On October 29, the Zaozhuang-Heze Expressway Transportation-Energy Integration (Source-Grid-Load-Storage Integration) Demonstration Project, led by GEDI under the EPC contracting, had a cumulative power generation of over 100 million kWh.
As China's first demonstration project for the transportation-energy integration in the entire expressway area, the project has been selected as a typical case of green and low-carbon energy transformation by the National Energy Administration, approved as China's first innovation demonstration base for transportation-energy integration and a national expressway science popularization education base, and selected as a Global Sustainable Transport Best Practice Case. Moreover, the project has been presented at the Release of the Global Sustainable Transport Best Practices Compilation held at the United Nations headquarters as a key promotion case of the Chinese delegation.
The project is situated along the Zaozhuang-Heze section of the Rizhao (Lanshan) to Heze Expressway in Shandong Province, spanning approximately 178 kilometers. It utilizes idle spaces such as roadside slopes, ramp circles, service areas, and toll stations along the expressway to install distributed photovoltaic power generation facilities and supporting energy storage facilities. It creates a full-chain interactive "source-grid-load-storage" system that continuously supplies green and clean energy for infrastructure and vehicles. Leveraging the multi-scenario intelligent energy control system independently developed by GEDI, known as the "Harmony" system, the project matches expressway power loads with photovoltaic generation in real time. It accurately achieves dynamic balance through the concept of "self-use priority and external supply of surplus electricity", and forms an energy supply model combining "transportation power self-use + regional complementarity". Currently, the first and second phases of the 78 MW project are put into operation, generating a total of 104 million kWh to date. This is equivalent to saving approximately 31,800 tons of standard coal and reducing carbon dioxide emissions by nearly 51,300 tons, delivering a dual benefit of economic gain and environmental protection.
