Path 62
Path 62 or the Eldorado - McCullough 500 kV Line is a short 500 kV power line linking Los Angeles Department of Water and Power's (LADWP's) McCullough substation to Southern California Edison's (SCE's) Eldorado substation in the Eldorado - Marketplace - McCullough substation complex just south of Boulder City, Nevada. Path 62 is part of The Western Electricity Coordinating Council's links of electrical intertie paths in the western United States. Like Path 61, this short, yet important 500 kV line allows for power flow to be rerouted on different 500 kV lines that make up the massive Path 46 transmission system when necessary. Power generated from Hoover Dam, and fossil fuel power plants in the Four Corners region is routed to this substation complex via many other 500 kV lines that connect to this substation complex.Route descriptions and tower designs are based on Google Earth images. Power transmission capacity The 500 kV line can transmit 2,598 MVA (3,000 amps) of elec ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Volt
The volt (symbol: V) is the unit of electric potential, electric potential difference (voltage), and electromotive force in the International System of Units (SI). It is named after the Italian physicist Alessandro Volta (1745–1827). Definition One volt is defined as the electric potential between two points of a conducting wire when an electric current of one ampere dissipates one watt of power between those points. Equivalently, it is the potential difference between two points that will impart one joule of energy per coulomb of charge that passes through it. It can be expressed in terms of SI base units ( m, kg, second, s, and ampere, A) as : \text = \frac = \frac = \frac. It can also be expressed as amperes times ohms (current times resistance, Ohm's law), webers per second (magnetic flux per time), watts per ampere (power per current), or joules per coulomb (energy per charge), which is also equivalent to electronvolts per elementary charge: : \text = \tex ...

Electric Power Transmission
Electric power transmission is the bulk movement of electrical energy from a generating site, such as a power plant, to an electrical substation. The interconnected lines that facilitate this movement form a ''transmission network''. This is distinct from the local wiring between high-voltage substations and customers, which is typically referred to as electric power distribution. The combined transmission and distribution network is part of electricity delivery, known as the electrical grid. Efficient long-distance transmission of electric power requires high voltages. This reduces the losses produced by strong currents. Transmission lines use either alternating current (HVAC) or direct current (HVDC). The voltage level is changed with transformers. The voltage is stepped up for transmission, then reduced for local distribution. A wide area synchronous grid, known as an "interconnection" in North America, directly connects generators delivering AC power with the same rela ...

Los Angeles Department Of Water And Power
The Los Angeles Department of Water and Power (LADWP) is the largest municipal utility in the United States with 8,100 megawatts of electric generating capacity (2021-2022) and delivering an average of 435 million gallons of water per day to more than four million residents and local businesses in the City of Los Angeles. It was founded in 1902 to supply water to residents and businesses in the Los Angeles and surrounding communities. In 1917, it began to deliver electricity to portions of the city. It has been involved in a number of controversies and media portrayals over the years, including the 1928 St. Francis Dam failure and the books ''Water and Power'' and ''Cadillac Desert''. History Private operators By the middle of the 19th century, Los Angeles's rapid population growth magnified problems with the city's water distribution system. At that time, a system of open, often polluted ditches, was reasonably effective at supplying water for agricultural production but was n ...

Electrical Substation
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. A substation may include transformers to change voltage levels between high transmission voltages and lower distribution voltages, or at the interconnection of two different transmission voltages. They are a common component of the infrastructure, for instance there are 55,000 substations in the United States. Substations may be owned and operated by an electrical utility, or may be owned by a large industrial or commercial customer. Generally substations are unattended, relying on SCADA for remote supervision and control. The word ''substation'' comes from the days before the distribution system became a grid. As central generation stations became ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Southern California Edison
Southern California Edison (or SCE Corp), the largest subsidiary of Edison International, is the primary electricity supply company for much of Southern California. It provides 15 million people with electricity across a service territory of approximately 50,000 square miles. However, the Los Angeles Department of Water and Power, San Diego Gas & Electric (SDG&E), Imperial Irrigation District, and some smaller municipal utilities serve substantial portions of the southern California territory. The northern part of the state is generally served by the Pacific Gas & Electric Company of San Francisco. Other investor-owned utilities (IOUs) in California include SDG&E, PacifiCorp, Bear Valley Electric, and Liberty Utilities. Southern California Edison (SCE) still owns all of its electrical transmission facilities and equipment, but the deregulation of California's electricity market in the late 1990s forced the company to sell many of its power plants, though some were probably sold ...

