在不少人眼中，沙漠過于荒涼。

但于李巖而言，他每日身處的工作地——寧夏回族自治區(qū)中衛(wèi)市騰格里沙漠東緣的光伏產(chǎn)業(yè)園，卻“猶如仙境一樣”。

一排排光伏板亮閃閃、齊整整地布陣在金色沙漠之中，一眼望不到邊，規(guī)模之巨令人震憾。

荒漠里生機(jī)無限

中衛(wèi)市沙漠光伏產(chǎn)業(yè)園到中衛(wèi)市的直線距離約15 公里。今年37 歲的李巖，是國家電投北京公司寧夏京銀智慧新能源有限公司中衛(wèi)恒基偉業(yè)光伏電站的一名值長，兩年前他從一家工業(yè)企業(yè)跳槽到光伏電站。

比起嘈雜的企業(yè)車間、喧囂的都市，沙漠的靜謐是李巖最先感受到的良好“反差”。

除了安靜的環(huán)境，李巖作為參與者，更見證了腳下這片荒漠日漸生機(jī)勃勃的過程。越來越好的生態(tài)環(huán)境帶給他的除了欣喜，還有一份自豪。

“剛來的時候，這兒基本見不到草。”李巖帶著記者走進(jìn)光伏電站站區(qū)，他想找一塊“不毛之地”，以證明自己所言非虛。走了好半天，“勉強(qiáng)”找了一小塊沙地，“嗨，現(xiàn)在不長草的地方還不好找了?！崩顜r說。

﹃連片的光伏板組件也算立了一份功。”恒基偉業(yè)光伏電站站長梁利明忍不住為光伏板“請功”。

此前，電站充分參考和借鑒中衛(wèi)麥草方格的方式進(jìn)行固沙，即把一束束麥草呈1 米見方的方格狀鋪在沙地上，用鐵鍬把干草深扎到沙地中，留麥草的1/3 或一半自然豎立在四邊，然后再將方格中心的沙子撥向四周麥草根部，使麥草牢牢地豎立在沙地上。麥草方格相對地阻擋了沙子流動，同時將空氣中的水分子和降水截留在沙層表面，一定程度上為淺根性植物的生長提供了水分供應(yīng)。

“再在干草中央及周圍撒上草籽，等待雨水，伺機(jī)生長。”梁利明介紹，在植物生長的過程中，連成片的光伏板組件發(fā)揮了重要的庇佑和助力作用。

“我們電站的光伏板組件都是固定夾角，基本呈32°～37°角。光伏組件板遮蔽場區(qū)大部分地面，能有效阻擋陽光直射，使水分蒸發(fā)量減少20%～30%，起到保墑作用?！奔由锨逑措姵匕宓乃?、露水及降雨，都促進(jìn)了花棒、檸條、駱駝刺等植物的生長。

“它們的生長大大降低了近地面層的風(fēng)速，更好地固定了流沙，并阻止沙丘前移。”“發(fā)電人”梁利明成了半個“治沙人”。

作為“回報”，生長起來的植物也使光伏板組件免受風(fēng)沙“刨根之苦”——“光伏設(shè)備的螺旋樁扎在1.5米深的沙地里，若是沙子不固定，螺旋樁裸露于地面多了，根基就不穩(wěn)了?！币虼耍膊槁菪龢妒欠穹€(wěn)固也是日常巡檢工作內(nèi)容之一。而日漸壯大的植物正是鎖住“沙龍”、保護(hù)螺旋樁的關(guān)鍵。此外，沙塵對發(fā)電量也有影響，植被的生長降低了沙塵揚(yáng)起的幾率。

作為央企，改善生態(tài)、保護(hù)環(huán)境是義不容辭的社會責(zé)任。同時，中衛(wèi)市委市政府發(fā)起的植綠增綠“大會戰(zhàn)”，也給屬地企業(yè)、園區(qū)等各機(jī)構(gòu)布置有“綠化作業(yè)”。

