Massive Arizona Solar Project: Tesla to Buy 90% of New Power Plant's Output
ContourGlobal has begun construction of a 509-megawatt solar power plant in Arizona, USA. The project includes more than 760,000 solar panels and a 1.4 GWh battery storage system, and is set to supply about 90% of its generated electricity to Tesla under a long-term agreement.
According to Ambassador Arjan, the expansion of renewable energies in America and Arad has become a new stage, and the combination of solar power plants with battery storage systems provides the possibility of providing clean electricity in more hours of the day and night. In this regard, the large Sterling solar project in the state of Arizona is being developed in partnership with Contour Global and Tesla's cooperation in purchasing electricity. In addition to increasing the production capacity of clean energy, this plan can play an important role in providing electricity needed by Tesla and strengthening the infrastructure of the region's electricity network.
The construction of a 509 megawatt solar power plant in Arizona has begun
ContourGlobal Energy recently announced the start of construction on the Sterling Solar Project with a groundbreaking ceremony on October 6. This project is located in Mojave County, about 20 miles north of Lake Havasu, Arizona, and covers an area of more than 2,000 hectares.
The capacity of this solar power plant reaches 509 megawatts of direct current (DC), which is equivalent to about 450 megawatts of alternating current (AC). According to the plans, this complex will be put into operation in 2028 and after completion, it will become the largest renewable energy asset of Contour Global in the world.
Estimates show that the Stirling power plant will produce more than 1.1 terawatt hours of electricity annually; A volume that can supply the electricity needed by a city with a population of approximately 100,000 to 120,000 people for one year.
More than 760 thousand solar panels and huge battery storage system
One of the important features of the Stirling project is the combination of high capacity solar power generation with a large-scale energy storage system. This complex is supposed to house more than 760,000 solar modules and more than 300 battery storage compartments.
The storage system of this project is designed to provide 360 megawatts of power, and its storage capacity reaches about 1.4 gigawatt hours. The batteries used are Lithium Iron Phosphate (LFP) type and use liquid cooling system and integrated fire protection technology.
According to the announced information, these batteries can store and supply about four hours of generated electricity when operating at rated power. The combination of the solar power plant and the storage system also provides the possibility of providing clean electricity up to 16 hours a day; A feature that can help reduce fluctuations in solar energy production and increase the reliability of electricity supply.
Tesla's long-term contract to buy 90% of the produced electricity
One of the most important parts of this project is the long-term power purchase agreement between Contour Global and Tesla. According to this contract, which is organized in the form of a corporate power purchase agreement (PPA), Tesla is supposed to receive more than one terawatt hour of clean electricity from the Sterling plant annually.
According to the reports published by the energy media, this contract covers about 90% of the expected electricity production of the power plant. Such an agreement would ensure Tesla's long-term supply of renewable energy while also providing a major and specific buyer for Sterling's project.
The combination of solar power generation and battery storage is particularly important in this plan; Because the storage of energy produced in sunny hours can increase the possibility of electricity supply in other hours. This feature is very important for large industrial consumers who need a stable supply of electricity.
Antonio Camisequerra, president and CEO of Contour Global, has announced in a statement about this project that the design of the complex was done according to the specific needs of the customer to provide the possibility of providing clean and reliable electricity up to 16 hours a day.
Connection to the regional power grid and access to the California market
In addition to supplying Tesla with electricity, the Sterling project is also important in terms of energy transmission infrastructure. According to published reports, this power plant will be connected to the electricity transmission network of the US Western Regional Power Authority and has received the necessary permits to transmit electricity to the California Independent System Operator (CAISO) electricity market.
This access can provide the possibility of supplying the produced electricity of the project to the regional market and help to use the renewable energy production capacity more effectively. The development of such projects is important in a situation where the increase in the share of solar energy in the power grid increases the need for suitable transmission and storage infrastructures.
By implementing this plan, Contour Global expands its assets portfolio in America. According to the report of PV Magazine USA, the total capacity of the company's thermal, renewable and storage assets in the United States, including projects in operation and construction, will reach about 2.4 gigawatts.
Creating hundreds of job opportunities and developing local infrastructure
In addition to energy and environmental impacts, the construction of the Stirling plant will also have local economic consequences. The implementation of the project is expected to create an average of 400 construction jobs in the region.
During the construction of this complex, a new access road of approximately 5.2 miles will be constructed. The route, called Polaris Road, connects the project site to the historic section of US Route 66 between Tupac and Kingman.
The financing of the project is done privately, and according to the published information, to cover the costs of the construction period, the equity bridge facility has also been considered by a group of international banks.
Arizona's position in the development of American solar energy
In recent years, the state of Arizona has become one of the most important regions for the development of solar energy in the United States. According to the statistics presented in the reports of the energy industry, the installed solar capacity of this state has reached about 13 thousand 198 megawatts and solar energy provides about 18.23% of its electricity.
According to these statistics, solar power generation in Arizona is enough to power nearly two million homes. By adding 509 megawatts of direct current solar capacity and a 1.4 gigawatt-hour storage system, the Sterling project will increase the generation capacity and flexibility of the state's power grid.
The cooperation between Contour Global and Tesla also shows that long-term power purchase contracts have become one of the important tools for financing and developing clean energy projects. In such models, the presence of a large buyer can help reduce the risk of electricity sales and make project income more predictable.
The Sterling Solar Project in Arizona is an example of the energy industry's move toward combining renewable power generation with large-scale storage. This power plant with a capacity of 509 megawatts, more than 760,000 solar panels and a 360 megawatt battery system with a storage capacity of about 1.4 gigawatt hours is supposed to produce more than 1.1 terawatt hours of electricity annually.
A long-term agreement with Tesla to purchase about 90 percent of the electricity generated, along with a 2028 commissioning schedule, makes the project one of the most significant solar energy and storage projects in the United States. If the plans are implemented on schedule, Sterling could both help deliver clean electricity to large consumers and strengthen ContourGlobal's position in the renewable energy market.
