is building a 2,100 MW mega hydroelectric plant in Tibet

China has put the turbo into the energy transition towards renewables and for example, a button: only in 2025 will it install more wind electric capacity that the United States throughout its history. That same milestone but with solar panels He achieved it in 2023. But renewable energies have their problems and one of their critical points is storage: what to do with that surplus on a sunny and/or windy day? The answer normally (if there is no storage system) it’s wasting it. But China is also a specialist in mega-constructions, due to its colossal size, its blazing speed of construction or even for setting up facilities in places as inhospitable as a solar park on the tibetan plateau. If we combine these two ingredients we have the next great Chinese recipe: a mega hydroelectric plant in the middle of the Tibetan plateau. The project. Two years ago, the state-owned Yalong River Hydropower Development Company laid the foundation stone for the future Daofu hydropower plant, in the Garze Tibetan Autonomous Prefecture, in Sichuan (southwest China). This plant will have a total installed capacity of 2,100 MW and its infrastructure will consist of two reservoirs, a forced conduction system, an underground plant excavated in the rock and a surface substation. When operational, it will be the highest-altitude pumped hydroelectric power station in the world, surpassing by 700 meters the record-holder, the Yamzho Yumco Lake Pumped Hydroelectric Power Plant in the Xizang Autonomous Region. how to explain Xinhua, China’s official news agency. Why is it important. Fundamentally, because it solves the main bottleneck of renewables. Daofu is integrated into the Yalong River clean energy ecosystem, with a current operational capacity of 21,000 MW between hydro, solar and wind and with plans to reach 78,000 MW in 2035. Without mass storage, a significant part of that energy would be wasted or destabilize the network. On the other hand, it shows that it can be built in extreme conditions and its technical advances will serve to accelerate projects with similar characteristics. Finally, and hand in hand with the global energy transition, China takes a giant step in the global race for storage: it closed 2024 with 58 GW of installed pumping capacity, as the absolute world leader, and plans to overcome 120GW in 2030. Context. The production of renewable energy is becoming increasingly more affordable and simpler thanks to the democratization and evolution of technologies, but the Gordian knot continues to be storage: not wasting energy when more than necessary is produced and, conversely, how to cover demand peaks when there is no wind or sun. Storage is essential for a real energy transition and few countries are interested in it going well like China, which is the largest consumer of energy of the planet and world leader in renewable electricity production. Batteries are a growing solution, but pumped hydroelectric storage remains the technology with the highest cumulative installed capacity in the world and the most convenient to store large volumes of energy for hours. In figures. We have already glimpsed some of the overwhelming data of this mega-construction, but it leaves our jaws open: 2,100 MW of installed power, distributed among six reversible turbine-generators of 350 MW each. A quick comparison: Daofu represents almost 7% of all the wind power installed in the Spanish statebut concentrated in a single installation. 12.6 GWh of daily storage, which according to Xinhua meets the needs of two million households in Sichuan. 3 TWh of electricity generation per year, combining charge and discharge cycles. Between the upper and lower reservoir there is a difference in level of 760.7 meters, according to the construction company PowerChina Chengdu Engineering Corporation. The project investment is 15.1 billion yuan (at current exchange rates, about 1.84 billion euros). What is it like to build at 4,300 meters. At that altitude, the air available to breathe can cause hypoxia (less oxygen available) and temperatures plummet beyond freezing, a challenge for both working personnel and machinery. On the other hand, building in such remote areas represents a logistical challenge in terms of a lack of infrastructure, something to take into account when moving heavy material such as steel or concrete. Or to manufacture it there. As Yu Chuntao, project director of the PowerChina project, explains, to Global Times“The design, construction and manufacturing of electrical equipment for the Daofu project is highly exploratory and challenging” and that the advances made there “will greatly boost the design and manufacturing of pumping station equipment in China.” In Xataka | China needed space to power millions of homes, so it installed 2,934 huge solar panels in the open sea In Xataka | Germany has had a crazy idea to solve one of the problems of renewables: covering a lake with solar panels Cover | CGTN

China has a gigantic desert in Tibet with countless hours of daylight. And he’s filling it with solar panels

