How China’s large-scale solar power plants change the world’s energy

December 11, 2023

How China’s large-scale solar power plants change the world’s energy
With the progress of science and technology and the development of society, human demand for energy is also growing. Traditional fossil fuels can no longer meet the needs of future social development due to limited resources and environmental pollution. In this case, clean energy has become the focus of attention. As one of the world’s largest carbon emitters, China has been actively seeking ways of energy transformation. Among them, solar power generation, as a clean and renewable energy, has been highly valued by the Chinese government. In recent years, China has made remarkable achievements in the field of solar power generation, and has built a number of large-scale solar power plants, which has a far-reaching impact on the global energy pattern. First of all, China’s large-scale solar power plants have huge power generation capacity. Taking Delingha photovoltaic(PV) power station located in Delingha City, Haixi Mongolian and Tibetan Autonomous Prefecture, Qinghai Province as an example, Delingha photovoltaic power station is currently the world’s largest single installed capacity photovoltaic power station. Covering an area of about 39 square kilometers, it can accommodate 9.3 million photovoltaic panels, with an installed capacity of 2.2 gigawatts and an annual power generation of 3billion kilowatt hours, which is equivalent to the annual power consumption of about 1million households. Secondly, China’s large-scale solar power plants have adopted advanced technical equipment and management means. For example, in the process of photovoltaic power generation, the photoelectric conversion efficiency can be improved by using efficient monocrystalline silicon photovoltaic modules; In terms of power transmission, the construction of smart grid can realize the effective dispatching and distribution of power, and improve the operation efficiency and stability of power system. In addition, China’s large-scale solar power plants have also promoted the development of related industries. Taking solar panel production as an example, China has become the world’s largest producer of solar panels. These panels are not only supplied to the domestic market, but also exported to all parts of the world, making an important contribution to the development of clean energy in the world. However, China’s large-scale solar power plants also face some challenges. For example, solar power generation is greatly affected by weather conditions, and stable power output is a problem that needs to be solved. In addition, the cost of solar power generation is still higher than that of traditional fossil fuels. How to reduce the cost of power generation is also a problem to be faced. In general, China’s large-scale solar power plants have played an important role in providing clean and sustainable energy, and also provided a reference for the global energy transformation. With the progress of technology and the support of policies, it is expected that China’s solar power industry will continue to grow and make greater contributions to achieving the goal of green and low-carbon economic and social development.

EU may launch solar energy import investigation

December 05, 2023

EU may launch solar energy import investigation
On November 29, more than 400 solar energy companies in Europe launched a joint appeal to urge policy makers to stop the trade investigation that may lead to the EU imposing tariffs on imported solar products. Before making this appeal, the head of the solar energy industry, state ministers and EU internal market commissioner Thierry Breton will hold a meeting on Friday to evaluate the measures to bring production back to Europe. Walburga hemetsberger, CEO of solarpower Europe, the European Photovoltaic Industry Association, said: "before the industry round table on Friday, we received worrying signals that the measure will include the investigation of import and export restrictions." European solar power companies participating in the joint appeal said that the signatories included 18 manufacturers and 28 national associations and research institutions. All parties agreed that tariff restrictions should not include imported photovoltaic products. The goal of the European Union is to reach 600 gigawatts of solar energy installed capacity by 2030, about three times that of 2022. The deployment needs to be significantly accelerated. The group said tariffs would only slow the process. They also expressed support for restructuring some solar manufacturing industries to achieve the EU's goal of 30GW capacity by 2025. Previously, the EU set restrictions on the import of solar panels, batteries and silicon wafers from 2013 to 2018 in China. Now, more than 90% of silicon wafers and components come from China.   The EU has launched a countervailing investigation on China's electric vehicles and will review foreign subsidies in the wind power industry to ensure that clean technology manufacturing is carried out in Europe and reduce dependence on China.

