Japan's Federation of Electric Power Companies (FEPC) has called for a clarification of the country's nuclear power policy, to ensure stable electricity supply and alignment with its net zero emissions goal.
The call comes as the government reviews its basic energy policy, which was formulated in 2021 and calls for the reduction of dependence on nuclear reactors as much as possible. But Japan's guidelines for green transformation, which was agreed in February 2023, states that Japan should make the most of existing nuclear reactors.
Tokyo should clearly state in its new energy policy that it is necessary to not only restart existing nuclear reactors, but also build new reactors, said FEPC chairman Kingo Hayashi on 17 May. Hayashi is also the president of utility Chubu Electric Power. Hayashi emphasised that to utilise reactors, it would be necessary to have discussions regarding financial support, policy measures that would help ensure cost recovery, address back-end issues in the nuclear fuel cycle and conduct a review of nuclear damage compensation law.
Japan's current basic energy policy is targeted for the April 2030-March 2031 fiscal year, when the country's greenhouse gas (GHG) emissions is forecast to fall by 46pc from 2013-14 levels. To achieve this, the power mix in the policy set the nuclear ratio at 20-22pc, as well as 36-38pc from renewables, 41pc from thermal fuels and 1pc from hydrogen and ammonia. Japan typically reviews the country's basic energy policy every three years.
Nuclear, as well as renewables, would be necessary to reduce Japan's GHG emissions, although thermal power units would still play a key role in addressing power shortages. But Japan has faced challenges in restarting the country's reactors following safety concerns after the 2011 Fukushima nuclear disaster, with only 12 reactors currently operational. Japan's nuclear generation in 2023 totalled 77TWh, which accounted for just 9pc of total power output.
Tokyo has made efforts to promote the use of reactors, after the current basic energy policy was introduced in 2021. The trade and industry ministry (Meti) has updated its nuclear policy, by allowing nuclear power operators to continue using reactors beyond their maximum lifespan of 60 years by excluding a safety scrutiny period in the wake of the 2011 Fukushima nuclear disaster. This could advance the discussion on Japan's nuclear stance, especially if the new basic energy policy includes more supportive regulations.
The trade and industry ministry started discussions to review the energy policy on 15 May, aiming to revise it by the end of this fiscal year. It is still unclear what year it is targeting and what ratio will be set for each power source in the new policy. But the deliberation would form a key part of efforts to update the GHG emissions reduction goal, ahead of the submission of the country's new nationally determined contribution in 2025, with a timeframe for implementation until 2035.
