The ruling Liberal Democratic Party is pushing a policy of heightening Japan’s dependence on nuclear energy but has buried this stance under a calculation trick.
An LDP research commission on energy issues on April 2 called on the central government to ensure that base-load electricity sources--nuclear energy, coal-fired thermal plants, hydroelectric and geothermal plants--account for about 60 percent of Japan’s energy needs in 2030.
The proposal does not mention any specific ratio for nuclear energy. But considering the difficulties in increasing the supply from the other base-load electricity sources, the dependence on nuclear power would have to rise to about 20 percent.
The proposal is expected to be presented to Prime Minister Shinzo Abe as early as next week as the formal recommendation of the LDP. The central government wants to decide on the energy mix for Japan in 2030 and beyond by June.
The government’s designation of the base-load electricity sources means their costs for power generation are comparatively low and electricity can be produced around the clock.
In fiscal 2013, Japan depended on base-load electricity sources for about 40 percent of its power: 1 percent for nuclear energy; 30 percent for coal-fired thermal plants; and a combined 9 percent for hydroelectric and geothermal plants.
However, coal-fired thermal plants emit huge volumes of carbon dioxide that go against measures to deal with global warming, so raising the ratio of energy from such plants would be difficult. Increasing dependence on hydroelectric plants would also be tough because huge dams would have to be planned.
Geothermal plant projects are also time-consuming because of the need for environmental assessment studies.
If the government cannot raise the ratio for these three base-load electricity sources, the nation’s dependence on nuclear power would have to rise to 20 percent to meet the 60-percent goal in the proposal.
The LDP panel’s proposal said, “Energy policy must serve to strengthen Abenomics.”
It pointed out that electricity rates increased after nuclear power plants went offline following the Fukushima nuclear crisis triggered by the 2011 Great East Japan Earthquake and tsunami.
But to achieve that level of dependence on nuclear energy, nuclear plants would have to be operated beyond the current 40-year operating life set by the government or the government would have to approve the reconstruction or new construction of nuclear plants.
An experts’ panel under the Ministry of Economy, Trade and Industry is discussing the energy mix. At the end of March, the ministry recommended that base-load electricity sources account for about 60 percent of total energy supply, about the same level as found in Western nations.
The LDP panel’s proposal also referred to the fact that many Western nations depend for at least 60 percent of their energy needs on base-load electricity sources.
