Distributed generation boosts energy storage installations of 24.2 GW

Recently, Zhongguancun Energy Storage Industry Technology Alliance released the "Energy Storage Industry Research White Paper 2016"
.
According to the White Paper, by 2020, China's total installed energy storage capacity will reach 24.
2 GW under the ideal scenario, and 14.
5 GW under the conventional scenario (in both scenarios, pumped storage is excluded).

According to the white paper, by the end of 2015, there were 327 energy storage projects (excluding pumped storage, compressed air and heat storage) in operation worldwide, with an installed capacity of 946.
8 MW
.
China has a total of 118 energy storage projects (excluding pumped storage, compressed air and heat storage), with a cumulative installed capacity of 105.
5 MW, accounting for 11% of the total installed capacity of global energy storage projects, and a compound annual growth rate (2010-2015) of 110%, which is six
times that of the world.

From the perspective of regional distribution, the United States still occupies the first position in installed capacity, as of the end of 2015, the cumulative installed capacity of the United States is 426.
4 MW (operating projects), since 2014, it has begun to surpass Japan and become the world's largest energy storage installed country, followed by Japan and China, accounting for 33% and 11%
respectively.

From the perspective of technical distribution, lithium-ion batteries occupy the first position
in the world's installed capacity in operating projects, under construction and planning projects.
The cumulative installed capacity of lithium-ion batteries accounts for 2/3
of the total installed capacity in the Chinese market.

On the application side, China is mainly in the field of distributed generation and micro-grid and renewable energy grid, the cumulative installed capacity of the two exceeds 80% of the Chinese market, especially the former, both in the cumulative installed scale and the number of projects occupy the first position, accounting for 56% and 77%
respectively.

Since 2013, energy storage has been increasingly used in renewable energy generation and microgrid projects, especially in the Chinese market
.
Zhang Jing, secretary-general of Zhongguancun Energy Storage Industry Technology Alliance, believes that there are four main reasons for this phenomenon: the state has formulated a very active rooftop photovoltaic development plan and given electricity price subsidies; Distributed projects are more suitable for energy storage technology participation at this stage in terms of cost and technical characteristics; From the perspective of international experience, the ultimate goal of distributed energy generation is spontaneous self-consumption, and the application of energy storage is essential; There are many innovation points and potential profit opportunities in the photovoltaic storage model, which is the area that investment and financing institutions pay the most attention to and are willing to participate in
.

Zhang Jing said that from the perspective of application and economy, there is still more room
for effort in the development of China's photovoltaic + energy storage model.
Policy support, including increasing the peak-valley electricity price difference, energy storage installation subsidies, energy storage electricity price subsidies, etc.
, is an indispensable factor for the construction of photovoltaic storage projects, and it is also expected that the new round of power reform that has been opened will provide a more flexible and market-oriented power application platform for the development of the energy storage industry, and realize more value
of energy storage as a fast-response power source.
