The Global and National Energy Systems Techno-Economic (GNESTE) Database: Economic and performance data for battery storage in current and future electricity systems

Here, we present a database which collates historical, current, and future cost and performance data and assumptions for battery energy storage systems from the open literature. Battery energy storage is the fastest growing form of power system flexibility, and will be critical to integrating large shares of variable renewable energy. The data are global in scope but with regional and national specificity, covers the years 2015 through to 2050, and span 671 datapoints from 18 sources. The database enables modellers to select and justify model input data and provides a benchmark for comparing assumptions and projections to other sources across the literature to validate model inputs and outputs. It is designed to be easily updated with new sources of data, ensuring its utility, comprehensiveness, and broad applicability over time. Technoeconomic data on utility-scale batteries was collected from websites, reports, academic articles and databases of national and international organisations.本研究构建了一套数据库，从公开文献中整理了电池储能系统（Battery Energy Storage Systems）的历史、当前及未来的成本、性能数据与相关假设。电池储能是增长最快的电力系统灵活性调节手段，对于高比例接入可变可再生能源至关重要。该数据库的数据覆盖全球范围，但兼具区域与国家特异性，时间跨度为2015年至2050年，共包含来自18个来源的671条数据记录。 该数据库可帮助建模人员选取并论证模型输入数据的合理性，同时提供基准参照，便于将相关假设与预测结果与公开文献中的其他来源进行比对，以验证模型输入与输出的有效性。该数据库设计为可便捷接入新的数据来源进行更新，以长期保障其实用性、全面性与广泛适用性。该数据库从官方网站、研究报告、学术论文以及国家与国际组织的数据库中收集了电网级储能电池（Utility-scale Batteries）的技术经济数据。
