TBEA Sunoasis Design Institute recently completed the planning scheme of the first typical demonstration project for the full implementation of “PV + Highway” in China. The project is located in a service area along a highway, with a total planned capacity of 3.5 MW. It is designed with a self-generating and self-consumption mode of operation that can satisfy the daily demand for electricity of the infrastructures in the service area. Once completed, it can generate 4,200 MWh of electricity per year, which is equivalent to an annual saving of 1,377.6 t of standard coal (based on average consumption of standard coal of 320 g / kWh) compared to the thermal power of the same capacity and consequently can reduce emissions of various air pollutants per year, including approximately 126 t of sulfur dioxide (SO2), 4187.4 t of carbon dioxide (CO2) and 63 t of nitrogen oxides ( NOx).
What is “PV + Highway”?
“PV + Highway” aims to integrate photovoltaic power generation technology with the highway system, to be used on roads, ditches, ramps, isolation areas and other spaces in the highway system, as well as the space of building roofs, parking sheds, walls and other facilities in the service area for the arrangement and installation of the photovoltaic power generation system. The clean energy generated will be applied to lighting and ventilation installations for bridges and tunnels, electrical installations in service areas and other highway systems or exit to the grid system.
As you all know, in order to achieve the “maximum carbon dioxide emissions” and “carbon neutrality” targets, the photovoltaic industry has brought new opportunities and development challenges. In 2020, China’s highway mileageit has exceeded 150,000 kilometers. With the advent of the era of “5G + intelligent transportation” and the innovation of electric vehicles, smart charging batteries, autonomous driving technology in the transportation sector and the annual energy consumption of the highway system will increase significantly, together with the original lighting and ventilation installations of the bridges and tunnels, and the electrical installations in the service areas; In addition, photovoltaic power generation will have enough space for consumption. Typical demonstration, included in power generation and environmental protection.
The project is a good solution for the single power grid power supply structure in remote areas of the highway system, and it will be the best way to supplement the power source in local service areas. At the same time, in addition to meeting the demand for electricity in the service area, the combination of the area’s attributes as transportation infrastructure also maximizes the aesthetics of the photovoltaic project. In addition, in combination with the owner’s need to create the “PV + transportation” demonstration project along the highways in China, the project design plan consists of using the current national and international advanced photovoltaic power generation design concept, which integrates PV technology on roads, photovoltaic modular tile sidewalks, PV system on slopes, photovoltaic acoustic barriers, photovoltaic roofs, photovoltaic central barrier and other forms of application only. Upon completion, the project will become one of the most advanced and perfect “PV + transportation” projects on the entire highway and even the highway system in China., which has advanced demonstration meaning and will play a positive role in promoting the combination of photovoltaic power generation technology and transportation infrastructure. TBEA Sunoasis drives business innovation with advanced technology and has developed a digital design platform that integrates digital wind resource assessment, digital engineering design and 3D transmission line design, which can realize the design management of the entire cycle life span of wind farms, generate 3D digital design solutions for wind and photovoltaic energy that meet national and international design standards and transfer standards, as well as 3D design solutions for 35 kV collector lines from national wind farms and transmission lines of 220 kV or less from the national grid. Likewise, has achieved a cumulative design capacity of more than 16 GW for projects in the new energy industry.
