中国电力企业联合会统计与数智部电力供需分析处处长陈亚宁表示,今年入夏后,气温整体呈现出 梅早、高温开始时间早的特点,从6月中下旬负荷就快速增长,尤其是7月以来,全国多个区域及地方电 力负荷不断创新高,根据有关数据,7月4日、7日、16日、17日连创新高,最高达15.08亿千瓦,较去年 最大负荷增加0.57亿千瓦。除了气温因素,在国家"两新""两重"等政策加力扩围下,带动相关商品销 售、制造业投资较快增长,内需表现较为稳定,新质生产力成长壮大,工业生产、出口超预期回升。 陈亚宁表示,若夏季气温再创历史新高,则最高用电负荷可能达到15.7亿千瓦左右。8月份,将进 入电力保供的关键期,从目前国家气候中心的预测,结合宏观经济企稳回升的态势,迎峰度夏期间,全 国电力供需总体平衡,华东、华中、西南、南方区域个别省份短时供需紧张,但通过最大程度的跨省跨 区余缺互济后,可以实现电力平衡。 中新网北京7月30日电(记者 阮煜琳)中国电力企业联合会30日在北京发布《2025年上半年全国电 力供需形势分析预测报告》,预计今年迎峰度夏期间全国电力供需形势总体平衡。 报告预计迎峰度夏期间,全国电力供需总体平衡。综合考虑需求增长、电源投 ...

Core Viewpoint - The recent adjustments to time-of-use electricity pricing across various provinces in China aim to address the challenges of electricity supply and demand balance, driven by high electricity loads due to extreme weather conditions [1] Group 1: Time-of-Use Pricing Mechanism - Time-of-use pricing involves implementing different electricity rates during various times of the day, including peak, flat, and valley periods, to encourage users to optimize their electricity usage [1] - The policy has evolved since the 1980s, initially starting with peak and valley pricing, and has since incorporated peak, seasonal, and wet/dry pricing mechanisms [1] - Recent adjustments to the pricing mechanism are designed to facilitate the transition to a new type of power system, moving from a traditional "supply follows demand" model to an "interactive supply-demand" model [1] Group 2: Impact on Power Generation and Consumption - The new pricing signals aim to align user electricity consumption with the characteristics of renewable energy output, particularly addressing the mismatch between peak solar generation times and user demand [2] - Adjustments in pricing, such as designating midday hours as low or even deep valley pricing, help mitigate the issue of renewable energy curtailment [2] - Users are encouraged to shift their consumption patterns to reduce costs and enhance grid stability, as seen in the case of Hainan, where adjustments were made to address peak load challenges [2] Group 3: Implications for Renewable Energy Enterprises - The time-of-use pricing mechanism is expected to promote renewable energy consumption in the long term, expanding the development space for renewables [3] - However, in the short term, renewable energy prices may face pressure, potentially extending the payback period for investments in projects like distributed solar [3] - Recommendations for renewable energy companies include investing in energy storage, enhancing market trading capabilities, and exploring aggregated trading models for distributed projects [3] Group 4: Benefits for Electricity Users and Grid Companies - Electricity users can effectively reduce costs by optimizing their consumption strategies, increasing usage during low and deep valley periods [3] - Users are advised to manage energy consumption proactively, including optimizing production schedules and enhancing energy efficiency through digital technologies [3] - For grid companies, the time-of-use pricing mechanism alleviates peak load pressures and provides a flexible adjustment solution for maintaining supply-demand balance [4] - Advanced technologies like big data and AI can be utilized to analyze customer behavior and offer personalized energy solutions [4]
