"山东的'五段式'电价让我们的储能项目峰谷套利空间翻倍，而浙江的新电价政策却让收益直接打七 折，不同省份的政策差异，让企业布局时得精打细算。"江苏瓦特储能技术公司负责人徐东的感慨，道 出了当前储能行业的普遍困惑。 今年以来，我国多地相继出台分时电价优化政策，通过调整时段划分、浮动比例、执行范围等核心要 素，用价格杠杆引导电力资源配置。一场以"市场化定价、动态化调整"为核心的分时电价改革，正彻底 重构储能行业的发展逻辑。曾经依赖固定峰谷价差套利的储能产业，如今站在"政策托底退坡、市场竞 争提速"的十字路口，如何在波动的价格信号中寻找新的盈利路径，成为全行业的核心命题。 电价信号引导产业布局 来源：中国城市报 "以前峰谷价差小，储能项目回本难；现在山东的深谷电价低至0.2元/千瓦时，尖峰电价冲到1.2元/千瓦 时，最大价差近1元，我们的工商业储能项目回收周期能缩短2—3年。"山东省青岛市某储能电站运营总 监王磊给中国城市报记者算了一笔"收益账"。作为电力市场化改革的先锋，山东省2025年全面推行"五 段式"分时电价，将全天划分为尖、峰、平、谷、深谷五个时段，工商业用户尖峰电价较平段上浮 100%，深谷电价下浮90 ...

Core Viewpoint - The recent adjustments to the time-of-use electricity pricing mechanism across various provinces in China aim to encourage off-peak electricity usage, alleviate pressure on power generation companies and the grid, and support the consumption of renewable energy [2][3]. Group 1: Time-of-Use Pricing Adjustments - Jiangsu Province has implemented a new time-of-use pricing structure that adjusts the pricing basis from user-to-door electricity prices to commercial user purchase prices, optimizing the peak and valley floating ratios [2][7]. - Other provinces like Shandong and Sichuan have also made significant adjustments to their time-of-use pricing mechanisms, with Shandong introducing a "five-segment" pricing system and Sichuan adjusting seasonal peak, flat, and valley durations [4][5]. - The adjustments are driven by the increasing electrification of demand and the growing share of renewable energy in the power system, necessitating a more dynamic pricing approach to reflect real supply and demand relationships [6]. Group 2: Impact on Users and Companies - The reforms are expected to benefit small and medium enterprises by allowing them to better manage production schedules and reduce energy costs, while also putting pressure on some renewable energy and storage projects to seek new value creation avenues [3][10]. - In Jiangsu, the new pricing mechanism is projected to reduce the peak-valley price difference from approximately 0.85 yuan/kWh to around 0.65 yuan/kWh, impacting the profitability of commercial storage projects [9]. - Companies like Xichang Electric Power and Leshan Electric Power have reported that the adjustments to the time-of-use pricing mechanism will negatively affect their operating performance, with estimated profit reductions of 5.4 million yuan and 8.5 million yuan respectively for 2025 [12]. Group 3: Future Market Dynamics - The introduction of a long-cycle settlement trial for the electricity spot market in Jiangsu is expected to create new opportunities for storage companies, moving away from a reliance on fixed peak-valley price arbitrage [10][11]. - The adjustments in time-of-use pricing are anticipated to lead to a more flexible and market-oriented operation of the electricity market, requiring companies to adapt their strategies accordingly [9][10].

Group 1: Overview of Time-of-Use Pricing Adjustments - The recent adjustments to time-of-use pricing mechanisms across various provinces aim to encourage off-peak electricity usage and alleviate supply pressure on power generation companies and the grid [1][2] - Jiangsu Province's new policy will implement a time-of-use pricing structure based on commercial users' purchase prices, optimizing peak and valley floating ratios [1][6] - Other provinces like Shandong and Sichuan have also made significant changes to their time-of-use pricing, with Shandong introducing a five-segment pricing system [2][3] Group 2: Impact on Users and Companies - The adjustments are expected to benefit electricity users by allowing them to manage production schedules more effectively and reduce energy costs [1][4] - However, some renewable energy generation and storage projects may face pressure on investment returns, necessitating new value creation strategies [1][7] - In Shandong, the implementation of time-of-use pricing has led to a significant increase in midday load, enhancing the consumption of renewable energy by 2.3 billion kilowatt-hours [4] Group 3: Specific Changes in Pricing Mechanisms - Jiangsu's new pricing mechanism will see peak prices increase by 80% compared to flat prices, while valley prices will decrease by 65% [6][7] - The adjustments in Jiangsu have resulted in a reduction of the peak-valley price difference, impacting the profitability of user-side energy storage projects [7][8] - The frequency of adjustments in time-of-use pricing is attributed to the increasing electrification of demand and the growing share of renewable energy in the power system [3][9] Group 4: Effects on Power Generation Companies - Power generation companies are also feeling the impact of the new time-of-use pricing, with projections indicating a reduction in net profits due to the adjustments [10][11] - Companies like Xichang Electric Power have reported expected decreases in revenue due to changes in peak and valley pricing structures [11] - The adjustments may not directly alter the grid-connected electricity prices but will influence long-term agreements between supply and demand sides, affecting overall revenue for power generation companies [11]

Investment Rating - The coal industry is rated as "Overweight" indicating a positive outlook for the sector [1]. Core Insights - The report highlights that the coal prices have reached the cost line for some mines, leading to an expected reduction in production. The supply side is constrained due to regular safety inspections and maintenance on major railways, which is anticipated to support coal prices during the off-season [1]. - The report emphasizes that while electricity demand is entering a low season, the combination of maintenance on railways and reduced import volumes is expected to stabilize coal prices [1]. - The report recommends several companies for investment, including China Shenhua, Shaanxi Coal, and China Coal Energy, which are characterized by stable operations and high dividends. It also suggests关注淮北矿业, 平煤股份, and 电投能源 for their undervalued potential [1]. Recent Industry Policies and Developments - The report notes that the Xinjiang coal transportation project has been approved, which will enhance coal transportation capacity significantly, thus reducing logistics costs and supporting energy security [5]. - The report mentions the implementation of a differentiated electricity pricing mechanism in Shandong to optimize power resource allocation [9]. Price Trends - As of April 18, 2025, the prices for various types of coal have shown mixed trends, with some prices remaining stable while others have seen slight declines. For instance, the price for Shanxi's main coking coal remains at 1380 RMB/ton, unchanged from the previous week [10][13]. - The report indicates that international coal prices have fluctuated, with Indonesian coal prices decreasing while South African prices have increased [11].
