午间谷电蔓延20余省，光伏被精准“猎杀”？

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].
