HNAC Technology

What HNAC Technology does

HNAC Technology Co., Ltd. (300490.SZ), founded in 1993 and headquartered in Changsha, Hunan, is a publicly listed provider of smart energy equipment and engineering services operating across hydropower, new energy/energy storage, lithium battery manufacturing equipment, water treatment, and industrial automation. The company's technology foundation is a multi-energy IoT (多能物联) platform, on top of which it has built proprietary software including the cross-platform HZ3000 SCADA system, the HZN-GGLM Gonggong multimodal large model for water/hydropower O&M (national algorithm registration), the DTW digital twin platform for water conservancy, and the HZN-BHM battery storage health management system. Hardware products span HZ-PCS power conversion systems (up to 98.5% efficiency), HZ-CES integrated storage cabinets, lithium battery formation/grading automation lines via subsidiary Jingshi Electromechanical (which supplies CATL), and Kanpur/CANPURE membrane products (UF, EDI, MBR).

The company monetizes across five revenue streams: equipment manufacturing and sales (one-time hardware), EPC turnkey projects (substations, PV plants, wind farms, water treatment plants, microgrids), intelligent O&M services via subsidiary Huazi Yunwei (covering 320+ hydropower stations, 180+ pump/gate stations, 30+ new energy stations), charging station operations via Huazi Energy Service across Hunan, and bundled system integration/software subscriptions. Go-to-market is enterprise-direct field sales through 14 subsidiaries plus an international arm (Huazi International, Hong Kong) covering 100+ countries, supplemented by participation in industry exhibitions (China-Africa Economic Expo, ESIE, Global Energy Interconnection Conference). Pricing is opaque — all transactions are negotiated via a central business hotline with multi-year B2B contracts. The group has ~2,000 employees across Shenzhen (AI/supercomputing R&D), Wuhan (Jingshi lithium battery manufacturing, ~5 billion RMB annual capacity), Ningxiang (Kanpur membrane manufacturing, ~10 million sqm/year fiber capacity), Beijing (Grant environmental engineering), and Hong Kong.

HNAC has assembled an extensive institutional moat: UNIDO ICSHP control equipment demonstration base, National Manufacturing Single Champion Enterprise, National Technology Innovation Demonstration Enterprise, National Green Factory, 100+ national invention patents, 50+ industry standards co-authored, and a 2010 Second Prize National Science and Technology Progress Award. Customer logos span Chinese central SOEs (China Mobile, China State Construction, SANY, China Energy Engineering Group), African sovereigns (CAR Boali 2 hydropower, Zambia Kasanjiku), and industrial majors (Chenming Paper, Lihua Group, Changsha Metro, Shanghai-Kunming HSR). Capital base was strengthened by 670M RMB convertibles (2021) and 910M RMB equity raise (2023), with proceeds directed primarily at energy storage expansion.
