中关村储能产业技术联盟·2025-07-24 08:25Core Viewpoint - The energy storage industry is experiencing significant growth in project bidding and winning, with a notable increase in both the number and scale of projects in the first half of 2025 compared to the previous year [1][2][3]. Group 1: Demand and Market Growth - In the first half of 2025, there were 1,291 energy storage bidding projects, a year-on-year increase of 27.3%, and 949 winning projects, up 13.9% [1]. - The number of winning bids for energy storage systems reached 401, reflecting a 40.1% increase, while EPC winning bids totaled 404, up 4.9% [2]. - The winning scale for energy storage systems was 11.2 GW/86.2 GWh, with a year-on-year surge of 278%, primarily driven by a significant increase in centralized procurement [2]. Group 2: Market Competition and Structure - The number of companies winning bids in the energy storage system market decreased by 31.1% year-on-year, indicating heightened competition [5]. - The top 15 companies in the EPC sector accounted for 38.2% of the total market, while the top 15 in the energy storage system sector only represented 20.6%, suggesting a more fragmented market [5]. - Major players like CRRC Zhuzhou Institute and Sungrow Power are leading the market, with a trend of battery manufacturers penetrating downstream system integration [5]. Group 3: Technology Trends - Lithium-ion batteries remain the dominant technology in EPC bidding, accounting for 93.7% of the total, an increase of 2.1 percentage points from the previous year [6]. - Flow batteries, particularly vanadium flow batteries, are gaining traction, with their market share rising to 5.5% [6]. Group 4: Procurement Trends - Centralized procurement has significantly increased, with 69% of energy storage system winning projects falling under this category, up 33 percentage points year-on-year [9]. - This shift towards centralized procurement enhances cost efficiency and supplier network establishment, while also intensifying competition among smaller firms [11]. Group 5: Regional Distribution - EPC winning projects are primarily concentrated in resource-rich regions such as Inner Mongolia, Xinjiang, and Ningxia, with significant activity also in clean energy provinces like Yunnan and Sichuan [13]. - Inner Mongolia leads in EPC project wins, supported by favorable local policies that incentivize energy storage projects [13].
