Core Viewpoint - China has emerged as the world's first "Electric Empire," demonstrating remarkable stability in electricity supply amidst global energy crises, contrasting sharply with the struggles faced by other countries like the US, India, and Germany [1][2]. Group 1: China's Electricity Supply Stability - In July 2023, China's peak electricity load surpassed 1.2 billion kilowatts without any large-scale power cuts, while countries like India and the US faced severe electricity shortages [2][3]. - China's total electricity generation in 2023 reached an astonishing 9.46 trillion kilowatt-hours, more than double that of the US and three times that of the EU [2][3]. - The installed capacity of non-fossil energy sources in China surpassed 50% of total capacity for the first time in 2023, reaching 1.57 billion kilowatts, marking a 24.1% year-on-year increase [2]. Group 2: Strategic Planning and Infrastructure - China's electricity development follows a proactive planning approach, with major state-owned companies like State Grid and Southern Power Grid making long-term investments 5-10 years in advance [3][4]. - In 2023, China added 37 million kilowatts of new power generation capacity, bringing the total installed capacity to 2.92 billion kilowatts, significantly outpacing the US and Europe [3]. - The centralized dispatch system in China allows for efficient cross-regional power distribution, with 849.7 billion kilowatt-hours transmitted across regions in 2023, a 9.7% increase from the previous year [3][4]. Group 3: Technological Innovations - China has made significant technological advancements in the energy sector, including ultra-supercritical coal power technology, which achieves over 50% efficiency, far exceeding the global average of 35% [6][7]. - The country has built the world's largest molten salt tower solar power plant, addressing the intermittency issues of solar energy [7]. - China's ultra-high voltage transmission technology enables the efficient transfer of energy from resource-rich western regions to eastern load centers, with a total cross-regional transmission capacity of 188.15 million kilowatts by 2023 [7][8]. Group 4: Economic Implications - China's electricity cost advantages are reshaping global industrial dynamics, particularly benefiting energy-intensive industries like aluminum, where electricity costs account for 40% of total production costs [9][10]. - The disparity in electricity prices has led to a significant decline in European aluminum production, while China's share of global production has exceeded 60% [9]. - China's leadership in renewable energy positions it favorably in the green industry competition, with significant contributions to electric vehicle battery production and related supply chains [10]. Group 5: Global Influence and Cooperation - China's electricity advantages are translating into economic competitiveness, with the country exporting its energy solutions and technologies to regions like Southeast Asia and Africa [11][12]. - The concept of a "global electricity interconnection" is being pursued, aiming to connect China's grid with neighboring countries, potentially reshaping the global energy landscape [11].
