory frameworks to minimize electromagnetic field impacts and ensure safe integration with surrounding land use. Its role in grid stability is significant, as it facilitates efficient power transfer and helps maintain voltage levels within acceptable limits. The facility's operational status underscores its ongoing contribution to reliable electricity supply in the region.

Environmental context

The substation's 115 kV operation places it in a medium-voltage class, typically associated with urban or suburban distribution networks. Its location in a densely populated area requires careful management of electromagnetic fields and noise, with compliance to local zoning and environmental regulations. The facility's age and technology level influence its environmental footprint, with modern substations incorporating SF6-free insulation and low-loss transformers to reduce emissions.

Frequently asked questions

Dewar Street Substation is located in the United States at coordinates 42.308785, -71.055098, likely in the Boston area given the latitude and longitude.

Dewar Street Substation operates at 115 kV, a common voltage level for subtransmission and distribution substations in the United States.

A 115 kV substation typically steps down high-voltage transmission power (e.g., 230 kV or higher) to lower voltages for local distribution, serving industrial, commercial, and residential customers.

Substations in the United States are regulated by NERC reliability standards for grid stability and FERC for interstate transmission. Local utilities must also comply with state public utility commission rules and ISO/IEC 61850 for automation.

Substations like Dewar Street provide voltage regulation, switching, and protection functions that isolate faults and maintain stable power flow, reducing outage risks and supporting overall grid resilience.
