The world’s largest hybrid solar-hydro power plant started producing electricity in the eastern Tibetan Plateau on Sunday, according to Chinese state media reports.

With an installed capacity of 1 gigawatt of solar panels and 3GW of hydropower generators in the Yalong River plateau in Sichuan province, the plant can produce 2 billion kilowatt-hours of electricity annually, equivalent to the energy consumption of more than 700,000 households for a year, according to state media.

The plant is part of a huge renewable production base planned by the Chinese government to eventually generate clean energy for 100 million households – almost equal to the US population – for the length of the 1,500km-long river.

据中国官方媒体报道，世界上最大的混合太阳能水电发电厂于周日在青藏高原东部开始发电。

据官方媒体报道，该电站在四川省雅砻江高原的太阳能电池板装机容量为1千兆瓦，水力发电机装机容量为3千兆瓦，年发电量为20亿千瓦时，相当于70多万户家庭一年的用电量。

该工厂是中国政府计划的一个大型可再生能源生产基地的一部分，该基地最终将为1500公里长的长江流域的1亿户家庭(几乎相当于美国人口)提供清洁能源。

The Kela solar-hydro power plant is on a mountain in Yajiang county, Ganzi prefecture, Sichuan – 4,600 metres (15,000 feet) above sea level and 1,000 metres higher than Lhasa, the highest city in the world – making it the highest-altitude project of its type in the world.

The hybrid solar-hydro design leverages the consistent energy production of hydro power to offset the variability of solar power.

克拉太阳能水力发电厂位于四川省甘孜州雅江县的一座山上，海拔 4,600 米（15,000 英尺），比世界上海拔最高的城市拉萨高出 1,000 米，使其成为海拔最高的项目。

太阳能-水力混合设计利用水力发电的稳定发电来抵消太阳能发电的可变性。

The electricity generated by the solar power station is first transported through power lines to the Lianghekou Hydropower Station 50km (31 miles) away. Then the power generated by the solar and hydro stations are combined and fed into the grid.

This design helps balance fluctuations in solar power, which generates more electricity during the day and less at night and more on sunny days than on cloudy days.

It also allows the system to adapt power generation over a longer period, letting solar power generate more during dry seasons and greater hydro power output in rainy seasons.

太阳能发电站产生的电力首先通过电线输送至50公里（31英里）外的两河口水电站。然后，太阳能发电站和水力发电站产生的电力被合并并输入电网。

这种设计有助于平衡太阳能的波动，白天发电量较多，夜间发电量较少，晴天发电量多于阴天。

它还允许系统在更长的时间内适应发电，让太阳能在旱季发电更多，在雨季发电更大的水力发电。

his technology solves the safe connection of solar power with the grid and prevents wastage, addressing solar power’s inherent dependence on the weather.

“It serves as a good example for large-scale centralised development of clean energy in the world,” state news agency Xinhua reported.

该技术解决了太阳能发电与电网的安全连接并防止浪费，解决了太阳能发电对天气的固有依赖性。

官方通讯社新华社报道说：“它为世界大规模集中开发清洁能源树立了典范。”

The Kela plant is the first gigawatt-level hybrid station in the world. Previously, the largest hybrid station – with a capacity of 850,000kW – was in Qinghai province’s Longyang Gorge.

It is the first phase of the clean energy demonstration project in the Yalong River basin. The whole project had already met a 20GW capacity and was expected to reach about 50GW by 2030, state media reported.

“When the clean energy project is fully built, it will have a total capacity exceeding 100GW, producing approximately 300 billion kilowatt-hours annually, enough for 100 million households,” the Xinhua report said.

The Kela solar power station is significant in both scale and construction complexity.

There are 52,700 steel stakes supporting the solar panels that if connected end-to-end would stretch over more than 1,400km (870 miles). The steel used for the solar panel bracket weighs nearly 50,000 tonnes, enough to build another “Bird’s Nest” National Stadium in Beijing.

克拉电站是世界上第一个千兆瓦级混合电站。此前，最大的混合电站位于青海省龙阳峡，容量为85万千瓦。

该项目是雅砻江流域清洁能源示范项目一期工程。据官方媒体报道，整个项目已达到20GW产能，预计到2030年将达到约50GW。

新华社报道称，“清洁能源项目全面建成后，总容量将超过100GW，年发电量约3000亿千瓦时，足以满足1亿户家庭的需求。”

克拉太阳能电站无论是规模还是建设复杂性都非常大。

太阳能电池板由 52,700 根钢桩支撑，如果一端和一端连接，将延伸超过 1,400 公里（870 英里）。用于太阳能电池板支架的钢材重达近5万吨，足以建造北京另一个“鸟巢”国家体育场。

The station covers an area of over 16 sq km (6.2 square miles), comprises more than 2 million solar panels and its 1GW power output can fully charge 15,000 electric vehicles with a 550km range in one hour.

Because the power station site is in the high-altitude plateau of western Sichuan – 4,000 to 4,600 metres above sea level – construction workers faced extreme cold weather.

该充电站占地超过 16 平方公里（6.2 平方英里），由超过 200 万块太阳能电池板组成，其 1GW 的发电量可以在一小时内为 15,000 辆电动汽车充满电，行驶里程为 550 公里。

由于电站工地位于川西高原，海拔4000米至4600米，施工人员面临着极度寒冷的天气。

At that altitude, construction is only possible for less than half the year. At the most hurried time of construction, workers had to install 7,000 support bases, 1,200 solar panel brackets, 33,000 solar panels and 30 box transformers within 24 hours.

“Currently, the clean electricity produced by the station annually can satisfy the electricity demands of about 700,000 average households. It saves over 600,000 tonnes of standard coal annually, reducing carbon dioxide emissions by over 1.6 million tonnes,” Kela station project manager Yang Zhiwei told CCTV.

在这个高度，施工只能持续不到半年的时间。施工最紧张的时候，工人们要在24小时内安装好7000个支撑底座、1200个太阳能电池板支架、3.3万块太阳能电池板和30台箱式变压器。

“目前，该电站每年生产的清洁电力可满足约70万户普通家庭的用电需求。 每年可节省标准煤60万吨以上，减少二氧化碳排放160万吨以上。”克拉站项目经理杨志伟告诉央视。