“按照各方面的生態(tài)建設(shè)要求，近幾年，公司持續(xù)加大植綠增綠投入。去年，我們在生產(chǎn)區(qū)、生活區(qū)、進(jìn)場道路等場站內(nèi)外，共栽植紅柳等耐旱樹種4000 多棵?！?梁利明介紹。

電站生活區(qū)位于場站東北邊，沿路不時有鳥兒飛過，嘰嘰喳喳的鳥叫聲清脆悅耳?！傍B可多了，雖然都叫不上名字?！崩顜r早已見慣了這些不知名的“朋友們”。

“還有很多野雞、野兔，我還見了兩次狐貍呢。”梁利明說，每晚回宿舍的路上，都能與園區(qū)里的這些“?？汀毕嘤?。

通過各項生態(tài)改善措施，場區(qū)已逐步構(gòu)建起一個穩(wěn)固的綠色防護(hù)體系，并產(chǎn)生“沙漠化逆轉(zhuǎn)現(xiàn)象”，在一定程度上形成了良性循環(huán)發(fā)展。

“草長起來了，天上飛的、地上跑的小動物自然就來了?！绷豪髡f，小時候在山西農(nóng)村長大，多年不見這類小動物了，如今見到十分親切。

守好生態(tài)線，延長發(fā)展線

沙漠地區(qū)降水量稀少，每年有300 多天都是烈日當(dāng)頭。而今，這些“劣勢”正在轉(zhuǎn)為優(yōu)勢。

根據(jù)相關(guān)研究，每平方米的沙漠每年接收的太陽能約為2000 至3000 千瓦時。如果能把這些太陽能全部轉(zhuǎn)化為電能，足以讓1 千瓦的電器使用3000 小時。按照中國家庭年均用電量6 千瓦計算，只要2 平方米沙漠就能滿足一個家庭一年的用電量。

國家電投北京公司以“敢叫沙漠換新顏”的氣魄，積極推動“三北”地區(qū)綠色發(fā)展和生態(tài)文明建設(shè)，在內(nèi)蒙古建成120 兆瓦沙漠光伏項目，并謀劃了千萬千瓦級的寧夏騰格里沙漠光伏項目，為中國西北區(qū)域治沙固沙、生態(tài)保護(hù)、經(jīng)濟(jì)發(fā)展探索出一條“治黃治沙”的新道路。

“中衛(wèi)的光照資源充足，可研利用年均日照時間為1500 小時，是國家1 類太陽能資源地區(qū)。此外，空氣質(zhì)量好，沒有污染，光伏板使用壽命相應(yīng)也能更長一些?！绷豪鹘榻B，光伏板一般一年需要清潔4 次，但在這里一年清潔1 次就夠了。

同處中中衛(wèi)市沙漠光伏產(chǎn)業(yè)園的寧夏慶陽新能源有限公司，也享受著與恒基偉業(yè)光伏電站同樣的各種“利好”。

慶陽光伏電站同樣高度重視生態(tài)保護(hù)及改善，在電站外圍20 米以內(nèi)開展植綠增綠工作，走出了具有特色的光伏發(fā)電場區(qū)同風(fēng)沙防護(hù)區(qū)造林種草相結(jié)合的綠化路子。

“環(huán)境好了，大家工作起來心情也能美美的?！睉c陽光伏電站駐站代表邢猛說。

據(jù)介紹，慶陽光伏電站占地3180畝，項目生產(chǎn)區(qū)有96 個光伏方陣，裝機(jī)容量為100 萬兆瓦?！斑@個項目與其他傳統(tǒng)火力發(fā)電方式相比，年均上網(wǎng)電量15099 萬千瓦時。按照火電煤耗平均350 克標(biāo)煤/千瓦時，每年可節(jié)約標(biāo)準(zhǔn)煤5.28 萬噸，減少了二氧化碳排放量約15 萬噸?！毙厦徒o出了慶陽光伏電站的減碳“賬單”。

