KEPCO Completes 72 Transmission and Substation Construction Projects Last Year, Expects KRW 850 Billion Savings in Power Purchase Costs

Bukdangjin~Sintangjeong Transmission Line Completed After 21 Years
KEPCO Expects Annual Power Purchase Cost Savings of 850 Billion KRW
Completion of Major Power Grid Projects Including Asia's Largest ESS and Wando~East Jeju HVDC
Enhanced Power System Stability and Support for Next-Generation Display Investments in Cheonan and Asan

Korea Electric Power Corporation (KEPCO) announced on the 22nd that it completed a total of 72 transmission and substation construction projects last year, including the construction of the Bukdangjin~Sintangjeong transmission line.

The projects completed by KEPCO include the construction of the 345kV Bukdangjin~Sintangjeong transmission line, the establishment of Asia's largest (978MW) system stabilization ESS (Energy Storage System), and the construction of the Wando~East Jeju HVDC (High Voltage Direct Current) system. KEPCO expects that completing these power grid construction projects will reduce annual power purchase costs by approximately 850 billion KRW, effectively eliminating a 1.6 KRW per kWh electricity rate increase factor.

Among these, the Bukdangjin~Sintangjeong transmission line, completed in November last year, took 21 years to build, marking the longest construction period in South Korea. KEPCO anticipates that resolving generation constraints in the West Coast region will save about 350 billion KRW annually in power purchase costs. Additionally, next-generation display investments in the Cheonan and Asan areas, designated as national advanced strategic industry specialized complexes, are expected to gain momentum.

Furthermore, with the completion of the system stabilization ESS construction project, the frequency stability of the power system is expected to improve. In particular, resolving generation constraints on the East and West coasts is projected to save 500 billion KRW annually in power purchase costs.

Moreover, the completion of the Wando~East Jeju HVDC construction project is contributing to expanding the power supply capacity in the Jeju region and enhancing the accommodation capacity for renewable energy generation.

A KEPCO official stated, "Going forward, KEPCO will continue to promote innovations in laws and systems that meet public expectations to enhance residents' acceptance of power facility construction, and will do its utmost to ensure the timely construction of the national power grid."
