Google Earth Engine（GEE）——全球电厂数据库2016年

 全球电厂数据库
发布版本: 1.3, 发布日期: 2021-06-02¶
全球电厂数据库是一个开源的开放性数据集，包括在世界各地运行的电网规模（1兆瓦及以上）发电设施。

该数据库目前包含167个国家的近35000个电厂，占世界发电量的72%。条目仅在设施层面，一般定义为单一的输电网络连接点。目前还没有发电单元层面的信息。

创建数据集的方法在世界资源研究所的出版物《全球电厂数据库》中给出。
创建该数据集的相关代码可以在GitHub上找到。https://gee-community-catalog.org/projects/pwplants/www.wri.org/publication/global-power-plant-database

https://github.com/wri/global-power-plant-database 也可参见2020年初发布的关于改进的年发电量估算方法的技术说明。
