Chang Sha Wan Bao·2025-12-30 00:09Core Viewpoint - The Wancheng District is implementing a ten-year road lighting energy cost management project to promote smart city governance, focusing on energy efficiency, safety, and intelligent management, without requiring upfront government investment [3][4][5]. Group 1: Project Overview - The project involves the management of 25,321 streetlights, with 41,457 lamps, primarily high-pressure sodium lamps, and only about 7,000 LED lamps [3]. - The district's budget for public streetlight electricity and maintenance in 2024 is projected to be 44.84 million yuan, with approximately 35.62 million yuan for electricity and 9.22 million yuan for maintenance [3]. Group 2: Challenges Addressed - Existing issues include aging infrastructure, inadequate illumination, reliance on manual inspections, and high energy consumption from traditional lighting systems [4]. - The project aims to address these challenges by implementing a systematic upgrade of public lighting facilities to enhance operational efficiency and safety [4]. Group 3: Implementation Details - The project is being executed by a consortium including China Tower Group, Hefei Daming Zhiliang Technology Co., and Liard (Hunan) Light Environment Cultural Development Co., using an energy cost management and smart service model [5]. - The upgrade will replace high-pressure sodium and old LED lamps with high-efficiency, low-power LED fixtures, and will include the installation of smart control systems for individual lamps [5][6]. Group 4: Energy Savings and Environmental Impact - The new LED lighting is expected to achieve over 50% energy savings, translating to an annual reduction of over 25 million kWh, equivalent to saving 8,000 tons of standard coal and reducing CO2 emissions by approximately 20,000 tons [6]. - The energy cost management model is projected to save about 13 million yuan annually, totaling 1.3 billion yuan over ten years [7]. Group 5: Smart Management Features - The smart platform allows for precise fault detection and rapid repairs, improving operational efficiency and maintaining a light rate of over 98% [8]. - The system will also enhance public safety by integrating video monitoring and other smart applications, transforming streetlights into multifunctional urban nodes [8][9]. Group 6: Future Goals - By 2026, Wancheng aims to establish an integrated system of smart lighting and urban governance, enhancing the overall quality of life and contributing to the district's "dual carbon" goals [9].