A year ago we had in Xataka how a huge solar park in the Chinese province of Qinghai, in the heart of the Tibetan plateau, served as an ecological experiment: under the panels, the shade retained moisture and made vegetation sprout in the middle of the desert. Today, that same place – the Talatan Solar Park – has become something much greater. It is the largest clean energy facility on the planet, a “blue sea” of silicon that already covers more than 600 square kilometers at three thousand meters above sea level. Where before there was nothing, China is lifting an energy ecosystem without comparison in the rest of the world. The scale has multiplied. Where last year there was talk of a 1 gigawatt solar park, today a complex extends that reaches 15,600 and 16,900 megawatts and continues to expand. Its area – between 420 and 610 square kilometers – is seven times that of Manhattan. Furthermore, it is not alone since 4,700 megawatts of wind energy and 7,380 megawatts of hydroelectric dams are deployed around it, completing an unprecedented hybrid system. The result: enough renewable energy to supply almost all of the plateau’s needs, including the data centers that power China’s artificial intelligence. According to CleanTechnicaevery three weeks China installs as many solar panels as the entire capacity of the Three Gorges Dam, the largest hydroelectric project in its history. A global clean energy laboratory. The Tibetan plateau, with its pure, cold air, has become the most ambitious energy laboratory in the world. There, China is experimenting with an electricity production model based exclusively on renewables. Electricity generated in Qinghai—40% cheaper than coal, according to the NYT— powers high-speed trains, factories, electric cars and data centers. In fact, the region is home to new computing centers dedicated to artificial intelligence, which consume less energy thanks to the altitude and low temperatures. “Hot air from servers is used to heat other buildings, replacing coal-fired boilers,” explained Zhang Jingang, vice provincial governor. In the words of Professor Ningrong Liu, in his column for the South China Morning Post: “China is not only leading the transition to green energy; it is building the 21st century energy scaffolding that sustains its industrial leadership in electric vehicles, batteries and solar technology.” Three sources that beat in unison. The magnitude of the project is only possible thanks to centralized planning that combines three main sources: solar, wind and hydroelectric energy. During the day, Talatan panels capture more intense solar radiation than at sea level; At night, thousands of wind turbines collect the cold breezes that sweep across the plains. When both systems fluctuate, hydroelectric dams balance the grid. Also, from the New York Times They described a system reversible pumping: excess solar energy during the day is used to raise water to reservoirs located in nearby mountains, which release that water at night to generate electricity. And under the panels, life returns. The shade of the plates reduces evaporation and soil erosion. According to China Dailythis year the vegetation has recovered up to 80% and 173 villages have benefited from the associated livestock farming. A local shepherd, Zhao Guofu, said: “My flock has grown to 800 sheep and my income has doubled since I grazed between the panels.” The perfect geography for the sun. No other country has taken solar generation to similar altitudes. The altitude plays in favor of physics, at 3,000 meters the air contains fewer particles that block light and the low temperatures reduce the thermal loss of the panels. This efficiency is multiplied in Qinghai, one of the few areas of the Tibetan plateau with large plains, where it is possible to build without the limits of the mountainous relief. The Talatan Desert, once an arid and worthless land, has become an energetic jewel. local authorities offer symbolic leases and have developed roads and high-voltage lines connecting the plateau with the industrial centers to the east. That energy travels more than 1,600 kilometers to factories and cities. According to CleanTechnicaChina already operates 41 ultra-high voltage transmission lines, some longer than 2,000 miles and up to 1.1 million volts. The global scale: no one comes close. Other countries have tried to generate clean energy at altitude, but with modest results. Switzerland, for example, inaugurated a small solar park in the Alps, at 1,800 meters, with barely 0.5 MW. For its part, in the Chilean Atacama Desert, a 480 MW project operates at 1,200 meters. By way of comparison, the Talatan complex multiplies the capacity of the Bhadla Solar Park in India, and for more than seven that of the Al Dhafra Solar Park in the United Arab Emirates, which until recently held records. The superpower of clean energy. China produces and consumes more renewable energy than any other country on the planet. In 2024, was responsible of 61% of new solar installations and 70% of global wind power. That same year, it achieved the capacity targets it had set for 2030. In the first six months of 2025added 212 GW solar and 51 GW wind, and the country’s carbon emissions fell for the first time. In this context, Talatan Park is both a symbol and an infrastructure. China is exporting its renewable technology around the world, from Asia to Africa, following the logic of Belt and Road Initiative. For the academic Ningrong Liu: “China wants to stop being the world’s factory to become the engine of the world’s factory.” It is not just about manufacturing panels, but about selling the complete model: engineering, financing and know-how to build green networks in other countries. The less visible side of the miracle. It’s not all clean energy and pastoral harmony. In its report, The New York Times recalled that access to Tibet remains strictly controlled by the Communist Party, and that Western media were only allowed to visit Qinghai on a government-organized tour. There are also human and environmental costs. CleanTechnica documents how the giant power lines that transport energy from west … Read more