中衛(wèi)市發(fā)改委則有一份“大賬單”。

2009 年以來，中衛(wèi)市探索在沙漠地區(qū)發(fā)展沙漠光伏產(chǎn)業(yè)。目前已形成了占地6.5 萬畝、裝機(jī)容量為1030 兆瓦規(guī)模的光伏產(chǎn)業(yè)園，實現(xiàn)了沙漠生態(tài)效益、經(jīng)濟(jì)效益和社會效益的有機(jī)融合。

騰格里沙漠的光伏板形成了一片藍(lán)色的“海洋”Blue “ocean” comprised of PV panels in the Tengger Desert

Deserts are just land that has very little water and very few plants growing on it for most people.

However, the Photovoltaic Industrial Park on the east side of the Tengger Desert, Zhongwei City, Ningxia Hui Autonomous Region, where Li Yan works is a ”fairyland” in his mind.

Rows of shining photovoltaic panels line up in an orderly manner in the golden desert. It seems that there is no boundary for the panels as they are stretching out in the desert, forming an impressive scene.

Possibilities in deserts

There is a straight-line distance of 15km from the Zhongwei Desert Photovoltaic Industrial Park to the urban area of Zhongwei City. Li Yan, a 37-year-old head of Zhongwei Hengji Weiye Photovoltaic Power Station,Ningxia Jingyin Intelligence New Energy Co., Ltd. of SPIC Beijing Electric Power Co., Ltd. hopped to this position two years ago from an industrial enterprise.

Compared to the noisy workshops and bustling city, the quietness in the desert was the first difference he got to feel and enjoy.

In addition to the tranquil environment, he, as a participant,witnessed the great changes in this dry land that help it become dynamic. When the ecological environment becomes better and better, he felt happy and was proud of his work.

“There was few grass when I first came here,” said Li Yan.Li guided reporters in the industrial park, trying to find a piece of land not covered by plants to prove his words. In fact, it was hard to find such land without plants. “Well, it is not that easy to find a land that no plants are growing on nowadays,” said Li.

“Row upon row of photovoltaic panel modules help change the environment,” Liang Liming, head of the photovoltaic power station could not wait to tell reporters about the importance of the panels.

Previously, the photovoltaic power station adopted the straw checkerboards to control windblown sand. The method is to install 1×1m straw grids deeply into the ground by spades and leave just one third or half of the straw out of the ground and move sand to cover the root of the straw, thus ensuring straw grids can be fixed on the ground. Straw checkerboards are helpful to fix the sand and retain water molecules in the air and rainfalls to the surface, which can provide water for shallow-rooted plants to grow.

“Then we will spread grass seeds in the center and wait for the rainfalls to help them grow naturally,” Liang said. When the seeds are growing, rows of panel modules serve as sand barriers for them.

“The included angle between panel modules and the ground is about 32° to 37°. The shadow formed by the panel modules can cover most area of the industrial park, which can effectively avoid direct sunlight and reduce 20% to 30% of water evaporation of the covered areas so as to preserve the soil moisture.” The water used to clean the panels, dew and rainfalls will foster the growth of some plants, such as Hedysarum scoparium, Caragana korshinskii and Alhagi sparsifolia.

“These plants can slow down the wind speed near the surface to further control flowing sand and stop dunes from expanding,” Liang Liming, head of the power station and also an amateur sand fixation fighter told reporters.

As a positive result, these plants protect photovoltaic panel modules from being blown down and eroded by the wind and sand. “Our panel modules are rooted 1.5m deep in the land with their screw piles. They will be exposed to the ground if the sand is flowing around. Then, the modules cannot stand still.” Therefore, staff will patrol the park every day to check whether screw piles are fixed. The growing plants are essential for sand consolidation and protecting screw piles. In addition,they can also reduce sand and dust storms to improve the efficiency of power generation.

