Since a capability crowd cheered on the opening on Nov 20 of the 2022 FIFA World Cup on the brilliantly lighted Al Bayt Stadium in Doha, the capital of Qatar, a steady provide of fresh energy from a photovoltaic energy station constructed by a Chinese language firm has been contributing to the worldwide sporting occasion, offering a significant inexperienced legacy.
The 800-megawatt Al Kharsaah photovoltaic energy station, Qatar’s first nonfossil-fuel energy station, was independently constructed by Energy-China Guizhou Engineering Co.
The station was put into operation in mid-October, considerably rising the share of renewables within the soccer occasion’s vitality consumption combine and serving to Qatar’s dedication to host a carbon-neutral World Cup, in response to the corporate.
“The carbon financial savings from the mission will likely be used to offset about half of the emissions generated through the World Cup,” mentioned Wei Yujin, vice-manager of the mission. “It’s anticipated to supply about 1.8 billion kilowatt-hours of fresh electrical energy to Qatar yearly, which may meet the ability demand from 300,000 households in Qatar.”
With an funding of $417 million, the station was constructed on 10 sq. kilometers of land within the Gobi Desert’s Al Kharsaah area, 50 kilometers from central Doha.
With 2 million photovoltaic cells, additionally it is one of many largest photovoltaic energy stations within the Center East and the third-largest single photovoltaic energy mission on the earth.
Building of the mission started in July 2020, and employees had to deal with a collection of difficulties, reminiscent of extraordinarily sizzling climate, sturdy wind and a labor scarcity as a result of COVID-19 pandemic.
“The station has the world’s largest energetic monitoring system and double-sided parts, to trace the solar’s location in actual time and preserve the photo voltaic panels and daylight at the perfect angle, whereas the double-sided parts enable the panels to appreciate photovoltaic conversion on each side,” mentioned Wei.
Wei highlighted the excessive diploma of the mission’s precision, mentioning that every 3000-meter-long set of parts has a variety of error of lower than 2 millimeters.
“In contrast with the normal mounted assist, the monitoring system has rather more put in elements, excessive set up accuracy necessities, and very strict debugging necessities for the management system,” he mentioned. “Due to this fact, we wanted thrice the same old set up interval and labor funding.”
To fulfill the mission schedule, the corporate organized a powerful crew to mobilize expert employees and administration expertise with photovoltaic building expertise from throughout the Center East. Then they supplied employees with video tutorials on set up and constructed a simulation platform for on-site instructing and practising.
“One other issue was brought on by the six-month-long extraordinarily sizzling climate interval,” mentioned Wei. “In keeping with native labor legislation, open work shouldn’t be allowed from 10 am to three pm throughout this era. Consequently, our on-site work needed to be organized at night time, bringing nice challenges to nighttime security administration.”
The corporate additionally strove to reduce the influence on the native surroundings and set up an vitality and useful resource conservation and recycling mechanism throughout building, reminiscent of making an in depth relocation plan for on-site native vegetation and animals.
In June, the primary stage of the mission was put into operation.
“The mission crew overcame numerous difficulties throughout two years of building,” mentioned Guo Wei, president of PowerChina Guizhou Engineering Co. “We used environmentally pleasant strategies and at last accomplished the mission safely and effectively with top quality.”
Lately, the corporate has supplied vitality and infrastructure building to international locations alongside the Belt and Highway routes. It has had contracts for 18 abroad tasks around the globe, together with 9 photovoltaic and wind energy tasks, with an put in capability of 1,800 megawatts.
