The Basic Energy Plan is a policy document formulated by the Government of Japan under the Basic Act on Energy Policy, which entered into force in June 2002. The plan presents the basic principles of Japan’s energy policy, namely, “safety,” “energy security,” “improving economic efficiency,” and “environment suitability,” and shows the basic direction of the energy policy. Since 2003, a new strategic energy plan has been developed every 3-4 years.
METI's 4th Strategic Energy Plan (Basic Energy Plan), released in 2014 calls for nuclear energy to account for 20%-22% of power generation by 2030, with 22%-24% coming from renewable energy sources, while coal's share will be reduced to 26%, LNG's to 27% and oil's to just 3%.
The report, by the Ministry of Economy, Trade and Industry (METI), says that total energy demand in Japan will increase from 940 TWh in 2013 to 980.8 TWh in 2030.
