0. Bottom line first

The core is a manufacturing platform combining RE100 power, IRA/CBAM response, Korea-China precursor JVs, and tax plus cash incentives. Success depends on completing 7GW of renewables and proving direct-PPA price competitiveness.

1. Location logic

Electrification and carbon neutrality shift site selection from labor and logistics toward RE100, tariff-free market access, IRA/CBAM response, and large-scale decarbonized power.

Official fact: The source says Saemangeum is Korea’s first smart-green national pilot industrial complex and a specialized battery complex.

  • Corporate and income tax relief is structured as 100% for three years and 50% for the next two years.
  • The cap combines 50% of cumulative investment and an amount tied to regular employee count.
  • The local-investment promotion subsidy cap rose from KRW 20bn to KRW 30bn per company.

3. Companies and interpretation

JV

LG Chem-Huayou Cobalt

Presented as a case combining U.S. market access and raw-material security.

JV

SK On-GEM

Mentioned as an axis of precursor and battery-material supply-chain restructuring.

Domestic

LS Group and others

The source says related alliances are committing more than KRW 15.5tn to Saemangeum.

Interpretation: Saemangeum combines Chinese raw-material/refining capability with Korea’s FTA status to address IRA value-add requirements.
