CHN Energy Zhishen Control Technology Co., Ltd. (abbreviated as CHN Energy Zhishen) is a leading domestic supplier of industrial automation, digitization, and intelligent product technologies and comprehensive solutions. It is a wholly state-owned high-tech enterprise under the control of the CHN Energy Technology & Environment Limited, with participation from the State Grid Electric Power Research Institute (Nari Group). Its predecessor was the Power Plant Automation Institute of the former Ministry of Water Resources and Electric Power, established in 1984. As a national leader and key player in the industrial control field, CHN Energy Zhishen adheres to the principle of secure and independent control in its R&D, achieving full-stack control from hardware, firmware, to software layers, with 100% independent platform software and 100% domestically produced hardware and operating systems. This resolves the "chokepoint" issues in industrial control systems, ensuring the security of critical infrastructure for national energy production. With over 4,500 sets of applications under independent intellectual property rights, it covers fields such as thermal power, hydropower, new energy, nuclear power, coal, and chemicals, spanning an installed capacity of over 350 million kilowatts in the power system. Among these, the fully domestically produced and independently controllable intelligent Distributed Control System (iDCS) has been applied in over 150 sets, making significant contributions to the secure, controllable, and intelligent development of China's energy production. It has repeatedly broken foreign monopolies and filled domestic gaps in high-end industrial control, achieving multiple "China's first" and "world's first" milestones, earning widespread recognition from industry users. In 2022, CHN Energy Zhishen was successively selected as a Beijing Specialized, High-end and Innovation-driven Small and Medium-sized Enterprise, a National Specialized, High-end and Innovation-driven "Small Giant" Enterprise, and a National Intellectual Property Advantage Enterprise. In 2023, it was selected by the State-owned Assets Supervision and Administration Commission of the State Council as a "Science and Technology Reform Enterprise" and a "World-class Professional Leading Demonstration Enterprise."
