高储能占比！山东济泰高速交能融合项目正式开工

Core Viewpoint - The Jitai Expressway Energy Integration Project, initiated by China Energy Construction Gezhouba Group, aims to create a high-proportion green power self-sufficient energy system through solar power generation and large-capacity energy storage, marking it as the largest energy storage project in Shandong's operational expressways [1][3]. Group 1 - The Jitai Expressway Energy Integration Project follows the successful implementation of the Zao-Hu Expressway project, showcasing significant demonstration effects in energy integration [3]. - The project features a high bridge-tunnel ratio of 68%, with substantial and concentrated electricity demands for tunnel lighting and ventilation, prompting innovative space utilization for energy integration [3]. - The project will utilize various areas such as toll stations, service area rooftops, and central dividers to efficiently convert these spaces into green energy sites, achieving comprehensive application of solar power facilities [3]. Group 2 - The total planned installed capacity of the project is approximately 3.96 megawatts, with a supporting energy storage system capacity of 2 megawatts/4 megawatt-hours, capable of storing up to 4,000 kilowatt-hours of electricity [5]. - The project is expected to generate over 4.42 million kilowatt-hours annually, meeting about 60% of the electricity demand for the entire route, saving approximately 1,330 tons of standard coal and reducing carbon dioxide emissions by about 22,000 tons per year [5]. - The project adopts a "self-generated and self-used" model with an intelligent microgrid control system, enabling integrated regulation of source, grid, load, and storage [7]. Group 3 - During the day, solar power generation will prioritize energy supply, with surplus electricity stored in the energy storage system for use during nighttime, rainy days, or peak electricity pricing periods, effectively reducing reliance on traditional power grids and lowering electricity costs [7]. - Once completed, the project will serve as a benchmark for low-carbon, efficient, and smart transportation, providing a new model for addressing low-carbon electricity challenges in high bridge-tunnel ratio highways across the country [7].
