what percentage of las vegas' total electrical supply comes from the hoover dam?

Question

or any general hoover daminfo welcome.

Answer 1

The Strip in Las Vegas gets about 15.5% of its power from Hoover Dam. Most of the power goes to California and Arizona.

According to Wikipedia: http://en.wikipedia.org/wiki/Hoover_Dam#Power_distribution
“The seventeen main turbine-generator combinations at this powerhouse generate a maximum of 2,074 megawatts of hydroelectric power.

Nevada gets 23.3706% of the power output from the Hoover Dam.”
Therefore Nevada gets 484 megawatts (484,706,244 watts) of power from Hoover Dam, if the dam is operating at peak power production.

According to Wikipedia: http://en.wikipedia.org/wiki/Nevada_Power_Company
"Hoover Dam provides about 225 megawatts to the Nevada Power system. Contrary to popular opinion, Las Vegas does not get most of its power from the dam. It also does not get most of the power produced at the dam. California and Arizona get most of the dam's generated power."

·So the electrical power provided to the State of Nevada varies between 225 and 484 megawatts of power.

According to: www.skygaze.com/content/facts/energy.shtml
“Over any given twenty four hour period, the fifty major hotels and gambling casinos in the Las Vegas area use 1.5 million kilowatt (150 megawatt) hours of electricity, enough to provide power for a city of some 35,000 inhabitants. The power used by these entertainment establishments simply to light their marquees could supply the electricity for more than 1,000 homes.”

·Therefore of the power provided to Nevada the Las Vegas strip uses 0.67% of the power provided by the Hoover Dam.
·Finally, Las Vegas gets 15.58% of its power from Hoover Dam

According to: http://www.desertusa.com/colorado/lm_nra/hoover/du_hoover.html
“Originally called Boulder Dam, this engineering marvel was re-named for Herbert Hoover, the 31st President of the United States. As a conservationist, he was a strong proponent of preserving our natural resources and protecting the nation's lands from misuse and from destruction by disastrous floods. As an engineer, he strongly supported construction of a high concrete dam on the Colorado River to control the river, and to provide irrigation water to the rich farmlands nearby, and a dependable supply of water for Southern California communities.
President Hoover advocated that the Boulder Canyon Project be self-supporting, financed entirely through the sale of hydroelectric power generated at the dam. He was personally involved in the pre-construction discussions concerning the location, feasibility and safety of the dam -- a dam of unprecedented height and weight and the key to control and regulation of the Colorado River.”

According to: http://www.pinkjeep.com/jeep-tours/lasvegas/hoover-dam-tour.shtml
The US 93 Bypass will take traffic that crosses the bridge and transfers it to a large single arch bridge. Hoover Dam Bypass project and construction of the nearly 2000-foot-long bridge spanning over 900 feet above the river."

According to: http://www.bechtel.com/sphovr.htm
"Hoover Dam represented the greatest challenge of Bechtel’s history in the early 1930s. It was the largest civil engineering project in the history of the United States, and a dam that would control one of the most powerful rivers in the world. Standing 726 feet high, 1,200 feet across the crest, and 660 feet thick at its base, Hoover Dam placed huge logistical requirements on Bechtel and its associates: 3.7 million cubic yards of rock to excavate, 45 million pounds of pipe and structural steel to erect, 4.4 million cubic yards of concrete to pour. Remarkably, the entire project was completed under budget and two years ahead of schedule. Although Bechtel has since built bigger dams, none will ever be quite as important, to either the company or the country. It was Bechtel’s first megaproject and it shaped the company’s ambitions forever."

"Directions: From Kingman, travel I-40 eastbound to Hwy 93, Beale Rd. exit #48. Turn northwest on Hwy 93, continue 80 miles to the dam."

More info , click on the link under source....Hoover powerplant

Hoover Powerplant generators are primarily used for providing a low-cost peaking resource. Although some end user retail customers receive their entire requirement from Hoover, the 15 wholesale power customers blend their entitlement from Hoover power with other resources. Consequently, Hoover is not a sole source supplier. Contractual arrangements with the power customers provide for Hoover power to be used for "Ramping, Regulating, and Reserves."
The demand for Hoover power generation is seasonal, with the winter months as the low-demand period. This permits removing one penstock per year for preventative maintenance. Because four generators are normally supplied from each penstock, when the penstock is out of service, so are four generators. These generators may undergo routine maintenance during this outage but may not be, and therefore are not truly unavailable just lacking in a water supply.

Hoover generation is a direct function of river flow and downstream water demands. Power production is secondary to flood control, river regulation, storage, and orderly release of water to downstream requirements.

There has been a major shift in personnel at Hoover, Davis, and Parker Powerplants. Operational criteria moved from operating the powerplant generators as separate units and projects to an integrated operation of all units as though from one powerplant. This provided operating efficiencies and improved resource availability and stability to the power customers. Also, remote operation of Davis and Parker through a Supervisory Control System allowed for one shift per 5-day workweek at Davis and Parker Powerplants.

Unit availability and outage data is skewed due to the uprating program and the high costs associated with the "testing and debugging" of new equipment, including "infant mortality" associated with new equipment. Additionally, Hoover personnel were usually supporting construction contractors' personnel, who were requiring units to be taken out or put into service on an erratic basis while installing, testing, and debugging new equipment.


Hoover Powerplant is located in the Black Canyon of the Colorado River about 36 miles from Las Vegas, Nevada, on the Arizona-Nevada State line.

The project was authorized by the Boulder Canyon Project Act of December 21, 1928 (45 Stat. 1057), subject to the terms of the Colorado River Compact. The Boulder Canyon Project Adjustment Act (54 Stat. 774), dated July 19, 1940, provided for certain changes to the original plan. The Hoover Powerplant Act of 1984 (98 Stat. 1333) provided for the uprating of the generators and the construction of new visitor facilities.
Project Purposes: Hoover Dam and powerplant was constructed for the purposes of controlling the floods of the Colorado River, improving navigation and regulating the flow of the Colorado River, provide for storage and for the delivery of the stored waters thereof for reclamation of public lands and other beneficial uses exclusively within the United States, and for the generation of electrical energy as a means of making the project authorized a self-supporting and financially solvent undertaking. Floodwaters of the Colorado River are impounded by Hoover Dam and released when needed for irrigation and power generation. Irrigation water stored in the reservoir is used in the All-American Canal System; the Gila, Yuma, Yuma Auxiliary, and Palo Verde Projects; and the Colorado River Indian Reservation. A dependable supply of municipal, industrial, and irrigation water can be provided to the semiarid southern California coastal region. This supply is released from Lake Mead, diverted at Lake Havasu, and transported through the Metropolitan Water District's Colorado River Aqueduct to the area of use.

Hoover Dam is a concrete thick-arch structure, 726.4 feet high and 1,244 feet long at the crest. The dam and appurtenant structures required 4.4 million cubic yards of concrete. Hoover Dam and Powerplant was the first major concrete thick-arch dam constructed by Reclamation. Water for generation is conveyed through four penstocks from four intake structures immediately upstream and contiguous to the dam. Spillway structures use 16 foot by 100 foot drum gates which provide for an additional 16 vertical feet of storage capacity in Lake Mead, the reservoir impounded upstream of the dam.
