Overview
Emerald Street Substation is an operational electrical substation owned by Eversource in the United States. It operates at 115 kV, serving as a key node in the regional transmission grid.
Emerald Street Substation is an operational electrical substation located in the United States, owned and operated by Eversource, a major utility in the Northeast. The facility operates at a voltage of 115 kV, classifying it as a medium-voltage substation that plays a critical role in distributing power from high-voltage transmission lines to local distribution networks. As part of the U.S. electrical infrastructure, this substation operates under the regulatory framework of the North American Electric Reliability Corporation (NERC) and the Federal Energy Regulatory Commission (FERC). These bodies enforce reliability standards and oversee interstate electricity transmission. The substation likely includes modern switchgear and protection systems compliant with industry standards such as IEEE C37, ensuring safe and reliable operation. The substation's location in a region served by Eversource suggests it supports a mix of residential, commercial, and industrial loads. Its operational status indicates it is actively contributing to grid stability and power delivery. The facility's role in the local grid underscores its importance in maintaining reliable electricity supply to the surrounding community.
Environmental context
The substation is situated in a temperate climate region of the northeastern United States, where seasonal weather variations, including snow and ice storms, can impact grid reliability. Its location in a developed area means it is subject to urban environmental considerations such as electromagnetic field management and noise mitigation. The facility's design likely incorporates measures to minimize environmental impact, such as oil containment for transformers and wildlife protection features.
Frequently asked questions
