According to the latest data released by the national energy administration, in 2021, the development of non fossil energy will reach a new level, the construction of new power system will take a new step, and the adjustment of energy structure will be accelerated.
Specifically, in 2021, the installed capacity of renewable energy power generation in China will historically exceed 1 billion kw, the installed capacity of hydropower and wind power will exceed 300 million KW, the installed capacity of offshore wind power will leap to the first in the world, the annual power generation of new energy will exceed 1 trillion kwh for the first time, and continue to maintain the leading position; The cumulative installed capacity of pumped storage power stations in China has reached 34.79 million KW, the cumulative installed capacity of new energy storage has exceeded 4 million KW, the replacement power of new electric energy is about 170 billion kwh, and the charging facilities of electric vehicles are expected to be about 2.5 million.
The reporter reviewed that in the past month, a number of new energy and new power system projects have been completed and put into operation, providing a solid guarantee for energy supply this winter and next spring, and helping to achieve the goal of carbon peak and carbon neutralization.
As of December 30, 2021, the annual power generation of Wudongde Hydropower Station has exceeded 38.91 billion kwh, reaching the design value of multi-year average power generation.
Wudongde Hydropower Station is a major national project for the implementation of “power transmission from west to East”. The installed capacity of the power station is 10.2 million KW, a total of 12 water turbine generator units with a single unit capacity of 850000 kW are installed, and the annual average power generation is 38.91 billion kwh. It is estimated that 38.91 billion kwh of green power can replace a large number of fossil fuels, reduce the consumption of standard coal by 11.86 million tons and carbon dioxide by 32.29 million tons every year, which is equivalent to planting 85000 hectares of broad-leaved forest.
On December 24, 2021, Jiangsu Dafeng phase II 606300 kW offshore wind power project of Longyuan Power of national energy group realized full capacity grid connected power generation.
A total of 94 6.45 MW high-capacity offshore fans are installed in the project, with two 220 kV offshore booster stations and an onshore centralized control center. The total length of submarine cables laid exceeds 210 km. The operation of the project marks that the installed capacity of Longyuan Power of national energy group in Jiangsu offshore wind power has reached 2.18 million KW.
On December 30, 2021, Huaneng Dingzhuang 320000 kW surface photovoltaic power station in Dezhou was fully put into operation. Huaneng Dezhou Dingzhuang 320000 kW surface photovoltaic power station is the floating photovoltaic power station with the largest single capacity in the world (single capacity refers to the installed capacity of a single project in independent waters), and it is also part of the photovoltaic project of Huaneng Dezhou Dingzhuang “wind power storage integration” power generation base.
On December 30, 2021, Hebei Fengning pumped storage power station was officially put into operation for power generation. Fengning pumped storage power station plans to install 12 units with a single unit capacity of 300000 kW, with a total installed capacity of 3.6 million KW, an annual design power generation of 6.612 billion kWh and an annual pumped power generation of 8.716 billion kwh.
The pumped storage power station has created four world firsts, namely, the world’s first installed capacity, the world’s first energy storage capacity, the world’s first scale of underground powerhouse and the world’s first scale of underground cavern group. The project also realizes the connection of pumping and storage power station to flexible DC power grid for the first time, adopts the technology of large variable speed pumped storage unit in China for the first time, and systematically overcomes the key technology of super large underground cavern group construction under complex geological conditions for the first time, which provides an engineering model for the high-quality development of pumped storage.
On December 29, 2021, the first batch of units of Ulanqab new generation power grid friendly green power station demonstration project were successfully connected to the grid. The total construction scale of the project is 2 million KW, which is divided into 1.7 million kW wind power project and 300000 kW photovoltaic project, with supporting construction of 550000 kW × The 2-hour energy storage system is divided into 4 wind and solar energy storage units, with a total of 4 integrated booster energy storage stations and 1 intelligent joint dispatching center.
The project is the largest “scenery storage” integration project in China. It is also the first new energy station in China with energy storage configuration scale of gigawatt hour. The supporting construction of a new generation control system based on digital and artificial intelligence algorithm is of great significance for China to build a new power system and explore a new mode of new energy development and construction.
According to media reports, on December 22, the world’s first mpt-5kw long-life methanol fuel cell power station (hereinafter referred to as “MPT product”) jointly developed by MOH Technology Co., Ltd. and Toshiba energy systems and solutions Co., Ltd. was officially delivered to China iron tower Co., Ltd, Provide continuous and uninterrupted power guarantee for an off-line communication base station (hereinafter referred to as “Daguang Liuxihe station”) in Liuxihe Reservoir Section of Conghua District, Guangzhou.
It is understood that the core principle of MPT product technology is to use renewable and inexhaustible methanol (CH3OH) as the carrier of hydrogen. When in use, methanol is converted into hydrogen and “use as you make”. This technology effectively solves the pain points of hydrogen transportation, storage, filling and safety, and reduces the cost of hydrogen.
