Shanghai TAOKE Energy Technology Co., Ltd. ("TAOKE Energy") has achieved new progress in the Japanese energy storage market. Two 2MW/8.16MWh high-voltage battery energy storage plants self-developed by the company in Shima, Mie Prefecture, and Chita, Aichi Prefecture, were successfully connected to the grid on April 17 and April 23, 2026, respectively. They will subsequently participate in the Primary Frequency Regulation (PFR) and peak-shaving markets.
Japan is accelerating its energy transition, targeting peak carbon by 2030 and carbon neutrality by 2050, with renewables projected to reach 36%–38% of its power mix by 2030. Given the inherent intermittency and volatility of solar and wind, real-time grid balancing is increasingly challenging, making battery energy storage an indispensable "balancing valve" for Japan's new power system.
Rather than traditional wholesale arbitrage, the core revenue for Japanese storage plants stems from Japan's unique supply-demand balancing market. Among these, Primary Frequency Regulation (PFR) currently offers the highest short-term value.
As the fastest-responding segment with the most stringent entry barriers in Japan's dispatch system, PFR demands exceptional technical standards. Failure to respond promptly results in market fines or trading suspensions. This dictates that energy storage systems must possess rapid, high-precision regulation alongside ultra-high reliability and long-term operational stability.
Backed by proprietary technologies, TAOKE Energy’s self-developed EMS utilizes a dual-module architecture and a five-layer fault-tolerant mechanism to ensure optimal performance, safety, and reliability. It delivers 100-millisecond frequency regulation response for precise energy management and intelligent dispatch. Standard equipped with SmartOM—our self-developed remote energy management platform—it safeguards full-lifecycle operations and provides investors with a solid technical foundation.
As an early mover in Japan, TAOKE Energy has secured a pipeline of over 1GWh of storage projects. With its Japanese subsidiary, Power Pool Co., Ltd., now operating multiple projects in batches, TAOKE's integrated "SI + EM + AG" service is gaining market traction. By 2026, the company expects to connect an additional 40 to 50 BESS plants to the grid.
