Overview
Stony Brook Substation is an operational electrical substation owned by Long Island Power Authority in New York, United States. It operates at 69 kV, serving the local grid.
Stony Brook Substation is an operational electrical substation located in New York, United States. Owned by Long Island Power Authority, it operates at a voltage of 69 kV, classifying it as a medium-voltage substation within the regional transmission and distribution network. The facility plays a key role in stepping down power for local distribution to residential and commercial customers on Long Island. As a substation under the jurisdiction of the United States, it operates within the regulatory framework of the North American Electric Reliability Corporation (NERC) reliability standards and the Federal Energy Regulatory Commission (FERC) for transmission-level assets. The 69 kV voltage level is typical for subtransmission systems that connect bulk power sources to distribution networks. The facility's equipment likely includes circuit breakers, transformers, and switchgear designed to ensure grid stability and safety. The environmental context of Stony Brook Substation is shaped by its location on Long Island, a densely populated coastal region. The substation supports the electrical infrastructure for nearby communities and critical facilities. Its operation is subject to local environmental regulations concerning electromagnetic fields, noise, and stormwater management. The facility's role in maintaining reliable power supply is essential for the region's economic activity and quality of life.
Environmental context
Located on Long Island, New York, the Stony Brook Substation operates in a coastal urban environment. The region's dense population and critical infrastructure demand high grid reliability. The substation's 69 kV voltage level places it in a subtransmission role, balancing local distribution needs with bulk power transfer. Environmental considerations include electromagnetic field management, noise mitigation, and stormwater runoff control to protect nearby ecosystems.
Frequently asked questions
Stony Brook Substation is located in New York, United States, specifically on Long Island. Its coordinates are approximately 40.917954 N, -73.129899 W.
Stony Brook Substation is owned by Long Island Power Authority (LIPA), which also operates the facility. LIPA is a public benefit corporation providing electricity to Long Island.
Stony Brook Substation operates at 69 kV (69,000 volts), which is a common subtransmission voltage level in the United States, used to distribute power from higher-voltage transmission lines to local distribution networks.
In the United States, substations must comply with NERC reliability standards for grid stability and FERC regulations for transmission assets. Additionally, equipment often follows IEEE and ISO/IEC 61850 standards for substation automation.
A 69 kV substation serves as a subtransmission facility, stepping down voltage from higher transmission levels (e.g., 138 kV or 230 kV) for distribution to local feeders. It helps balance load and ensures reliable power delivery to residential and commercial customers.
