Baihetan hydropower station begins operation

KUNMING/CHENGDU, June 28 (Xinhua)

The first two generating units of the world's largest hydropower station under construction was put into operation on Monday, contributing to the country's green development and carbon-neutrality goals.

The Baihetan hydropower station is located on the Jinsha River, the upper section of the Yangtze River in southwest China, with an investment of 220 billion yuan (about 34.07 billion U.S. dollars).

With construction started in 2017, the hydropower station, which transmits rich power resources in the west to energy-consuming regions in east China, marks a major step in the country's utilization of clean energy.

Chinese President Xi Jinping on Monday sent a letter to the station, offering his congratulations on the launch of operations of its first two generating units.

As a major project in China's west-east power transmission program, the hydropower station is the largest and most technically challenging hydropower project under construction in the current world, said Xi, also general secretary of the Communist Party of China Central Committee and chairman of the Central Military Commission.

He expressed the hope that all builders and relevant parties would advance the station's follow-up work, and make greater contributions to achieving the country's carbon-peak and carbon-neutrality goals and promoting the comprehensive green transformation of economic and social development.

The hydropower station, which straddles the provinces of Yunnan and Sichuan, will have a total installed capacity of 16 million kilowatts. It will be equipped with 16 hydro-generating units, each with a capacity of 1 million kilowatts, the largest single-unit capacity in the world.

In the station's underground powerhouse, the first two such units are running steadily. All units are scheduled to be operational in July 2022 and will generate an average of more than 62.4 billion kWh of electricity every year, according to the China Three Gorges Corporation (CTGC), which built the station.

Upon completion, Baihetan will become the world's second-largest hydropower station in terms of total installed capacity, second only to the Three Gorges Dam project in the central province of Hubei.

When in full operation, the Baihetan project is expected to save approximately 19.68 million tonnes of standard coal and reduce carbon dioxide emissions by 51.6 million tonnes, sulfur dioxide by 170,000 tonnes, and nitrogen oxides by 150,000 tonnes annually.
..............

"The generator rotor -- a core component of the units -- weighs 1,955 tonnes, and can spin at 111 revolutions per minute and still remain stable, which ensures the long-term safe operation of the units," said Chen Hao, an engineer with the CTGC.

The Baihetan Dam is an ultra-high double-curvature arch dam with a maximum height of 289 meters and an arc length of 709 meters.

"All the core technologies of the Baihetan hydropower station are independently developed. The operation of the first generating units marks a breakthrough in China's construction of large-scale hydropower projects," said Lei Mingshan, chairman of the CTGC.

Ca a pas l' air d'être hydroélectrique, plutôt réservoir d'eau :
Chine. Deux barrages s’effondrent après des pluies torrentielles, près de 22 000 hectares submergés
avec Reuters. 19 juillet 2021

Des barrages avec une capacité de stockage combinée de 46 millions de mètres cubes d’eau se sont effondrés dimanche après-midi, en Chine.

Deux barrages se sont effondrés en Chine, dans la région de Mongolie-Intérieure (nord-est), après des pluies torrentielles, ont annoncé ce lundi 19 juillet les autorités chinoises.

Ces barrages, situés à proximité de la ville de Hulunbuir, se sont effondrés dimanche après-midi. Ils avaient formé des réservoirs d’une capacité combinée de stockage de 46 millions de mètres cubes d’eau, a indiqué le ministère des Ressources en eau.

Aucune victime signalée

Les personnes vivant en aval ont été évacuées, sans qu’aucune victime ne soit signalée, ont déclaré les autorités chinoises.

Le ministère a déclaré qu’en moyenne, 87 millimètres de pluie sont tombés à Hulunbuir au cours du week-end et jusqu’à 223 millimètres à la station de surveillance de Morin Dawa.

Les autorités de Hulunbuir ont déclaré sur la messagerie WeChat que 16 660 personnes ont été affectées, et que près de 21 708 hectares de terres agricoles ont été submergés. Des ponts et autres infrastructures de transport ont également été détruits.

Des images publiées sur les réseaux sociaux chinois ont montré que l’un des barrages a été complètement emporté par l’eau, inondant les champs voisins.

[L'industrie c'est fou] Imprimé en 3D, ce barrage chinois sera assemblé sans aucune main-d'œuvre
Installé sur le plateau tibétain, un barrage hydroélectrique de 180 mètres de haut devrait devenir d'ici à 2024 la plus grande construction imprimée en 3D de la planète. Le chantier sera entièrement assuré par des machines, pilotées par des algorithmes d'intelligence artificielle.


Valentin Hamon Beugin 30 Mai 2022 Usine Nouvelle

Image

Qui arrêtera la folle course de l'impression 3D ? Grâce à cette technique de fabrication additive, des bricoleurs de tous horizons sont déjà parvenus à fabriquer des toilettes mobiles, des cœurs artificiels, des steaks végans, des lotissements entiers et même bientôt... Un barrage hydroélectrique. Erigé à Yangqu (Chine), cet ouvrage de 180 mètres de haut devrait ainsi décrocher la palme de la plus grande construction jamais imprimée en 3D, un record détenu pour l'instant par un immeuble de bureaux situé à Dubaï (Emirats arabes unis). La centrale attenante devrait être opérationnelle d'ici à 2024 et fournir ensuite environ 5 TWh d'électricité par an.

