Korea's new battery complex at Gwangyang Bay starts with POSCO affiliates' existing plans

The 12.99 trillion won is company spending that the government says it will support through 2042. It covers all three complexes named in this round: robotics in Gumi and Pohang, defense in Changwon, batteries in Gwangyang, Yeosu and Suncheon ^[10][11]. Over the roughly 16 years to 2042, that averages about 810 billion won a year for the whole round ^[15]. If the three complexes split it evenly, the battery complex would get about 4.33 trillion won, or some 270 billion won a year ^[14][16].

The first claim on the designation goes to capital already committed. The city said it will focus administrative resources in particular on speeding up the investment plans of companies already operating in or committed to the area, POSCO Group affiliates among them ^[4]. The existing base covers lithium and nickel refining and smelting, cathode materials, graphite and used-battery recycling ^[6]. Recruiting firms in equipment, parts, cells, energy storage and recycling, segments the city calls relatively underrepresented, is a parallel aim ^[5].

The city did not say what the water, power and road work around Sepung will cost or who will pay for it ^[3]. It also wants the designation to get its key regional projects written into the central government's development plan ^[3].

One outcome is that the designation mostly ratifies timetables POSCO's affiliates had already set, adding little capital that was not coming anyway ^[4]. Another is that water and power were the real limit, so faster infrastructure pulls committed projects forward and brings tonnage online sooner. A third is that cell and energy-storage makers stay with the complexes in Cheongju, Pohang, Ulsan and Saemangeum, which already focus on cells and materials ^[8], and Gwangyang Bay stays the upstream supplier it is today. I think the first is the likeliest in the next few years, because the city's own priority list starts with firms already on site ^[4]. The second is the strongest counter-case. If pipes and power lines were holding back committed projects, speeding them up is how new capacity arrives.

"With this designation, the Gwangyang Bay area has become a national strategic base responsible for South Korea's battery supply chain," Min Hyung-bae, mayor of Jeonnam-Gwangju Special Metropolitan City, said ^[12]. He added: "Now we must produce results worthy of the name specialized complex" ^[13].
