（文章来源：每日经济新闻） 每经讯负电价今年以来出现频率逐步增加，并已在多地发生。它是如何产生的？会如何影响电厂收益？ 清华大学电机系副教授郭鸿业接受每经记者采访时表示，负电价是多重因素共同作用的结果，其形成与 电力供需在时空维度上的结构性失衡有关，既有新能源高比例规模化并网的必然性，也暴露出传统电力 系统调节能力的局限性。但他强调，即使现货市场出现负电价，发电企业仅需承担小部分电量的亏损， 整体收益仍能保持稳定或实现盈利。负电价不等于负电费，由于有高比例中长期合约的保障，在结算层 面不会出现发电主体真的"付费发电"的情况，至多是让出了一部分发电利润。 ...

就在临近今年国庆中秋长假之际，四川电力现货市场在进入结算试运行过程中出现了一个奇怪的现象—— 9月20日当天，省内电力现货价格出现全天负电价，出清最高价格为-34.8787元/兆瓦时（即-0.034元/度）， 最低价格为-50元/兆瓦时（即-0.05元/度），引发各界的热议。 此前负电价已在山东、浙江、内蒙古等多地发生，它是如何产生的？会如何影响电厂收益？明知电价为 负，发电企业为何选择不停机继续发电？ 《每日经济新闻》记者（以下简称每经记者）采访了多位发电企业、能源专家和高校学者，试图还原负电 价背后的真相。 负电价频率逐步增加 我国各地电力现货市场都会设置交易限价，多数省份最低限价为0元/度。部分允许价格为负的地区如山 东、内蒙古，此前就曾出现过负电价，这通常发生在电力供应过剩、市场需求不足的情况下。 每经记者梳理发现，近几年来，国内电力市场的负电价现象从零星出现到逐渐增多，并呈现"从单点到多 省、从短时到长时"的趋势。 2019年，山东电力现货市场在国内首次出现负电价——-0.04元/度的出清价格；2023年，山东电力现货市场 出现连续21小时负电价；2024年"五一"期间，山东电力现货市场出现连续22 ...

Core Viewpoint - The emergence of negative electricity prices in Sichuan is a reflection of the supply-demand imbalance in the electricity market, driven by an oversupply of electricity from renewable sources and a decrease in demand due to seasonal and economic factors [1][2][3] Supply and Demand Dynamics - Negative electricity prices in Sichuan reached -48.74 yuan/MWh and -49.26 yuan/MWh on September 20 and 21, respectively, with a cumulative duration of -50 yuan/MWh lasting 45 hours [1] - The supply structure in Sichuan is heavily reliant on hydropower, which accounts for 73% of installed capacity, while electricity demand has decreased by 18.1% year-on-year due to lower temperatures and economic adjustments [1] - Similar instances of negative pricing occurred in Shandong and Zhejiang, attributed to significant drops in electricity demand during holidays, despite high renewable energy generation [2] Industry Implications - The occurrence of negative prices is seen as a natural outcome of supply-demand dynamics, not a sign of market failure, and can serve as a signal for necessary adjustments within the industry [3] - Power generation companies are not necessarily losing money during negative pricing periods due to existing subsidies and mechanisms that provide financial stability [3] - The phenomenon encourages power generation companies to innovate, such as integrating energy storage solutions and enhancing flexibility in coal-fired power plants [3] Consumer Impact - Current residential electricity prices are not directly linked to market fluctuations, ensuring stability for consumers despite negative pricing in the wholesale market [4] - Experts caution that frequent occurrences of negative pricing could indicate structural issues within the energy system that need to be addressed through policy and market mechanisms [4] Recommendations for Improvement - Suggestions include promoting the synergy between energy storage and renewable energy, enhancing inter-provincial electricity transmission capabilities, and refining market governance mechanisms to mitigate the frequency of negative pricing [5] - The overall sentiment is that negative pricing should be viewed as a temporary challenge that can lead to positive industry transformation if managed effectively [5]
