The economics of these distributed resources is
dependent upon LNG prices and the electric rate structure,
which currently favors electrical usage for heating systems.

nearly double, to 70.2 million toe in 2035 from 39.1 million toe
in 2011. The report assesses the effect of electricity prices on
electrical demand.
The Sixth BPE in South Korea calls for the aggressive
construction of coal-fired power plants, which will reduce
the role of LNG in power generation. The economic and reliability effects of the RCES business model must therefore be
evaluated. The main problems confronting the RCES model
in South Korea are poor economics, exposure to high LNG
prices, and the uncertainties of the electricity market system.
South Korea does not have the capacity to produce natural gas, and the country imports LNG from Qatar, Oman,
and Indonesia, favorable locations that minimize the LNG
transportation price. South Korea remains an energy-isolated
country that has no interconnecting pipelines with neighboring countries. Discussions have been conducted that have considered interconnecting an LNG pipeline with Russia, but this
plan deemed unacceptable because of national energy security
issues, especially with respect to North Korea.
The proposed ASG aims to interconnect countries in
northeast Asia with electricity generation areas in the Gobi
Desert. Such a "supergrid" would bring technical and political challenges because of its large geographical footprint.
The project remains under negotiation as the economic
opportunities are weighed against the political challenges.
An inadequate SPR rate in South Korea during recent
summer and winter periods has resulted in frequency control and stability problems in the power system. The problem will be solved with the addition of transmission and
generation facilities. Although the construction of new
transmission lines on exiting rights-of-way is not possible, a phased approach of undersea HVdc projects that
surround the main peninsula of South Korea appears to be
viable solution. Hydro, pumped storage generators, and
LNG generation will provide a more important role in frequency regulation. The addition of distributed small-scale
gas cogeneration systems will improve system performance
and will be fully considered under the electricity market
environment in South Korea. The economics of these distributed resources is dependent upon LNG prices and the
electric rate structure, which currently favors electrical
usage for heating systems.
