The government will complete the construction of the first-phase power supply facilities for the Honam semiconductor industrial complex by 2029. The government will provide financial support for part of the construction costs borne by the private sector. For the Yongin semiconductor industrial complex, three LNG (liquefied natural gas) power plants with a capacity of 1GW (gigawatt) each will be built to ensure smooth initial power supply.
The Ministry of Climate, Energy and Environment announced on the 12th that it signed an agreement with Gwangju Metropolitan City in Jeollanam-do, Samsung Electronics, SK Hynix, and KEPCO to ensure timely power supply for the Honam and Yongin semiconductor mega-projects.
The institutional investors participating in the agreement have decided to pool their respective capabilities as much as possible to ensure timely power supply to the industrial complex. Gwangju Metropolitan City, which participated in the Honam semiconductor industrial complex power supply agreement, plans to actively cooperate to ensure that necessary permits and approvals for constructing power supply facilities are obtained promptly.
For the Honam industrial complex, where power demand exceeding 6GW is expected, the government plans to complete the construction of initial power supply facilities with a capacity of 3GW as the first phase by 2029 to enable early factory operations. Subsequently, through the second-phase additional facility construction, more than 6GW of cumulative power will be supplied to the Honam industrial complex.
For the Honam industrial complex power supply routes, the first phase will involve constructing a line branching from the Sinjangseong-Sin Gwangju line and connecting it to the industrial complex. The second-phase route is planned to be finalized through detailed technical reviews and consultations with companies and relevant institutional investors. For substations, one substation will be built within the industrial complex in the first phase, and an additional substation will be added in the second phase.
The costs for the first-phase power supply facilities will be shared between the public and private sectors according to their usage proportions. Some of the private sector's contribution will be supported through national finances following consultations with relevant ministries under the Semiconductor Special Act.
For the Yongin National Industrial Complex and General Industrial Complex, power demand exceeding 14GW is expected by 2041.
In the case of the Yongin National Industrial Complex where Samsung Electronics' factories will be built, a total of six factories will receive power in stages by 2041. As the first phase, until 2032, the complex plans to meet initial demand by utilizing aging coal replacement volumes for short-distance lines near the industrial complex and three LNG power plants with a capacity of 1GW each within the complex.
As the second phase, additional demand will be addressed by increasing the capacity of existing lines by 2035. Ultimately, power supply routes from the eastern coast and central regions will be constructed, and details will be finalized through technical reviews and consultations with companies and relevant institutional investors.
For the Yongin General Industrial Complex where SK Hynix's factories will be built, initial power will be supplied via transmission lines connecting the newly completed Sinanseong substation last month to the Dong-Yongin substation as the first phase. As the second phase, lines near the industrial complex and supply routes from the eastern coast will be constructed ahead of schedule in 2031 and 2032.
Kim Seong-hwan Gi Hu-bu (Minister) stated, "The key to the success or failure of semiconductor mega-projects is timely power supply," adding, "The government, companies, and local communities will work as one team to drastically shorten administrative procedures and dedicate all efforts to ensure that power is supplied on time in line with the construction of new industrial complexes."
