The market for stationary battery storage systems (BSS) has been growing strongly around the world for several years. The areas of application for BSS range from ancillary services, to reductions in commercial power prices, to an increase in solar self-consumption in private homes. This wide range of applications, combined with the strong market growth, has led to significant research in the field of BSS. The central topics of these research activities include the simulation of BSS in renewable energy systems, the development of operating strategies and the economic evaluation of these. However, the young market lacks transparency and the underlying assumptions about prices and battery dimensions often do not correspond to reality. To address this issue, this paper provides detailed information about the markets of home storage systems (HSS), industrial storage systems (ISS), and large-scale storage systems (LSS) in Germany. We have been continuously building a database on the HSS and ISS market with accompanying research on subsidy programs and additional research. Furthermore, we have compiled the dataset on LSS in parallel through constant research and publish it with this paper. Our analyses show that by the end of 2018, a total of 125,000 HSS, with a battery power of about 415 MW and battery capacity of 930 MWh, had been installed in Germany. The current state of the ISS database, however, does not allow sharp estimates on the overall German ISS market, but shows the wide capacity and power ranges from some kW / kWh to nearly one MW / MWh for these systems. The 59 LSS have an accumulated power of 400 MW and a capacity of about 550 MWh. They operate mainly in the market of frequency containment reserve (FCR). Lithium-ion technologies dominate the HSS and LSS markets with high shares. The specific prices of this technology have fallen by more than 50% in recent years and were around 1,150 €/kWh in the HSS market and 800 €/kWh in the LSS market in 2018. Our results provide a solid basis for further research on the current and future status of BSS. Research from around the world can adapt the results pertaining to Germany as one of the pioneering markets to other countries.

几年来，固定电池存储系统（BSS）市场在全球范围内增长强劲。BSS的应用范围从辅助服务到商业电价降低，再到私人住宅的太阳能自耗增加。广泛的应用范围以及强劲的市场增长，导致了BSS领域的大量研究。这些研究活动的中心主题包括可再生能源系统中BSS的模拟，运行策略的开发以及对这些方法的经济评估。但是，年轻市场缺乏透明度，有关价格和电池尺寸的基本假设通常与现实不符。为了解决这个问题，本文提供了有关家庭存储系统（HSS）市场的详细信息，工业存储系统（ISS）和德国的大型存储系统（LSS）。我们一直在建立有关高速钢和国际空间站市场的数据库，并伴随着有关补贴计划的研究和其他研究。此外，我们通过不断的研究并行地编译了LSS上的数据集，并与本文一起发布。我们的分析表明，到2018年底，德国已安装了125,000台HSS，电池功率约为415 MW，电池容量为930 MWh。但是，ISS数据库的当前状态无法对整个德国ISS市场进行准确的估算，但是显示出这些系统的容量和功率范围从kW / kWh到近一MW / MWh。59台LSS的累积功率为400 MW，容量约为550 MWh。它们主要在频率限制储备（FCR）市场中运作。锂离子技术以较高的市场份额占领了HSS和LSS市场。近年来，这项技术的具体价格已下降了50％以上，2018年在高速钢市场中的价格约为1,150欧元/千瓦时，在2018年低压钢市场中的价格为800欧元/千瓦时。我们的结果为进一步研究该技术奠定了坚实的基础。 BSS的当前和未来状态。来自世界各地的研究可以使有关德国作为其他国家的先驱市场之一的研究结果得到改编。我们的结果为进一步研究BSS的当前和未来状态提供了坚实的基础。来自世界各地的研究可以使有关德国作为其他国家的先驱市场之一的研究结果得到改编。我们的结果为进一步研究BSS的当前和未来状态提供了坚实的基础。来自世界各地的研究可以使有关德国作为其他国家的先驱市场之一的研究结果得到改编。
