One, the global market
In the first quarter of 2018, the installed capacity of the newly added electrochemical energy storage project was 94MW, which was a decrease of 37% year-on-year.
In terms of geographical distribution, the largest installed capacity of the UK's additional investment projects is 54.5MW, followed by the United States. The projects in the United Kingdom and the United States are mainly used in the field of ancillary services, which account for the UK and U.S. investment projects respectively. 99% and 60%.
From the perspective of application distribution, the installed capacity of auxiliary services is the largest, at 73.8MW, accounting for 79%, which represents a year-on-year increase of 228%. The user-side and centralized renewable energy grid-connected fields are ranked second and third, respectively. For 14% and 7%.
From the perspective of technology distribution, the largest installed capacity of lithium-ion batteries is 93.7MW, accounting for 99.7% of the total. It is distributed in various application areas and has the largest share in the field of auxiliary services. %.
Second, the Chinese market
In the first quarter of 2018, due to the relatively small installed capacity of China's newly put into operation electrochemical energy storage project, only the new planning/under construction projects are analyzed here.
In terms of regional distribution, new planning/projects under construction are mainly distributed in Xinjiang, Tibet, Jiangsu, and Inner Mongolia. Among them, Xinjiang and Tibet have the largest installed capacity of 100 MW, all of which are applied to centralized renewable energy sources. Web domain.
From the perspective of application distribution, in the newly-added planning/construction projects, the installed capacity of the centralized renewable energy grid-connected field is the largest, which is 200MW, accounting for 88%; the user-side and auxiliary service areas are ranked second and third. The percentages are respectively 8% and 4%. Among them, all applications of lithium-ion batteries in the field of centralized renewable energy grid-connected and ancillary services; the user-side field is mainly dominated by lead-acid batteries, accounting for 89%.
In terms of technology distribution, the newly planned/constructed projects are mainly based on lithium-ion batteries and lead-acid batteries. Among them, the largest installed capacity of lithium-ion batteries is 211MW, accounting for 93% of the total. The network, ancillary services, and user-side domains are all distributed, and their installed capacity in the area of centralized renewable energy integration is the largest, accounting for 95%.
