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
