最“缺电”的经济大省，又放了个大招

Core Insights - The successful grid connection of the first unit at the Zhejiang Tiantai Pumped Storage Power Station marks a significant breakthrough in China's high-head, large-capacity pumped storage unit construction [1] - The power station, a key project during the 14th Five-Year Plan, has a total installed capacity of 1.7 million kilowatts, with the single unit capacity of 425,000 kilowatts being the highest in the country [1] - The station is expected to generate approximately 1.7 billion kilowatt-hours annually, enough to supply electricity for about 1.6 million people, while saving 520,000 tons of coal and reducing carbon dioxide emissions by 1.04 million tons each year [1] Group 1 - The Tiantai Pumped Storage Power Station is crucial for the East China Grid as a key adjustment power source, expected to be fully operational by the summer peak in 2026 [1] - The station's rated head of 724 meters is the highest globally, and its single-stage inclined shaft length of 483.4 meters sets a domestic record [1] - Pumped storage is increasingly vital as a mature and economically viable energy storage technology, serving as a key link in the new energy system [1] Group 2 - With the commissioning of this unit, Zhejiang's total pumped storage capacity has surpassed 10 million kilowatts, reaching 10.305 million kilowatts, making it the second largest in the country after Guangdong [2] - Zhejiang is accelerating the construction of a new energy system, with nearly 20 million kilowatts of pumped storage capacity planned and under construction, ranking first in the nation [2] Group 3 - Starting in 2026, China will shift from energy consumption dual control to carbon emission dual control, promoting a greener and more efficient energy production and consumption model [3] - Zhejiang, characterized as a resource-scarce yet energy-intensive province, faces high external dependency for energy supply, with one-third of its electricity sourced from outside the province [3] Group 4 - In the first ten months of this year, Zhejiang's total electricity consumption reached 608.8 billion kilowatt-hours, a year-on-year increase of 7.8%, the highest growth rate among major economic provinces in the country [6] - To enhance energy supply capacity, Zhejiang is diversifying its energy sources, including offshore wind power, pumped storage in mountainous areas, and nuclear power projects along the southeastern coast [6] - The approval of Zhejiang's first provincial ultra-high voltage AC ring network will create greater flexibility for electricity transmission and scheduling [6]
