Overview
Davisville Substation is an operational electrical substation in Rhode Island, United States, owned by Rhode Island Energy. It operates at voltage levels of 115 kV and 34.5 kV, serving the local grid.
Davisville Substation is an operational electrical substation located in Rhode Island, United States. Owned by Rhode Island Energy, the facility plays a key role in the regional power distribution network, stepping down transmission voltages for local use. The substation is a medium-scale asset typical of the US electrical infrastructure, which is regulated by NERC reliability standards and FERC oversight. The substation operates at voltage levels of 115 kV and 34.5 kV, indicating its role in both sub-transmission and primary distribution. Such voltage levels are common for substations serving suburban or industrial areas, balancing capacity with safety. The facility is part of Rhode Island Energy's network, which serves over 500,000 customers across the state. As part of the US electrical grid, Davisville Substation contributes to grid stability and reliability in the region. Its location in Rhode Island places it within the ISO New England control area, which coordinates wholesale electricity markets and ensures system reliability. The substation's operational status supports local communities and businesses by maintaining consistent power supply.
Environmental context
The substation is located in a suburban area of Rhode Island, near residential and commercial zones. Its operation involves electromagnetic fields and potential noise from transformers, which are managed through standard mitigation practices. The site's proximity to Narragansett Bay may require attention to stormwater runoff and oil containment to protect local waterways. Vegetation management around transmission lines is also typical to prevent outages.
