Proliferation and release to protect endangered species
Our reporter Zhu Dongjun
Noberto Vianna is a biological expert working in the fish farming center of the China Three Gorges (Brazil) Co., Ltd. (hereinafter referred to as "Three Gorges Brazil") at the Salto Hydroelectric Power Station.
One of the work of the center is to reproduce and release, and release the farmed fry into natural waters.
Since 1987, Vianna has been working here and has witnessed the improvement of the local environment by the release of proliferation.
On the Paranapanema River, a tributary of the Parana River, the Fish Farming Center of the Grand Salto Hydropower Station has 54 fish ponds with a water area of 20,000 square meters, and currently 7 species of local fish are cultivated.
"The places for replenishment and release are mainly in power station reservoirs and river tributaries. These places are conducive to the rapid growth of fish schools and are not easy to be preyed. After the release of local fish species, they can adapt to the local watershed environment and form a sustainable population." Vianna said.
In 2016, Three Gorges Brazil acquired the Great Salto Hydropower Station to further strengthen the operation of the breeding center.
Under the authorization and guidance of the Brazilian Institute of Environment and Renewable Resources, the center puts 1.5 million fry into the Parana River and 2.1 million fry into the Parana River every year.
"Our actions are of great significance to the preservation of biodiversity in the area and the expansion of fish resources. It also has economic and cultural value to the communities along the river. At the Tacuarusu Hydropower Station Reservoir on the Paranapanema River, we are proliferating The release action has made a freshwater fish that was once endangered become a catchable fish species again.” Vianna said that in recent years, the center has cooperated with universities and other scientific research institutions to study ways to promote fish population expansion. Local schools hold lectures and organize activities to allow students to participate in the release activities.
In 2018, the "Great Salto Hydropower Station Ecology and Fish Management Project" won the Best Practice Award in the 16th Brazil Sustainable Development Best Practices Appraisal.
"The protection of the environment is one of our priorities. The water environment is critical to clean energy production and the entire society. We have promoted some actions to protect biodiversity and sustainable development." Rogerio Mar, Environmental Manager of Three Gorges Brazil Keto said.
For example, the invasive species, golden mussel, has a strong reproductive capacity, which not only poses a threat to the environment, but also causes great damage to the water quality of the basin and water conservancy and hydropower projects.
Since 2017, Chinese companies have cooperated with a local biotechnology company to map the genetic map of golden mussels, trying to make genetically modified golden mussels and wild golden mussels bred by the next generation no longer have the ability to reproduce, so as to control their numbers and protect water ecology .
The results of this project are expected to be launched within a few years.
Monitoring and reusing aquatic macrophytes is also an important task.
Aquatic macrophytes are very important to the ecosystem. They can protect river banks, provide food and shelter for aquatic organisms, but their rapid and excessive reproduction will affect biodiversity and are not conducive to human activities such as navigation, fishing and hydroelectric power.
Chinese companies cooperate with local scientific research institutions to develop aquatic plant monitoring system and establish aquatic plant information database to provide decision-making basis for aquatic environment governance.
At the same time, aquatic macrophytes are also expected to be converted into biofuels.
"We are evaluating the application potential of different aquatic macrophytes to improve fuel quality and expand production scale." said Ricardo de Barros, an environmental analyst at Three Gorges Brazil. "In the future, our research results can be promoted in Brazil and abroad. Help solve the environmental problems caused by the overgrowth of aquatic macrophytes and convert them into energy."
"Recharge" for a sustainable future

Mendy, Wiltshire, is located 140 kilometers west of London, England. A heavyweight power project is making the town eye-catching.
On June 30, China Huaneng Group's Mendi battery energy storage project in England was officially put into commercial operation, and it has been running smoothly for more than 5 months.
This is currently the largest grid-side single battery energy storage power station in Europe, and it is also the first large-scale battery energy storage project built by a Chinese power company in a developed country.
Mendi’s battery energy storage project has an installed capacity of 100 megawatts, equipped with a 1-hour battery capacity, and its performance indicators have reached the international leading level.
"I think this is a very exciting project. It helps the locals reduce carbon emissions and promote the development of renewable energy. We welcome it," said Toby Sturgis, a cabinet member of the Wiltshire Council.
The main equipment of the project is manufactured and integrated by Chinese companies, with a localization rate of over 70%. It mainly participates in services such as peak shaving and fast frequency response of the British power grid, creating conditions for the British power grid to absorb more renewable energy and helping the country achieve 2050. The annual zero carbon emission target.
