A substation is a part of an electrical generation, transmission, and distribution system. Substations transform voltage from high to low, or the reverse, or perform any of several other important functions. Between the generating station and consumer, electric power may flow through several substations at different voltage levels.
The electrical energy generation mix in 2023 was 38.7% wind, 35.2% natural gas, 19.1% coal and 6.5% solar PV. Biomass, geothermal, hydroelectric, and petroleum each generated less than a 0.5% share combined. [1] Small-scale solar including customer-owned photovoltaic panels delivered net 702 GWh to New Mexico's electricity grid in 2023.
Electrical substation. Load balancing, load matching, or daily peak demand reserve refers to the use of various techniques by electrical power stations to store excess electrical power during low demand periods for release as demand rises. [1] The aim is for the power supply system to have a load factor of 1.
an electrical substation, with only one voltage level, whose only function are switching actions. a battery switch station, such as the ones used by the Better Place network. a railroad switching station. a telephone switching station
A traction substation, traction current converter plant, rectifier station or traction power substation (TPSS) is an electrical substation that converts electric power from the form provided by the electrical power industry for public utility service to an appropriate voltage, current type and frequency to supply railways, trams (streetcars) or ...
Large scale implementations this design strategy is seen in Toronto and Washington, DC where the electric operators put electrical substations in buildings that are disguised as houses in the neighborhoods (also known as fake houses). [12] [13] Another example is the 23-story AT&T equipment building at 10 South Canal Street in Chicago.
Electrical grid and power plants in the US. The United States is home to a wide variety of power stations. The list below outlines power stations of significance by type, or by the state in which they reside.
The IEEE 693: Recommended Practice for Seismic Design of Substations. [ 1 ] is a Institute of Electrical and Electronics Engineers standard. This standard is recognized also by American National Standards Institute , and is used mainly in the American Continent.
