成功组织绿电外送4.5亿千瓦时,"绿电"首次进京;首次实现通过"网对网"向山东、河北等地送电 30亿千瓦时;"填缝式"组织短期交易,额外挖掘短期外送70亿千瓦时……今年以来,陕西在成功应对省 内用电负荷创下4491万千瓦历史极值的挑战基础上,保持较高电力外送水平。据统计,11月28日,陕西 年度外送电量首次突破千亿大关,成为西北地区第二个电力外送量超千亿的省份。 "我们将统筹做好'网对网'集中式外送与'点对网'专用配套电源的协同管理,科学谋划'十五五'电力 外送规划,保障国家能源安全,为经济社会发展作出更大贡献。"蔡胜斌说。(记者 杨晓梅) 省发展改革委经济运行调节办公室主任蔡胜斌介绍,"十四五"时期,全国经济发展迈出新步伐,电 力需求稳步增长。陕西作为国家重要的综合能源保障基地,强化统筹调度、优化电力产业结构、提升电 力"含绿量",在保障省内用电需求的基础上,最大限度提供外送支援。 今年以来,省发展改革委将扩大电力外送规模作为稳定能源经济、助推高质量发展的重要抓手,协 同国网西北分部、国网陕西电力、陕西电力交易中心及在陕发电企业,拓展通道、扩大"版图",推动外 送电量跨越式增长。 截至12月27日4时,陕西 ...
如何让负电价红利传导到居民?专访中国能源研究会首席专家黄少中:在维持居民电价基本稳定的前提下 通过技术手段和机制创新实现负电价红利的间接传导

Core Viewpoint - The recent guidelines from the Central Committee emphasize the need for coordinated local consumption and external delivery of clean energy, aiming for high-quality development in the energy sector, while addressing the challenges of achieving peak coal and oil consumption by 2030 [1][2]. Group 1: Coal and Oil Peak Consumption - China's coal consumption has decreased from 68.5% in 2000 to 53.2% in 2024, while oil consumption has dropped from 22% to 18.2%, yet both still account for 71.4% of total energy consumption, indicating a challenge in reaching peak consumption targets [2][5]. - The coal industry is expected to peak before coal power, as coal power's peak is delayed due to its role in ensuring energy security and the reduction in coal consumption from other sectors like steel and cement [6][5]. Group 2: Energy Delivery and Storage - The primary solution for large-scale renewable energy consumption in the northwest regions is external delivery, as local consumption capacity is limited due to economic constraints and insufficient grid flexibility [7][8]. - The construction of external delivery channels faces challenges such as high costs and complex approval processes, which can lead to underutilization of built channels [9][10]. Group 3: Renewable Energy Investment - As of September, China's renewable energy capacity reached nearly 220 million kilowatts, with wind and solar power exceeding 170 million kilowatts, necessitating an annual addition of 19 to 20 million kilowatts to meet the 2035 targets [13][15]. - The recent market price decline for renewable energy has led to a cautious investment stance among power generation companies, particularly in the solar sector, due to the adjustments in pricing mechanisms [16][17]. Group 4: Addressing Negative Pricing - The frequent occurrence of negative pricing in the electricity market is attributed to supply-demand imbalances, and simply adjusting long-term trading ratios will not resolve this issue [18][19]. - To ensure that the benefits of negative pricing reach consumers, innovative mechanisms are needed, such as developing virtual power plants that aggregate consumer loads to respond to market conditions [20][21]. Group 5: New Energy Storage Development - The new energy storage sector is experiencing rapid growth but faces challenges such as low price competition and economic viability, leading to widespread operational difficulties [22][23]. - The government is working on reforms to allow energy storage to participate as an independent market entity, which includes integrating storage into capacity pricing mechanisms to ensure stable revenue streams [24].
