In the energy storage market, the installed capacity is increasing while prices continue to decline. This creates a challenge for the market to accurately predict shifts in industry profits. Additionally, there is concern about a potential slowdown in energy storage installed capacity if the growth rate of photovoltaic (PV) installations diminishes next year. However, with the ongoing acceleration of the energy transition, there is optimism for sustained long-term growth in the energy storage industry.

国内市場は大規模エネルギー貯蔵に対して楽観的な見通しを持っており、来年の設備容量の大幅な増加が期待されています。今年の太陽光発電の設置台数は予想を上回ったが、市場は需要の高さから超過部分が来年の発電容量の前倒しとみている。国家エネルギー局（NEA）は、今年最初の3四半期の地上太陽光発電の設置容量が顕著に増加したことを示すデータを発表した。家庭用太陽光発電設備と産業用および商業用分散型太陽光発電も大幅な成長を遂げました。しかし、送電網の消費容量が限られているという懸念は依然として残っています。

Predicting next year's PV growth rate accurately proves challenging for the market. Historically, energy storage installed capacity has been assumed to be directly proportional to PV and onshore wind power installed capacity. If the PV growth rate slows down next year, there is apprehension that energy storage capacity may also decelerate. However, the reality contradicts these concerns as the growth rate in installed energy storage capacity far surpasses PV installations.

China's cumulative installed capacity for new energy storage projects exceeded 17.33 GW/35.80 GWh in the first half of this year. The data also revealed that China's new centralized PV installed capacity reached 37 GW in the same period. Between Q3 of 2021 and Q2 of 2023, China achieved a centralized PV installed capacity of 53 GW, accompanied by a corresponding energy storage installed capacity of 8.7 GW. Although the installed capacity in the first half of this year is lower than in previous years, the energy storage installed capacity remains comparable.

Several factors contribute to the positive forecasts for domestic energy storage installations next year. Independent energy storage installations unrelated to wind power are emerging as the primary driver of installed capacity. Hunan and Shandong played pivotal roles in driving the highest installations during the first half of 2023. The introduction of policies in Hunan province significantly fueled the rapid surge in energy storage installed capacity. Additionally, an increasing number of provinces now mandate energy storage as a requirement for new energy projects, further driving the growth of allocated energy storage.

Next year, even if the growth rate of PV installed capacity slows down, the optimistic outlook for domestic energy storage remains. The increased allocated proportion of energy storage, along with provinces mandating energy storage and the development of independent storage initiatives, contributes to this positive outlook. As the landscape of energy storage installations continues to evolve, the industry is expected to maintain its robust development. With the ongoing energy transition and the growing importance of energy storage, the market will likely see sustained long-term growth in the coming years.