"The Mendy project originated from a'blackout'." Guo Jingyu, the chief representative of Huaneng Group in the United Kingdom, introduced that on August 9, 2019, a serious blackout occurred in the United Kingdom, which exposed the lack of flexibility in the power grid.
In recent years, the UK's renewable energy has developed rapidly. In 2019, its power generation accounted for more than fossil energy for the first time.
However, renewable energy sources such as wind and solar energy are intermittent and fluctuating, and the power grid must have greater flexibility.
Therefore, building a battery energy storage project that can quickly participate in peak and frequency modulation is one of the best choices to improve the flexibility and safety of the grid.
Chinese companies responded to this demand as soon as possible.
The Mendi project took only one and a half years from the start of construction to the commissioning, during which the adverse impact of the epidemic was overcome.
"In the construction and operation of the project, we always put the local ecological environment protection at the top of our work." Guo Jingyu said that before the project started, China invited experts to conduct a detailed and comprehensive ecological assessment of the surrounding environment and found a place about 400 meters north of the project site. Inhabit two rare butterflies-swamp leopard butterfly and red-backed small lycaen butterfly.
After assessment, the project will not cause adverse effects on the two butterflies.
However, the experts also found that a large-crowned newt inhabited a pond only 56 meters from the southern boundary of the project. In order to protect these "indigenous people", the project team installed a 1,200-meter-long installation around the site before starting construction according to the expert’s recommendation. Amphibian protection fence.
In the future, a large-crowned newt wintering nest made of native wood and stone will be built in the south of the site.
Chinese companies have also explored new business models and signed the first electricity purchase and sale agreement for battery energy storage projects in the UK market with Shell Europe Energy.
On October 10, the Mendy project ran smoothly for 100 days, and the performance indicators of the 40 battery energy storage subsystems of the entire station reached the design expectations, becoming the largest service provider in the British National Grid's dynamic control frequency modulation market.
The provision of dynamic control frequency modulation services has extremely high requirements on the power response time of the unit. At present, there are a total of 800 MW battery energy storage power stations in the UK that can meet this requirement.
In recent years, battery energy storage has become a key technology to promote renewable energy from alternative energy sources to main energy sources.
Under the global carbon emission reduction trend, battery energy storage projects may usher in explosive growth in the next five years.
The construction of the second phase of Mendi's project has recently started. After the project is put into production, it will further enhance the capacity of the British National Grid to accommodate renewable energy.
British trade envoy to China Wu Qiaowen said: "The Mendy Battery Energy Storage Project will become the largest lithium battery energy storage system in Europe and an important part of the UK's renewable energy industry. We welcome more Chinese investment. Not only is it conducive to the development of enterprises in the two countries, driving employment and economic growth, but also helping to build a better and greener economy."
Keep more natural and wild
Our reporter Liu Hui
In the morning, go for a stroll in the fresh-air woods, have a meal at a beautiful food center at noon, and go swimming in your spare time...In the near future, residents near the Sembawang Comprehensive Community Center in Singapore will be able to usher in such a leisure life scene.
The Sembawang Integrated Community Center project is located in the northern part of Singapore and is built near the mountain, with a total construction area of 152,000 square meters.
The original intention of its development is to build convenient facilities on the basis of the original natural environment, so that residents can enjoy nature while relaxing and entertaining.
In 2018, China State Construction (Nanyang) Development Co., Ltd. (hereinafter referred to as "China State Construction Nanyang") won the bid for the project.
As the project is located near a virgin forest, how to retain a large number of wild trees on the original site and integrate them into the planned community center has become a problem.
The project manager Wan Haitao said that during the construction preparation stage, China State Construction Nanyang carried out inventory, inspection, classification, and identification of the trees within the planning area, and invited arboriculture experts to evaluate it. During the construction period, the plan was adjusted several times. Protect trees as much as possible.
For example, a park area was originally designed with a trail through the woods, but in the early stages of construction, the builders discovered that there were many trees that were not marked on the drawings.
To this end, the Chinese company cooperated with the Singapore National Park Service to modify the design plan and adjust the location of the trail.
In this way, not only the vegetation in the area is preserved, but people walking on this tree-lined trail can also enjoy more natural and wild attractions.
For another example, the project was originally designed with a drainage ditch, but there are 6 big trees over 10 meters high in the construction area. In order not to damage the roots of the big trees, the Chinese company changed the location of the drainage ditch.
"In the spirit of respecting and protecting nature, more than 500 trees have been preserved throughout the project." Wan Haitao said.
