These projects not only improved Cambodia's energy structure, but also continued to inject new impetus into Cambodia's post-epidemic economic recovery.

Helping Thailand move towards a low-carbon society

On the Sirindhorn Reservoir in Ubon Ratchathani, more than 600 kilometers away from Bangkok, the capital of Thailand, seven huge blue square islands shine brightly under the sunlight. This is the largest floating photovoltaic project in Thailand jointly built by China and Thailand. Since it was put into commercial operation in October 2021, these Chinese-made panels have continuously converted sunlight into clean electricity and delivered it to thousands of households.

Relying on the Sirindhorn Dam hydropower station built in the 1970s, the newly completed floating photovoltaic and hydropower integrated energy project skillfully combines two types of renewable energy. According to reports, the feature of the project is that hydropower and photovoltaic power generation can be adjusted according to load changes. It can be powered by photovoltaic power during the day and hydropower stations at night, and can also generate power from photovoltaic and hydropower facilities at the same time, making long-term stable power generation possible.

Talking about the original intention of the project, Chachai, the assistant director general in charge of power station engineering and construction of the National Electricity Authority of Thailand, told Xinhua: "In order to cope with climate change, all countries are accelerating their progress towards carbon neutrality. Thailand also attaches great importance to the use of renewable energy for power generation, and Committed to developing low-cost, high-stability and eco-friendly green energy projects. Chachai said that the design of this integrated energy project is in line with their vision. Over the past year, the project has operated well under the condition of full-load power generation. In the future, this The pilot project will be rolled out to another 15 hydropower stations."

The Sirindhorn Dam floating photovoltaic project occupies a water area of about 121 hectares, which is equivalent to the size of 160 football fields, but only occupies about 1% of the total reservoir area. Suweta, one of the project managers in Thailand and director of the Control System Engineering Office of the Ministry of Hydropower and Renewable Energy of the Thailand Electric Power Bureau, said: "These floating photovoltaic panels do not use agricultural land and will not affect the development of local fisheries." In order to promote renewable energy Energy concept, after the completion of the project, the Electric Power Authority of Thailand will use it as a renewable energy learning center and turn it into a new tourist attraction. Through the specially built aerial landscape plank road and exhibition center, visitors can stop to enjoy the scenery of the reservoir and look at the spectacular floating solar panels.

Natamon is a resident near the reservoir, and has been in charge of the reception since the opening of the exhibition center. She said: "The popularity of this project is getting higher and higher. During the Songkran Festival, the number of tourists visiting every day is as high as 5,000 to 6,000. The influx of tourists has created more job opportunities for local people, and selling local products can be seen everywhere near the scenic spot. There are also product vendors and tourism service facilities.”

A few days ago, the Electric Power Authority of Thailand officially announced to promote the construction of the second floating photovoltaic project, which is located at the Ubon Ratchathani Dam in Khon Kaen Province in the northeast. It is reported that the new project will incorporate energy storage systems to further improve the stability of power supply. Thailand plans to achieve carbon neutrality by 2050 and net zero greenhouse gas emissions by 2065. The Thailand Electricity Authority mentioned in the latest renewable energy plan that it will increase the total power generation capacity of floating photovoltaic projects to 2,725 megawatts by 2037.

China and ASEAN have great potential for wind power cooperation

At the 26th United Nations Climate Change Conference (COP26), ASEAN countries released the "ASEAN Energy Cooperation Action Plan", which determined that by 2025, the proportion of renewable energy in the energy mix will increase to 23%, and the installed capacity of renewable energy will account for Raise the proportion of total installed capacity to the target of 35%. According to data from the ASEAN Energy Center, natural gas and coal will account for about 69% of ASEAN's newly installed energy in 2020, while the abundant renewable energy has not been effectively developed, and the proportion of newly installed energy is less than 5%. , of which wind energy accounted for only 1.36%.

PowerChina has built a large number of green power projects in Laos, Cambodia, Vietnam and other ASEAN countries, with a total capacity of more than 8,000MW, laying a solid foundation for these countries to achieve carbon neutrality goals. In 2021, PowerChina and Vietnam WTO Corporation reached a cooperation on the largest offshore wind power project in Southeast Asia so far. After the project is completed, the annual new power generation capacity will be about 1.1 billion kwh, which can meet the average annual electricity demand of 250,000 local residents. Saving about 450,000 tons of standard coal, reducing carbon dioxide emissions by about 880,000 tons, and significantly improving the power shortage situation in the local area and even in southern Vietnam as a whole, PowerChina has become the largest new energy power contractor in Vietnam.

Since Goldwind entered the ASEAN market in 2012, it has successively realized the delivery and operation of low-wind-speed wind turbine products in Thailand, Vietnam and other countries. Goldwind operates 4 wind power projects in Thailand with a total capacity of 107.5MW. The increase in the height of the tower can expand the utilization of wind energy in the vertical space, increase the power generation, and improve economic benefits. Goldwind took the lead in developing the steel flexible tower technology over 120m in China in 2012, and successfully applied it to the Thailand project located in the low wind speed and large shear area. So far, the first grid-connected project has achieved 10 years of stability In operation, the annual average utilization rate of wind farms has been higher than 99%. Dong Yinming, general manager of Goldwind Asia Regional Center, said: "As the government and society's awareness of carbon conservation and emission reduction continues to increase, and the cost of fossil energy continues to rise, relevant ASEAN countries have begun to actively adjust their energy structures. Overall, Southeast Asia is a In areas where the policy environment is relatively open and has great potential for wind power development, and where wind resources are relatively scarce, Chinese wind power companies have pioneered low-wind-speed technologies and accumulated rich experience, with strong international competitiveness.”

After more than ten years of low-wind-speed product development and iteration, Chinese companies have established a new energy industry covering the entire industrial chain and formed unique industrial advantages. Using Chinese products and Chinese technology can help Southeast Asian countries improve their ability to cope with energy shortages, and provide Local training of high-quality wind power professional and technical personnel. Against the background of global green development, Southeast Asian countries have become major players in China's energy cooperation along the Belt and Road market. In the next few years, Chinese companies will continue to work hard to develop the Southeast Asian market, provide better products and technical support for Southeast Asian countries, and become An important partner in energy cooperation among Southeast Asian countries.Editor/Ma Xue
