As of 2001, there were four power plants on Jeju, with more under planning and construction. The most notable of these are the gas-fired generators of Jeju Thermal Power Plant, located in Jeju City. The present-day generators of this plant were constructed from 1982 onwards, replacing earlier structures that dated from 1968. As elsewhere in Korea, the power supply is overseen by the Korea Electric Power Corporation, or KEPCO. In February 2012, the governor of the state of Hawaii (USA), Neil Abercrombie, and the director of the Electricity Market and Smart Grid Division at the Korea Ministry of Knowledge Economy, Choi Kyu-Chong, signed a letter of intent to share information about Smart Grid technology. The Jeju Smart Grid was initially installed in 6,000 homes in Gujwa-eup and is being expanded. South Korea is using the pilot program of the Smart Grid on Jejudo as the testing ground in order to implement a nationwide Smart Grid by 2030. Transportation The island is served by Jeju International Airport in Jeju City. The Seoul–Jeju City air route is by a significant margin the world's busiest, with around 13,400,000 passengers flown between the two cities in 2017. Other cities
