Dalian Sanhui Thermal Power Co., Ltd. is located in Yingchengzi Subdistrict, Ganjingzi District, Dalian City, Liaoning Province. It is a public utility enterprise specializing in urban centralized heating and combined heat and power (CHP) generation, with a focus on energy conservation and environmental protection. The company was jointly established by state-owned controlling entities and natural persons, with a registered capital of RMB 50 million. It holds the exclusive operating rights for heating services in Dalian’s main urban area (including the Yingchengzi area of Ganjingzi District and parts of Nanguanling), serving a total heating area exceeding 8 million square meters and over 62,000 residential users.  

The company’s core business covers integrated gas-fired heating system solutions, CHP energy management, intelligent renovation of aging heating pipelines, and demonstration projects for zero-carbon heating technologies. Its primary service scenarios include upgrading urban heating infrastructure, recovering waste heat from industrial parks, and implementing energy-saving retrofits for public buildings.  

Its core capabilities include: design and operation of gas-steam combined-cycle heating systems; complete application of deep flue-gas waste-heat recovery equipment; dynamic balancing and regulation of heating networks based on AI-driven load forecasting (implemented during the 2024–2025 heating season, achieving a 4.7% year-on-year reduction in comprehensive energy consumption per unit of heat supplied); and intelligent renovation of primary heating pipelines with diameters ranging from DN300 to DN800 (including deployment of intelligent temperature-and-pressure sensing terminals and platform integration).  

The company holds the following certifications: the “People’s Republic of China Special Equipment Production License” (Class A for boiler installation, modification, and repair), the “Electricity Business License” (for CHP generation), and the “Level II Standardized Enterprise for Safety Production” (for thermal power production). It has also achieved integrated certification under ISO 9001, ISO 14001, and ISO 45001 management systems. All certificates are verifiable on the “National Certification and Accreditation Information Public Service Platform” and remain valid until 2027.  

Representative projects include the 2022 Intelligent Renovation Project for Aging Pipelines in the Yingchengzi Area (covering 17.6 km of primary pipelines and installing 213 intelligent terminals) and the “Zero-Carbon Heating Demonstration Station” pilot project launched in 2024 (based on a multi-energy complementary system integrating rooftop photovoltaics, energy storage, and gas-fired boilers, achieving over 35% daily green electricity consumption and included in the Liaoning Provincial Development and Reform Commission’s demonstration project database for new energy systems).  

Public records indicate no overseas direct investment, international engineering contracting activities, or overseas subsidiary operations by the company, nor any overseas certification records. Its primary cooperation models include domestic EPC general contracting, technology licensing coupled with localized engineering implementation, and industry-university-research collaborative R&D—for example, low-nitrogen combustion technology collaboration with the Dalian Institute of Chemical Physics, Chinese Academy of Sciences, and deployment of a heating AIoT platform with Huawei Digital Power.
