让“负电价”发挥“正能量”
中国能源报· 2025-11-17 01:35
Core Viewpoint - The phenomenon of "negative electricity prices" is becoming more frequent in China's electricity market, driven by the rapid development of intermittent renewable energy sources and the improved operation of provincial spot markets. This indicates a potential oversupply of electricity, necessitating further optimization of the power system's adjustment capabilities [2][10][13]. Group 1: Occurrence of Negative Prices - In January, Zhejiang's electricity spot market reported a minimum price of -0.2 yuan/kWh, marking the first occurrence of "negative prices" in the region. In May, Shandong experienced negative price periods with a low of -0.08 yuan/kWh, and in September, Sichuan saw the first full-day negative price at -0.05 yuan/kWh [2][5]. - The increasing frequency of "negative prices" serves as a "signal light" for the electricity market, encouraging deep adjustments in power generation and investments in energy storage and other new entities [2][10]. Group 2: Implications for Power Plants - Power plants may report negative prices to enhance competitiveness during periods of oversupply, allowing them to sell electricity even at a loss. Renewable energy companies can still benefit from environmental credits, making it viable to sell at negative prices within acceptable ranges [5][6]. - Traditional coal-fired power plants face high startup costs and may choose to report negative prices to avoid shutting down, thus balancing their operational costs against potential future high-price periods [6][12]. Group 3: Market Dynamics and Policy Changes - The gradual relaxation of electricity price floors across various regions is contributing to the rise of negative prices. For instance, Shandong set a lower limit of -80 yuan/MWh, while Zhejiang proposed a range of -200 yuan/MWh for future market operations [11][12]. - The emergence of negative prices reflects significant changes in the supply-demand relationship within the electricity system, highlighting the scarcity of adjustable power resources [12][13]. Group 4: Future Trends and Recommendations - The frequency of negative prices is expected to increase in the short term, but with the deployment of flexible resources like energy storage, the occurrence may stabilize in the long run [13][14]. - To effectively manage negative prices, it is recommended to enhance market mechanisms, allowing for predictable and manageable fluctuations rather than completely eliminating them. This includes optimizing resource allocation and improving inter-provincial electricity trading [13][14][15].
近年来多地出现“负电价” 既然卖电“不挣钱”,为何电厂不愿停机?

Core Viewpoint - The emergence of negative electricity prices in China's power spot market, particularly in Sichuan, reflects a growing trend influenced by supply-demand imbalances and market mechanisms, raising questions about the implications for power generation companies and the overall energy market [1][2][12]. Group 1: Negative Electricity Prices - Negative electricity prices have been increasingly observed across various provinces in China, with the phenomenon evolving from isolated incidents to a more widespread occurrence [2][3]. - In 2019, Shandong was the first province to report negative electricity prices, with a clearing price of -0.04 yuan/kWh, and this trend has continued with significant durations of negative pricing in subsequent years [2][3]. - As of 2024, negative prices accounted for approximately 11% of the day-ahead market and 14% of the real-time market in Shandong [2]. Group 2: Causes of Negative Prices - The formation of negative prices is attributed to structural imbalances in electricity supply and demand, exacerbated by high penetration of renewable energy sources and limitations in traditional power system adjustments [5][6]. - Two main categories of causes for negative prices are identified: inherent negative prices due to high renewable penetration and mechanism-induced negative prices linked to specific market designs [6][8]. - Inherent negative prices occur when traditional power sources face operational constraints, leading them to offer negative prices to avoid higher costs associated with frequent start-stop cycles [6][7]. Group 3: Market Mechanisms and Impacts - The design of electricity market mechanisms, such as incentives for renewable energy development and long-term contract structures, can significantly influence the frequency of negative prices [8][9]. - High proportions of long-term contracts can stabilize overall revenues for power generation companies, even in the presence of negative spot prices, leading to a situation where negative prices do not equate to negative profits [11][12]. - The inability of retail electricity prices to respond effectively to wholesale market signals, particularly during periods of high renewable generation, prolongs the duration of negative prices without benefiting end-users [10][12]. Group 4: Future Considerations - The transition to a market-driven pricing mechanism for new renewable projects starting in 2025 may reduce the frequency of negative pricing, but the overall trend of negative prices may persist due to ongoing market dynamics [14][15]. - Experts suggest that a comprehensive understanding of negative prices, along with improved market design and monitoring systems, is essential to mitigate potential risks and ensure the stability of the electricity system [15].

Core Viewpoint - The National Energy Administration (NEA) emphasizes that the increasing frequency of negative electricity prices is a reflection of the growing share of renewable energy and the improved operation of provincial spot markets, rather than indicating that power plants are paying consumers [1][2]. Group 1: Negative Electricity Prices - Negative electricity prices are becoming more frequent due to the increasing proportion of renewable energy installations and the more robust operation of provincial spot markets [2][3]. - Negative electricity prices reflect a temporary imbalance in supply and demand, particularly when supply exceeds demand significantly, as seen in regions like Sichuan where supply was nearly 40% higher than demand [2]. - Short-term negative electricity prices can serve as a market signal to encourage adjustments in power generation and investments in energy storage [2][3]. Group 2: Impact on Power Plants - Negative electricity prices do not equate to power plants needing to pay consumers, as the overall impact on power plant revenues is limited due to long-term contracts and government subsidies [3]. - For instance, the average settlement price for hydropower in Sichuan was 183 yuan per megawatt-hour, which was higher than the monthly average of 177 yuan, indicating that power plants can still maintain profitability despite negative prices [3]. Group 3: Future Directions for Renewable Energy - The NEA aims to expand renewable energy supply significantly, with targets set for 2035 to have non-fossil energy exceed 30% of the energy mix and a total installed capacity of wind and solar reaching 3.6 billion kilowatts [4]. - Key initiatives include enhancing the integration of renewable energy, promoting offshore wind power development, and expanding distributed renewable energy applications [4][5]. - The NEA plans to improve market mechanisms to support high proportions of renewable energy, ensuring stable returns for investors while managing risks effectively [5].
