Core Viewpoint - The recent adjustment of time-of-use electricity pricing by Sichuan power companies, including Leshan Electric Power, is aimed at benefiting residential users, which is expected to significantly impact the companies' earnings in 2025 [1][3][4]. Group 1: Impact of Time-of-Use Pricing Adjustment - Leshan Electric Power announced that the new low valley pricing for residential users will lead to an estimated reduction of approximately 16.6 million yuan in its electricity business revenue for 2025 [3][4]. - The low valley pricing will apply to residential users with a "one household, one meter" policy, with rates set at 0.175 yuan/kWh during the low valley period in the wet season and 0.2535 yuan/kWh in the dry and normal water periods [3][4]. - Other Sichuan power companies, such as Xichang Electric Power and Guang'an Aizhong, also reported expected impacts on their earnings due to the new pricing policy, with estimated reductions of 5.55 million yuan and 39.38 million yuan in net profit for 2025, respectively [4][3]. Group 2: Company Performance and Market Reaction - Leshan Electric Power's preliminary net profit for the first half of 2025 is reported to be approximately 7.90 million yuan, while Xichang Electric Power expects around 3.10 million yuan [5]. - Despite the announced impacts of the pricing adjustments on earnings, the capital market has shown strong interest in Leshan Electric Power, with its stock price rising significantly from around 7 yuan to a peak of 18 yuan [5]. - The companies are also exploring new business opportunities, such as Leshan Electric Power's investment in a new energy storage project and Guang'an Aizhong's establishment of an investment fund focused on renewable energy [7].

Core Viewpoint - The recent adjustments to time-of-use electricity pricing policies across various provinces in China, particularly the designation of midday hours as low-cost periods, have significantly impacted the photovoltaic (PV) industry, leading to a decline in solar power profitability and forcing the sector to seek new avenues for revenue generation [1][5][11]. Group 1: Policy Adjustments - Multiple provinces, including Jiangsu, Anhui, and Hunan, have implemented or are in the process of finalizing time-of-use electricity pricing policies that classify midday hours as low-cost periods, with reductions in electricity prices by as much as 60% [1][5][6]. - As of now, over 20 provinces have adopted similar midday low-cost electricity policies, with some provinces setting the price as low as 0.12 yuan per kilowatt-hour [1][6][7]. Group 2: Impact on the Photovoltaic Industry - The new pricing policies have led to a significant decrease in the profitability of solar power projects, with internal rates of return (IRR) for some projects dropping from 12% to as low as 6% [10]. - The midday hours, which traditionally contribute about 40% of daily solar power generation, are now classified as low-cost periods, severely affecting the cash flow of solar power projects that lack energy storage solutions [9][10]. Group 3: Market Dynamics and Future Directions - The current time-of-use pricing mechanism is seen as an administrative measure rather than a market-driven approach, raising questions about its effectiveness in regulating the market [11]. - The photovoltaic industry is urged to transition towards a more integrated model that combines grid connection, self-consumption, and energy storage to adapt to the new pricing environment [12]. - Enhancing the capacity of the electricity grid to accommodate renewable energy sources is deemed essential for the sustainable development of the photovoltaic sector [14][15].

Core Viewpoint - The article discusses the recent adjustments in time-of-use electricity pricing policies across various regions in China, highlighting their significant impact on commercial and industrial energy storage projects [2][3][19]. Group 1: Time-of-Use Pricing Policy - In the first half of 2025, seven regions including Jilin, Sichuan, and Jiangsu officially updated their time-of-use pricing policies, while three regions issued drafts for public consultation [2][3]. - Key characteristics of the adjustments include changing midday peak periods to flat or valley segments, narrowing the fluctuation range, maintaining stable peak-valley fluctuation ratios, and more refined time segment divisions [2][4][15]. - The adjustments reflect local electricity supply and demand characteristics, significantly affecting the operational revenue of commercial and industrial energy storage projects [3][19]. Group 2: Trends in Pricing Policy Adjustments - Time segment adjustments have led to the midday peak being reclassified as flat or valley periods, with 22 provinces now implementing low valley pricing during midday [4][5]. - The fluctuation range has been reduced, resulting in smaller peak-valley price differences, as seen in Jiangsu where the previous policy allowed for broader price fluctuations [7][13]. - Most provinces did not adjust the peak-valley fluctuation ratios, with Jiangsu being an exception, increasing its ratios for different voltage levels [14]. Group 3: Electricity Grid Purchase Price Situation - From January to July 2025, the average maximum peak-valley price difference across 32 regions was 0.618 yuan/kWh, a 9.1% decrease year-on-year [16]. - The regions with the highest price differences were Guangdong (1.297 yuan/kWh), Hainan (1.053 yuan/kWh), and Hunan (0.975 yuan/kWh) [16][17]. - The adjustments in pricing policies, particularly in Jiangsu, have led to a significant decline in the economic viability of energy storage projects, with estimated daily electricity revenue dropping by 47% from the previous year [19][24]. Group 4: Impact on Commercial and Industrial Energy Storage Development - The changes in pricing policies, especially in Jiangsu, have posed challenges to the economic feasibility of energy storage projects, necessitating further market exploration and participation in virtual power plants and demand response initiatives [19][24]. - The rapid growth of renewable energy installations in Jiangsu, which reached over 100 million kW, has influenced the operational models of distributed solar + storage systems [24]. - The article emphasizes the need for thorough market research and monitoring of electricity supply and demand structures in major solar installation provinces to adapt to policy changes and market reforms [24].

Core Viewpoint - The provincial development and reform commission announced an optimization of the time-of-use electricity pricing policy, effective from August 1, aimed at enhancing the efficiency of electricity consumption and ensuring stable economic operations. Group 1: Policy Adjustments - The optimization includes adjustments to peak and valley time periods and an expansion of the execution range of the time-of-use pricing policy [1][3] - The new pricing structure divides the day into three segments: peak, flat, and valley, each lasting 8 hours [1][4] - The peak hours are set from 16:00 to 24:00, while the valley hours span from 00:00 to 16:00, allowing for a continuous 16-hour low-cost period [2][4] Group 2: Impact on Users - The adjustments are expected to lower midday electricity costs by reallocating peak hours, potentially releasing an additional 3 million kilowatts of electricity demand [2] - The reduction of peak hours includes the cancellation of peak pricing in September, resulting in a total decrease of 120 peak pricing hours annually [2] - The policy now allows commercial users with a capacity of 100 kVA or below to choose between time-of-use pricing or flat pricing, enhancing user flexibility [3] Group 3: Specific User Considerations - Hospitals, previously exempt from the time-of-use pricing policy, can now opt to participate based on their electricity consumption needs [3]
