A Study on Quantitative Effects Analysis Due to Direct Import of LNG

This study quantitatively evaluates the impact of increasing direct LNG imports on Korea’s electricity market using machine learning, PLEXOS simulation, and statistical analysis. The results consistently showed that direct LNG imports effectively reduce system marginal prices and electricity purchase costs for KEPCO, confirming their positive market influence. Policy recommendations include easing regulatory constraints and enhancing public-private collaboration to ensure energy security, supply stability, and market flexibility.
