SunZia Wind And Transmission
SunZia Wind is a 3.5-gigawatt wind farm being developed in New Mexico, United States, in Lincoln County, San Miguel County and Torrance County. When completed, this will be the largest wind project in the western hemisphere. The wind project is paired with SunZia Transmission, a to carry the power to Arizona and California. SunZia Wind and Transmission are owned by the privately held American company Pattern Energy. The project reached $11B of funding in late 2023. Construction started in 2023 and operation is projected to start in 2026. Wind farm The project includes at least 900 wind turbines in Estancia Valley. In 2023, Pattern Energy ordered 674 General Electric 3.6 MW turbines (2.4 GW) and 242 Vestas V163-4.5 MW turbines (1.1 GW) while foundations were being dug. Transmission line The planned transmission would connect the SunZia wind farm in central New Mexico to Pinal county in south-central Arizona. It would consist of two 525 kV high-voltage direct current ( ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

San Pedro River (Arizona)
The San Pedro River is a northward-flowing stream originating about south of the international border south of Sierra Vista, Arizona, in Cananea Municipality, Sonora, Mexico. The river starts at the confluence of other streams (Las Nutrias and El Sauz) just east of Sauceda, Cananea. Within Arizona, the river flows north through Cochise County, Arizona, Cochise County, Pima County, Arizona, Pima County, Graham County, Arizona, Graham County, and Pinal County, Arizona, Pinal County to its confluence with the Gila River, at Winkelman, Arizona. It is the last major, undammed desert river in the Southwestern United States, American Southwest, and it is of major ecological importance as it hosts two-thirds of the avian diversity in the United States, including 100 species of breeding birds and almost 300 species of migrating birds. History The first people to enter the San Pedro Valley were the Clovis people who hunted mammoth here from 10,000 years ago. The San Pedro Valley has the ...

HVDC Transmission Lines
A high-voltage direct current (HVDC) electric power transmission system (also called a power superhighway or an electrical superhighway) uses direct current (DC) for electric power transmission, in contrast with the more common alternating current (AC) transmission systems. Most HVDC links use voltages between 100 kV and 800 kV. However, a 1,100 kV link in China was completed in 2019 over a distance of with a power capacity of 12 GW. With this dimension, intercontinental connections become possible which could help to deal with the fluctuations of wind power and photovoltaics. HVDC allows power transmission between AC transmission systems that are not synchronized. Since the power flow through an HVDC link can be controlled independently of the phase angle between source and load, it can stabilize a network against disturbances due to rapid changes in power. HVDC also allows the transfer of power between grid systems running at different frequencies, such as ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wind Farms In New Mexico
Wind is the natural movement of air or other gases relative to a planet's surface. Winds occur on a range of scales, from thunderstorm flows lasting tens of minutes, to local breezes generated by heating of land surfaces and lasting a few hours, to global winds resulting from the difference in absorption of solar energy between the climate zones on Earth. The two main causes of large-scale atmospheric circulation are the differential heating between the equator and the poles, and the rotation of the planet ( Coriolis effect). Within the tropics and subtropics, thermal low circulations over terrain and high plateaus can drive monsoon circulations. In coastal areas the sea breeze/land breeze cycle can define local winds; in areas that have variable terrain, mountain and valley breezes can prevail. Winds are commonly classified by their spatial scale, their speed and direction, the forces that cause them, the regions in which they occur, and their effect. Winds have ...

Point-to-point Construction
Point-to-point construction is a non-automated method of construction of electronics circuits widely used before the use of printed circuit boards (PCBs) and automated assembly gradually became widespread following their introduction in the 1950s. Circuits using thermionic valves (vacuum tubes) were relatively large, relatively simple (the number of large, hot, expensive devices which needed replacing was minimised), and used large sockets, all of which made the PCB less obviously advantageous than with later complex semiconductor circuits. Point-to-point construction is still widespread in power electronics where components are bulky and serviceability is a consideration, and to construct prototype equipment with few or heavy electronic components. A common practice, especially in older point-to-point construction, is to use the leads of components such as resistors and capacitors to bridge as much of the distance between connections as possible, reducing the need to add addit ...

San Carlos Apache Tribe
The San Carlos Apache Indian Reservation (Western Apache: Tsékʼáádn), in southeastern Arizona, United States, was established in 1872 as a reservation for the Chiricahua Apache tribe as well as surrounding Yavapai and Apache bands removed from their original homelands under a strategy devised by General George Crook of setting the various Apache tribes against one another. Once nicknamed "Hell's Forty Acres" during the late 19th century due to poor health and environmental conditions, today's San Carlos Apaches successfully operate a Chamber of Commerce, the Apache Gold and Apache Sky Casinos, a Language Preservation program, a Culture Center, and a Tribal College. History On December 14, 1872, President U.S. Grant established the San Carlos Apache Reservation. The government gave various religious groups responsibility for managing the new reservations, and the Dutch Reformed Church was in charge of the San Carlos Apache Indian Reservation. The church chose John Clum, who tu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bureau Of Land Management
The Bureau of Land Management (BLM) is an agency within the United States Department of the Interior responsible for administering federal lands. Headquartered in Washington DC, and with oversight over , it governs one eighth of the country's landmass. President Harry S. Truman created the BLM in 1946 by combining two existing agencies: the General Land Office and the Grazing Service. The agency manages the federal government's nearly of subsurface mineral estate located beneath federal, state and private lands severed from their surface rights by the Homestead Act of 1862. Most BLM public lands are located in these 12 western states: Alaska, Arizona, California, Colorado, Idaho, Montana, Nevada, New Mexico, Oregon, Utah, Washington and Wyoming. The mission of the BLM is "to sustain the health, diversity, and productivity of the public lands for the use and enjoyment of present and future generations." Originally BLM holdings were described as "land nobody wanted" because home ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Power Purchase Agreement
A power purchase agreement (PPA), or electricity power agreement, is a contract between two parties, one which generates electricity (the seller) and one which is looking to purchase electricity (the buyer). The PPA defines all of the commercial terms for the sale of electricity between the two parties, including when the project will begin commercial operation, schedule for delivery of electricity, penalties for under delivery, payment terms, and termination. A PPA is the principal agreement that defines the revenue and credit quality of a generating project and is thus a key instrument of project finance. There are many forms of PPA in use today and they vary according to the needs of buyer, seller, and financing counter parties. Contractual terms of a PPA may last anywhere between 5 and 20 years, during which time the power purchaser buys energy, and sometimes also capacity and/or ancillary services, from the electricity generator. Such agreements play a key role in the financin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
