For the kind attention of: The Chief Engineer (DP&T) 6th Floor, Central Electricity Authority (CEA), Sewa Bhawan, R.K. Puram, New Delhi-110066 31 March 2024 Background: We want to thank the Central Electricity Authority (CEA) for this opportunity to comment on… View Summary +
(A technical version of this paper, with four detailed appendices, is also available.) An increasing number of national, state and local government leaders recognize that rapidly decarbonizing the electricity grid is necessary to slow the disruptive effects of a… View Summary +
建筑领域绿色低碳转型是中国实现双碳目标的重要战略举措，在碳达峰碳中和“1+N”政策体系下，住房城乡建设部在2022年3月印发的《“十四五”建筑节能与绿色建筑发展规划》明确了“提高建筑能效水平，优化建筑用能结构”的基本原则，更提出了“推动零碳建筑”和“近零能耗建筑”的项目试点。应用高能效供热系统是降低建筑总体能耗的一主要方式。放眼世界，很多设有“净零碳”排放目标的国家也已经开始计划并实行各种建筑供暖脱碳策略。电能热泵供暖（下面简称“热泵供暖”）和氢能锅炉燃烧绿氢供暖（下面简称“绿氢供暖”）便是正在被各国考虑和讨论的供暖主要路径的两种选择。 热泵供暖是国内比较熟悉的取暖方式，而绿氢供暖虽然小众，但其讨论热度却在逐渐上升。当前，欧洲一些地区正在尝试采用绿氢供暖。对于绿氢供暖的成本效益和可行性进行深入讨论已成为热点议题，尤其在英国，应该推荐哪种技术作为主要供暖方式、其余方式又该提供多少政府扶助等相关争论在英国已经推进了一段时间。本文参考英国的相关研究和讨论，对热泵和绿氢采暖的能效性、经济性和可行性进行了对比和分析，并从中总结了两个可能会对其它设有净零碳目标的国家具有参考意义的观点： 热泵具有更高的能源利用效率，并且有助于减污降碳协同、建筑电气化，与电力系统清洁转型等工作推进。 热泵供暖的总系统成本较之绿氢供暖更低，能降低社会在供热转型上的经济负担。… View Summary +
Slovakia’s climate plans call for decarbonising buildings, shifting to clean technologies and reducing energy consumption. Fossil fuels currently provide 45% of heat and hot water in buildings, with biofuels and district heating — also fossil-fuel based — making significant additional… View Summary +
Im Jahr 2023 hat die Bundesnetzagentur in Folge europarechtlicher Anforderungen vom Gesetzgeber die Festlegungskompetenz für die Anreizregulierung zugewiesen bekommen – mittels derer die Regulierungsbehörden auf Basis umfassender Kostenvergleiche und Effizienzanforderungen Erlösobergrenzen für die Strom- und Gasnetzbetreiber festlegen. Nach einer… View Summary +
在全球能源格局的变革中，越来越多的国家意识到，通过热泵供暖器、热泵热水器、电炉等家用电器实现室内用能的电气化是一种更经济、更安全的减排脱碳路径。尽管天然气相对来说是较为清洁的能源选择，但仍然是一种会产生污染和碳排放的化石燃料。作为能源消耗的主要领域，建筑领域应该逐渐削减对天然气的依赖。… View Summary +
Shri Harpreet Singh Puthi Secretary Central Electricity Regulatory Commission (CERC) Chanderlok Building, 36 Janpath, New Delhi- 110001, India 10 Feb. 2024 Background We want to thank the Commission for this opportunity to comment on the Draft Notification (No.L-1/268/2022/CERC) on the… View Summary +
Stellungnahme zum Eckpunktepapier der Bundesnetzagentur Die gestiegenen Kosten des Stromnetzausbaus machen sich zunehmend in den Netzentgelten bemerkbar, die Bestandteil jeder Stromrechnung sind. Auswertungen zeigen, dass die verdichteten, städtischen Netzregionen günstiger sind als die ländlichen Netze. Aufgrund der Korrelation der Netzkosten… View Summary +
Electrifying long-haul freight across Europe can dramatically reduce emissions from transport to help meet climate goals. To advance the use of electric trucks, Member States will need to build more high-capacity charging, or ‘megawatt charging,’ infrastructure along core freight corridors. View Summary +
The Netherlands government has laid out ambitious plans to be climate neutral by 2050 and has engaged in multi-pronged efforts to meet this goal. It has successfully promoted the generation of renewable energy through the installation of utility-scale and household-level… View Summary +
国家发展改革委、国家能源局联合印发《关于建立煤电容量电价机制的通知》，决定自2024年1月1日起建立煤电容量电价机制，对煤电实行两部制电价政策。各个省已经制定了具体的细则实施容量电价，以期望减少煤电亏损，激励煤电支持保供，增加煤电灵活性改造。然而，除非这些容量补偿机制设计精准得当，否则可能导致不必要的风险，包括容量过剩、不合理的资源组合、过高的成本和排放，以及阻碍系统灵活性和减缓电力行业转型。… View Summary +
Brazil has excellent experience with policy regarding electricity accessibility. The Luz para Todos program, enacted in 2003, had connected 17.2 million rural Brazilians with electricity by 2023. But in some areas, particularly the Legal Amazon, challenges to electricity access persist. View Summary +
To add vast new amounts of solar, wind and other variable renewable generation, the electricity system will need to become far more flexible. Customers have a central role in achieving this, by adapting how and when they use electricity. This demand-side… View Summary +
