rental fees are expected to decrease by one tenth. These new policies are perceived as helping expand the use of renewable energy and should be more aggressively pushed forward. More policies are expected to follow, in line with the Moon government’s intention to promote the development of renewable energy. 5. Isolated grid system and the possibility of stable power supply Energy is supplied to almost 100 per cent of the population. The expansion of power supply facilities with grid infrastructure occurred in the Republic of Korea the fastest out of all the OECD countries. With the lowest electricity prices, electricity service can be easily accessed in comparison with other countries. The prices of electricity for industry are also much cheaper than in other OECD countries, which helps keep its consumption continuously growing. The Republic of Korea is a peninsula country but seems more an isolated island due to divisions with its northern neighbour, which causes difficulties in connecting electricity grids, oil pipelines and gas pipelines with other countries. This makes energy security an important issue. For example, because natural gas needs to become imported by ship, its price in the Republic of Korea is relatively more expensive than in countries that import through a pipeline. There are gas exchange markets, such as Singapore SGX, Shanghai SHPGX and Japan JOE. In China, Pipeline Natural Gas is linked and has a large market size. Because the Republic of Korea has a rigid trading system, Pipeline Natural Gas is not linked and a gas exchange has not yet opened. With the global gas market transformed into a buyer s’ market, rigid gas contract conditions are improving. Korea-China-Japan cooperation is in progress to eliminate the obstacles to free gas trading, such as destination clauses to resolve the three countries’ Liquified Natural Gas issues in North-East Asia. Since a summit of the Republic of Korea, China and Japan in 2015, the government has been strengthening cooperation on gas issues. In 2017, a memorandum of understanding for the abolition of the destination clause between the representative companies of the three countries will be pursued. With the Republic of Korea importing only liquified natural gas, it is a valuable option to introduce Russian gas into another transport system called Pipeline Natural Gas. Therefore, the Park government planned to resume the discussion of a gas pipeline connecting the Republic of Korea, the Democratic People’s Republic(DPR) of Korea and Russia. Under the premise that the inter-Korean relations will be improved in the near future, it will be used as a bargaining card in China in the short term to induce DPR of Korea to cooperate with the South-North Korean gas pipeline and to use it to enhance negotiating power in Russia. Jungeui Son, President of Soft Bank Group in Japan, proposed an“ Asia Super G rid” that produces electricity from wind and solar energy in the Mongolian deserts and transmits electricity to Japan and Korea. If the super grid project is pushed forward, it may cause a change in energy source from fossil fuel or nuclear power to renewable energy. However, it may also cause problems in terms of whether dependency on energy imports can be avoided and the stability of energy supply can be secured. If the Republic of Korea can get out of its energy island without grid connection with other countries, an alternative to nuclear power can be found. If the rich water resources in the Russian Far East and the wind power generation in the Inner Mongolia region are supplied to 21