As China's centrally-administered state-owned enterprise(central SOE), improving the ecological environment and protecting our planet is the social responsibility we shall bear.Meanwhile, CPC Zhongwei Municipal Committee and the Municipal Government have launched a greening campaign and also encourage enterprises, industrial parks and other organizations to shoulder responsibility for making the land greener in the jurisdictions.

“To fulfill the requirements of the ecological development,we have invested more into the greening plan in recent years.Last year, we planted more than 4,000 drought-resistant trees,like rose willows in the manufacturing area, living area, roads towards the power station and some areas outside of the station,” said Liang.

The living area is situated northeast of the station. Birds are frequently heard twittering around. “There are many birds and I even don’t know their names,” Li Yan was familiar with these"friends" though he couldn’t figure out their names.

“Besides, I find many pheasants and hares. Sometimes, I even see foxes,” Liang told us. Every night on the way back to the dormitory, he would encounter these “neighbors” in the industrial park.

Based on various ecological improvement measures, the industrial park has established a stable environment protection system and achieved ecological restoration in some areas,forming a positive cycle of development to some extent.

“You see that grass grows tall and various animals come back,” said Liang. Liang Liming grew up in a village in Shanxi Province and he was happy to see these old friends he was familiar with in his childhood.

Protecting ecological environment is to promote sustainable development

It hardly rains in deserts and nearly 300 days in deserts are in extreme heat throughout the year. At present, the hot weather is no longer a disadvantage of deserts.

According to corresponding research, the solar energy received per square meter of deserts can reach 2,000 to 3,000kWh annually. Such an amount of energy can ensure a 1kW equipment to use 3,000 hours if the energy can be converted into electricity. The average annual household power consumption in China is about 6kW and only 2square meters of deserts can supply sufficient power for one family to use in a year.

With the ambition to make deserts greener, SPIC Beijing Electric Power Co., td. strives to promote greening and ecological conservation in Northeast China, the north part of North China and Northwest China in an active manner. The company has constructed a 120MW desert photovoltaic project in the Inner Mongolia Autonomous Region and planned 10 million kW desert photovoltaic bases such as Ningxia Tengger Desert Photovoltaic Project to explore a brand new way for sand control and fixation, environment protection and economic development in Northwest China.

"Zhongwei City has adequate light resources. The feasibility study shows that the average annual sunshine duration that can be applied is 1,500 hours, making it one of the national class 1 solar energy zone. Besides, the photovoltaic panels can work longer here because of the good air quality and less pollution in local areas," Liang explained to reporters. Normally, they need to clean photovoltaic panels four times a year but in Zhongwei, one time for a year will be fine.

Similar to the Hengji Weiye Photovoltaic Power Station in the Zhongwei Desert Photovoltaic Industrial Park,Ningxia Qingyang New Energy Co., Ltd. also benefits from environmental protection.

Qingyang Photovoltaic Power Station also attaches great importance to ecological protection and improvement. Plants were planted in the area 20m outside the station, reflecting the enterprise's unique measures in environmental protection,namely the integration of the power station development and afforestation for sand fixing.

“We work happily in a better natural environment,” said Xing Meng, representative of Qingyang Photovoltaic Power Station.

The Qingyang Photovoltaic Power Station covers an area of around 212 hectares. There are 96 photovoltaic panel arrays,with an installed capacity of 100MW in its manufacturing area.“Compared with other traditional thermal power generation methods, the average annual on-grid power of our project can achieve 150.99 million kWh. Normally, the coal consumption of thermal power generation is 350g standard coal/kWh.Thus, we can save 52，800 tons of standard coal and reduce carbon dioxide emissions by about 150，000 tons,” Xing Meng showed the achievements Qingyang Photovoltaic Power Station made in carbon reduction.

Zhongwei City has a big and long-term plan for carbon reduction.

