Three challenges in energy policies

  • To establish imminent-, medium- and longer-tem energy strategies that reduce uncertainty for the private sector and increase confidence among a public.

  • To formulate a flexible and diverse energy utilization

    • Nuclear power (a role for baseload power)

    • Fossil fuels

    • Renewable energy

  • To use technological strength to contribute to the international community.

    • Climate change

    • Nuclear safety

    • Saving fossil fuels

  • Three Challenges in Energy Policies

    Restart of nuclear power plants

    • No-Nuclear scenario means;

      • Adverse effects on Japanese economy

      • Relinquishment of Japan’s critical roles in the establishment of global standards on nuclear safety, security, and nonproliferation

    • Actions towards Restart

      • Four Steps

        • Stress tests by nuclear operators

        • Approvals of Nuclear and Industrial Safety Agency(NISA)

        • Consents of Nuclear Safety Commission.

        • Approvals of local governments

      • Recent statements of PM Noda and Industry Minister Edano

    F or the successful utilization of renewable energy

    • New Feed-in-Tariff as a booster (scheduled to start this summer)

      • Entails utilities’ obligation to purchase all electricity generated by renewable energy sources, with no limitation, at prices to be fixed by the government.

      • Surge in investments (ex. mega-solar, wind).

        • Companies (Japanese, U.S., Canadian) and governments (central, local)

    • The success depends on various factors

      • The criteria for approval of specified suppliers

      • The requirements for interconnection (costs and sharing responsibilities in stable supply)

      • The capacity of the grid etc.

    For the Successful Utilization of Renewable Energy

    Energy sector resiliency

    • Current structures of the Japan’s utility sector

      • 10 utilities with a vertically integrated business model

      • The difference in frequency between eastern (50-hertz) and western Japan (60-hertz)

    • Needs to discuss new structures for greater efficiency and flexibility that would fully accommodate power generation from diversified sources and players

      • Ownership and participation in generation, transmission, and distribution business

      • Responsibilities for maintaining stable electricity supply

      • Costs of business developments etc.

    Energy Sector Resiliency


    • Energy is the “blood” of national livelihood and corporate activities. Energy policy is one of the most important pillars of national strategy.

    • Three factors to shape future of Japan’s energy

      • Technology

      • Markets

      • Competition
