Smart Grid Demonstration Project on Jeju Island, South Korea

Smart Grid Demonstration Project on Jeju Island, South Korea

South Korea has positioned smart grids as a strategic national industry, and started a smart grid demonstration project on Jeju Island in 2009. In 2010 the country announced its National Smart Grid Roadmap, and then in 2011 it enacted the world’s first law related to support for smart grids.

Smart grids are electricity grids that achieve a highly efficient and highly reliable power supply by utilizing information technology for power networks from the power plant to the supply grid and to the homes that consume the power. They also hold promise as a means for handling the fluctuations in output for wind power and solar power and making the mass adoption of renewable energies possible.

Jeju Island, which is located at the southernmost tip of South Korea, is in the vicinity of the Tsushima Current, a warm water current. As such, it has a warm climate and is well-known as a tourist destination. What is more, within South Korea it is an ideal spot for wind power and solar power generation. Fig. 1 shows a wind speed distribution map for South Korea.

The demonstration project on Jeju Island was carried out by being divided up into a first stage for installing the system that lasted from December 2009 until May 2011, and an integrated operating period from June 2011 until May 2013. It was divided up into a number of themes, including Smart Places, Smart Transportation, and Smart Renewables, and was carried out with the participation of a large number of companies. Table 1 shows examples from the smart grid demonstration project on Jeju Island.

While it was promoting this demonstration project, in 2012 Jeju Province announced its Carbon Free Island Jeju by 2030 plan, which aims to achieve a carbon free island that generates power solely through wind power and other renewable energies and that only uses electric vehicles. (May 2014)
