“塞上绿电”好风光 ——来自宁夏的调查

Core Viewpoint - Ningxia is leveraging its abundant renewable energy resources, particularly solar and wind, to transform its economy and establish itself as a leader in green energy development, with a significant focus on building a new energy system and enhancing the efficiency of renewable energy utilization [1][3][7]. Renewable Energy Development - Ningxia has become the first comprehensive demonstration zone for renewable energy in China, with a renewable energy installed capacity exceeding 50 million kilowatts, accounting for 62.6% of its total installed capacity [1]. - The region's solar energy utilization averages about 1,500 hours per year, while wind energy utilization averages around 2,000 hours per year, supported by vast unutilized land [1][2]. - The Ningdong Energy and Chemical Base features a 2 million kilowatt photovoltaic base that generates approximately 3.7 billion kilowatt-hours annually, saving about 1.15 million tons of standard coal and reducing carbon emissions by approximately 3.15 million tons [2]. Policy and Infrastructure Support - Ningxia has introduced several supportive policies to enhance the new energy system, including the implementation of a three-year action plan for green and low-carbon transformation [3]. - The region has established a new type of power system capable of 24-hour green electricity supply, addressing issues related to distribution network capacity and regulation [2][3]. - The construction of the first integrated wind-solar project and the first smart charging demonstration center in Northwest China has been completed, showcasing Ningxia's commitment to renewable energy development [3]. Power Transmission and Economic Impact - In 2024, Ningxia's renewable energy generation is projected to reach 61.3 billion kilowatt-hours, with 40.2 billion kilowatt-hours consumed locally and 21.1 billion kilowatt-hours transmitted to other regions [4]. - The "Ningxia to Hunan" ultra-high voltage direct current transmission project is expected to deliver over 36 billion kilowatt-hours annually, with more than 50% coming from renewable sources [6]. - The region's green electricity initiatives are expected to enhance its economic development while supporting energy supply in eastern and central China [4][6]. Technological Advancements and Challenges - Ningxia has made significant technological advancements in green electricity, achieving multiple provincial and national awards for innovations [7]. - The region's energy storage capacity has surpassed 600,000 kilowatts, ranking fourth in the country, which helps improve the controllability of renewable energy input [10]. - Despite the promising outlook, challenges remain in stabilizing the power system and ensuring effective integration of renewable energy sources [11]. Future Plans and Goals - By 2025, Ningxia aims to increase its renewable energy capacity by 20.6 million kilowatts and storage capacity by 600,000 kilowatts, while enhancing its power grid infrastructure [8]. - The region plans to develop 2,447 megawatts of new energy to support the green electricity needs of various industries, including modern coal chemical and data-intensive sectors [12].
