Overview
Tiana Substation is an operational electrical substation in New York, United States, owned by Long Island Power Authority. It operates at 69 kV, serving the Long Island region.
Tiana Substation is an operational electrical substation located in New York, United States. Owned by Long Island Power Authority (LIPA), it is a key component of the region's electrical infrastructure, stepping down transmission voltage for local distribution. The substation operates at 69 kV, a common voltage level for sub-transmission and distribution substations in the US. As part of the US electrical grid, Tiana 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 to ensure grid stability and safety. Located on Long Island, the substation supports a densely populated area with high electricity demand. Its role is critical for maintaining reliable power supply to residential, commercial, and industrial customers. The facility contributes to grid resilience and helps integrate distributed energy resources, aligning with New York's energy transition goals.
Environmental context
The substation's location on Long Island places it in a coastal environment with exposure to severe weather events such as hurricanes and nor'easters. These conditions necessitate robust infrastructure to withstand storms and prevent outages. The facility's voltage level and urban setting imply a focus on reliability and minimal environmental footprint, with potential measures like oil containment systems and wildlife protection.
Frequently asked questions
Tiana Substation is located in New York, United States, on Long Island. Its approximate coordinates are 40.8734° N, -72.5314° W.
Tiana Substation operates at 69 kV (69,000 volts), which is a typical voltage for sub-transmission and distribution substations in the United States.
Tiana Substation is owned by Long Island Power Authority (LIPA), a public utility that provides electricity to Long Island and the Rockaway Peninsula.
US substations must comply with NERC reliability standards for grid stability and FERC regulations for interstate transmission. Additionally, substations often follow IEEE and ISO/IEC 61850 standards for automation and communication.
A 69 kV substation typically steps down transmission voltage (e.g., 138 kV) to distribution voltage (e.g., 13.8 kV) for local delivery. It also provides switching, protection, and monitoring functions to ensure reliable power supply.
