Shanghai-based automotive company NIO has announced the completion of what they are calling the world’s first V2G photovoltaic self-consumption system in the Qilian Mountain National Park.
The V2G self-consumption station is operational within Qilian Mountain National Park’s long-term national research base, providing continuous support for ecological patrols and clean, low-carbon energy utilisation within the park.
According to NIO in a press release, the system marks the first global photovoltaic self-consumption system with V2G (vehicle to grid), composed of photovoltaic power stations, bidirectional V2G charging piles and all-electric vehicles.
V2G systems allow EVs to serve as distributed mobile energy units, charging during low-demand periods and supplying power during peak times.
The technology, through the deployment of source-network-storage-load, states NIO, achieves local self-production and self-marketing of green energy and minimises the impact on the external environment.
V2G bidirectional charging piles offer EV charging services; with the reverse discharge function, surplus vehicle-stored energy is supplied back to the grid for nighttime or emergency use within the park.
Photovoltaic power energises the system, with an annual average output of about 690,000kWh, fully covering the EV energy consumption within the park.
Surplus energy can cater to over 50% of other power needs, resulting in an estimated annual carbon reduction of around 55 tonnes.
Clean Parks initiative
NIO and WWF previously collaborated together to support the ecological construction of Northeast China Tiger and Leopard National Park, as well as Giant Panda National Park, and became strategic partners of the Clean Parks ecological co-conservation plan in April 2022.
The V2G announcement marks the commencement of the third phase of the Clean Parks and WWF ecological co-conservation programme.
The self-consumption facilities were established by Clean Parks in collaboration with NIO, Astronergy and One Earth Nature Foundation in Qilian Mountain National Park, China, on the eve of the Second National Park Forum, under the coordination of the Qinghai Forestry and Grassland Bureau and the WWF.
