What Relyez does

Relyez (远信储能, Shenzhen Yuanxin Energy Storage Technology Co., Ltd.) is a China-based, privately-held battery energy storage system (BESS) provider founded in 2019 and headquartered in Shenzhen with manufacturing operations in Zhenjiang, Yao'an, Dali, and Jinchang producing over 10GWh of annual integrated capacity. The company designs, manufactures, and delivers integrated energy storage products — GridUltra (utility-scale 2-5MWh containers), VenturePro (100-418kWh commercial cabinets), RelyEZ Rack/Pack battery modules, and PowerXpert power conversion systems — built on proprietary liquid cooling and immersion cooling thermal management, VSG grid-forming inverter control (validated by a 58-second black start at the 150MW/300MWh Yongde project), and 314Ah LFP cell architecture. Relyez is ranked #2 globally in 2023 DC-side energy storage system shipments by CNESA, is a BloombergNEF Tier 1 manufacturer and S&P Global Top 10 BESS source supplier, and has delivered more than 10GWh of projects to over 100 customers across China, Africa, Japan, Southeast Asia, Europe, Americas, and the Middle East, with marquee clients including China Huaneng, China Resources, China Energy Construction, and Bimergen Energy.

The company operates a project-based enterprise hardware sales model augmented by subscription/managed services through its RelyEZ OS ecosystem platform (launched April 2026 at ESIE), which combines EnergyMarket+ for power trading decisions, EnergyNexusAI for AI agent orchestration, and EnergyHub EMS for station control — the platform manages over 3.5GWh of operational and托管 (managed) storage assets. Go-to-market combines direct enterprise sales to utilities and large C&I customers with strategic channel partnerships (Weihai International for Africa, international trading companies in Japan/Southeast Asia) and active participation in industry events (Africa Energy Forum, Smart Energy Week Japan, CIES). The revenue model spans hardware sales (primary), software/licensing (RelyEZ OS), and project development/system integration services. In 2026, Relyez has expanded internationally through the Bimergen Energy joint venture for 79.2MW of Texas ERCOT projects and deepened its Africa commitment via Weihai International, while vertically integrating into battery cell manufacturing through the RMB 1.299 billion Jinchang facility under construction.