WECC Intertie Paths
The Western Electricity Coordinating Council (WECC) coordinates a number of high voltage power links in western North America.https://www.wecc.biz/Reliability/TAS_PathReports_Combined_FINAL.pdf These links, known as WECC Intertie Paths, are not necessarily single transmission line, rather they are interties between various areas. These areas can be quite distant, such as Path 65 between The Dalles, Oregon and Los Angeles, California or short such as Path 62 between Southern California Edison's Eldorado and LADWP's McCullough substations. These are currently numbered from 1 to 81, with a few numbers intentionally omitted. Table of paths Since the interties may consist of multiple power-lines, the maximum voltage used is shown in the table below. Some of the links such as Path 65, the Pacific DC Intertie The Pacific DC Intertie (also called Path 65) is an electric power transmission line that transmits electricity from the Pacific Northwest to the Los Angeles area using HVDC, ...

Path 61
Path 61 or the Lugo - Victorville 500 kV Line is a relatively short AC 500 kV power line that runs from Southern California Edison's (SCE) Lugo substation southwest of Hesperia to Los Angeles Department of Water and Power's (LADW&P) Victorville substation north of Victorville, California. Path 61 is part of the Western Electricity Coordinating Council's links of electrical intertie paths in the western United States.This line is an important connection between two out of the four parts that make up the massive Path 46 transmission system in southeast California since the line allows power flow to be rerouted on Path 46 when necessary. Half of the length of the 500 kV power line is owned by SCE to the south and LADW&P to the north. The entire line is located in the Mojave Desert and the High Desert regions of California.Route descriptions and tower designs are based on Google Earth images.

Hoover Dam
Hoover Dam is a concrete arch-gravity dam in the Black Canyon of the Colorado River, on the border between the U.S. states of Nevada and Arizona. It was constructed between 1931 and 1936 during the Great Depression and was dedicated on September 30, 1935, by President Franklin D. Roosevelt. Its construction was the result of a massive effort involving thousands of workers, and cost over one hundred lives. It was referred to as Hoover Dam after President Herbert Hoover in bills passed by Congress during its construction; it was named Boulder Dam by the Roosevelt administration. The Hoover Dam name was restored by Congress in 1947. Since about 1900, the Black Canyon and nearby Boulder Canyon had been investigated for their potential to support a dam that would control floods, provide irrigation water and produce hydroelectric power. In 1928, Congress authorized the project. The winning bid to build the dam was submitted by a consortium named Six Companies, Inc., which began ...

Four Corners
The Four Corners is a region of the Southwestern United States consisting of the southwestern corner of Colorado, southeastern corner of Utah, northeastern corner of Arizona, and northwestern corner of New Mexico. The Four Corners area is named after the quadripoint at the intersection of approximately 37° north latitude with 109° 03' west longitude, where the boundaries of the four states meet, and are marked by the Four Corners Monument. It is the only location in the United States where four states meet. Most of the Four Corners region belongs to semi-autonomous Native American nations, the largest of which is the Navajo Nation, followed by Hopi, Ute, and Zuni tribal reserves and nations. The Four Corners region is part of a larger region known as the Colorado Plateau and is mostly rural, rugged, and arid. In addition to the monument, commonly visited areas within Four Corners include Monument Valley, Mesa Verde National Park, Chaco Canyon, Canyons of the Ancie ...
