随着可再生能源大规模发展和并入电力系统，以及碳中和目标下化石能源机组的转型，电力系统对灵活性和可靠性的需求与日俱增。尤其近年来，国内外频现的电力危机、能源危机无不提醒着保障电力安全的现实紧迫性。各个国家和地区的电力市场设立了不同类型的容量回收机制，如容量市场机制、稀缺定价机制及容量补偿机制等。2022年，国家发改委、国家能源局发布的《关于加快建设全国统一电力市场体系的指导意见》（发改体改【2022】118号）发布一年多来，围绕“加快形成统一开放、竞争有序、安全高效、治理完善的电力市场体系”目标，容量成本回收机制建设稳步推进。 去年，国家发改委、国家能源局近期联合印发《关于建立煤电容量电价机制的通知》，容量补偿机制从无到有，现在朝着市场化的方向纵深发展。4月25日，国家发改委发布了《电力市场运行基本规则》（ 2024年第20号令），呼吁“逐步推动建立市场化的容量成本回收机制”，由“发电机组、 储能等”资源出力。容量市场应该可以开放给各类资源参与。此前，… View Summary +

Electrification is the name of the game Heat is a crucial element in almost every manufacturing process, whether it is in the heavy stuff of melting glass and steel or firing ceramics at scorching temperatures (800°C-1,500°C), producing chemicals (100°C-500 °C),… View Summary +

Unbalanced charging could put unnecessary stress on distribution grids The European Union’s Alternative Fuels Infrastructure Regulation (AFIR), which entered into force mid-April 2024, requires Member States to scale up the buildout of truck charging capacity and density starting in 2025.

近年来，热泵的推广和应用在我国发展较快，与其他国家一样，要实现清洁供暖的目标仍然任重道远，在采购供暖设备时，许多用户与供热商仍存在犹豫，其中认为热泵运行成本较高是主要因素之一。本文将简要探讨可能解决此问题的路径之一，进一步完善分时电价机制中的季节性差异，即季节性电价–通过调节季节性电价来降低用户电费，有助于缓解对运行成本的担忧，促进热泵的使用率，从建筑电气化层面来支持我国实现双碳目标。 2021年7月26日，国家发改委印发了《关于进一步完善分时电价机制的通知》(发改价格〔2021〕1093号)，倡导“进一步建立健全季节性电价机制”，为用户提供更明确的价格信号。更针对电采暖，提出了“季节性电采暖电价“政策指导，降低用电成本的同时更进一步推动热泵部署。自2021年来，许多省份已经响应号召，实施了季节性分时电价。随着更多的大规模可再生能源并入电网，提高建筑终端用能电气化水平可以有助于消纳电量，另外，制定季节性电价可以降低清洁采暖成本，保障民生供暖需求。因此，有必要考虑如何建立健全季节性电价机制。 与适用于… View Summary +

Across the United States, support for renewable energy is growing. Public opinion surveys regularly show that most Americans see the development of lower-emission energy sources as a priority. The U.S. government is looking to keep up this momentum to… View Summary +

I live in Missoula, Montana, a small college town tucked into the Rocky Mountains. We’re known for our outdoor access, not for our burgeoning restaurant scene. So when a new spot opens, there’s usually a lot of buzz. It’s exciting… View Summary +

Following several years of strong growth, heat pump markets slowed in Europe in 2023. In previous articles for Carbon Brief, we discussed this initial surge in 2021 and explored the impact of the energy crisis in 2022. Yet, despite… View Summary +

引言 欧盟电力市场改革是近几个月的热门话题。此次改革将修订一系列法律法规，包括欧洲内部电力市场法规和指令、能源监管机构法规以及批发能源市场一体化和透明度的法规。修订草案已经于2024年4月11日由欧洲议会全体会议投票通过。下一步，该草案将在未来的几周内经过欧盟理事会的投票后最终生效。虽还须经过欧盟理事会的正式采纳，但预计草案内容不会有太大的变化，我们就此契机介绍和分析欧盟电力市场改革。本轮欧洲电力市场改革内容广泛，本文主要聚焦在对容量补偿机制和与之密切相关的现货市场改革的讨论。… View Summary +

Heat pumps use electricity to transfer heat, making them an energy-efficient alternative to furnaces and air conditioners. In 2019, the state of Maine made residential heat pumps a core piece of its climate strategy and set a goal… View Summary +

Thanks to an increase in manufacturing development, electricity demand is rising faster than expected in the Southeast. As a result, Duke, Georgia Power and TVA are asking their regulators to approve a series of new gas-fired generators using reliability and… View Summary +
