Nuuve and Japan’s Chubu Electric Power Miraiz Company are strengthening an existing commercial agreement with the addition of three stationary, vehicle-to-grid capable lithium-ion batteries in two new locations in Japan. This aims to enhance grid service capabilities. 

The press release stated that the batteries are expected to serve both as a power source and to provide a variety of balancing and demand response services to the grid. 

Chubu and Toyota Tsusho Corporation partnered with Nuvve earlier this year, in order to receive approval from the Japanese transmission system operator (TSO).  

Nuvve has over a decade of experience working with multiple TSOs worldwide to qualify aggregated electric vehicles and stationary batteries to provide and get paid for bi-directional grid services, said the company’s press release.  

In the case of this Japan-based deployment, TSO qualification allows the companies to bid available capacity and energy from stationary batteries into the Japanese market to provide flexibility and demand response services, generating revenues in return.  These batteries will be added to two existing sites in Chita and Komaki for participation in Japan’s energy market. 

This latest phase of the program connects Nuvve’s Grid Integrated Vehicle platform to two industrial stationary storage batteries in Kyoto (1.425 MWh /500kW and 0.178 MWh/125kW) and one in Toki (0.534 MWh/250kW), for a combined total of 2.137 MWh/875kW capacity. 

Japan has been chosen due to its unique commercial market. The country is divided into two main regional electric systems.  

In 2021, the industry ministry and energy operators announced plans to double its electricity grid capacity to 23 million kilowatts (kW) as a way to help reduce greenhouse gas emissions to net-zero by 2050. Using stationary battery storage and stacking it with potential capacity and services provided by EVs using V2G can help Japan reach this goal.
