Baihetan Hydropower Station， the worlds largestand most difficult?to?build hydropower project that isstill under construction， generated 10 billion kilowatt?hours of green power in 2022.

The power amount equals that produced byburning about 3.06 million metric tons of standardcoal， and represents a reduction of about 8.38 million tons of carbon dioxide， which adds agreat deal to Chinas green transformation in economic and social development and its goalof peaking carbon dioxide emissions by 2030 and reaching carbon neutrality（碳中和）by2060. Since the first generator units went into operation， the station has in all generatedbillions of kWh of power， and all units are stably running. At present， the last two generatorunits of the station are in their closing stage of final assembly （安裝）.

Located over the Jinsha River on the border of Southwest Chinas Yunnan and Si?chuan provinces， Baihetan Hydropower Station is a national major project for the countryswest?to?east power transmission， which aims to transmit electricity from the resource?rich?western part of China to energy?hungry regions in eastern China.

The station is installed with 16 hydro?generating units， each with a capacity of 1 mil?lion kilowatts， the largest single?unit capacity in the world. It is the most technically diffi?cult hydropower project under construction in the world today， dubbed the Mount Qomol?angma of the hydropower industry. The efficiency of the turbine （渦輪機(jī)） for power genera?tors is 96.7 percent， ranking at the worlds leading level.

Baihetan Hydropower Station， together with the Wudongde， Xiluodu， Xiangjiaba，Three Gorges， and Gezhouba power stations， forms the worlds largest clean power corridor.All of them are operated by China Three Gorges Corporation.

After reaching full operation， Baihetan Hydropower Station will be the worlds second?largest of its kind after Chinas Three Gorges Dam. The station can generate 62.4 billion kWhof clean electricity every year， cutting the usage of 19.68 million tons of standard coal andreducing emissions equivalent to 51.6 million tons of carbon dioxide. The station will alsobe able to power electricity consumption for 75 million people.

Ⅰ. Difficult sentence in the text

The power amount equals that produced by burning about 3.06 million metric tons ofstandard coal， and represents a reduction of about 8.38 million tons of carbon dioxide，which adds a great deal to Chinas green transformation in economic and social develop?ment and its goal of peaking carbon dioxide emissions by 2030 and reaching carbon neu?trality by 2060. 這個發(fā)電量相當(dāng)于燃燒約306萬噸標(biāo)準(zhǔn)煤產(chǎn)生的電量，并減少了約838萬噸的二氧化碳，為我國經(jīng)濟(jì)社會發(fā)展的綠色轉(zhuǎn)型和2030年前實現(xiàn)碳達(dá)峰、2060年前實現(xiàn)碳中和的目標(biāo)提供了有力保障。

【點石成金】本句是一個復(fù)合句。that為代詞；produced... standard coal為分詞短語作代詞that的后置定語；第一個and連接并列謂語equals和represents；which引導(dǎo)非限制性定語從句；第三個連詞and連接前面介詞to的賓語Chinas green transformationin economic and social development 和its goal of peaking carbon dioxide emissions by2030 and reaching carbon neutrality by 2060；最后一個and連接goal后面介詞of的兩個賓語。

Ⅱ. Text?centered chunks

under construction 在建設(shè)中

go into operation 投入運營

aim to do sth 力爭做到某事
