The facility features 34 inverters and 340 batteries with a total storage capacity of 100 megawatts, aimed at ensuring a stable energy supply for local residents by addressing supply gaps during fluctuating demand.

This expansion is expected to enhance their operational expertise in ESS management and electricity trading, which will be crucial as Korea prepares to launch its own electricity market. SK Gas Representative Director Yoon Byung-suk emphasized the growing importance of ESS projects in managing renewable energy volatility, highlighting SK's commitment to exploring eco-friendly energy sectors, including ESS and hydrogen energy.
