Overview
Oswald Substation is an operational 115 kV substation owned by Eversource in the United States. It plays a key role in regional grid stability and power distribution.
Oswald Substation is an operational electrical substation located in the United States, owned and operated by Eversource. With a voltage level of 115 kV, it is classified as a medium-voltage substation, typically serving distribution and sub-transmission functions within the power grid. The facility is part of the broader electrical infrastructure that supports reliable electricity delivery to residential, commercial, and industrial customers. Operating under the regulatory framework of the United States, the substation adheres to standards set by the North American Electric Reliability Corporation (NERC) for grid reliability and security. As a transmission-level asset, it is subject to Federal Energy Regulatory Commission (FERC) oversight for interstate electricity markets and reliability. The 115 kV voltage level is common for sub-transmission networks that connect bulk power systems to local distribution networks. The substation's location in the northeastern United States places it within a region with a mature electrical grid, high population density, and significant energy demand. Eversource, the owner and operator, is a major utility serving customers in Connecticut, Massachusetts, and New Hampshire. Oswald Substation contributes to grid resilience and supports the integration of renewable energy sources, helping to maintain stable power supply for the surrounding communities.
Environmental context
The substation is situated in a region with a mix of urban and rural landscapes, where electrical infrastructure must balance reliability with environmental considerations. The 115 kV voltage level indicates a moderate footprint, with typical environmental impacts limited to land use for equipment and access roads. The facility operates under U.S. environmental regulations that manage electromagnetic fields, oil containment, and wildlife protection. Its role in grid stability supports the integration of renewable energy, reducing reliance on fossil fuels.