It started exploring the possibilities of the desert photovoltaic industry in 2009. At present, a photovoltaic industrial park that covers an area of 4333.3 hectares and has an installed capacity of 1030MW is ready to integrate ecological benefits, economic benefits and social benefits into the city.

“The construction of the 6GW photovoltaic base at the southeast of the Tengger Desert has provided significant opportunities for the energy transformation and upgrading and highquality development of Zhongwei,”told Zhang Junhua, Director of Development and Reform Commission of Zhongwei. The city has planned to develop the desert photovoltaic industry in a concentrating and connecting area and the planning area is about 17333.3 hectares.

Zhongwei Desert Photovoltaic Industrial Park consists of photovoltaic manufacturing areas, photovoltaic power generation areas and sightseeing areas.It serves as a model of desert ecological system restoration and also focuses on ecological sightseeing in deserts.Based on sand control, sand fixation and utilization, the industrial park has boldly explored new and effective methods to maximize the ecological and economic benefits of the industry in deserts.

The actual installed capacity of the photovoltaic power generation areas is 1200MW. Up to now, 11 enterprises have settled in the industrial park and the station capacity of constructed stations has reached 1030MW.

“When the construction is completed,it will have a great impact on improving the regional ecological environment and promoting energy saving. 8.4 billion kWh on-grid power is expected to be generated and 7.5 million tons of carbon dioxide emissions can be reduced,” said Zhang.

On his visit to Ningxia Hui Autonomous Region, General Secretary Xi Jinping gave an important task and emphasized that Ningxia should “strive to build a leading area for ecological protection and highquality development of the Yellow River Basin.”

In recent years, Zhongwei has firmly fulfilled the requirements of the Ningxia Hui Autonomous Region Party Committee and the government to develop a national comprehensive demonstration area in high efficiency and earnestly followed the development strategy of enhancing a green energy, green industries and green development. The city strives to strengthen the quality development of the whole new energy industrial chain, accelerate the ecological protection of the Yellow River Basin, and build itself a leading city with high efficiency in development and a beautiful natural environment.

Zhongwei is ready to explore green energy in local areas and promote green hydrogen energy manufacturing and environmentally friendly development. Based on clean energy bases in the zigzag area of the Yellow River, the city will optimize its new energy industry layout, put its focus on building “two parks and two bases” and set a batch of “photovoltaic industry+ecology” vertically integrated demonstration projects, including a combination of agriculture and photovoltaic industry, forests, hills and photovoltaic industry and the rooftop photovoltaic system to build Ningxia a clean energy powerhouse.

“So far, the total installed capacity of new energy in the city has reached 8.22 million kWh, accounting for 83% of the total power generating capacity in the city and 29% of the total installed capacity of new energy in the Ningxia Hui Autonomous Region. The installed capacity of new energy ranks second in the Ningxia Hui Autonomous Region,including 4.4 million kWh photovoltaic power which accounts for 32% of the total installed capacity of it in Ningxia,” Zhang introduced to us.

Depending on the integrated development of industrial parks in Zhongwei City and Zhongning County, Zhongwei has initially formed an integrated photovoltaic industrial chain targeted to the development of industrial silicon,monocrystalline silicon and polycrystalline silicon, solar cell components and photovoltaic power stations. The development of the silicon industry is smooth, with monocrystalline silicon production capacity reaching 5GW.

“In 2022, Zhongwei will continue to foster its industrial restructuring and strive to exceed 10 million kWh in new energy installed capacity.”

In the near future, Zhongwei will advance the photovoltaic industry in the “two parks and two bases”. The city will ensure the quality and efficiency of the photovoltaic industrial park and improve the efficiency of both photovoltaic power generation and land utilization while carrying out the pilot project of building green power industrial parks.

“We aim to achieve 18 million kWh new energy installed capacity, over 25.2 billion kWh annual power generation and reduce at least 22 million tons of carbon dioxide emissions by 2025.”

At present, Zhongwei speeds up the implementation of the
