各地分时电价政策迎来密集调整

Core Viewpoint - The article discusses the optimization and adjustment of time-of-use electricity pricing in Guizhou Province, aiming to enhance the efficiency of electricity consumption and promote renewable energy development through a structured pricing mechanism [1][11][12]. Summary by Sections Guizhou Province Adjustments - The Guizhou Development and Reform Commission has proposed a new notification regarding the optimization of peak and valley time-of-use electricity pricing, which will allow industrial and commercial users to participate in floating pricing based on a reference price [1]. - The peak price will be set at a 60% increase over the base price, while the valley price will be set at a 60% decrease, resulting in an approximate 30% reduction in the peak-valley price difference [1][20]. - The adjustments will apply to industrial and commercial users under a two-part pricing system, including electric vehicle charging facilities and independent energy storage stations [1][17]. Implementation and Measurement - Users must install time-of-use metering devices to measure electricity consumption during peak, valley, and flat periods [4][21]. - The notification emphasizes the need for market transactions to align with the time-of-use pricing policy, requiring electricity sales contracts to reflect the specified floating price ratios [21]. Other Provinces' Adjustments - Jiangsu Province has announced changes to its time-of-use pricing structure, effective June 1, 2025, which will impact the profitability of distributed solar and commercial energy storage assets [7]. - Sichuan Province has also made adjustments, including seasonal differentiation in pricing and a dynamic adjustment mechanism for time-of-use pricing [8]. - Shandong Province has implemented a "five-segment" pricing mechanism to optimize electricity resource allocation and promote renewable energy consumption [9][10]. Future Outlook - The article suggests that as the new electricity system develops and energy consumption structures evolve, time-of-use pricing mechanisms will increasingly integrate with emerging technologies like energy storage and virtual power plants, facilitating a more flexible approach to energy management [12].