Un géant de l'énergie

Un chantier d'une telle envergure mobilise habituellement plusieurs centaines d'employés, soumis à un exercice physique éreintant. Sûrement plus par souci d'économie plus que par bonté humaine, les responsables du barrage chinois ont quant à eux décidé de dire adieu à la main-d'œuvre, pour se reposer exclusivement sur des robots. Complètement autonomes, diverses machines formeront la structure couche par couche selon un système de planification dopé à l'intelligence artificielle et testeront la solidité de la structure à chaque étape du processus. Les travaux progresseront ainsi jour et nuit, sans interruption.

Avec ce projet, la Chine confirme son statut de géant dans l'impression 3D comme sa place de leader dans l'énergie. A lui seul, le pays assure 31% de la production mondiale d'hydroélectricité, grâce à ses centrales gigantesques. Avec une capacité de 103,6 TWh (soit environ un quart de la consommation de la France), celle située sur le barrage des Trois-Gorges est d'ailleurs la plus puissante jamais construite.

Jinsha River Chuanyun Hydropower Development has completed construction and started operations at the 16GW Baihetan hydroelectric project in southwest China.

The Baihetan hydroelectric project is one of the six large-scale hydropower stations along the Yangtze River and was built on one of its tributaries, the Jinsha River.

It becomes the world’s second-largest hydropower station in terms of total installed capacity, only next to the Three Gorges Project, which is also on the Yangtze River.

The project features sixteen 1GW turbines, to generate an estimated 62.4 billion kilowatt-hours (kWh) of power annually.

It is expected to eliminate about 90.45 million tons per annum of coal and 248.4 million tonnes of carbon dioxide emissions annually.

Reuters reported that the 289m dam and its associated infrastructure are one of China’s biggest and most challenging engineering projects, citing Three Gorges Corp.

Jinsha River Chuanyun Hydropower Development is a joint venture between China Three Gorges (CTG) with 70%, Sichuan Energy Investment with 15%, and Yunnan Energy Investment with 15%.

The JV started construction in 2017, with an estimated total investment of CNY170bn ($24.38bn).

In June 2021, China Three Gorges (CTG) generated the first power from the project.

It is a major project in China’s west-east power transmission programme and will deliver electricity across the country to cities in the east.

In addition to power generation, the Baihetan hydroelectric project would also facilitate flood control, and improve navigation and sand blocking.

Une centrale STEP de 1.2 GW est terminée avec la connection des 4 turbines de 300 MW fournies par GE.
GE connects 1.2GW Jinzhai pumped storage hydropower plant to grid

By NS Energy Staff Writer 01 Feb 2023

Located in the Jinzhai County, Anhui Province, the Chinese hydropower plant is estimated to have an annual generating capacity of nearly 1.4 times Jinzhai's annual household power consumption and is expected to mitigate 240,000 tons of carbon dioxide emissions per year

GE Hydro Solutions, a part of General Electric (GE), has connected all four units of the 1.2GW Jinzhai pumped storage hydropower plant in China to the grid.

The Chinese hydropower plant has completed 15 days of trial operation and all units have achieved commercial operation, said GE.

GE Hydro Solutions was awarded a contract in 2017 by Anhui Jinzhai Pumped Storage Power, a subsidiary of State Grid XinYuan, to deliver four new 300MW pumped storage turbines for the Jinzhai hydropower plant.

Besides, the company was selected to provide generator motors and the remaining plant equipment for the Chinese pumped storage power plant.

The first two units of the hydropower plant were connected to the grid in October 2022.

Located in Jinzhai County in the Anhui Province, the Chinese hydropower plant is expected to save up to 120,000 tons of coal and mitigate 240,000 tons of carbon dioxide emissions per year.

The annual generating capacity of the Jinzhai hydropower plant is estimated to be nearly 1.4 times the annual household power consumption in Jinzhai.

GE Hydro Solutions president and CEO Pascal Radue said: “Pumped Storage is the largest source of energy storage that exists today, which can help stabilize the grid with the integration of wind and solar power.

“The Jinzhai pumped storage project now fully operational will provide for a huge amount of clean energy to China and will help stabilize the grid to ultimately help integrate more renewable energies in a reliable way.

“And the beauty of hydropower projects is that it is set to be operational for the very long term, about 80 years, meaning that the project will provide affordable energy for several generations to come.”

According to GE, pumped storage units will assist in grid stability by serving as giant batteries.

During surplus energy times, water is pumped from the lower to the upper reservoir. In times of demand, water from the upper reservoir is released to produce hydroelectricity as the water travels via the turbine, said GE.
