In recent years, China has made great achievements in the fields of national trunk power grids, multinational networking, distribution networks, and Solar power system technology grid automation in 25 African countries.
In 2013, China completed the power transmission and transformation project with the highest voltage level, longest transmission distance and maximum transmission capacity in Eastern Africa.
In 2015, the Ethiopia-Kenya ±500 kV DC transmission project contract was signed. The project is the first multinational DC networking project in East Africa. It is of great significance to accelerate the interconnection process of power grids in East Africa, realize the coordinated development of East Africa's power infrastructure and grid interconnection, and promote the interconnection of power between North Africa and South Africa.
These towers and wire groups will be built into the first high-voltage DC multinational interconnected transmission network on the “African Roof”, which will not only benefit Kenya, but also provide more stable and low-cost electricity for Uganda, Tanzania, Rwanda and other countries.
In 2016, Egypt's EETC 500 kV backbone network transformation and upgrading transmission project also received favorable comments from local people.
In June 2018, some cities in Ethiopia completed the construction of the main project of the medium and low voltage distribution network project. The project will benefit nearly 80,000 residents in eight large and medium-sized cities in Ethiopia, and about 5 million people will enjoy a stable supply of electricity.
Construction benchmarking project sharing technical standards results
CLP Equipment Co., Ltd. integrates 100 construction and cooperation units in China's power grid technology, construction, equipment manufacturing, operation and maintenance, and joint operations. It only takes 22 months to complete the construction task of Ethiopia's GDHA 500 kV power transmission and transformation project. Shocked the locals.
This large-scale power transmission and transformation project, from technology, equipment to design and construction, was “shouldered” by the State Grid. It is the first large-scale power transmission and transformation project in China that uses China's complete power technology and equipment construction.
It is of great significance for the 'Chinese Standard' to go abroad:
While promoting technology “going out”, the State Grid actively promotes the transformation of superior technologies such as UHV and smart grid to standards. It has taken the lead in establishing a complete UHV AC/DC and smart grid technical standards system and leading the development of international standards. Actively participate in the work of international standards organizations and promote China to become a permanent member of the International Electrotechnical Commission (IEC). At present, the State Grid has initiated the compilation of 56 international standards in the IEC and IEEE, which has promoted the transformation of China's technological advantages into international competitive advantages.
China's Solar power system investment can benefit about 5% of the population (about 5 million) in Ethiopia, and the number of users accessing it is 80,000. The comprehensive line loss of medium voltage lines can be reduced from the previous 21.71% to 4.45%, effectively strengthening the local area. The stability and reliability of power supply significantly improve the operation level of the power grid system, accelerate the automation of information and power consumption of Ethiopia, and it is of great significance to alleviate the shortage of local power supply, promote local economic development and improve the living conditions of local residents.
Even Egypt has been greatly helped by China: China has not only transformed the local old power grid, but also boosted local employment.
China's State Grid has carried out more than 80 batches of assistance activities such as assistance to cultural and sports supplies, construction of simple roads, and renovation of domestic water facilities along the project construction, which has greatly improved the living standards of local residents.
In the future, China’s goal is great!
China has made great efforts to develop clean energy, including hydropower, wind power, photovoltaics, power grid construction, etc., and has established a complete standard system for clean energy power generation, forming a complete clean energy industry, which is green. The international power cooperation has laid a very good foundation.
“Belt and Road” green power cooperation key areas
From the perspective of traditional energy distribution, the oil and gas of the “Belt and Road” countries are generally distributed in the West Asia and North Africa region, and some are distributed in Russia, Mongolia and Central Asia. From the perspective of water energy, they are mainly concentrated in the surrounding areas of the Qinghai-Tibet Plateau, including China. And the five countries of the Indo-China Peninsula, India and Pakistan, the Mongolian Plateau and the Siberian region, as well as the Indonesian and Malaysian countries in the Indian Ocean also have a certain amount of water energy distribution; from the perspective of wind energy, Russia and Mongolia have rich wind energy, while Southeast Asia and The wind energy resources in the Central and Eastern European CIS and other regions are relatively common. In West Asia and North Africa, the Suez Bay region like Egypt is also one of the highest annual wind speed regions in the world. From the perspective of light, it is close to the equatorial region like Southeast Asia, South Asia and West Asia and North Africa. The solar energy resources are relatively abundant and have great development potential.
China can help many countries develop resources to meet the high-speed growth of electricity demand in Southeast Asia, South Asia and other countries.
In order to realize the development of power resources, China will actively develop renewable energy such as hydropower, wind power and photovoltaics. It will also guide other countries to learn from China's advanced technologies, develop clean and efficient coal-fired power, improve the energy efficiency of local regional units, and reduce pollutant emissions. .
China also hopes to connect the national grids! Promote interconnection with neighboring countries and regional power grids, promote the development and utilization of clean energy in various regions, and promote the further optimization of energy resource allocation.
China will also plan three phases of power investment and development in the future.
The first phase (2018-2025) is mainly aimed at regions with abundant energy resources and potential for future power development, such as Southeast Asia and South Asian countries, including Laos, Myanmar, Vietnam, Indonesia, Pakistan, Bangladesh, Nepal, etc. The development of clean electricity.
In the second phase (2025-2030), on the basis of summarizing the existing experience of power cooperation, we will further promote areas with good power development and greater willingness to cooperate, such as Russia, Kazakhstan, Mongolia, Saudi Arabia, United Arab Emirates, Areas such as West Asia and North Africa, which have abundant wind and photovoltaic resources, can actively develop renewable energy, and promote grid upgrading and interconnection.
In the third stage (2030-2035), some countries with more developed economies and some countries with higher demand for renewable energy will continue to explore the markets of these countries and promote China's technology and talent advantages in renewable energy. Green power cooperation.
Our country will use its rich experience to drive the development of other countries, and will also bring profits to domestic related industries and industries.
