The Japanese Energy and climate policy has undergone important transformation since the 2011 Great Earthquake and the shutdown of nuclear power plants following the Fukushima accident. A set of measures has been introduced for promoting renewable energy development in the power mix, targeting a share of 22-24% share in 2030. These measures resulted in a rapid growth of solar PV (34 GW operating in 2015 as a total and further 68 GW registered capacities). However, the country is still facing several challenges, which could potentially limit further renewable energy development and endanger Japanese climate commitment.

Against this background,  Agora Energiewende initiated in 2016 a partnership with the Japanese Renewable Energy Institute (former Japanese Renewable Energy Foundation JREF), with the goal to transfer expertise and deepen information exchanges about the ongoing energy transition in Germany and Japan. Furthermore, Patrick Graichen is Member of the German-Japanese Energy Transition Council (GJTEC), a high-level-dialogue and research platform, gathering German and Japanese experts on energy issues.

    Renewable pathways to climate-neutral Japan

    Japan has pledged climate-neutrality by 2050. Now, on the tenth anniversary of the Fukushima accident, a new report by Renewable Energy Institute (REI), Agora Energiewende, and LUT University finds that a zero-carbon energy supply based solely on renewables would be affordable in Japan.

    Minimizing the cost of integrating solar and wind in Japan

    While estimates have been made for integration costs, they are very country-specific. Relatively little work has been done for Japan, unfortunately. For instance, no analysis has been found for transmission grid costs in Japan. A new study by Agora Energiewende entitled “Minimizing the cost of integrating wind and solar power in Japan” aims to fill such gaps.

    Request for proposal - Renewable-based decarbonization pathways for Japan

    Agora Energiewende and the Renewable Energy Institute Japan (REI) are launching a new project entitled “A 2050 renewable-based decarbonization pathway for Japan - study on the role of renewable-based electrification in supplying power, transport, heating and cooling demands in Japan”. We are searching for consultants to support us with this project.


    Japan’s Grid Can Handle More Wind and Solar Power than Currently Envisioned by Its Government

    Although Japan has experienced a solar boom in the past five years, ongoing concerns about the stability of its power grid have slowed the expansion of wind and solar, leaving the country with renewable energy targets below the global average. But an independent study has shown that technical solutions exist that can help Japan meet the challenges of transitioning to clean energy.

    Integration costs for renewable energy: controversial, but likely low

    High shares of wind and solar power transform the entire power system and can lead to additional costs aside from building the power plants themselves. A new background paper examines these dynamics and concludes that not only the direct integration costs are low, but also the controversial indirect costs – as long as the power system becomes considerably more flexible.
