时隔两年，四川自5月1日起再次调整分时电价机制

Core Viewpoint - The Sichuan Provincial Development and Reform Commission has announced adjustments to the time-of-use electricity pricing mechanism, effective from May 1, 2025, to better align with seasonal electricity demand and supply dynamics [1][10]. Summary by Sections Adjustments to Time-of-Use Pricing Mechanism - The new mechanism introduces seasonal differentiated pricing, increasing summer peak hours by 2 hours and reducing low valley hours by 2 hours, resulting in summer peak, flat, and valley hours of 10, 8, and 6 respectively. For spring and autumn, low valley hours increase by 2 hours, while peak and flat hours decrease by 1 hour, leading to peak, flat, and valley hours of 7, 7, and 10 respectively. Winter hours remain unchanged at 8 hours [2][13]. - The peak pricing mechanism will see the cancellation of peak pricing in December and January, while the peak hours in July and August will be extended from 2 to 3 hours. A flexible peak pricing mechanism will be established, activating peak pricing on the third day if the maximum temperature reaches or exceeds 35°C for three consecutive days [2][13]. Suspension of Peak Pricing in Certain Areas - The peak pricing mechanism will be suspended in areas with limited electricity transmission, specifically in Panzhihua, Liangshan, Ganzi, and Aba prefectures [3][14]. Dynamic Adjustment Mechanism - A dynamic adjustment mechanism for time-of-use pricing will be established, which will regularly analyze the implementation of the pricing policy, the development of renewable energy, and changes in electricity load. The policy will be evaluated annually and adjusted based on the supply and demand situation in the province [3][14]. Impact on Commercial Users - The adjustments aim to guide commercial users in shifting their electricity usage to off-peak times, with a specific focus on reducing peak load pressures during summer. The changes are expected to lower overall electricity costs for commercial users by increasing low valley hours by 180 hours and reducing flat hours by 180 hours, while shifting 180 hours of high peak hours from spring and autumn to the lower-priced summer period [20]. Residential User Impact - The adjustments will not affect residential electricity usage, as the low valley pricing period for residential users remains unchanged from 23:00 to 07:00 the next day [16]. Implementation and Communication - The electricity grid companies are required to communicate the flexible peak pricing activation to users through various channels, ensuring that users can adjust their production plans accordingly [19].
