[Japan] Toyota Tsusho and Chubu Electric Power Jointly Launched the V2G (Vehicle to Grid) Aggregator Project in Toyota City, Japan

Toyota Tsusho and Chubu Electric Power jointly launched the V2G (Vehicle to Grid) Aggregator Project on May 30, 2018. The project will demonstrate charging Plug-in Hybrid Vehicles (PHVs/PHEVs) and Electric Vehicles (EVs) and the process for discharging stored electricity to grids. The project will evaluate the V2G control system’s performance and impact on the grids, with the goal of utilizing PHVs/PHEVs/EVs to adjust power supply and demand.

The V2G project is being conducted as part of the Ministry of Economy, Trade and Industry (METI)’s FY2018 Demonstration Project on Virtual Power Plant (VPP) Utilizing Demand Side Energy Resources, an initiative that will invest 4 billion yen to fund various VPP demonstration projects over FY 2018. The initiative will focus on implementing control technologies at VPPs with over 50 MW capacity by 2020, as part of METI’s goals to increase renewable energy usage.[1]

VPP technologies combine renewable energy sources such as photovoltaic power generation and energy storage at locations such as residential areas and factories. The introduction of VPP-based renewable energy is expected to expand in Japan, but one challenge to future adoption is fluctuating power output due to changes in weather conditions, and surplus electric power at peak energy production. V2G is a VPP technology that utilizes PHVs/PHEVs/EVs’ in-vehicle battery to manage the fluctuations in output by adjusting the amount and the timing of power supplies.[2]

The V2G project will test the V2G control system, which utilizes multiple in-vehicle storage batteries to control its electricity charges and discharges, in order to verify the feasibility of load balancing through V2G and discharging stored excess renewable energy supplies to the grid when demand is higher. The system will be placed in parking facilities in Toyota City, Aichi Prefecture. The project will use the V2G technology for high frequency regulation developed by the U.S.-based Nuvve Corporation. Regulating at high frequencies is difficult as it requires the system to perform within short response times.

[Japan] Ministry of Economy, Trade and Industry (METI) released the outline for Japan’s Strategic Energy Plan

METI’s Advisory Committee for Natural Resources and Energy released the outline for the 5th Strategic Energy Plan on April 27, 2018. The outline reviews Japan’s progress towards its energy outlook by 2030, which was set in the Long-Term Energy Supply and Demand Outlook[1] published in 2015. The outline also considers Japan’s longer-term vision for energy supply and demand by 2050. The Strategic Energy Plan is the national energy policy that sets the vision and strategies to meet Japan’s long-term energy needs, based on the Energy Policy Act of 2002.

The outline acknowledges the progress made to date since Japan’s current Strategic Energy Plan was enacted in 2014 and pledges to further boost the measures currently in place. Japan will continue to rely on nuclear energy as an important zero-emission baseload energy source, however, the country will reduce its dependency on nuclear energy by promoting energy efficiency, renewable energy, and efficient thermal power generation. According to the outline, Japan expects that 44% of its generation mix will be zero-emission sources by 2030, which it will achieve by re-starting nuclear power plants and increasing renewable energy. Japan will advance its energy technologies, such as IoT, AI, and big data, and will integrate multiple business operators and systems, as part of a plan to enhance energy conservation by 2030. The outline sets several long-term goals to achieve by 2050, such as expanding renewable energy, reducing reliance on nuclear energy, combining advanced technologies to develop high efficiency distributed energy systems, and replacing low-efficiency coal-fired power plants with more high-efficiency coal fired power plants, as part of the process to transition Japan into a decarbonized society.[2]
