From January to September 2024, the country added <strong>210 million kilowatts<\/strong> of new renewable energy capacity, a 21% year-on-year increase, accounting for <strong>86%<\/strong> of total new power installations. Total renewable capacity now stands at <strong>1.73 billion kilowatts<\/strong>, representing about <strong>54.7%<\/strong> of China\u2019s total installed capacity\u2014a 25% increase from 2023. Key contributors include hydropower, wind, solar, and biomass.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">1. Non-Renewable Energy Sources<\/h3>\n\n\n\n<h4 class=\"wp-block-heading\">1.1 Thermal Power Generation<\/h4>\n\n\n\n<p>Thermal power remains the most widely used form of electricity generation in China. Power plants across the country use a variety of fuels:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Coal<\/strong>: The main source of thermal power in China.<\/li>\n\n\n\n<li><strong>Gas<\/strong>: A cleaner, but less common, alternative to coal.<\/li>\n\n\n\n<li><strong>Waste-to-Energy<\/strong>: Facilities that incinerate waste to generate electricity.<\/li>\n\n\n\n<li><strong>Cogeneration Plants<\/strong>: Plants that produce both heat and electricity, improving overall efficiency.<\/li>\n<\/ul>\n\n\n\n<h4 class=\"wp-block-heading\">1.2 Nuclear Power<\/h4>\n\n\n\n<p>China\u2019s nuclear energy capacity remains a steady contributor to the grid, primarily concentrated along the coast. Nuclear power currently accounts for about <strong>2.2%<\/strong> of China\u2019s energy, with projections of 120 million kilowatts by 2030.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\">1.3 The Potential of Nuclear Fusion<\/h4>\n\n\n\n<p>Nuclear fusion, though still in the experimental stage, is part of China&#8217;s long-term plan for sustainable, carbon-free energy. China has collaborated in the <strong>International Thermonuclear Experimental Reactor (ITER)<\/strong> project since 2006, with major domestic research efforts like the &#8220;artificial sun&#8221; project pushing the limits of fusion technology.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">2. Renewable Energy Sources<\/h3>\n\n\n\n<h4 class=\"wp-block-heading\">2.1 Hydropower<\/h4>\n\n\n\n<p>Hydropower capacity reached <strong>430 million kilowatts<\/strong> as of September 2024, with <strong>7.97 million kilowatts<\/strong> added in the first three quarters of the year. This includes conventional hydropower and <strong>4.98 million kilowatts<\/strong> of pumped storage. Hydropower production grew by 16%, reaching <strong>1004 billion kilowatt-hours<\/strong>, with an average usage of 2,672 hours.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\">2.2 Solar Power<\/h4>\n\n\n\n<p>Solar power has seen significant growth, with <strong>161 million kilowatts<\/strong> of new capacity installed from January to September 2024\u2014an impressive 24.8% increase over the previous year. By September, China\u2019s total solar capacity reached <strong>770 million kilowatts<\/strong>, marking a 48.4% year-on-year increase. This includes <strong>430 million kilowatts<\/strong> of centralized solar and <strong>340 million kilowatts<\/strong> of distributed solar. Solar power generation hit <strong>635.9 billion kilowatt-hours<\/strong>, a 45.5% increase, with a utilization rate of 97.2%.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\">2.3 Wind Power<\/h4>\n\n\n\n<p>Wind power also made strides, with <strong>39.12 million kilowatts<\/strong> of new capacity added in 2024 (including <strong>36.65 million kilowatts<\/strong> onshore and <strong>2.47 million kilowatts<\/strong> offshore). By September, wind capacity had reached <strong>480 million kilowatts<\/strong>. Wind power generation grew to <strong>712.2 billion kilowatt-hours<\/strong>, an increase of 13%, with a utilization rate of 96.2%.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\">2.4 Biomass Power<\/h4>\n\n\n\n<p>Biomass energy provides an important renewable option, with <strong>1.37 million kilowatts<\/strong> of new capacity added this year. As of September 2024, biomass capacity had grown to <strong>45.51 million kilowatts<\/strong>, generating <strong>153.8 billion kilowatt-hours<\/strong> in the first three quarters, a 4.3% year-on-year increase.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Power Demand and Load<\/h2>\n\n\n\n<p>China\u2019s power consumption spans multiple sectors, including industrial, residential, and transportation, with electric vehicles emerging as a notable consumer. Renewable sources, especially wind and solar, now generate <strong>1,349 billion kilowatt-hours<\/strong>, comparable to third-sector electricity use and surpassing urban and rural residential consumption for the first three quarters of 2024.<\/p>\n\n\n\n<ol class=\"wp-block-list\">\n<li><strong>Tier 1 Loads<\/strong>: Critical infrastructure such as hospitals and government facilities.<\/li>\n\n\n\n<li><strong>Tier 2 Loads<\/strong>: Key businesses and services where outages cause moderate disruption.<\/li>\n\n\n\n<li><strong>Tier 3 Loads<\/strong>: Less critical services experiencing minimal impact from interruptions.<\/li>\n<\/ol>\n\n\n\n<h2 class=\"wp-block-heading\">How Power is Transmitted: Grid Infrastructure<\/h2>\n\n\n\n<p>China\u2019s <strong>West-to-East Power Transmission Project<\/strong> supports transporting power from resource-rich western provinces to eastern demand centers. High-voltage transmission lines reduce energy loss and improve efficiency.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\">Key Components:<\/h4>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Substations<\/strong>: Voltage transformation points for effective long-distance transmission.<\/li>\n\n\n\n<li><strong>Transmission Lines<\/strong>: High-voltage lines and towers maintain stability over long distances.<\/li>\n<\/ul>\n\n\n\n<h4 class=\"wp-block-heading\">Distribution Networks<\/h4>\n\n\n\n<p>Operating at 35 kV and below, distribution networks deliver power from substations to end-users across urban and rural areas.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Reference<\/h2>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>\u56fd\u5bb6\u80fd\u6e90\u5c40<\/strong>.
