深山造“电池” 苍山变金山

Core Viewpoint - The successful grid connection of the first unit of the Zhejiang Tiantai Pumped Storage Power Station marks a significant advancement in China's pumped storage capacity, with the unit's capacity reaching 425,000 kilowatts, setting a new national record for single-unit capacity [1][2]. Group 1: Project Overview - The Tiantai Pumped Storage Power Station will have a total installed capacity of 1.7 million kilowatts upon completion, with all four units expected to be operational by July next year [1]. - The project is part of a broader initiative in Zhejiang to enhance energy storage capabilities, with the province's total pumped storage capacity reaching 10.305 million kilowatts, second only to Guangdong [2]. Group 2: Economic and Environmental Impact - The annual electricity generation of the Tiantai station is projected to reach 1.7 billion kilowatt-hours, saving approximately 520,000 tons of coal and reducing carbon dioxide emissions by 1.04 million tons [2]. - The project will provide stable revenue through capacity pricing and the sale of electricity at benchmark coal power prices, enhancing the economic viability of the investment [3][4]. Group 3: Technological Advancements - The Tiantai project has achieved three major breakthroughs in engineering technology, including the largest single-unit capacity in the country and the highest rated head in the world for a pumped storage facility [5][6]. - The use of high-strength forged materials in the construction of the power station demonstrates advancements in domestic manufacturing capabilities for hydropower equipment [6]. Group 4: Community Development - The construction of the pumped storage station has improved local infrastructure, including the development of a dual-lane road that significantly reduces travel time to the mountain top [7]. - The project has stimulated local tourism and economic activities, with nearby villages experiencing increased visitor numbers and income from local products and services [8].
