Korea opens 1,180 MW battery auction to balance power grid
The 7.08 GWh central tender introduces a 25-year contract option in Jeju and tests local cell supply chains at Samsung SDI, SK On and LG Energy Solution.
The Korea Power Exchange opened formal bid registrations on Sept. 30, 2026, for a record 1,180-megawatt central energy storage auction, pitting South Korea's top three battery makers against each other.
The Ministry of Climate, Energy and Environment initiated the tender to curb transmission bottlenecks and absorb rising volumes of variable renewable power. Regulators designed the competitive market to stabilize regional grids before nuclear and solar generation exceeds line capacity.
