Several countries, trying to meet climate goals, made renewable energy their ongoing trend.

The Global Wind Energy Council (GWEC) released the 2021 Global Wind Energy Report in March. This report shows that the global wind industry set a new record in 2020: 93 GW (Gigawatts) of new installations worldwide, an increase of 53% over the previous year.

Today, there are 743 GW of wind power capacity worldwide, helping to avoid more than 1.1 billion tons of CO2.

China and the United States are the two largest wind energy markets in the world. In 2020, they achieved record growth in wind installations, accounting for 75% of new insertions.

The other nations are also not far behind; India possesses the second-largest wind farm in the world.

Here is the index of the top ten largest wind farms in the world:

Table of Contents

1. The Gansu wind farm

The Chinese government built the Gansu wind farm in Gansu province to improve its clean energy sector. At a current capacity of 8 GW, it is the largest onshore wind farm globally and is expected to grow to 20 GW capacity by 2020.

However, the Chinese government halted the construction; therefore, they will install the expected 20 GW capacity by 2022.

The project site is located on the Gobi Desert, southwest of Yumen Town, Jiuquan City, Gansu Province. So it is also known as Wind Energy in Jiuquan.

The first phase of construction began in 2009 with an estimated cost of $ 17.5 billion. It reached 3,800 megawatts and consisted of 18 parks of 200 megawatts and another 2 of 100 megawatts.

Currently, 60 parks of 12,000 megawatts are in operation. For the coordination of all the parks, a control system has been developed.

This system manages and maximizes the energy efficiency and stability of the electricity generated in the turbines, entry into the supply network, and subsequent distribution.

The average yearly wind speed of the wind farm at the height of 70 meters is 7.89 m/s, and the average annual wind power density is 427.5 W/m2. Once the project’s construction is completed, it will save 250,000 tons of standard coal each year.

It will reduce sulfur dioxide emissions by 8,071 tons, nitrogen dioxide emissions by 2,290 tons, carbon dioxide emissions by 427,000 tons, carbon monoxide emissions by 58 tons, and smoke and dust emissions by 454,000 tons.

Despite the large amount of electricity it produces, the wind farm is not being adequately utilized. China’s low demand for wind energy and the wind farm’s location away from major cities contributed to the underutilization of wind energy.

3. Alta Wind Energy Center

This wind farm spans 3,200 acres in the foothills of the Tehachapi Mountains in Kern County, California. It is also known as the Mojave Wind Farm.

It has a current capacity of 1547 MW, making it the third-largest wind farm in the world. It is also the largest onshore wind energy project in the United States.

Terra-Gen Power first owned and developed Mojave Wind Farm, but operations control has been distributed to several companies. Such as NRG Renew, BHE Renewables, EverPower, and Brookfield Renewable Energy Partners.

In 2006, Alta Wind Energy Center signed a 25-year extended agreement with Southern California Edison (SCE) for energy trade.

The creation of the center started in July of 2010 and was completed in April 2011. It embodied 1 to 5 units at the end of the first phase.

The second phase started in early 2011 and was completed in December 2011. It consisted of units 6 to 9. The construction of units 7 to 9 began in April 2012 and was completed in December 2012. The project was completed in 2014 and had 600 turbines in total.

The biggest obstacle to the success of the project was insufficient power transmission capacity. Therefore, the South California Edison local government built a transmission system, the Tehachapi Renewable Transmission Project. It overcame the obstacle of long-distance transmission and fully exploited the potential of the wind farm.
