这些蓄电所大多数有着统一的规格：1.99MW/8.128MWh。 在日本出海圈，它们被简称为"28系统"，是日本储能界供应量最大，最为主流的"硬通货"。 展位现场，金钱流动的声音清晰可见。 一边是有人在计算器上飞快地按着汇率，有人正对着手机那头的合伙人焦急地喊道："路条价格又涨了！现在一张开发许可（路条）的售价基本都过亿了" 半年就回本，现在去日本还来得及吗 在今年东京国际智慧能源周（Smart Energy Week）上，出现了一个非常反差的画面。 本应是科技含量十足的展商化身新宿街头的房产推介，在展板上密密麻地贴出彩色的小传单，上面印着地块的卫星图、复杂的单线图，一大半还盖上了的 鲜红色印章："商谈中"或"售完" 这些传单指向的是同一个主角："蓄电所"。这是一个非常有日本风格的称呼，实际上就是国内的储能电站。 这让日本这个在大储领域毫无存在感的国家，忽然成为了海外资本和中国设备商的淘金地。 另一边则是海外来的投资商试图深入询问东电（TEPCO）或关电（KEPCO）的并网检讨细节。 这一切都来自于一个"全球最高收益"的神话。圈内疯传：2024-2025年，第一批"蓄电所"做到了半年多回本，IRR冲到了45% ...

Industry Development - The energy storage industry is complex due to various technology routes, each with distinct advantages, disadvantages, and cost reduction curves, making the development path more intricate [1] - The introduction of the 136 document and the full market entry of renewable energy are expected to make economic benefits a crucial consideration for energy storage deployment, leading to the potential exit of low-quality, low-cost storage manufacturers [1] - The peak construction period for pumped storage is anticipated, with the performance of pumped storage main engine manufacturers expected to continue improving [1] Pumped Storage - Pumped storage is a mature energy storage technology that has seen development prior to the dual carbon strategy, but it does not directly produce electricity and incurs some losses [2] - The cost-sharing mechanism has historically constrained the development of pumped storage, but the implementation of a two-part pricing mechanism ("capacity price + energy price") by the National Development and Reform Commission has facilitated large-scale development [2] - According to incomplete statistics, the approved pumped storage capacity in China is projected to reach 70 GW, 65 GW, and 35 GW in 2022, 2023, and 2024 respectively, totaling 170 GW [2] Electrochemical Energy Storage - Electrochemical energy storage was initially seen as a key solution for the volatility of renewable energy but has faced frequent policy changes, leading to chaotic development and a market dominated by low-quality products [3] - The removal of mandatory storage requirements has resulted in a significant decline in storage revenues, with future earnings expected to rely on market arbitrage as the energy market fully opens [3] - Electrochemical storage has inherent advantages in frequency regulation, and as the frequency regulation market gradually connects with the spot market, it is expected to become another important revenue source for electrochemical storage [3]
