In recent years, leveraging a complete energy storage industry chain, large-scale production, and continuously optimized manufacturing processes, Chinese energy storage enterprises have not only met overseas clients' requirements for efficient and stable operation of energy storage systems but also offered price advantages over local products, frequently securing large energy storage orders.
Integrated energy storage enterprises like Huawei and Sungrow have demonstrated even greater momentum in going global. Compared to battery manufacturers, these integrators can provide comprehensive one-stop solutions, optimizing system design, control strategies, and operation and maintenance management to deliver efficient and reliable energy storage systems, standing out in market competition.
Of course, it is worth noting that competition in the overseas energy storage market has become increasingly fierce. The overseas market is by no means a "safe haven" without challenges; in fact, it is a new "battlefield" full of uncertainties and difficulties.
From a positive perspective, the high-profit margins in overseas markets indeed offer domestic enterprises vast development opportunities. Companies can fully leverage their long-accumulated technological advantages and cost-control experience in the domestic market to achieve higher profits abroad. These funds can be continuously reinvested into critical areas such as R&D and product upgrades, helping enterprises secure a more advantageous position in the future global energy storage market.
However, in the journey of expanding into overseas markets, domestic enterprises also face a series of complex challenges. These include stringent market entry barriers and varying standards and certification requirements set by different countries and regions based on their energy strategies, safety standards, and industrial development plans, especially in mature markets like Europe and the US.
Moreover, while overseas markets are generally perceived to have higher gross margins, the actual costs of going global often exceed expectations.
Overseas clients have extremely high demands for the quality and reliability of energy storage products. Enterprises must continuously improve product quality and reliability, strengthen quality control and testing, and ensure the long-term stable operation of energy storage systems. This requires significant investments in human, material, and time resources to provide operation and maintenance services, posing higher demands on enterprises' technical and service capabilities.
As a result, industry insiders have called for caution, emphasizing that the overseas energy storage market is not suitable for price wars. Hidden costs and penalties cannot be ignored, and Chinese enterprises should unite and avoid excessive low-price competition.
The large-scale shift of domestic energy storage enterprises' focus to overseas markets is also driven by the intense cut-throat competition in the domestic energy storage market.
Public data shows that in the energy storage sector, the price of LFP energy storage battery cells has dropped from 0.9 yuan/Wh–1.0 yuan/Wh at the beginning of 2023 to the current 0.3 yuan/Wh–0.4 yuan/Wh. The average unit price of energy storage systems has fallen from around 1.5 yuan/Wh to 0.5 yuan/Wh–0.6 yuan/Wh, with some energy storage systems being awarded at prices below 0.5 yuan/Wh.
Recently, China Resources Power (836) held a bidding process for energy storage equipment procurement for the Xinjiang Tianshan North Slope New Energy Base Project. The lowest bid for a 4-hour energy storage system was 0.398 yuan/Wh, marking a historic low as it fell below 0.4 yuan/Wh for the first time.
"Rather than being caught in the cut-throat competition domestically, why not test the waters overseas?" This sentiment has become a true reflection of many energy storage enterprises.
This year, the domestic energy storage industry has experienced mixed results. While installation volumes have reached record highs, the ongoing price war has led many energy storage enterprises to see revenue growth without profit growth. Battery Network has observed that since November, several state-owned enterprises have successively launched centralized procurement for energy storage systems (battery cell frameworks) for 2025. Judging from the scale of centralized procurement, the energy storage market in 2025 is expected to remain robust, with bidding enterprises introducing new requirements for bidding rules, such as reducing the weight of price evaluation and increasing the weight of technical evaluation.
Currently, some bidding enterprises have explicitly stated that they will not accept inventory batteries or cascade utilization batteries. At the same time, they have introduced new standards for bidders' performance and technical requirements, including battery cell performance requirements, further curbing the potential for low-quality small producers to disrupt the market.
From an industry perspective, the rising thresholds for energy storage bidding can effectively address the issue of malicious price wars, screen enterprises based on their technical capabilities, and ensure the reliability of energy storage system operations. On the other hand, it can also accelerate the market exit of weaker players, promoting the healthy and sustainable development of the energy storage industry.