China's BRI installs 128 GW with growing renewables impact

November 28, 2023

China's BRI installs 128 GW with growing renewables impact
hina’s Belt & Road Initiative (BRI) marks a milestone with over 300 completed ventures boasting an impressive installed capacity of 128 GW. Despite challenges affecting certain projects, particularly in the realm of coal, the recent Wood Mackenzie report underscores the substantial growth witnessed in the renewable sector, with a specific emphasis on solar energy. Source: Wood Mackenzie Asia Pacific Power & Renewables Service   With an estimated investment of approximately US$200 billion, the BRI has become a key player in shaping the global energy landscape. Renewable energy projects, encompassing wind, solar, and hydro, have emerged as standout performers, constituting 68% of completed projects and 37% of total capacity. Notably, the share of renewables in newbuild capacity has risen from 19% a decade ago to 47% in 2022. The report highlights the increasing importance of renewable energy within the BRI, particularly in light of challenges faced by traditional coal projects. Alex Whitworth, Vice President and Head of Asia Pacific Power and Renewables research at Wood Mackenzie, notes, “The BRI’s influence on power markets is set to grow, with a further 80 GW already under construction or at the planning stage.” “China is changing its overall strategy, so we expect to see more focus on renewables, and more direct investment than the bilateral lending that was more common in the early years of the BRI”, he added.

Photo: Xinhua   The yearly pipeline of projects is estimated to be around 13 GW, with significant potential for increased wind and solar installations. Renewables are predicted to make up 57% of the planned capacity of 80 GW. Location-wise, Asia is the primary destination for BRI power projects, making up 75% of the total capacity. Pakistan, Vietnam, and Indonesia are the top three markets of BRI power projects out of a total of 72 countries. Looking forward, Asia and Africa are expected to continue to be the top two markets, representing 93% of the future projects. In addition to the great growth potential, the report also highlighted the challenges Chinese companies encountered in overseas power projects. To date, over 20% of projects have been cancelled or shelved, with a total capacity of 54 GW, which included 33 GW of coal, 12 GW of hydro, 6 GW of gas, 2 GW of solar, and 0.4 GW of wind. Coal power projects experienced the greatest impact, mainly due to shifts in policy and political pressure to curtail carbon emissions. The BRI project pipeline has been notably affected by China’s policy announcement in September 2021, stating a commitment to the ‘No new overseas coal power’ initiative. “Most affected projects were in Asia and Africa, with Asia contributing 60% and Africa contributing 32% of the total capacity,” said Whitworth.

Bloomberg New Energy Global Photovoltaic Power Station Development Costs Will Enter a Decline Again

November 22, 2023

Bloomberg New Energy Global Photovoltaic Power Station Development Costs Will Enter a Decline Again
On November 2nd, Kou Nannan, the head of China research at Bloomberg New Energy Finance, shared a report on "Global Development Trends and Key Market Prospects for New Energy" at the 2023 New Energy International Cooperation Forum. For the prediction of future global photovoltaic installation, we believe that the growth in 2023 is very significant compared to 2022, and the Chinese market is the largest. By the first three quarters of this year, China's photovoltaic installation has reached 130 million kilowatts, with a conservative estimate of 170 GW throughout the year, even reaching over 190GW. China's photovoltaic growth is very good.   Whether it is distributed photovoltaic or centralized photovoltaic in Europe, the growth of the European photovoltaic market is relatively good, with a clear growth range in several key countries.  The growth of the photovoltaic market in the United States has been slightly slower this year. With the implementation of some detailed regulations after the Anti Inflation Act, the photovoltaic market in the United States will have a good development in the coming years.   The cost of developing photovoltaic power stations will enter a downward trend again this year.   The focus is more on component prices, which have been reduced to a very low component in the overall development cost. Especially in the European and American markets, the cost of grid connection is higher. From the perspective of photovoltaic grid connection in the United States, data from 2021 to 2022 can be seen that the cost of grid connection is increasing for both photovoltaic and wind power. Analyzing the reasons, it can be seen that there is insufficient investment in the US power grid, and there is also a problem of insufficient investment in the European power grid, posing huge challenges to the development of new energy.   The cost of household photovoltaic market has also shown a significant decrease, while according to data released by Germany and the United States, the overall household cost is showing an upward trend. It is unclear whether energy storage is included behind this trend. But from the changes in numbers, it is found that energy storage will become a new growth point for market demand in the future on the household side.   For more photovoltaic consulting and products, please log in www.rongstar.com
