This is the supplementary data for the article "Estimating stranded coal assets in China's power sector" published in Utilities Policy. China has suffered overcapacity in coal power since 2016. With growing electricity demand and an economic crisis due to the Covid-19 pandemic, China faces a dilemma between easing restrictive policies for short-term growth in coal-fired power production and keeping restrictions in place for long-term sustainability. In this paper, we measure the risks faced by China's coal power units to become stranded in the next decade and estimate the associated economic costs for different shareholders. By implementing restrictive policies on coal power expansion, China can avoid 90% of stranded coal assets by 2025.

Context

There's a story behind every dataset and here's your opportunity to share yours.

The Global Power Plant Database is a comprehensive, open source database of power plants around the world.

Content

What's inside is more than just rows and columns. Make it easy for others to get started by describing how you acquired the data and what time period it represents, too.

It centralizes power plant data to make it easier to navigate, compare and draw insights for one’s own analysis. Each power plant is geolocated and entries contain information on plant capacity, generation, ownership, and fuel type. As of June 2018, the database includes around 28,500 power plants from 164 countries. It will be continuously updated as data becomes available. The most recent release of the Global Power Plant Database 1.1 includes the addition of two countries (China and Fiji), over 3,000 power plants, and nearly 1300 gigawatts of power capacity.

Mercury (Hg)-laden coal fly ash is an environmental concern when it is exposed to precipitation or surface/groundwater under natural conditions. In this study, fly ash samples collected from fifteen coal-fired power plants in Guizhou province of southwest China were subjected to examine the different Hg binding forms. The results showed that total Hg in fly ash from these CFPPs ranged from 30 to 870 ng/g. The percentage of different Hg binding forms in coal fly ash decreased in the following order: strong complexed form (64%–91%) > acid-soluble form (1%–25%) and sulfide form (3.4%–14.8%) > ion-exchangeable form (0.01%–8.1%), and water-soluble form (0.01%–4.4%). The low proportion of water-soluble and ion-exchangeable forms indicated that Hg was not easily removed under natural conditions. Furthermore, fly ash samples from three out of fifteen CFPPs were carried out the leaching experiments to disclose the leachability of Hg and the transmedia migration potential of this element. The results indicated pH dependence of Hg leachability, with more than 4-times fold higher Hg been leached out under acidic (pH < 5.5) and strong alkaline (pH > 13) conditions than under neutral and weakly alkaline conditions (pH = 7–12). In addition, Hg was leached out more in higher liquid/solid ratio than lower ratios. Nevertheless, Hg concentration in extract (<7 ng/L) of these three CFPPs under all conditions was well below the applicable regulation limits, and less than 0.11% of total Hg was leached out. This study demonstrated that Hg in the CFPP fly ashes was more stable under natural conditions when exposed to surface/groundwaters and had a negligible Hg leachability.

Methane is the second most abundant anthropogenic greenhouse gas. China is the largest methane emitting country in the world, greater than the combination of Europe and America. While coal mining represents half of China’s methane emissions, the amount and the trend of emissions remain controversial since 2010. With China stopping updating emission data after 2014, this compromises the accuracy of the trajectory of global methane emissions. Here, we provide a comprehensive inventory of coal mine methane (CMM) emissions from 2011 to 2020, by independently quantifying the weighted emission factors of more than 10000 mines.We would like to clarify that all data sources for this study are publicly available. The core dataset used in this study comes from the Compilation of National Coal Mine Gas Level Identification for 2011, which is a publicly available book published by the Chinese National Coal Mine Safety Inspection Bureau. This compilation includes detailed data on gas levels in over 10000 coal mines across China, which serves as the basis for our analysis of methane emission factors. Additionally, the provincial coal production data was sourced from the China Energy Statistical Yearbook, a widely accessible government publication that compiles annual statistics on coal production at the provincial level.We have uploaded the complete dataset to Figshare, which can be accessed via the DOI link. This ensures that all interested researchers can access the full data used in our study for replication and further analysis. We believe that these measures have improved the transparency and repeatability of our work.

Overview

The State Grid Corporation of China (SGCC) dataset with 1000 records was used in the model. This is a key resource in the field of power distribution and management, with a large and varied set of data about electricity transport and grid operations. This set of data contains a lot of different kinds of information, such as history and real-time data on energy use, grid infrastructure, the integration of green energy, and grid performance. It is a key part of making power distribution networks more reliable and efficient by helping with things like predicting demand, watching the grid, and finding problems. Researchers, energy providers, and law- makers can use this information to learn important things about electricity usage trends, the health of the grid, and the merging of green energy sources. This will help the electric power industry come up with new strategies and ideas that are based on data.

Power shortages are faced by developing countries in the Belt and Road region. Since the Belt and Road initiative was put forward, Chinese companies have invested and built a large number of electrical power projects in countries and areas with power shortages in this region. Due to the large number and wide distribution of projects and continuous increases in the number of new power projects, a large amount of project information has been generated. Accordingly, it is urgent to collect and summarize One Belt and One Road overseas power project information. In this study, web crawler technology was used to obtain overseas power project information. A One Belt and One Road dataset of overseas power projects was formed by further supplementing and improving the project information using documents from ministries, embassies, counselors of the ministry of economy and commerce, local news reports in Chinese and English, and case studies and field studies conducted by scholars and non-governmental organizations. The dataset includes information on 376 power projects from 80 countries in Asia, Africa, Europe, America, and Oceania. Each project’s information includes the project number, project name, construction status, enterprise name, installed capacity, continent, country, project category, and bid information. The collection and improvement of this dataset will help with understanding the distribution of One Belt, One Road overseas power projects, as well as development trends in overseas power investment and construction in recent years. This can provide a basis for China’s power companies to “go global” and become “One Belt, One Road” overseas. It also provides a reference for power project development planning and government department decision-making.
