Today (July 8), the world's largest hydro-solar hybrid power station, the Yalong River Kela Photovoltaic Power Station, officially started construction. A new model for the large-scale intensive development of renewable energy.
The Kela photovoltaic power station is located in Yajiang County, Ganzi Prefecture, Sichuan Province. The project is distributed between 4,000 meters and 4,600 meters above sea level in the western Sichuan plateau, covering an area of about 16 square kilometers, which is equivalent to the area of 80 bird nests.
The installed capacity of the power station is 1 million kilowatts, with a total investment of 5.3 billion yuan and more than 2 million photovoltaic modules.
Through a 500 kV transmission line, the Kela photovoltaic power station is connected to the Lianghekou hydropower station, which was just connected to the grid in March this year, to achieve water-solar complementarity.
Qi Ningchun, Chairman and Secretary of the Party Committee of SDIC Yalongjiang Company: After the power station is fully put into operation next year, it can provide 2 billion kWh of clean electricity every year, which is equivalent to saving more than 600,000 tons of standard coal and reducing carbon dioxide emissions by more than 1.6 million tons. .
Kola photovoltaic power station will also give full play to the advantages of local natural resources and cultural resources, and bring "multi-energy complementarity" to the local area by taking a series of measures such as "photovoltaic + characteristic industry", "photovoltaic + tourism", and "photovoltaic + infrastructure improvement". comprehensive benefit.
What is a hydro-solar hybrid power station? Yalongjiang has the answer!
Photovoltaic power plants rely on sunlight for power generation, and the power generation peaks at noon, but drops to zero at night, and the power generation will also decrease during cloudy days.
Therefore, due to the randomness and volatility of photovoltaic power generation, the generated electric energy cannot be directly connected to the grid and delivered to users.
The Yalong River Kela Photovoltaic Power Station perfectly solves this problem, because there is a super charging treasure nearby - Lianghekou Hydropower Station.
This hydropower station with an installed capacity of 3 million kilowatts can use its unique adjustment capabilities to realize the development of "water and light complementary".
First, the photovoltaic power station transmits the electricity to the Lianghekou Hydropower Station and becomes a virtual unit of the Lianghekou Hydropower Station.
Then, the hydropower station uses its powerful adjustment ability to smooth the randomness and volatility of the power generated by the photovoltaic power station, and provide stable, high-quality clean power for the grid.
Not only that, the Kola photovoltaic power station also fully considers the local grazing needs and increases the photovoltaic support to ensure the grazing space for cattle and sheep.
The coverage of photovoltaic modules can also reduce the evaporation of grassland water and improve the vegetation growth environment.
"Digital and intelligent" water-light complementary power station helps rural revitalization
Kela Photovoltaic Power Station is the first hydro-solar hybrid power station to be constructed since the "14th Five-Year Plan" of the Yalong River Basin Clean Energy Base. The scale of "water-solar complementarity" has been increased to one million kilowatts.
The connection of the Kola photovoltaic power station to the Lianghekou Hydropower Station has a leading role in achieving the "dual carbon" goal and helping to build a "green, low-carbon, safe and efficient" modern energy system.
