SINEXCEL has taken part in the 2026 edition of Smart Energy Week in Tokyo, showcasing its latest utility-scale energy storage solutions, including the 1375kW and StellaON 1250K/1575K PCS. Designed to accelerate the evolution of Japan’s utility-scale BESS market, these high-performance systems address the increasingly stringent requirements of grid stability and multi-market participation.
With Japan targeting 40%-50% of renewable energy by 2040, the 2MW/8MWh frequency regulation sector has become a critical battleground, the market demanding ultra-fast responsiveness and rigorous compliance.
The 1375kW PCS has emerged as a benchmark solution through the three core advantages of precision and speed, local adaptability and proven compliance, supported by comprehensive third-party testing and extensive local EMS integration experience.
Building on sixyears of local expertise, SINEXCEL has already delivered over 50 projects across Japan, including more than 10installations powered by the 1375kW PCS.
Complementing the 1375kW product, the company’sStellaON 1250K/1575K PCSis engineered to optimize project economics, safety compliance and grid integration.
Supporting multiple medium-voltage station configurations, the solution allows developers to scale efficiently while reducing installation complexity and lifecycle costs as set out below:
- 20ft 2.5MW~5MW MV Station
- 40ft 5.0MW / 6.25MW MV Station
- 40ft 9.45MW/ 10MW/ 12.5MW MV Station
During Smart Energy Week, SINEXCEL took the opportunity to formalize strategic partnerships through signing ceremonies with key Japanese stakeholders, including investor AI.net, EPC NOAH and service provider Sagacity.
By working closely with local partners, the company continues to strengthen its capabilities across project development, system integration and localized services, accelerating its long-term growth in the market.
With more than 17GW of installed capacity and over 5,000 projects across the globe, the company remains at the forefront of delivering mission-critical energy storage solutions, operating10 global service centres across Europe, North America and the Asia-Pacific region, enabling strong regional coverage and consistent service delivery.