In recent years, Singapore has focused on coping with climate change, continuously improving the environmental sustainability standards of buildings, and has set the highest level of green building mark certification-the Green Mark Platinum Award.
The Sembawang Integrated Community Center project aims to obtain the Green Mark Platinum Award and integrates the concept of green environmental protection throughout all aspects of project design and construction.
The roof of the building in the center is fully covered with soilless plants. In Singapore’s hot climate all the year round, this design is not only green in appearance, but also has the functions of cooling, sound absorption, and noise reduction; the rain drainage system in the garden area is used Stones, gravel, plants and other natural materials collect rainwater and filter the sedimentation layer by layer to create a natural river scene, which is both beautiful and can purify the water source; the project also uses a large number of prefabricated components, although the construction accuracy is proposed Very high requirements, but can minimize the construction waste generated during construction.
Looking through the project design drawings, the stadiums, gymnasiums, food centers and other buildings of various shapes are hidden in the greenery.
After completion, the Sembawang Comprehensive Community Center will also include clinics, elderly care centers, children's health centers, etc., covering the needs of residents of all ages in the community, and will bring great convenience to the lives of local people.
In this regard, the nearby residents are full of expectations.
Xu Wenyuan, the former head of Singapore’s Infrastructure Co-ordination Department, said: “This is an ambitious project and I hope it will become a gathering place to attract residents of Sembawang.”
From windmill to wind farm
Our reporter Liu Lingling
"How are wind turbines built?" "Why is the electricity generated by wind turbines called green energy?" ... Not long ago, the French BFM television station broadcasted a program during prime time. CGN European Energy") held a cloud opening event in the southern French city of Assac. The children who came to visit showed great interest in the working principle of wind turbines.
Under the leadership of the well-known French host, Charlotte Butrup, 250 local primary school students, farmers and Mayor Miria Vigrou, experienced the changes brought about by wind energy to this small city.
In the eyes of local residents, the Assak Wind Farm has brought green energy to power approximately 6,500 homes and promoted the sustainable development of the community.
In Assak, there is a trekking route called "From Wind Farm to Windmill", with a total length of 6 kilometers, which is the first trekking route through the small city.
“This road travels through time and space, connecting the ancient windmills and modern wind farms along the river, bringing new vitality to the town.” Viglu said, Chinese companies participated in the trekking route development work and sponsored the explanation. The sign of the fan.
At present, the Assak Wind Farm has been included in the local industrial tourism promotion project by the local tourism bureau.
"Assak City Government and Chinese companies also launched public welfare visits with the theme of exploring wind farms. As an industrial tourism project, Assak Wind Farm will certainly attract more people to visit and understand." Vigru said.
Not only in Assac, from the Charmont wind farm 200 kilometers east of Paris, to the floating offshore wind power pilot demonstration project on Groy Island in Brittany, which is under construction. Since its establishment in Paris in 2014, China General Nuclear Power With the development of wind energy as its core business, Euronergy has gradually developed into one of the major clean energy operators in France, creating jobs for the local society and promoting Sino-French clean energy cooperation.
Chinese energy companies are gradually opening up the market and establishing a good reputation in the local area, which is inseparable from the practice of green environmental protection concepts in the whole process of construction, operation and maintenance.
It is understood that these new energy projects all follow the environmental protection standard land planning and animal and plant protection measures. In the wind farm matrix design, it is better to reduce the installed capacity than to damage the species protection area.
Chris François, an environmental expert at China General Nuclear Power Corporation, said that the company will continuously monitor each power station, and do a good job in animal protection through regular shutdowns and installation of bird reminders.
"We have installed monitoring and audible alarm equipment to determine the risk of collision based on the bird species, distance, and flight trajectory monitored in real time to activate the alarm equipment to avoid the collision." François said.
In addition, these wind power projects also focus on reducing noise and visual pollution, and protecting biodiversity.
In the CGN European Energy Global Remote Monitoring and Data Analysis Center located in the La Défense business district of Paris, on two huge LCD screens, real-time data such as temperature, humidity, wind power, and power generation in 16 project locations in 7 European countries Keep jumping.
Up to now, CGN European Energy has a total installed capacity of 2.4 GW. In 2020, the on-grid power of new energy will exceed 5 billion kWh, which can power 2 million European households, reducing carbon emissions equivalent to planting more than 13,000 hectares of trees.
Since the official launch of the China-EU Energy Cooperation Platform project in 2019, China and the EU have achieved more substantive results in cooperation in the industrialization of clean energy technologies, market access, grid integration, and the use of renewable energy. Established European energy companies have carried out more and more cooperation.
